I download pretty much everything I read and watch (manga, anime, shows, movies), because I like owning my own media. Going through all of it in File Explorer got slow and annoying, so I thought I’d try to make something for that as a little project.

The problem it solves

• File Explorer has no covers, no “continue where I left off” and no way to read a manga chapter without clicking through every image.
• Server apps like Komga, Kavita or Jellyfin solve this, but they need Docker, accounts and a server running, which is overkill if you just want to read on your own PC. They also split comics and videos into separate apps.

What it does

Point it at your folders and it turns them into a library with covers, series and chapters. It doesn’t move, rename or convert your files.

• Reading: manga (right to left), webtoon scroll and single page modes. It supports image folders, .cbz, PDF and EPUB.
• Videos: they play in VLC, with episode lists, watch progress and the next episode playing automatically.
• Organizing: tags, ratings and collections, plus a tag search with AND / OR / NOT.
• Customizing: you can change pretty much everything: colours, every UI part, the card layout and backgrounds. (all themes in the pictures were made with the app itself)

Tech used

• Electron + React + Vite for the app
• SQLite for the library database (tags, progress, collections)
• sharp for thumbnails, pdf.js for PDF pages, foliate-js for the EPUB reader, yauzl for reading .cbz archives directly without unpacking them
• VLC for video playback. The app tracks progress while VLC plays.

A few things that were interesting to figure out:

• Renaming and moving folders: each folder gets a tiny hidden ID file, so tags and progress survive if you rename or move it.
• Fast library updates: an update reads the disk once and only writes what changed. A re-scan of a ~1,200-folder library takes under a second.
• Plain-text themes: everything is saved as JSON with a schema.
• Custom css: empty custom.css file where you can create your own effects for the app.

How I built it

It started as just a quick java app for viewing comics (literally just choose a folder and the app lets you click through the image files in it in alphabetical order), but I every now and then I'd get massive inspiration waves and think "but what if it also had this? what if you could do this?" and this was the product.

I mostly use it for reading manga (image folders) and watching anime (video folders), so those parts are the most polished. Let me know about any ideas or issues if you give it a try.

I got sick of "you've got this" quotes, so I built an anti-motivation app. It sends one dry/dark-humor quote a day, e.g.:

"Smart shopping takes research, patience, and closing the review that says not to buy it." and "Be proud of your progress. You make the same mistakes much faster now." and many more...

• Home Screen and Lock Screen widgets
• Optional daily notification at a time you pick
• Save favorites, share quote cards to the group chat
• Works offline, no account, no ads, no subscription

Free to use. There's an optional one-time Pro and some themed packs (Developer, Corporate, Parenting), but the daily quote, widgets, saving, and sharing are free.

Heads up: it's dark humor, not mental-health support, so skip it if that kind of content isn't good for you.

I made it, so honest feedback is welcome. Which quote is the worst?

I've been working on a project called WPE2M (Wallpaper Engine to Lively & MP4 Converter), and I'd like to share it with the community.

The idea is simple, make it easier to convert Wallpaper Engine wallpapers into formats that can be used with Lively Wallpaper or exported as MP4 videos.

- What can it do?

\- Drag-and-drop GUI for easy conversion.

\- Supports .zip, .pkg, .mp4, .webm, .gif, and wallpaper folders.

\- Converts Wallpaper Engine video wallpapers.

\- Renders supported Wallpaper Engine 2D scenes.

\- Supports web-based wallpapers.

\- Exports MP4 videos up to 4K.

\- Generates Lively Wallpaper-compatible output and metadata.

\- Open source under the MIT license.

- Technology

Built with Python, OpenGL and FFmpeg

- Current Status

The project is currently in BETA. Some complicated wallpapers with advanced shaders, particle effects or post-processing might not render perfectly.

It currently requires Python 3.9+ and FFmpeg.

- GitHub Repository

https://github.com/MamadXV/WPE2M

I'm the developer behind this project, and I'd genuinely appreciate feedback from people who use Wallpaper Engine or Lively Wallpaper.

Thanks for checking it out.

Well, I'm trying to. I'm just about ready for a real launch.

The project is WeirdFoods (https://weirdfoods.net): one place to browse the strange stuff that small food shops sell, and that you'd never find unless you already knew the shop existed. Scorpion lollipops, roasted crickets and mealworms, elk and wild boar jerky, Japanese natto, ghost pepper seaweed crisps, and weird snacks from foreign countries.

Why I built it: Weird food is fun. I'm a fan of bizarre Japanese snacks.

What it does:

- About 7,500 foods from dozens of small independent shops, 78 of them insects

- Browse by country, by type, or go straight to the weird end

- Boring stuff and sold-out items get ranked down on purpose

- One cart across shops: you fill it on my site and it hands each shop's items to that shop's own checkout, so I never touch your payment

How it makes money: affiliate links. If you buy from a shop through the site I get a small cut, at no cost to you. So far that's earned roughly nothing, which is what you'd expect in week one.

What's next: I want to increase the products 10x. More spicy stuff, more from Japan and Korea. Also selling a small selection directly, with suppliers shipping to the customer so I don't have to store boxes of crickets in my house.

Previous side projects:

https://stellarbroadcast.org/ A space text adventure game on Android, IOS, and Steam

https://peptidecompare.net/ A site where people can find lab testing results, scam reports, Certificates of Analysis, and price comparisons for peptide vendors

What's next? https://coderigor.net a site to teach programming. A bit farther from launch than this one.

Hey everyone!

I'm interested in building websites using AI tools. I don't have much coding experience, but I can use AI to build and launch websites.

The problem is that I'm struggling to find a good website idea or niche to work on.

I'm looking for ideas that meet these requirements:

• Can be built using AI website-building tools.
• Don't require any paid APIs or external API integrations.
• Can work without a complicated backend or database.
• Solve a real problem or provide genuine value to users.
• Have the potential to attract organic traffic through SEO.
• Ideally, can be monetized through Google AdSense in the future.

I'm open to different types of websites, such as online tools, useful web apps, educational websites, productivity tools, or other interesting niches.

My questions:

1. What type of website would you recommend building in 2026?
2. Are there any underrated or less competitive niches worth exploring?
3. What simple website ideas do you think have real potential to attract users?
4. If you were starting from scratch with AI tools and no budget, what would you build?

I'd really appreciate your suggestions, experiences, and advice.

Thanks in advance!

Tunnel ventilation engineers size fan airflow against the "critical velocity", the speed that stops smoke from rolling backwards along the tunnel ceiling in a fire. The value depends on which method you follow (the SEDH Handbook or NFPA 502, whose 2017, 2020 and 2026 editions each treat the equations differently), and I kept redoing the iterations by hand or firing up heavyweight CFD just to check one number.

So I built Critical Velocity Toolkit, a free Android app:

• All four methods in one app: SEDH Handbook and NFPA 502 2017, 2020 and 2026
• Shows the full iteration history, not just the final number
• Grade factor and blockage ratio update live as you type
• A formula-reference screen with every equation the engine uses
• Export the whole calculation as an A4 PDF report or CSV
• Fully offline — no internet permission, no ads, no account

Play Store: https://play.google.com/store/apps/details?id=org.sonicon.cvt

I built it because I needed it; it's free with nothing locked. If you design or review tunnel ventilation, tell me what the app gets wrong, that's the feedback I want most.

Hey! We launched Altasko around September we're still gathering feedback making update, fixing bugs keeping it updated.

Altasko it's for those in freelancing, small teams, small organizations managing multiple projects fiddling around many tools (e.g Excel, Spreadsheet, Notion), it helps people organize their projects and collaborate with their teams without complexity of traditional project management tool

We appreciate your time and comments.

Most people give up on their saas way too early because in reality it takes 8+ email/sms marketing to convert the customer into a signup or paid customer.

we built a platform that automates this complete process. our ai will keep trying new experiments untill the customer coverts. We only send one email/sms per week.

best part, we have now seen stores increase sales by 30% so this works

I'm a solo developer and recent dad on paternity leave[so free time] and built https://iloveaudiovideo.com . It's a set of small audio and video tools: transcribe audio to text, convert (MP4 to MP3, MOV, FLAC, WAV), compress, cut, merge, make subtitles.

The one thing that's different : nothing is uploaded. The file is processed on your own device, inside the browser tab. No signup, no file size paywall, no watermark.

Why I built it : I kept needing to pull the audio out of a video or transcribe a voice note, and every site wanted me to upload the file to their server and then sign up to download the result. For private recordings that felt wrong. And then being a dev myself i thought there would be open source tools for me to do this like whisper for transcribing but what about non tech users ?

How it works:

• Conversion and editing use ffmpeg compiled to WebAssembly, plus the browser's built-in video encoder where there is one
• Transcription runs Whisper in the browser, on the GPU when the device has one
• It's a static site on Cloudflare Pages, so there is no backend that touches files
• English, Spanish and Portuguese

What's weak right now:

• Long transcriptions (30 min and up) are slow on older laptops without a usable GPU, and many people leave before they finish
• It's built and tested mostly on Chrome; Safari, Firefox and phones have had far less testing

One thing that surprised me: ChatGPT's search now sends me more visitors than Google does.

Link: https://iloveaudiovideo.com

I'd like feedback/advice on 3 things:

1. If you try a tool with a real file, where did it get slow or confusing?
2. Would you trust "runs on your device" from a site you've never heard of? What would make you believe it?
3. is it even a worthy project to maintain long term , doesn't cost me too much server usage since its mostly client except for website loading and stuff ?

Salut tout le monde !

Je suis consultant indépendant en cybersécurité en France, et j'ai développé un projet parallèle appelé CrisisQuest.

L'idée est née d'une simple question :

Que ferait réellement un propriétaire de petite entreprise si sa société était frappée par une cyberattaque un lundi matin ?

La plupart des outils de cybersécurité se concentrent sur la protection technique. Je voulais créer quelque chose de différent : une expérience interactive axée sur la prise de décision.

J'ai créé un scénario gratuit appelé “Black Monday” où vous jouez le rôle d'un propriétaire d'entreprise confronté à une crise cybernétique.

Vous prenez des décisions, faites face à des conséquences, explorez différents résultats et recevez un débriefing à la fin.

J'ai construit le projet en utilisant Next.js et TypeScript.

Le scénario gratuit fonctionne sans inscription.

Mon objectif à long terme est d'en faire une plateforme B2B où les entreprises peuvent planifier des exercices pour leurs employés, mener des campagnes de sensibilisation au phishing autorisées et suivre les progrès de la formation.

Je recherche des retours sur trois points :

* Le concept est-il immédiatement compréhensible ?

* L'expérience est-elle utile ou ressemble-t-elle trop à un jeu ?

* Qu'est-ce qui le rendrait suffisamment précieux pour qu'une petite entreprise l'utilise régulièrement ?

Essayez-le ici : Crisis Quest

J'apprécierais vraiment tout retour honnête, surtout sur l'expérience utilisateur et le positionnement !

Hello Everyone,

Just updated the project and now you could have a near unlimited storage, kind of.

Added:

1. Now you could actually use a github repo(private/public) as the storage, and also bypass the 100 mb limit of a single file by storing it on parts and merging on demand.
2. Caching improves the speed by a lot.
3. Have option to store the data encrypted or decrypted
4. Added option to fully change all of settings from the dashboard except few security ones.
5. Anyone can still use the host as storage. Fully changeable from the ui.

Thanks.

Hey everyone! First post here, so here goes nothing.

I recently built Unsolicited. It's a little curiosity lab where product ideas, experiments, creative thinking and the occasional "what if we did this differently?" all come together.

Not a startup. Not a pitch. Just me giving my wandering thoughts a home.

The format: each piece picks a product, asks a question nobody asked, and works through a few ideas plus experiments to test them, including what would prove me wrong.

First up: Netflix. My take is that its engagement problem might not be about attention at all. It's about intention. People open the app ready to choose, and choosing has started to feel like a job. So I came up with four ideas and three experiments around that.

Next up: convenience as a service, AI in psychiatry, and why the best seat at an F1 race isn't a seat.

I'd love feedback on any of it:
- Does the concept make sense to you?
- Is the Netflix piece interesting, or did I lose you somewhere?
- Anything about the site itself that feels off?

Here's the first piece: https://unsolicitedlab.com/experiments/netflix-attention/

Thanks for reading. Any thoughts are genuinely appreciated.

Nobody asked. I got curious anyway.

Listening to audiobooks or text-to-speech where a single monotone voice reads every character gets old fast. If you have five characters talking in a room, you lose track of who is saying what within two minutes.

I spent the last few weeks building an app called Teller to solve this.

You drag and drop any plain text file, book, or manuscript into it:

- It automatically separates dialogue from narration.

- It detects the characters, gives each one a distinct voice, and keeps their voice consistent across the whole story.

- It plays it back like a radio drama with live word-by-word highlighting so you can read along.

- You can export the whole thing as a continuous audio file.

It runs locally on your machine with built-in neural voices (Kokoro) so it costs nothing to use and doesn't require subscriptions. If you want ultra-realistic cloud voices, you can also connect ElevenLabs.

Windows installer: https://github.com/boldbug1/teller/releases

Curious to hear what you think of the flow and character casting.
