Message, clock, diagram and player card enrich the screen you share.
Each overlay is a separate system window — movable between your screens and always on top of the call.
1,000 players and 140 tournaments — every World Championship and Candidates cycle. Showing a Ding Liren game? Project his card on screen to set the context or enrich the session. The database is local: it doesn't slow your connection, and never queries an AI live.
62 diagrams already built into ChessHUD. Lichess-style arrows, ChessBase-style coloured squares, and a position editor. No more switching windows to show your student what the Carlsbad structure looks like!
The instruction, the topic being studied, a hint toward the solution. The library lets you save your messages so you don't have to retype everything each time. No more opening a text editor on the side!
Countdown or count-up timer with a progress bar. Adjustable added time and presets. No more opening the Windows clock!
ChessHUD is built in my spare time and will stay free. If you like it, you can support its development.

HUD stands for Head-Up Display. Borrowed from aviation and video games, the term means information laid over the screen without hiding what matters. ChessHUD brings that idea to chess: your notes appear on top of the screen you share, without ever covering the board.
Yes — free, and forever. No ads, no subscription, no tracking, no account to create. If the app is useful to you, you can support its development on Ko-fi, but nothing is ever locked or paid.
ChessHUD is a desktop app for Windows. It works alongside any video-call tool (Google Meet, Zoom, Teams…) and shows its overlays on the screen you share, whether you teach online or in person.
The app isn't code-signed yet, so on first launch Windows shows a SmartScreen prompt. Click More info, then Run anyway. It's safe — the message only appears because the publisher isn't registered yet.
Seven: French, English, Spanish, German, Russian, Italian and Portuguese. Each download is a single language — pick yours from the list in the download section.
Every year, a new version of ChessHUD is released for free — with the app's improvements and the updated database (players, tournaments and recent results). To install it, just download the latest version from this page. Current version: V1.0.
Yes, entirely! And exclusively with Claude (the Opus and Fable models). But it took several months of back-and-forth and iteration — work that wouldn't have been possible without my experience teaching chess online, and my experience with AI in general.
Bugs, ideas, comments from your students — it all helps make ChessHUD better.
