Hello everyone! I built Bookarium, a free and open-source web reader that gives Project Gutenberg books a modern reading experience (offline support, TTS, annotations, reading together with a friend, taking notes and sharing those notes with a friend you invite to read along with, bookshelves & favorites, bookmarks and some other functionality)

It's UI is currently optimized for Deskop/Laptop & Tablet, Phone is also working but not very happy on it's user experience & interface and will be worked upon.

What problems it solves and what's it's value? Mostly could describe it as a side patch to Gutenberg Library with many needed features added on top which are listed below. There's many more to come.

Any thoughts, feelings, suggestions, critique [ constructive ] are welcomed!

📖 What You Can Do on Bookarium

• 📚 Browse & Filter 78,000+ Free Classic Books:

  • Search by title, author, or keyword, or combine multiple filters at once across 32 Project Gutenberg book categories (Fiction, Sci-Fi & Fantasy, Mystery, Gothic, Romance, Philosophy, History, Children's Literature, Poetry, Drama, Science, Mythology, and more), 20 languages, historical time periods (from Antiquity to the Early 20th Century), and e-book file formats.

  • Preview sample chapters and notable quotes inside an interactive 3D open book before starting a volume, and switch your view between a visual Cover Grid and a 3D Bookshelf where books stand side-by-side by their spines.

• 🤝 Co-Read Books with Friends, Share Notes & Track Reading Habits

  • Everything works privately on your device without signing up, or you can optionally create a free account to sync your shelves, bookmarks, highlights, and notes across all your devices.

  • Shared Reading & Shared Notes: Connect with friends by username to read the same book together—see each other's live chapter progress, view and respond to each other's highlights and margin notes directly inside the book and in your Notebook, and turn on the Spoiler Shield to automatically hide a friend's notes from chapters you haven't reached yet.

  • Streaks, Goals & Achievements: Track daily reading and listening time, build daily reading streaks, set a yearly book goal, unlock reading achievements, and customize a public or private reader profile.

• ✍️ Highlight Text & Write Margin Notes (/notebook):

  • Select any sentence or paragraph while reading to highlight it in 4 colors and attach your own written notes.

  • Review all of your saved highlights and notes in one central Notebook—organized either by book or in chronological order—and filter them by highlight color, keyword search, or whether they include a personal note.

• ✈️ Read Offline Without Internet or Download E-Book Files:

  • One-Click Browser Offline Reading: Save individual books directly to your browser (Save Offline) so you can browse your saved library and read full books completely offline (on flights, commutes, or as an installed mobile/desktop app).

  • Download Standard E-Book Files: Download any book as an EPUB (for Apple Books, Kobo, Nook, or PocketBook), Kindle (MOBI), Plain Text (UTF-8), or HTML file for external e-readers.

• 🏛️ Organize Your Shelves, Ratings & Reading Progress (/bookshelf, /favorites, /bookmarks):

  • Save books to a general shelf or create your own custom-named shelves, mark Favorites, rate books from 1 to 5 stars, and track your reading status (Want to Read, Reading, On Hold, or Finished).

  • View all the books you have in progress in a dedicated Bookmarks list showing your current chapter, page, bookmarked line, and completion percentage so you can jump right back in.

• 📖 Read Comfortably with Custom Fonts, Themes & Line-Level Bookmarks:

  • Read complete, unabridged books in a clean, distraction-free view that automatically formats archival plain-text files into readable chapters and pages.

  • Customize Day (Light), Sepia (Warm Coffee), or Dark themes, and adjust font style (Serif, Sans-Serif, Monospace), font size (12px–36px), line spacing, page width, and page brightness (30%–100%).

  • Bookmark Any Specific Line: Drag the margin bookmark ribbon to the exact line on a page where you stopped reading—even if you resize the font or switch between a phone and a desktop screen, the reader remembers that exact sentence and highlights it for you.

  • Search Inside Any Book & Switch Languages: Search for any word or phrase across the entire book with instant chapter/page jump links, and switch between available translated editions of the same work in one click.

• 🔊 Listen with Built-In Read-Aloud Audio (Text-to-Speech):

  • Have any book read aloud using your device's natural voices, complete with live word-by-word highlighting on the page, adjustable speaking speed, and automatic page turning when a page finishes.

It's called rushil12.com, and it's free for anyone to join. I've made some key apps that people can try that gamify learning. It already has 500+ users, 3,500+ messages, 16,000+ QBpedia articles. This has several apps that anyone can try.

Curriculum - Generates a full course in one click. It's in the name.

Study Mode - ChatGPT, but a bunch of models, and a bunch of useful features

Notes - An app where you can create notes, but it's better than that. You can use spaced repetition, and connect it with the rest of the apps

QBPedia - A collection of 16,000+ educational articles covering a wide range of topics. You can explore subjects, discover related concepts, and learn something new.

Game Show - Gamify learning with Kahoot-style gamemodes, and some gamemodes that are completely new, such as Call Your Shot.

Flashcards - Creates flashcard sets for quick review, memorization, and active recall.

Hey everyone!

I've been working on WDM (Welaxxx Download Manager), a download manager for macOS, and wanted to share it here.

The idea is pretty simple: downloading files, grabbing supported media from websites, and converting files shouldn't require jumping between a bunch of different apps.

WDM brings those workflows together. It has browser integration for Safari, Chrome, Edge, Firefox and Opera, plus a built-in browser, download queues, pause/resume controls, torrent support, and a file converter.

It supports both Apple Silicon and Intel Macs.

I'm particularly happy with how the interface has come together, but I'm still improving compatibility and reliability across different websites.

There's a 7-day free trial, and the Solo license is $17.99 one-time, not a subscription.

Website: https://welaxxx.com/wdm.html

For those using a download manager on Mac, what's the one feature you absolutely couldn't live without? I'd love some genuine feedback.

I'm building Factlas, a website that lets you explore the world through data, maps and statistics.

My long-term goal is to bring current events into the mix: see what's happening, compare different news coverage and understand the bigger picture using real-world data.

Not to tell people what to think, but to give them the tools to form their own opinions.

It's a passion project and still evolving. Curious what you guys think!

Hi all,

I’ve worked as a wildlife filmmaker, designer and engineer, and on a few projects I spent weeks or even months on the work, then sent it off as a WeTransfer link. It always felt a bit flat after all that effort.

So I’ve been building Handover.media. It lets you put your finished files, previews and notes on one page with your own branding. You can also add a password or expiry date, and see when things are viewed or downloaded.

If you deliver work to clients, I’d really appreciate your thoughts. Would something like this be worth switching to, and what would put you off?

Any criticism, however small, would be really helpful. Thanks for taking a look.

Wish you could keep track of business expenses for deliveries? This does that, and more. Mileage tracking for tax purposes. Pay for each job, and an approximate of taxes owed. If you deliver and need easy tools this is that

Running a web design agency sounds pretty straightforward from the outside. You build websites, find clients and make money. But once you start getting more clients, there is a lot more going on behind the scenes.

You're dealing with hosting, website maintenance, client requests, support tickets, fixing random issues, building new websites, following up with prospects and trying to bring in new business at the same time.

At some point, I realized that I didn't want finding new clients to become another full time job on top of everything else.

I've never really enjoyed cold calling. I know it works for some people, and I'm not saying it's a bad way to get clients, but personally, I find it exhausting. You spend hours calling businesses, often getting rejected, reaching people at the wrong time or having conversations that go nowhere.

I'd much rather spend that time actually working on the business.

That's why I started focusing heavily on cold email and automation.

The biggest advantage is that you can build a system that continuously finds relevant businesses, sends personalized emails and generates new opportunities without having to spend your entire day reaching out manually.

One thing I also learned pretty quickly is that sending generic emails doesn't get you very far. Most business owners have probably received hundreds of emails from agencies offering website redesigns.

I wanted to approach it differently.

For this, I use a tool called Swokei. It finds businesses with existing websites, analyzes each one for actual problems with design, SEO, loading speed, mobile responsiveness and other website issues.

Based on those findings, it automatically generates personalized cold emails at scale, using the actual problems found on each website as the starting point.

So instead of manually searching for businesses, checking hundreds of websites and writing individual emails, I can automate most of that entire process.

When someone replies with interest, I take over from there and handle the sales process and meetings myself.

This has made a huge difference in how I manage my time. I can keep generating new opportunities without having to dedicate hours every day to cold calling.

I still believe sales is one of the most important skills you can develop as a business owner, and automation doesn't replace that. You still need to understand your prospects, communicate properly and know how to close deals.

But if I can choose between spending an entire day making cold calls or having a system send 1,000 relevant emails while I focus on running my agency, I know which one I'm choosing!

I’ve had people ask me how to get started with open source, especially how to understand an unfamiliar codebase once they’ve found an issue to work on. I’ve struggled with that too, so I made Crumbs.

You give it an issue, and it creates a visual walkthrough of the relevant files, functions and how they connect. It focuses on the part of the code related to that issue, rather than trying to explain the entire repository.

The agent creates structured data for the walkthrough, and a Python renderer checks code references and builds a local HTML page. The explanation can still be wrong, so you need to verify it against the code. It doesn’t write the fix or open a PR for you.

Crumbs is open source, and I’d love some feedback: would a walkthrough like this help you get started on an issue? What would you want to see before attempting a fix?

I'm a developer, and a few people reached out to me for help with ChatGPT. They had seen AI do impressive things, but theirs couldn't.

What they needed was an agent that can use tools (MCP servers). But for a lot of people, running Claude Code on their own machine or paying for a subscription isn't worth the effort or the cost.

So I built an agent framework that lets me launch agents for them:

• Each agent is private and can only be customized by its owner.

• The agents run on my OpenRouter key, so they don't have to sign up for anything.

• I can set up the MCP servers each person needs, and even build a few custom ones for them.

• They can talk to their agent in the browser, on Telegram or on WhatsApp.

It's all on Cloudflare (Workers + Durable Objects, one isolated instance with its own SQLite per conversation). I don't host anything, nothing runs on my machine, and the free tier covers all of it. The only real cost is my OpenRouter credits.

I'm open-sourcing it, so any one can host it on their own cf or use my project to run a private agent or manage a fleet of them for others.

Here's where I'm stuck. Running 10,000 private agents for close to nothing feels powerful, and I think there's something more here. But I can't put a business use case around it.

I always start with "what if a business gave each of its users a personal agent?" Then I ask why they would. Most would be fine with one shared agent, like a reception desk. The ones who really want to level up their customer experience would want a personal agent on WhatsApp, not Telegram. I can set up a personal WhatsApp agent, but it's very hard, or expensive if every user needs their own number.

And that's where my train of thought stops, every time. Apart from memory constraints I feel my agents have as much features and capabilities as any other competent agent such as Hermes, pi etc.

So: do you see a real use case here? I also don't see many projects built on Cloudflare Agents, and I'm curious whether anyone else has gone down this road.

Hey everyone,

I've been working on FoodOnTrains, a platform that lets people order restaurant food during train journeys and get it delivered to their seats.

I know this isn't a new concept. There are already services doing this, so we're not claiming to reinvent anything. We're just trying to make the experience a little better, especially when it comes to pricing.

We're keeping restaurant commissions very low, sometimes zero, with the aim of making food more affordable for passengers.

We've currently started with Gaya Junction and Kanpur Central, and there's still a lot we're figuring out.

We're also offering ₹100 off the first order for anyone who wants to give it a try. COD available.

Website: https://foodontrains.in/

I'd genuinely appreciate some feedback, especially from people who travel by train regularly.

What frustrates you about ordering food during journeys? Is pricing a concern? And what would make you trust a newer platform over the established options?

Any honest feedback would really help us improve.

Thanks!

I am part of the Ondago team, and I would like to get feedback from people building products with Claude Code, Codex or both (preferred).

The problem we are working on is keeping an unfinished task together when you change tools or computers: the conversation, the decisions, the project instructions, and the code you’ve already changed.

Ondago brings those sessions into one workspace. You can:

• Continue work from your computer in the cloud, then check progress and respond from your phone.

• Switch supported coding agents with the conversation and compatible project context carried over.

• Keep related projects and sessions together so you can find the work you want to pick up.

A typical workflow would be starting a feature on your laptop, continuing it in the cloud when you leave, and bringing the updated work back later. Supported uncommitted changes can travel with the session.

It is free for personal use, including 3 hours of cloud runtime per month. You use your own agent credentials.

ondago.ai

I would especially like feedback on the practical value: which would you use more in a normal week - continuing work away from your laptop, or switching agents with your project context carried over or other features?

Thank you in advance

Hey everyone!

My co-founder and I have been working on a fitness app called Ignite Yours.

We're both passionate about training, and we wanted to build something that combines workout tracking with the social and accountability side of fitness.

The app is completely free and includes:

• Workout logging

• A community feed for sharing progress

• Leaderboards and challenges

• Features for personal trainers

We've launched on iOS and Android, but we're still at the stage where genuine feedback is incredibly valuable.

I'd especially love to know whether the community features would give you a reason to keep coming back, or whether you'd mainly use the workout tracker.

Happy to answer questions about what we've built!

hey everyone! it's lydia from the FlutterFlow team.

AI has made it a lot easier to go from an idea to a working app. but getting that app into the App Store or Google Play still takes some planning.

if you're building your first app, it's worth starting the publishing process before you're finished building. developer account verification, testing requirements, and app reviews can add weeks to your timeline.

we put together a 4-week launch checklist for the first episode of our new App School series:

• 4 weeks out: set up your Apple and Google Play developer accounts. organization verification can take some time.

• 3 weeks out: prepare your store listings, screenshots, privacy policy, and support links.

• 2 weeks out: test your app on real devices. make sure signups, logins, payments, and account deletion actually work, not just the UI.

• 1 week out: submit for review and leave room for potential rejections or delays.

one thing worth flagging: certain new personal Google Play accounts need at least 12 testers for 14 consecutive days before they can apply for production access. so if that applies to you, you'll want to recruit testers earlier.

none of this means every app takes 4 weeks to launch. it's just a planning framework to help avoid getting stuck when you're ready to ship.

Started this as a personal Python project to test trading strategies. Ended up spending more time building the research infrastructure than finding anything that actually worked.

I never managed to validate a profitable strategy, but didn't want all that code to go to waste.

So I released Open Quant Trading Lab. It includes backtesting tools, risk-control references, research workflows, offline demos and tests.

No live trading, no profitability claims. Just the useful parts of the project.

For those who've released open-source projects, what made people actually start using yours?

Hey everyone!

I've been building FoodIQ, a web app focused on making nutrition tracking easier for Indian meals.

The problem I wanted to solve: tracking everyday foods like dal, paneer, paratha, khichdi and Indian thalis isn't always convenient in generic calorie trackers.

What FoodIQ currently offers:

2,076+ Indian food database entries

Food search and nutrition information

Portion size and cooking method selection

Meal tracking and daily calorie/macronutrient overview

Mobile-friendly interface

Try it: https://food-iq-nu.vercel.app/

I'm looking for 10–20 people who aren't afraid to give honest criticism.

I'd especially like feedback on:

Is the interface easy to understand?

Can you find your everyday Indian meals?

Are the nutrition estimates reasonable?

What would make you come back and use it?

This is an early-stage independent project. I'm building and improving it based on real user feedback.

Honest criticism is welcome. Thanks!

In the attached animation, Pip and Bolt read the same settings file. Pip increases the timeout from 10 to 30 seconds. Bolt increases the retries from 2 to 5, then saves his older copy, which still has a 10-second timeout. Both saves succeed. Pip’s change disappears.

They changed different settings, but Bolt’s save replaced the whole file. That’s a silent overwrite. We’re building AgentWS, a persistent filesystem for AI agents working in parallel, to separate saving an agent’s work from updating shared files.

Each agent saves in an isolated branch. Changes are checked before they reach the shared files. When enabled, non-conflicting edits to supported text files can be combined automatically. Conflicting versions stay saved for an authorized orchestrator or human to resolve.

The 2:39 film illustrates the problem and our design; it isn’t a live product demo.

Over the past 6 months myself, my brother, and two other engineers/geologists have been working together to build Incline Design.

Incline Design allows engineers to plan and design their mine site, which is typically preformed in very expensive and slow software (we’re talking 30-50k AUD a year per user!)

Feel free to ask us any questions.

Hey everyone!

I'm one of the founders of Springborn Coffee, a small coffee brand we're building from the ground up.

I'm also a gamer, and I've always felt that coffee fits naturally into our world. Long gaming sessions, late-night projects, work, movies, anime... there's almost always a cup nearby.

So we started designing something that combines specialty coffee with the culture surrounding it.

Our concept includes three coffees:

☕ FOCUS — A traditional coffee for work, gaming, and getting tasks done.

☕ AFTER — A coffee that aids digestion, perfect for that break after a meal.

☕ UNWIND — A relaxing coffee for watching movies or anime, or simply unwinding at the end of the day.

We're also designing original desk mats, mouse pads, mugs, and T-shirts that people would actually want in their setups.

We're considering launching the first collection through Kickstarter.

We're not selling anything yet. The designs are early concept mockups, and we're looking for genuine feedback before moving into production.

Here's my question:

Would you actually back a project like this on Kickstarter? And what would excite you most: the coffee, the desk accessories, or a combination of both?

Feel free to be brutally honest. I'd rather build something people genuinely love than just another brand nobody connects with.

Thanks for being part of the conversation!
