Letta pros
- Open source with transparent code and flexible deployment options.

- Good memory and persistence support for ongoing conversations or tasks.
ai.com cons
- Closed-source offering, so portability and vendor transparency are limited.
- Security posture is weak for high-trust or regulated workflows.
- Privacy controls are limited compared to self-hosted alternatives.
Letta cons
- Lower autonomy — designed more as a platform than an out-of-box assistant
- Setup requires understanding memory architecture concepts
- Python-only — no native TypeScript/JavaScript implementation
ai.com gotchas
- Review the official docs before committing, because integration details can change faster than summary pages.
Letta gotchas
- You should expect ongoing hosting, uptime, and secret-management work if you deploy it for real users.
