# Plans and billing

> The three plan axes, what each tier unlocks, and how plan changes take effect.

Mavel plans differ on three independent axes: how many prompts you can track,
how many AI engines you can enable per project, and how many projects you can
run under one organization. Every plan tracks across all enabled surfaces
daily; you choose which engines to activate, subject to your plan's allowlist.

## The plans

| Plan       | Price     | Tracked prompts | Engines | Projects  |
| ---------- | --------- | --------------- | ------- | --------- |
| Starter    | €89 / mo  | 50              | 3       | 1         |
| Pro        | €249 / mo | 150             | 6       | 3         |
| Growth     | €499 / mo | 400             | 8 (all) | 10        |
| Enterprise | Custom    | Unlimited       | All     | Unlimited |

Annual billing is available at a discounted monthly rate. Prices shown are EUR;
USD pricing is also available. See [mavel.ai/pricing](https://mavel.ai/pricing/)
for current prices. That page is the source of truth.

### What the axes mean

**Tracked prompts**: the number of active prompts across all your projects
combined. A prompt that is drafted but not yet activated does not count against
the limit. If you reach your prompt cap, you can deactivate existing prompts to
free up headroom, or upgrade.

**Engines**: the AI surfaces Mavel runs your prompts against. Starter includes
ChatGPT, Google AI Overviews, and Claude. Pro adds Perplexity, Gemini, and
Microsoft Copilot (six engines total). Growth enables all eight surfaces:
ChatGPT, Perplexity, Gemini, Claude, Google AI Overviews, Google AI Mode,
Microsoft Copilot, and Grok. See [Surfaces](/setup/surfaces) for detail on how
each channel works.

**Projects**: each project is an independent tracked brand with its own prompt
set, competitor list, and results. Starter supports one project. Agencies
typically use Growth or Enterprise to run one project per client.

### Agency plans

Mavel offers Agency plans for multi-client setups. Contact sales to discuss
pricing and structure; see [mavel.ai/pricing](https://mavel.ai/pricing/) for
details.

### Enterprise

Enterprise includes unlimited prompts, projects, and all eight engines, plus
custom onboarding and volume pricing. Contact sales from the billing page or at
[mavel.ai/pricing](https://mavel.ai/pricing/).

## API and MCP access

REST API and MCP server access require the **Growth plan or above**. On lower
plans, the API Keys page shows an upgrade prompt instead of key management. See
[API keys](/account/api-keys) and [MCP introduction](/mcp/introduction) for
details on what the API and MCP server provide.

## How plan changes work

<Steps>
  <Step title="Go to Billing">
    Open the billing page from the account menu. Your current plan is
    highlighted.
  </Step>

  <Step title="Select a plan">
    Click the plan you want. Upgrades and downgrades both route through the
    same checkout flow.
  </Step>

  <Step title="Confirm">
    Complete the checkout. The plan change applies to your organization
    immediately.
  </Step>
</Steps>

**On upgrade:** your prompt cap and engine allowlist expand right away. The
next daily run will use the new engine set.

**On downgrade:** your prompt count is clamped to the new plan's limit: the
newest active prompts beyond the cap move back to suggested status, and your
earliest-created prompts stay active. Engines not
included in the new plan are disabled for the next run. Historical answers for
all prompts and engines remain visible; nothing is deleted.

<Note>
  The prompt limit is org-wide, not per project. If you have three projects on
  a Pro plan, the 150-prompt cap covers all three combined.
