I Started Using AI to Translate YouTube, Coursera, Udemy, Bilibili, and TikTok Videos — Here's My Experience

Gregory Williams — Tue, 09 Jun 2026 05:29:48 +0000

If you spend a lot of time learning from online videos, you've probably run into the same problem I have:

Some of the best content isn't available in your native language.

Whether it's a YouTube tutorial, a Coursera lecture, a Udemy course, a Bilibili video, or even a TikTok clip, language barriers can make learning slower than it should be.

Recently, I tried a Chrome extension called LingTube, and it turned out to be surprisingly useful for consuming foreign-language video content.

What Is LingTube?

LingTube is a Chrome extension that provides:

AI video translation
Subtitle translation
AI dubbing and voice playback
Speech recognition for videos without subtitles
AI-powered video summaries

What caught my attention is that it's not limited to YouTube.

It currently supports:

YouTube
Coursera
Udemy
Bilibili
TikTok

So the same workflow works across educational platforms, technical courses, and short-form video content.

Works Even When Videos Don't Have Subtitles

One feature I found particularly useful is support for videos without captions.

Instead of relying solely on existing subtitles, LingTube can:

Recognize speech from the video
Convert speech into text
Translate the content
Read the translated text aloud

This makes many videos accessible that would otherwise require manually following fast spoken content.

Bilingual Subtitles

For language learners, bilingual subtitles are a nice touch.

You can display:

Original subtitles only
Translation only
Original + translated subtitles together

This makes it easier to learn technical terminology while still understanding the overall content.

AI Dubbing and Voice Playback

Rather than constantly reading subtitles, translated content can also be spoken aloud using AI voices.

For longer lectures, tutorials, and online courses, this can feel much more natural than reading text throughout an entire video.

AI Video Summaries

Another useful feature is the AI summarizer.

Instead of watching an hour-long video immediately, the extension can generate:

Key takeaways
Important concepts
Technical term explanations
Relevant timestamps

This is especially useful for:

Programming tutorials
Technical talks
Online courses
News and podcast content
Free Credits

The extension includes a free usage model:

New users receive 2 free AI credits after signing up.
Users can claim 1 additional AI credit every day by logging in.
After AI credits are exhausted, the standard translation mode remains available, so the extension is still usable without AI features.

That makes it easy to test the workflow before deciding whether AI features are necessary for your use case.

Who Might Find It Useful?

I can see this being helpful for:

Developers watching foreign-language technical content
Students taking Coursera or Udemy courses
Language learners
Researchers consuming international content
Anyone who regularly watches YouTube, Bilibili, or TikTok videos from creators around the world
Final Thoughts

The internet has an incredible amount of knowledge available, but much of it exists outside our native language.

LingTube helps reduce that barrier by combining subtitle translation, speech recognition, AI dubbing, and video summarization into a single workflow.

If you regularly learn from video content on YouTube, Coursera, Udemy, Bilibili, or TikTok, it may be worth checking out.

How I Use AI to Dub Coursera Courses in Real-Time for Faster Learning

Gregory Williams — Fri, 05 Jun 2026 09:53:19 +0000

Hi everyone! As a developer who constantly learns from overseas tech videos and online lectures, I often face a common hurdle.

When watching English videos on YouTube or deep-diving into high-quality courses on Coursera, chasing translated subtitles can be exhausting. It forces you to constantly look back and forth between the bottom of the video and the instructor's slides or source code.

Recently, I found a browser extension called "LingTube" that completely solves this problem by turning English lectures into natural audio in your native language. I wanted to share my experience with it here!

👉 LingTube Official Website

🚀 Fully Supports Coursera

The biggest game-changer for me is that LingTube officially supports Coursera, one of the world's leading online learning platforms.

If you want to take world-class tech courses from Google, IBM, or top universities but hesitate due to the language barrier, this extension bridges that gap effortlessly. It seamlessly integrates into the Coursera video player to provide both high-accuracy dual-language subtitles and real-time audio translation.

🎧 "AI Real-Time Dubbing" — Keep Your Eyes on the Code

The absolute best feature of LingTube is its AI Real-Time Dubbing (Voice Synthesis).

Instead of just translating text on the screen, the AI translates the English lecture into natural audio in real-time.

Focus 100% on the screen: You no longer need to read tedious subtitles. You can keep your eyes locked onto the instructor's architecture diagrams, PPTs, or live-coding sessions.
Learn via audio: It feels exactly like taking a course taught directly in your native language, which drastically reduces cognitive load and accelerates your learning speed.

💰 Daily Free Credits & Referral Rewards

Even though it uses advanced AI models for both contextual translation and text-to-speech generation, its credit system is incredibly friendly for individual learners:

Get 1 Free AI Credit Every Single Day!
- Just by logging in, your AI usage quota resets by 1 credit daily. If you study at a steady pace of one lecture per day, this free tier is incredibly useful.
Invite Friends for Extra Credits!
- If you share your referral link and a friend installs LingTube, you get an additional AI credit. It is a great win-win mechanism to cycle through your learning goals with peers.

🛠️ Key Features Summary

AI Contextual Translation & Dubbing: Smart, contextual audio generation rather than rigid word-for-word translation.
Coursera & YouTube Integration: Covers major educational and video tech platforms.
Minimalist UI: Clean, non-intrusive design that blends perfectly into video players.

📝 Final Thoughts

In today's tech world, being able to directly consume global learning resources gives you a massive advantage. LingTube acts like your personal, highly capable real-time interpreter sitting inside your browser.

If you have been wanting to level up your skills on Coursera or stay ahead of global tech trends on YouTube without language friction, it is absolutely worth a try.

Unlocking YouTube for Language Learners: A Game-Changing Chrome Extension

Gregory Williams — Sat, 16 May 2026 10:21:51 +0000

If you've ever tried learning a language by watching YouTube videos in your target language, you know the struggle. Auto-generated subtitles are often inaccurate, native speech flies by too fast, and you end up pausing every few seconds just to look up words. What if there was a tool that handles translation, dubbing, and study features right inside the YouTube player itself?
Enter LingTube — a Chrome extension that turns foreign-language YouTube videos into accessible, bilingual learning experiences.
How It Works
Open any YouTube video, click once (or use the handy Alt + Shift + V shortcut), and LingTube does the heavy lifting:

Translates subtitles or speech — even for videos with no captions at all. It transcribes the audio first, then translates it.
Bilingual subtitles — see both the original and translation on screen, or toggle to one side for a cleaner view.
AI dubbing & read-aloud — natural-sounding voices (powered by Edge TTS or browser-native) read the translation aloud while the video continues playing. Perfect for passive listening during commutes.
AI-powered extras — generate video summaries, chat with the content to explain concepts or jump to timestamps, and turn tricky sentences into vocabulary drills, grammar notes, or review prompts.

Cached translations reopen instantly without using extra credits, so revisiting videos feels seamless.
Built for Real Watching Habits
LingTube shines in practical scenarios:

Commuting or hands-free learning: Queue dubbed audio for podcasts, interviews, or long-form content.
Shadowing practice: Listen to the original, glance at the translation, then repeat after the AI voice.
Deep dives: Pause on dense technical tutorials, anime, news, or courses and instantly get explanations or study aids.

It supports a wide range of languages and works directly on the YouTube page you're already on—no need to copy links or switch apps.
Who It's For
Language enthusiasts, students tackling foreign tech tutorials, professionals keeping up with international news, or anyone who wants to consume authentic content without the constant subtitle battle. Whether you're into anime, programming lectures, or global vlogs, it makes "immersion" actually enjoyable.
The extension is free to install and try, with simple monthly ($5) or yearly ($40) plans for unlimited AI usage. Cached content doesn't eat into your quota.
Try it yourself: Head to lingtube.xyz to grab the Chrome extension and see the live demo.
If you're serious about making YouTube part of your language routine, this might be one of the most practical tools out there right now. Have you used similar extensions? What features would make video-based language learning even better? Share in the comments!

Move People or Objects Inside a Photo Using AI (Free, No Signup, Browser-Based)

Gregory Williams — Tue, 24 Mar 2026 19:02:28 +0000

Sometimes when looking at a photo, the problem isn’t what’s in it — it’s where things are placed.

A person is too close to the edge
A product isn’t centered
The composition just feels slightly off

You don’t want to remove anything. You just want to move it.

This post walks through a simple way to move a person or object within the same image, using a browser-based tool (free, no signup required).

👉 https://editghost.xyz/guides/how-to-move-a-person-or-object-in-a-photo

What’s actually happening behind the scenes

The workflow is basically:

Select (cut out) the subject
Fill the original background
Reposition the subject in the same image

So instead of deleting something, you're doing:

cut + background repair + reposition

Step-by-step

1. Upload your image

Open the tool and upload your image.
No account, no setup — just drag and drop.

2. Select the subject (important)

Instead of marking what you want to remove,
👉 select what you want to keep and move

Tips for better results:

Trace edges carefully
Be slightly generous around hair or fine details
Avoid including too much background

Selection quality directly affects the final result.

3. Cut out + background fill

Once processed:

The subject is cleanly extracted
The original area is automatically filled

Ideally, it should look like the subject was never there.

4. Move it inside the same image

Now you can drag the subject and reposition it.

You can adjust:

Position
Scale
Rotation

Tips to make it look natural

This is where most results succeed or fail.

Don’t move too far

This works best for small composition tweaks, not big relocations.

Match the scale

If the size doesn’t match the perspective, it’ll look pasted.

Watch ground/contact points

Feet, shadows, or surfaces matter more than you think.

Simple backgrounds work best

These tend to give cleaner results:

Walls
Floors
Sky
Tables
Grass

When this is useful

This isn’t meant for heavy compositing. It’s great for:

Thumbnail adjustments
Product image tweaks
Social media composition fixes
Creating space for text

Basically:

“I like the photo, just not the layout.”

Final thoughts

This approach combines:

Subject extraction
Background inpainting
Repositioning

…into a single, lightweight workflow.

And since it runs in the browser, is free, and requires no signup, it’s easy to try without any setup.

If you’ve ever wanted to adjust composition without opening Photoshop, this is a pretty practical option.

A Simple Way to Edit Just Part of an Image (Without Rebuilding Everything)

Gregory Williams — Tue, 24 Mar 2026 03:34:23 +0000

Sometimes you look at an image and think:

“This is fine… except for that one part.”

Maybe:

You want to change the color of a shirt
Replace a small UI element
Slightly blur the background
Fix a distracting detail
Recreating the entire image feels unnecessary. What you really want is to edit just a specific area—cleanly.

A tool I tried for this
I recently tested this:

👉 https://editghost.xyz/use-cases/ai-magic-editor

It runs directly in the browser, and you can use it for free without signing up, which makes it easy to experiment.

How it works (quick overview)
The workflow is pretty straightforward:

Upload an image
Paint over the area you want to change
Describe what you want
Generate
Step 1: Mask the area
You start by marking the part you want to edit.

The key here is:

Be precise, not excessive.

If you select too large an area, the result can feel off.

Step 2: Describe the change
Next, you just describe what you want.

Examples:

“Change the shirt to blue”
“Blur the background”
“Replace the screen with a different UI”
You don’t need complex prompts—simple intent works fine.

Step 3: Check the result
The tool generates a new version with your change applied.

It’s usually not about getting it perfect in one try. Tweaking the mask or prompt slightly often gives better results.

When this works well
From my experience, this kind of tool is best when:

The image is already usable
You only need small adjustments
You want to avoid breaking the overall composition
Good use cases:

UI mock tweaks
Product image cleanup
Minor visual corrections
Color adjustments
When it’s not ideal
If you want to:

Completely redesign the image
Generate something from scratch
Then a full image generation workflow might be more suitable.

Final thoughts
This isn’t about flashy transformations.

It’s more about:

Making small, controlled edits without introducing weird artifacts

The fact that it’s free and doesn’t require registration makes it a nice tool to keep around for quick fixes.

Remove Image Backgrounds in Your Browser (No Signup Needed)

Gregory Williams — Sat, 21 Mar 2026 17:08:50 +0000

There are plenty of situations where you just want the subject of an image—nothing more.

Maybe it’s a product photo for a listing, a quick profile picture cleanup, or a visual for a presentation slide. Traditionally, you’d open something like Photoshop for this. But for simple cases, that’s often overkill.

Recently, I tried a browser-based tool that handles this pretty smoothly:

No installs, no account, and it works directly in your browser.

Here’s how the process looks in practice.

When this kind of tool is actually useful
From testing, it works best in everyday scenarios like:

Cleaning up product photos
Removing backgrounds from portraits
Creating thumbnails or simple banners
Preparing images for slides or docs
Quick assets for marketplaces
If the subject is clearly separated from the background, results tend to be surprisingly solid.

Step-by-step: removing the background

Upload your image Start by uploading a JPG or PNG.

A small tip: images with sharp edges and good contrast between subject and background tend to work better.

Select the subject Switch to the background removal mode and focus on selecting what you want to keep, not what you want to delete.

Most tools (including this one) give you a few options:

Auto selection (quick and decent for simple images)
Brush / paint selection (better control for tricky edges)
Box selection (good for products or simple shapes)
Don’t try to be perfect right away—rough selection first, refinement later is faster.

Refine the edges This is where the final quality comes from.

Clean up any leftover background around the edges, especially:

Hair
Shadows
Transparent or reflective areas
Even small adjustments here make a big difference in how natural the result looks.

Remove background and export Once everything looks good, remove the background.

You’ll typically get a transparent PNG, which is ideal because you can reuse it anywhere.

Optional: try different backgrounds
One thing I found useful is testing the cutout on different backgrounds (light and dark).

Sometimes edges look fine on white but slightly off on darker colors. It’s a quick way to catch imperfections before using the image elsewhere.

Tips for better results
A few things that made a noticeable difference:

Use clear source images
Blurry or low-contrast images make background removal harder—no matter the tool.

Work in two passes
Start rough → then refine. Trying to be precise from the beginning usually slows things down.

Check on multiple backgrounds
Helps spot edge artifacts you might otherwise miss.

What works well (and what doesn’t)
Works well:
Product photos
Portraits (especially upper body)
Simple or clean backgrounds
Clear subject outlines
More challenging:
Fine hair details
Glass / transparent objects
Strong shadows
Motion blur
Similar colors between subject and background
It’s still usable in those cases, just expect a bit more manual cleanup.

Final thoughts
For something that runs entirely in the browser and doesn’t require signup, this kind of tool is surprisingly practical.

It won’t replace full editing software for complex work, but for quick background removal, it gets the job done without friction.

If you just need a clean cutout without opening heavy tools, it’s worth trying: https://editghost.xyz/use-cases/remove-background-from-image

If you want, I can also tailor this for SEO (titles/tags for Dev.to) or make a more technical/dev-focused version.

I Built a Fast Gemini Watermark Remover (No Upload, No Signup) — Here’s How It Works

Gregory Williams — Tue, 17 Mar 2026 12:23:02 +0000

The Problem I Kept Running Into
If you’ve been experimenting with Gemini image generation, you’ve probably hit this:

You generate something great… and then a watermark (or random artifact) ruins it.

This kept happening to me.

Especially with:

Gemini watermarks
The weird “Nano Banana” marks
Random objects or glitches in generated images
I just wanted a quick way to clean things up.

Why Existing Tools Didn’t Work for Me
I tried a bunch of “AI watermark removers”.

Most of them had the same issues:

Too slow
Required full image uploads
Overly complicated UI
Not optimized for quick edits
For something that should take 5 seconds, it felt like too much friction.

So I Built My Own
I ended up building a small tool:

👉 https://editghost.xyz

Originally, it was just for cleaning Gemini images.

But over time, I started using it for:

Travel photos
Product mockups
Random screenshots
⚡ What Makes It Different
Instead of being another heavy AI tool, I focused on:

Speed first
Minimal UI
No signup
Mostly browser-based
The goal was simple:

Open → mark → remove → done

🔥 Demo: Removing a Gemini Watermark
Before / After

✏️ Removing Objects with a Brush
You can just paint over the area:

And the AI fills it naturally:

🌍 Not Just for AI Images
I didn’t expect this, but it works well for:

Removing people from travel photos
Cleaning backgrounds
Erasing text or distractions

🧩 Current Features
Right now it supports:

Removing Gemini / Nano Banana watermarks
Object removal (people, text, wires, etc.)
Brush-based selection
Natural content filling
Adding text or overlays
🔒 Built for Speed (and Privacy)
One thing I cared about a lot:

Reducing friction.

No login required
No heavy uploads
Fast processing
Since most of it runs in the browser, you don’t need to send large files to a server.

🛠️ How I Use It
Personally, I use it almost daily for:

AI-generated images
Travel photos
Quick visual edits
It’s become one of those “always open in a tab” tools.

🙌 Would Love Feedback
If you try it, I’d love to know:

Is the use case immediately clear?
What’s missing?
Things I’m considering next:

Batch processing
Better masking tools
Faster performance for large images
Also curious:

Does the browser-first / privacy angle matter to you?
