Talk to anyone you can imagine.
mi·do·na is a place to play out stories with characters you make, running on a model on your own machine or your own API key. Bring a character, not a config file; the engine handles the rest.
Private by default. Yours by design.
No account to start. No telemetry on your story. Nothing you write is ours to keep; it runs on the model you choose, and stays between you and it.
Runs where you want
Point mi·do·na at a model on your own computer and play fully offline. No cloud required; nothing leaves the room.
Prefer a hosted model? Bring your own key for any provider. We don't store, read, or train on what you send. Your traffic, not ours.
No account, nothing tracked
Start playing without signing up. No profile, no telemetry, nothing tied to who you are.
Stored on your device
Your characters, stories, and settings live on your device, not our servers. There's nothing on our side to lose, leak, or hand over.
Long stories that don't lose the plot.
Long sessions drift, forget, or blow the token budget. mi·do·na compacts the story as you play, so a scene stays coherent across dozens of turns even on a context as small as 8k. Three pieces do the work:
Core Memory
The moments you mark as unforgettable. Core Memory pins them into every prompt, no matter how far the story runs.
Current scene
A tight snapshot of where things stand right now, so the model stays oriented without re-reading the whole log.
Story so far
Everything older, distilled into a running synopsis, so the plot survives even after the raw turns scroll out of the window.
- 01Fought the lion at the gate.
- 02Found the treasure beneath it.
- 03Met the king who wants it back.
Let your character be a character.
Most formats bury the character under prompt scaffolding like system rules, jailbreaks, anti-derail hacks, and formatting. mi·do·na takes all of that off your plate so you can focus on one thing: making your character perfect.
Same result. You only write the character.
Coming from SillyTavern? Bring your v2 library. mi·do·na imports your cards and helps you convert them over. You perfect the character; the engine handles the rest.
Get started →Where it's headed.
mi·do·na is early and single-player today. Sharing your characters, following other creators, and snap-together scenes & lorebooks are on the way. For now, a great character is still just a file you can hand to a friend. See the full roadmap →
