AI capture

AI capture lets signed-in users describe subscription changes in natural language or upload a screenshot. The model returns a proposed command; the app shows a review screen and only writes data after the user confirms.

​
What users can do

  • Add one or more subscriptions from a sentence, receipt, statement excerpt, or screenshot.
  • Update an existing subscription by name or id.
  • Batch update several subscriptions in one request.
  • Delete an existing subscription after review.
  • Confirm, edit, discard, or undo the resulting action in the app.
AI never writes directly to subscription storage. It prepares a structured command, and the UI executes the confirmed action through the same local/cloud mutation paths as manual edits.

​
Required hosted services

  • Supabase auth, because AI capture is only available to signed-in users.
  • Supabase migrations through 20260922000100_ai_monthly_quota.sql, because monthly quota and budget RPCs are required.
  • Netlify Functions, because provider keys stay server-side.
  • An AI provider key for OpenRouter or Anthropic.
If no provider key is configured, the app falls back to the manual add form.

​
Provider variables

OpenRouter is the default low-cost path when OPENROUTER_API_KEY is present:
Anthropic remains supported:
AI_PROVIDER is optional. Without it, the server infers openrouter when OPENROUTER_API_KEY is set; otherwise it uses the Anthropic path.

​
Guardrail variables

All guardrails are server-only variables:
Monthly quota is per user and is charged only after a successful parse. Monthly budget is workspace-wide and is enforced with an atomic reservation before the provider call, so concurrent requests cannot all enter the model call after observing the same old spend.

​
Privacy model

The pasted text or uploaded screenshot is sent once to the configured model provider for extraction. SteadyRenew does not store or log the content. The database keeps only:
  • Per-user monthly AI capture counters.
  • Workspace-wide monthly aggregate token counts.
Function logs include request id, user id, command type, and token counts, but not the raw input.

​
Errors and fallback

Common error codes returned by /.netlify/functions/ai-parse-subscriptions: Users can always add or edit subscriptions manually when AI capture is unavailable.
