iiinova — where your digital self keeps evolving

3/ Model Agnostic + BYOK Connect your existing ChatGPT subscription or LLM API keys. Port your agent (including all its configuration and state) to the latest model release.

2/ Works where you work Bring your agent to where your team works. Chat with the same agent on Discord, Slack, Telegram, or through custom channels - just like you would a human coworker.

1/ Learning & memory Each agent becomes unique through its own experience, and what you & your team teach it. As you work with your Letta Agent, it will rewrite its skills, prompts, and other reference files (e.g. a wiki) over time.

Letta Agent is the easiest way to add persistent, digital coworkers to your team. Each agent: - is teachable and customizable - never forgets - works with your whole team (not just you) - runs locally & on remote machines Available on MacOS/Linux/Windows
