I made ChessExplain because engines tell you the best move but never why it's best. Mine pairs in-browser Stockfish (for the actual lines and eval) with an LLM that explains those lines at the level you pick. Beginner gets "your knight has no safe squares," advanced gets the full positional reasoning. You can also ask it follow-up questions about any position.

Free with no card (~10 AI analyses/month, unlimited engine eval, 100k+ puzzles). Import a Lichess game, paste a PGN/FEN, or set up a position. Would love to hear what you think: https://chessexplain.com

PLAY IN REDDIT : r/morphychess
I built a small chess puzzle game with one twist:

Every time you capture a piece, you become that piece.

Your movement changes after every capture, so every puzzle is about planning not just your next move, but what you’ll become next.

I’m calling it Morphy Chess. It’s still an early side project, but I’d love to hear what you think about the core mechanic.

Feedback, ideas, and criticism are all welcome.

I’m 14 and built a full-stack, privacy-first chess platform from scratch (Beta). Would love some feedback!

Hey r/chess**,**

I wanted to share a passion project I’ve been working on over the last few weeks. I’m a 14-year-old developer, and I decided to challenge myself by building a complete, full-stack chess platform completely from scratch. It’s currently live in beta, built and hosted using Bolt.new, and I’m looking to get some feedback from actual players to help me improve it.

🛠️ The Philosophy Behind the Site

There are already massive chess platforms out there, but my main goal with this project wasn't to compete with them—it was to see if I could build a secure, lightweight alternative that respects the user.

Personally, I am incredibly focused on digital privacy and clean network traffic. A lot of modern websites are bloated with dozens of third-party tracking scripts, invasive analytics, and heavy backgrounds that slow things down. I wanted to build a chess environment that is completely transparent. The backend architecture is built to handle user data securely, storing only what is absolutely necessary to make the app work (like your account and your games) without any hidden tracking.

🚀 What’s Packed Into the Beta Right Now

I’ve focused heavily on getting the core full-stack infrastructure solid before adding too much visual fluff. Here is what is fully functional today:

 Secure Authentication System: A clean login and signup flow. Your credentials and session data are handled safely.

 Responsive Playable Interface: A lightweight, smooth chess board designed to handle piece manipulation cleanly without lag.

 Match History Tracking: Every game you complete is saved to the database under your profile, allowing you to go back and keep a record of your progress.

 Game Review System: An analytical tool built in so you can step back through your board states post-match and review your moves.

🚧 What’s Coming Next (Under Construction)

The biggest challenge I'm tackling right now is Multiplayer. The UI components are there, but I am currently ironing out the real-time networking and matchmaking backend to make sure it's fast and stable. Right now, it's a work in progress, but full P2P/Server-side multiplayer matchmaking is the next major milestone.

💬 I Need Your Feedback!

Because the site is in active beta development, player feedback is everything. I’d love for a few people to create an account, test the board, and tell me honestly:

1. The Feel: How does the piece movement and board responsiveness feel compared to what you're used to?

2. The Tools: Is the Game Review UI intuitive? Did you run into any weird glitches when analyzing a finished game?

3. The Flow: Did you experience any friction or bugs during the login or signup process?

4. Features: What kind of unique tools or features would make you want to use a lightweight, privacy-respecting site like this?

Thanks a ton to anyone who takes a few minutes to look at the code's output and move some pieces around. I'll be in the comments responding to feedback and taking notes for the next update cycle!

It’s completely free, no sign-up, and everything runs locally on your hardware.

It’s called Chess Review. You open one of your games, click the icon/button, and it gives you a full review that on average lands within about 3 accuracy points of Chess.com’s accuracy scoring, but often much closer. It’ll never match 100% as the underlying algorithm is proprietary, but it gets close enough to feel familiar.

Happy to hear feedback. It’s v1 so there’s plenty of room to improve. If there’s interest I’ll look at a Firefox version too.

What I got working today:

→ A board that prints correctly to the terminal

→ All 32 pieces in their starting positions

→ Full TDD : Test Driven Development - every feature has a failing test before any code is written.

We simulated a small case with my daughter at home, where she was warned with her own recorded voice about illegal moves by my phone. Fun starts at 18th second of the video.

AggroChess v2.0.0 is officially out, adding a massive +200 Elo playing strength boost while keeping its signature Mikhail Tal-style aggressive and sacrificial playstyle: https://github.com/PhelRin/AggroChess/releases/tag/V2

Also a lot of people were very weary last time about the code not being open source, so I open sourced it. I know its stronger than the previous version. Still fun to play against, I'd say its more around the 2600 range on average now, but I'm not sure yet. I'd say in between 2400-2600

I've been working on a computer vision project that turns a phone into a companion for over-the-board chess, and I'd love some feedback from the community.

The idea is simple: point your phone at the board (a tripod helps, but isn't required), and the app detects the pieces in real time, tracks the game, and can provide useful assistance like:

• Recording moves automatically.
• Running a chess clock.
• Warning if a king is left in check (surprisingly common in junior tournaments).
• Announcing checks and other events.

Everything runs on-device, so no internet is required.

The app is free, and you can find the iOS and Android download links here:
https://magicalchess.app/

I'm especially interested in feedback on accuracy and usability.

Current challenges:

• Camera dead spots and occlusions.
• Occasional hallucinated piece detections.
• I'm trying to use the previous game state to recover from these errors, but there's still room for improvement.
• Pawn promotions aren't implemented yet.

I'd really appreciate any feedback, bug reports, or feature suggestions. Thanks!

Entering a chess position manually can be tedious, and smart chess boards that automate the process are often quite expensive.

To explore a more accessible alternative, I've been building a free mobile app that uses a phone camera to recognize positions from a physical chessboard. It can automatically run the chess clock, detect illegal moves, record notation, and provide a growing set of tools designed to make over-the-board chess more convenient.

One of the latest additions is a snapshot feature that works much like taking a regular photo, making it easier to use without a tripod or dedicated setup.

Short demo:

The project is still a work in progress, and I'm actively improving detection accuracy and handling edge cases. If you'd like to test it and provide feedback, I'd love to hear your thoughts.
