xiaotong zhang — Fri, 06 Nov 2026 07:55:16 +0000

Want to build books and ready‑to‑print KDP covers without jumping between multiple tools? OneKDP is an AI‑powered book creation workspace built for indie authors and self‑publishers.
🔗 https://onekdp.com/

You can generate editable book interiors, design full print‑wrap KDP covers, or make both inside the same workspace. It supports novels, workbooks, coloring books, puzzle books, journals and planners.

Simple workflow:

Describe your book: pick book type, language, trim size, title, topic and target readers.
Choose what AI generates: cover only, interior only, or full complete book.
Manually edit text, page layouts and cover design after AI generation.
Run preflight checks and export print‑ready PDF files for KDP upload.

Key highlights:
✅ Generate complete print‑wrap covers including front, spine and back cover
✅ Supports many book formats: fiction, non‑fiction, activity books, planners and more
✅ Keep editing everything after AI output; you retain full control over final content
✅ You can import your existing cover or manuscript and only generate the missing part
✅ Built‑in free publishing calculators and manual editing tools
✅ Multi‑language workspace interface
✅ Manual editing & calculators are free; AI generation consumes credits

AI output serves as a starting point. Always review text, facts, layout and artwork before you publish to KDP.

If you are an independent author preparing files for Amazon KDP, give OneKDP a try!

Is your Android TV or Google TV cluttered with annoying promoted content and pre-installed apps you never use? CleanYourTV.AI helps you tidy up your TV home screen, manage ads and bloatware — no root required.
🔗 https://cleanyourtv.ai/

It works with Android TV and Google TV, and has limited support for Amazon Fire TV. You can run it from Mac (Apple Silicon / Intel), Windows PC or an Android phone.

The workflow is straightforward:

Download the companion app for your device.
Connect to your TV on the same Wi‑Fi network, enable TV debugging.
Preview changes, pick layouts, wallpapers and themes, then apply them.

What it can do:
✅ Simplify your TV launcher, put your favourite apps front and centre
✅ Reduce system ads and hide unwanted pre-installed clutter
✅ Apply ready-made TV themes, fresh wallpapers and home screen layouts
✅ Keep core TV functions: streaming, HDMI, casting, voice control still work
✅ Every change can be reviewed, logged, and easily undone
✅ Privacy-focused controls for your TV

You can see a clear before-and-after: the messy stock TV home screen full of promotions turns into a clean, minimal interface with only the apps you want.
It does not require coding skills or complicated setup.

There is a free trial available, and paid Plus plans unlock full apply features.

If your TV home screen is a chaotic mess of ads and preloaded apps, give CleanYourTV.AI a look!

Turn Any Image Into A Giant Wall Poster With This Free Block Poster Maker

Want a huge wall art poster, but you don’t have a large-format printer? BlockPoster.ai solves this perfectly.
🔗 https://blockposter.ai/

It is a browser-based block poster maker. You upload one single image, and the tool automatically splits it into regular printer sheets like A4 or US Letter. After printing, trimming and taping them together, you get a big tiled wall poster.

The workflow is simple:

Upload your own image, or generate artwork directly with its built-in AI.
Adjust poster size, paper type, margins and overlap settings. You can preview the layout live.
Download the split multi-page PDF file.
Print all sheets on your home printer, trim, align and assemble your giant poster.

Best features I noticed:
✅ Local photo processing: Your images are decoded and split right in your browser. Files won’t be sent to outside servers.
✅ Free tier available: You can export a sample PDF to test without signing up.
✅ Multiple paper sizes supported: A4, US Letter, A3, Legal, Tabloid. Portrait and landscape orientation.
✅ Overlap and trim guides built in, to help you line up pages easily.
✅ No software installation needed, works in any modern browser.

It’s great for classroom displays, DIY wall decor, event backdrops, craft projects and big maps.

Important note: The free version adds a small brand watermark. For watermark-free HD downloads, you can upgrade to their paid plans.

If you love DIY wall art and only own a regular home printer, give BlockPoster.ai a try!

Tired of guessing if a new hairstyle suits you? Try this AI hairstyle preview tool

Tags: ai, tools, web, beauty

Ever scroll through Pinterest or Instagram, save a gorgeous hairstyle, then panic right before your salon booking — will this actually look good on me?

I found a neat browser AI tool that fixes that guesswork: AI Hairstyle Changer.
🔗

No downloads, no complicated setup. Just upload a clear front portrait photo, and you can test over 100 hairstyles and 20 different hair colours in seconds.

It covers tons of styles: bobs, lobs, short cuts, layered waves, curly hair, braids, ponytails, plus solid colours and gradient highlights. You can even upload a separate reference photo and ask the AI to replicate that exact hairstyle on your face.

The whole process is simple:

Upload your portrait photo
Pick hairstyles or hair colours you want to try
Generate the preview (takes less than 30 seconds)
Compare side-by-side before/after shots and save your favourites

What I love most: you get one free preview without signing up. It prioritizes privacy, and everything runs in your web browser.

This is such a game-changer for salon communication. Instead of showing your stylist a photo of a different person, you can bring your own preview image. It helps you both align on length, layers, bangs and colour, and avoid that “this isn’t what I wanted” moment.

Quick disclaimer: This is only an AI simulation. Your real hair texture, density and natural growth pattern will change the final salon result. It’s a planning aid, not a perfect prediction.

If you’re itching for a hair makeover but scared to commit, check it out!
