Ahead on: - Reliability, 32 against 15 - Schema & documentation, 33 against 0 - Agent ergonomics, 57 against 0 - Security & auth, 34 against 0 - Payments & pricing, 60 against 10 - Transparency & trust, 60 against 47 Also in its favour: - No key needed to call it - Free to start without a card - Open source Watch for: No tagged release of the core since 1.0.0-beta.8 on 1 May 2023. The 2.0 Developer Preview is installed by cloning the develop branch ### Tomo (F) Good for: People who want accountability, check-ins and reminders by text, including in group chats. Ahead on: - Maintenance & community, 54 against 15 Watch for: No API, MCP server or A2A endpoint for an outside agent. ## Score by category | Category | Weight | Leon | Tomo | Edge | | --- | --- | --- | --- | --- | | Reliability | 16% (20 this run) | 32 | 15 | Leon +17 | | Performance | 10%, pending | pending | pending | not scored in this run | | Schema & documentation | 13% (16.2 this run) | 33 | 0 | Leon +33 | | Agent ergonomics | 13% (16.2 this run) | 57 | 0 | Leon +57 | | Security & auth | 14% (17.5 this run) | 34 | 0 | Leon +34 | | Payments & pricing | 10% (12.5 this run) | 60 | 10 | Leon +50 | | Task success | 10%, pending | pending | pending | not scored in this run | | Maintenance & community | 7% (8.8 this run) | 15 | 54 | Tomo +39 | | Transparency & trust | 7% (8.8 this run) | 60 | 47 | Leon +13 | | Negative events | ≤15 | 0 | 0 | | | **Total** | | **41 · E** | **13.1 · F** | | ## Facts side by side | Fact | Leon | Tomo | | --- | --- | --- | | Kind | Agent harness | Platform | | Vendor | Louis Grenard (Leon AI) | Mapo Labs, Inc. | | Hosted endpoint | no (local only) | no (local only) | | Transports | | | | Auth | None | OAuth or key | | Pricing | Free | Paid | | x402 | no | no | | Licence | MIT | Closed service under Tomo's Terms of Service (Mapo Labs, Inc., last updated 24 September 2026). | | Read-only variant documented | no | no | | llms.txt | no | no | | Last release | 2023-05-01 | 2026-09-29 | | Terms last updated | no document linked | | | Privacy policy last updated | no document linked | | | Customer content may train models | | | | Terms restrict automated access | | | | Terms restrict benchmarking | | | | Terms or service can change without notice | | | | Arbitration or class-action waiver | | | | Popularity | 18k stars | none | ## Verdicts **Leon.** Connected-app credentials are encrypted per profile and the Gmail connection is read-only. The 2.0 Developer Preview has no tagged release, runs tools and a 30-minute proactive pulse with no approval step, listens on every network interface with client authentication off, and sends telemetry by default. **Tomo.** Tomo is a hosted personal AI over iMessage and an iOS app, centred on goals, check-ins and reminders, with regular iOS releases since April 2026. No outside agent can call it, there's no free plan, and no status page, security contact or subprocessor list was found. ## Before you call either ### Leon 1. Clone the develop branch for 2.0. `npm install --global @leon-ai/cli` and docs.getleon.ai install and describe the legacy 1.0 betas 2. Set `client_interface.auth.enabled: true` and a `LEON_PROFILE_TOKEN` before the machine joins a shared network. The server binds 0.0.0.0 3. Set `telemetry_enabled: false` and `runtime.pulse_enabled: false` in the profile `config.yml` for an unattended or private run 4. Use `availability.tools.allowed` to limit tools. Shell, file writes, computer use and browser control are otherwise available to the agent with no approval prompt 5. Back up `LEON_CONNECTIONS_ENCRYPTION_KEY` from the profile `.env`. Without it the stored connections cannot be read ### Tomo 1. Don't plan to call Tomo from another agent. It answers only the owner's iMessage, group chats it's added to and the iOS app. 2. Tell the owner that adding Tomo to a group chat applies its terms to every participant. ## Questions ### Which is better for AI agents, Leon or Tomo?

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.
