As answered by people managing Mimmo Engine and GDevelop.
Mimmo Engine's answer
The AI runs on your own machine. Mimmo downloads a local model on first launch and generates dialogue, scenes and character sprites without sending your story to anyone's server, so there is no per-token bill and no account needed to start writing.
The rest of the editor is drag and drop: over twenty block types covering dialogue, branching choices, variables, inventory, minigames and phone conversations, with a live preview that plays the game while you build it. Projects are plain JSON files, so your work is never trapped in a proprietary format.
Mimmo Engine's answer
Ren'Py is the standard and it is excellent, but using it means writing Python. Plenty of writers stop right there. TyranoBuilder and Visual Novel Maker remove the code and hand you a paid licence instead, with AI that is either absent or bolted on through a cloud subscription.
Mimmo removes the code and runs its AI on your own hardware, with no API key and no per-token bill. The free plan is a working editor, not a trial: unlimited projects, the full block system, and story, scene and sprite generation included. Premium at 19 EUR per month is what you pay when you are ready to distribute and to build bigger, and it can be cancelled at any time.
Mimmo Engine's answer
Writers and artists who have a story to tell and no intention of learning to program. Solo creators and small teams building visual novels, interactive fiction and narrative games, often alongside another job.
A good share of them tried Ren'Py first, ran into the scripting, and put the project down. Mimmo is built for the moment right after that.
Mimmo Engine's answer
Making a visual novel used to mean picking a side: learn to script, or pay for a closed tool that decides what you are allowed to build. Neither felt right for someone whose actual skill is writing or drawing.
Mimmo was built to remove that choice. The whole editor is visual, the AI runs on the creator's own hardware instead of a metered API, and the free version is the finished product rather than a trial of it. It is developed in Italy and ships for Windows, with macOS and Linux in progress.
Mimmo Engine's answer
The editor is React and TypeScript, bundled with Vite and shipped as a desktop app through Electron. State and undo history run on Zustand.
The local AI is llama.cpp with quantised open models, downloaded on first launch and stored on the user's machine, which is what keeps generation free and offline. The games themselves run on a custom runtime, and projects are stored as readable JSON so nothing depends on a proprietary binary format.
