Otto uses prepaid workspace credits. Each review or workflow is charged for the work it actually performed, based on verified usage.

​
Getting started

When you create a workspace, Otto asks for a card. It verifies the card with Stripe (no charge) and adds a $10 welcome credit so your first reviews can run. Auto-reload is on by default, and you can change it before you save the card.

​
Adding funds

  1. Go to Settings → Billing.
  2. Click Add Funds.
  3. Choose a preset amount or enter your own.
  4. Pay through Stripe.
The Add Funds dialog Unused credits never expire.

​
How charges work

  • Only verified usage is billed. Estimated prices are shown for previews only and are never billed.
  • Review charges are grouped by pull request, so you can see what each PR cost.
  • Depth affects cost. Deeper review depths cost more; use otto.yml to spend depth where it matters and ignore files that don’t need review.
  • Fractional cents are kept and carried into later charges instead of rounding each request up.
  • Unverified usage stays pending until it can be reconciled. Otto never guesses a cost.

​
What you’re not charged for

  • Workflow attempts that fail terminally, and failed recovery attempts. A failed attempt stays waived even if a later retry succeeds.
  • Skipped reviews and PRs too large to review automatically.
Recoverable tool errors and negative review findings aren’t failures; a review that requests changes is a successful review. If you cancel a workflow, usage already consumed before the cancellation is billed.

​
When automation pauses

Otto pauses automation for a workspace when:
  • It runs out of credits, or
  • 3 workflow attempts in a row fail terminally, or
  • Failed attempts absorb $5.00 of cost within 24 hours.
Successful work resets the failure streak. Add funds to resume after running out of credits; contact support if automation is paused for failures.

Viewing usage

Settings → Billing shows usage by date, model, workflow, and run, including token details when available and each record’s billing label. See Usage.
