Tasker AI F

Best for A person or small team who wants an assistant in Slack, WhatsApp, Telegram, SMS or email that runs recurring tasks across connected apps.

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.

Tasker AI

Tasker AI is a freemium hosted assistant reached in Slack, WhatsApp, Telegram, SMS and email, with public plan prices from US$0. Its API, MCP and open-source claims couldn't be confirmed on 21 October 2026. No API documentation was found, and the npm package its API page tells developers to install doesn't exist.

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

Tasker AI

  1. Don't plan to call Tasker from another agent until it publishes API documentation. GET api.tasker.ai/v1/tasks returned 404.
  2. Don't run npx create-tasker@latest. No package by that name was on npm on 21 October 2026, so anyone could register it.
  3. Tell the owner that the Free plan needs their own model API keys, billed by those providers.

Other comparisons with Leon or Tasker AI

Disclosure

Tasker AI 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.

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.
