letronna.si · the short address of letronna.ai

Your agent, with its own cloud and wallet.

Letronna is an open-source AI agent, built in Rust. It works on your computer and in your terminal with any model or account, hosts what it builds at a live link, and pays for the APIs it needs. macOS, Linux and Windows. Everything is at letronna.ai.

In short

Runs on
macOS 13 or later, Windows 11 and Linux (glibc 2.31 or later). A desktop app and a terminal app that share the same sessions and memory, each one native binary.
Models
Hosted models on a Letronna account, your own keys (OpenAI, Anthropic, Gemini, xAI, OpenRouter), local models through Ollama or llama.cpp, and any OpenAI-compatible gateway of your own. When one account hits its limit it falls back to the next.
Memory
Plain-text files under ~/.letronna, on your disk. Nothing leaves the machine unless you connect a hosted model.
Cloud
Runs a task on Letronna's servers from a prompt, a repository or a folder on your computer, and keeps web apps and bots (Discord, Telegram, schedulers) online around the clock.
Wallet
The agent pays for the APIs it needs itself, so a task is not stopped by a missing key.
Tools
Files, shell commands, web search and fetch, a browser, subagents, schedules and MCP servers. Less used tools are loaded on demand to keep each request small.
Price
Free with your own keys. Pro is $20 a month, with $20 of hosted credit included. Team is $18 a seat a month, one credit pool for everyone.
License
The agent runtime is Apache-2.0 on GitHub. The hosted model pool and cloud deploy are the paid parts.
