How it works

No surprises

  • What counts as a message

    One message a person sends to any of your agents — through the widget, the API, WhatsApp, voice, or your own Playground tests. Approving an action an agent asked to confirm does not count.

  • Starter messages

    On Free, your agents answer on our model for their first 50 messages, so you see it work before setting anything up. After that, add a key from any provider in Model Hub.

  • When you reach a limit

    Workspace owners get a heads-up in the console at 80%, and an email too at 100%. At the monthly message limit, agents pause until the 1st; everything else keeps working.

  • Changing plans

    Upgrades take effect within a minute. If you move to a smaller plan, nothing you built is deleted — you just can’t add more beyond the new limits.

FAQ

Questions, answered

Do I need a credit card to start?

No. Sign up, name your workspace and build your first agent on the Free plan. No card, no trial clock.

Which model providers can I use?

Add keys for Anthropic, OpenAI, OpenRouter, Sarvam or Ollama in Model Hub, and choose the model per agent. On Pro and above your agents can also run on our keys.

Do Playground test messages count toward my limit?

Yes — every message to an agent counts, whichever channel it comes from. The console shows how many you have left right under the Playground composer.

What happens when I hit the monthly message limit?

Your agents stop answering until your allowance resets on the 1st of the month (UTC), and visitors see a short, neutral message. Upgrade at any point to resume straight away.

What happens to my agents if I downgrade?

Nothing is deleted. Agents, knowledge bases and channels you already have keep running; you can’t create more until you’re back within the new plan’s limits.

How do I pay for Pro or Premium?

Self-serve checkout is on its way. Until then, talk to us and we’ll move your workspace to the plan you choose.

Is Achilles built for regulated teams?

Yes. Every plan encrypts data with workspace-isolated keys and records an audit trail. Premium adds signed audit export and a tamper-evident trail; Enterprise adds customer-managed keys and dual approval.
