How the free plan works

A find is only used when AI search works. It counts when a search uses AI matching and you open one of its results. Searches that return nothing useful, searches you abandon, keyword-only searches, and answers you read in the preview are all free. Opening several results from one search counts once.

When today’s finds are used

AI search pauses until 00:00 UTC. Keyword search, indexing and everything else keep working exactly as before — Inbox Search never stops being useful.

The free trial

Pro starts with 7 days free. A payment method is needed to start the trial. Cancel before it ends, from Settings → Manage subscription, and nothing is charged; otherwise the plan you chose begins when the trial ends.

Early users

Accounts that were active in the 30 days before the daily limit started keep unlimited AI search for free. If you were using Inbox Search then and see a limit, email hello@inboxsearch.app and we will put it right.

Why semantic search is the part that gets metered

Keyword search and indexing run locally in your browser, so they cost nothing to provide and are not worth charging for. Semantic search is what makes Inbox Search different from Outlook’s built-in search, so it is the part a paid plan is built around.

Your data is not part of the pricing

No plan changes how your email is handled. Processing happens on your device on every plan, and email content is never sent to our servers. See the privacy policy for what is and is not stored.

Payments

Pro is sold by Polar as merchant of record, which handles billing, VAT and sales tax. Prices include VAT where it applies. Subscriptions renew automatically until cancelled; see the terms of service for renewals, cancellation, refunds and price changes.
