Privacy
Some privacy controls exist, but vendor-hosted infrastructure still handles a meaningful share of the data flow.
Most usage data runs through a managed vendor environment, so privacy control is limited.

- 1M token context window
Manus AI pros

- Limited persistent memory — session context only
Manus AI cons
- Premium pricing ($79+/month)
- Closed source — no self-hosting option
