I Built an AI Name Generator for Literally Anything

Jiajun Yan — Thu, 27 Mar 2025 13:59:46 +0000

Hey guys,

I built Any Name Generators to help people instantly generate names for any apps, fantasy characters, projects, domains, you name it.

It’s fully AI-powered, works in multiple languages, and doesn’t require sign-up. You just describe what you need (e.g. “cyberpunk hacker alias” or “cute brand name for pet toys”), set how many names you want, and hit generate.

I also added some niche generators—like for knights, druids, demons, etc. because sometimes you just really need a solid mage name.

It’s 100% free and built for speed. Let me know what you think or if there's a name type you'd like added.

I Made a Dungeons and Dragons Name Generator to Help You Create Perfect Character Names!

Jiajun Yan — Thu, 09 May 2024 14:11:15 +0000

As a developer and a Dungeons and Dragons enthusiast, I wanted to make it easier for players to come up with cool, fitting names for their characters. That's why I created the Dungeons and Dragons Name Generator. It's a simple tool that helps you find the perfect name based on your character's gender, class, race, and personal traits. Whether you're a seasoned player or just starting out, this tool is designed to spark creativity and add depth to your role-playing.

The Dnd name generator is straightforward: you input details about your character, choose how many names you want to see, and even add a custom message to get names that feel just right. I built it to blend seamlessly with D&D's lore, making sure each name feels authentic. It's rewarding to see other players use this tool to enhance their games and bring their characters to life.

I Made a Harry Potter Name Generator to Create My Hogwarts Legacy Character!

Jiajun Yan — Fri, 03 May 2024 08:00:48 +0000

I just built an exciting tool for all the gamers and Harry Potter fans out there—the Harry Potter Name Generator! As a developer and a fan myself, I noticed how challenging it can be to create a name that not only sounds magical but also truly fits into the wizarding world. This inspired me to develop a solution that enhances the gaming experience by providing a seamless way to generate character names that resonate with J.K. Rowling’s universe, especially useful for games like Hogwarts Legacy.

The Harry Potter Name Generator is a user-friendly tool designed to help you craft a character that feels right at home in Hogwarts. Simply choose your character's gender, select a Hogwarts house, and enter any specific traits or themes you'd like your character's name to reflect. The generator then works its magic to offer a variety of names that are both unique and fitting, adding a personalized touch to your game character’s identity and enriching your storytelling in the magical world.

A Font Changer to Personalize Your Web Experience

Jiajun Yan — Tue, 09 Apr 2024 14:31:03 +0000

Hey everyone,

I'm just a regular guy who spends way too much time online. Whether it's scrolling through articles, binging blogs, or just doing some work, I realized something – the web can be a pretty dull place, visually speaking. Ever got tired of staring at the same old fonts and colors on every site? Yeah, me too.

That's why I created BetterFont. It's a simple idea, really: let's make the web a bit more us. With BetterFont, you can change fonts, tweak colors, adjust spacing... all that good stuff, directly in your browser. No coding, no fuss. Whether you need bigger fonts to read comfortably, or you're just in the mood for a change, BetterFont's got your back.

I made BetterFont for two main reasons: 1. To give you (and me) the freedom to see the web in a way that suits us better. 2. To save our eyes from the monotony of the same look every webpage offers.

I genuinely hope BetterFont makes your web browsing more enjoyable and personal. Keen to hear what you think and looking forward to your feedback!

Cheers!

AI question generator for teachers

Jiajun Yan — Thu, 11 Jan 2024 01:56:58 +0000

I recently made an app called HyperQuiz - an AI question generator for teachers.

You can save time from generating questions for quizzes, exams and worksheets from any YouTube videos and text sources with AI.

Questions including multiple choice, true/false, open-ended and a lot more can be auto generated based on the text given or a youtube video.

Check it out now: HyperQuiz.

I build a tool with Next.js to quickly organize ideas into structured notes!

Jiajun Yan — Wed, 06 Dec 2023 02:52:19 +0000

First of all, here's the app：Echonotes.

I often have a lot of ideas that I want to record immediately, but handwriting them or manually typing them can easily cause me to miss many good ideas because the efficiency is too low.

Therefore, I made an app that allows me to record ideas promptly, ensuring I don't miss any of them.

At the same time, I also added some AI features to this app, such as converting ideas into tweets, Instagram captions, or emails, etc. When writing, I can also ask AI for inspiration.

This app is still in its early stages, so I am constantly improving it. I hope to receive your valuable suggestions.

If you have any constructive suggestions, please feel free to put them forward, and I will continually improve the app.

Thank you.
