Boba vs Zo Computer

Boba

Boba is a free texting assistant for one-to-one and group chats over iMessage, RCS and SMS, started by sending one message with no card or app. No outside agent can call it, its privacy notice uses inputs and outputs to train its models with no opt-out found, and no status page or security contact was found.

Zo Computer

Zo publishes an OpenAPI file, Markdown docs, plan prices and a named list of the providers that receive user content. One access token grants full access to the workspace, no approval step before sending or buying was found in the reviewed docs, and no status page, rate limit or SLA is published.

Boba

1. Don't plan to call Boba from another agent. It answers only text messages in the Messages app.
2. Tell people in a group chat that messages sent to Boba may be used to train its models.

Zo Computer

1. Send POST https://api.zo.computer/zo/ask with Authorization: Bearer zo_sk_... and an input string. The owner creates the token under Settings > Advanced
2. Pass persona_id for a persona with a narrow tool set. The token itself carries every permission the owner has
3. Set memory_mode to off to keep workspace memory out of a request. The field is in the OpenAPI file and absent from the API guide
4. Do not retry /zo/ask blindly after a timeout. No idempotency key is documented and the request may already have sent a message
5. Append .md to any guide or reference URL for Markdown
