About FivLet
The story behind the game.
What is FivLet?
FivLet is a free AI-powered word guessing game where every puzzle is uniquely generated — no two games are ever the same. Using Google's Gemini AI, FivLet creates both the secret 5-letter word and a custom clue just for you, in real time.
Unlike other word games that use a fixed daily puzzle, FivLet generates a brand new word and clue every time you play. You have 4 guesses and up to 2 hints to figure out the word. It sounds simple — it isn't always.
Why we built it
We wanted a word game that never got stale. Fixed daily puzzles are fun, but once you've played today's word, you're done. FivLet gives you an unlimited stream of unique puzzles, each with its own AI-crafted clue that makes you think differently about the word.
We also wanted something that worked beautifully on both web and Android — so FivLet lives at fiv-let.com and is also available as a free app on the Google Play Store.
The technology
FivLet is built on Google Firebase for authentication, data storage, and backend functions. Word clues are generated by Google Gemini, Google's large language model, via the Genkit AI framework. The Android app uses a native WebView to deliver the same experience on mobile.
Premium
FivLet is free to play with a daily limit of 5 games for signed-in users and 3 for guests. FivLet Premium removes the daily limit entirely and unlocks leaderboard access, so you can compete for the top spot against other players around the world.
Premium is available via Google Play on Android or via Stripe on the web. There's no long-term commitment — cancel any time.
