Asked before the first scan.
Do I need separate accounts for each tool?
No. One account unlocks all 20 tools, the Chrome extension, the WordPress plugin, and the API. Scan history is shared across tools.
Why are these tools free?
Free is how serious writers try the detection engine. Single-text-box tools are cheap to run; volume scanning, long rewrites, file ingestion, and the API are the paid parts.
Can I use the tools without signup?
Yes — your first scan runs without an account. After 3 scans/day or 10,000 rewritten characters, you'll be asked to create a free account. No card, no verification gate.
Which tools require Pro?
None are paywalled. Pro unlocks unlimited scans, file upload, URL ingestion, and the 50,000-word monthly rewriter allowance.
Is there an API?
Yes — API access starts on Pro (5,000 calls/mo), with 10,000 on Business and 50,000 on Enterprise. SSE-streaming rewriter, visible rate limits. See API docs.
Can I embed these tools on my site?
No iframe widget yet — the supported path is the REST API on Business, rendering output inside your own UI.
Are the tools available on mobile?
Yes, every tool page works in mobile Safari and Chrome. An Android app with share-target support is in internal testing.
How accurate are free vs paid?
Identical. The free Detector calls the same model as the paid one. Paid buys volume and ingestion — accuracy never moves with your plan.
