Assist
Limits & Billing
One billable unit: the answered question. Search is free and unlimited, forever. Every site answers 250 questions free each month; beyond that it's $0.01 per question.
How Billing Works
- A question = one AI-composed answer. Follow-ups each count as one question. Searches, config fetches, and handoffs are free. Cached answers still count — metering is per question asked.
- 250 free per site per month. No credit card required; the allowance resets on the first of the month.
- Beyond that: $0.01 per question ($10 per 1,000), billed against your account's prepaid balance under your usage budget — the same pay-as-you-go machinery as the rest of Edge. No plans, no seats, no per-page fees.
- Extended conversations meter at 2× on their deep turns — longer threads carry more context, which costs more to produce. It's an optional per-site setting.
Worked examples are on the pricing page.
What Happens at the Cap
When a site reaches its monthly allowance (and there's no usage budget to continue against), the widget degrades gracefully rather than breaking:
- Instant search keeps working — it's free and unlimited.
- Ask is paused: the widget shows a capacity notice and stops offering AI answers; the API returns
429 { "error": "monthly-limit" }. - Answering resumes automatically when the month rolls over, or immediately when you set a usage budget in Billing.
Your site's Overview page in Control shows this month's usage against the cap, with the same warning thresholds your bill sees.

Paid Features
A site becomes "paid" the moment your account has a usage budget. That unlocks, at no extra flat fee:
- Higher ingestion ceiling — 10,000 pages instead of 500.
- White label — name the assistant after your product and remove the "Powered by Edge Assist" badge.
- Extended conversations — longer threads with a deeper memory (metered 2× on deep turns).
- Cache pre-warming — answer likely questions ahead of time (rolling out; each answer meters at the normal rate).
