When NOT to use letta
Constraint-first guidance from category fit and live maintenance signals - not marketing copy.
- If you are looking for a simple stateless AI solution without advanced memory capabilities, as letta is geared towards more complex stateful agent development.
- When your project's requirements involve strict limitations around data retention and privacy where even anonymized interaction logs might be considered sensitive.
