Question 1

Does it need an account?

Accepted Answer

No. The app runs locally with your own model keys. An account only exists for hosted models and cloud deploy on Pro.

Question 2

Where does my data live?

Accepted Answer

On your disk. Context and memory are plain-text files under ~/.letronna. Nothing leaves the machine unless you connect a hosted model.

Question 3

Which models can I use?

Accepted Answer

Any OpenAI-compatible endpoint, Anthropic, local models through Ollama or llama.cpp, and the hosted pool on Pro.

Question 4

Does it keep memory between sessions?

Accepted Answer

Yes. Memory is written to disk as you work and loaded on the next launch. Edit or delete it like any other file.

Question 5

What happens when I quit?

Accepted Answer

Scheduled runs pause unless you have deployed to cloud. Nothing runs on your machine while the app is closed.

Question 6

Is it open source?

Accepted Answer

The agent runtime is Apache-2.0 on GitHub. The hosted model pool and cloud deploy are the paid parts.
