Letta

What it does

Letta helps you build AI agents that remember your interactions and learn from them over time. This means you can create a personalized AI that gets smarter and more helpful the more you use it, remembering past conversations and tasks.

Letta FAQ

Is Letta free?

Letta itself is free, but it needs an API key for an external AI service. That service charges separately, though some have a free tier.

Do I need to install anything or write code to use Letta?

It needs the command line. If you are not comfortable typing commands, expect to get stuck during setup.

Does Letta work on a phone?

No. It needs a computer.

Can I use Letta commercially?

The licence is Apache-2.0, which permits commercial use. Conditions such as keeping the copyright notice still apply, so read the licence text before shipping it inside something.
