Verdicts

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.

OpenDuet

Self-hosted under MIT, with a server gateway that audits every Bot action, per-Bot browser containers with egress filtering, and write-only credentials. Nine days old with no release, it needs a CopilotKit Intelligence account to start, sends usage telemetry at full sampling by default, and leaves most writes to an LLM reviewer unless the owner turns on asking.

Before you call either

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.

OpenDuet

  1. Follow the README's Quick start (bun install, bash scripts/start.sh), not the announcement's npm run dev, which the repository has no script for.
  2. Run bun openbot/scripts/setup-learning.ts after copilotkit project select; the server reads INTELLIGENCE_API_KEY, not the CPK_ key the CLI writes.
  3. Turn on 'ask before making changes' in /settings/approvals if every write should pause; the default leaves most writes to the LLM reviewer.
  4. To bring your own agent, register it as a remote-ag-ui Bot in agents.yaml; its tool calls still pass through the gateway's policy and audit.
  5. Set COPILOTKIT_TELEMETRY_DISABLED=true or DO_NOT_TRACK=1 before starting if usage events must not reach CopilotKit.

Other comparisons with Boba or OpenDuet

Disclosure

Boba competes with LocalGhost, which Anchor Terminal's founder builds. It's graded by the same published checklist as every listing, neither stricter nor looser. Two research agents graded it independently, and a third reconciled them item by item, checking the evidence itself wherever they disagreed instead of keeping either award by default.

Machine-readable

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
