Capabilities
Humanize & detect
Humanizer, paraphrase, AI detector, citations, and references.
Billing Tiers
Flexible pricing
Manage subscriptions, checkouts, and usage limits seamlessly.
A single revision call is the entry point. TurnitPass keeps that path simple, then adds the production pieces around it: detector-aware output, citation tools, metering, and key status.
Review snapshot
Ready
Internal mixed-topic review across common AI-writing signal checks.
API surface
7
Humanize, paraphrase, rewrite, detect, citation, bibliography, status.
Review card
Ready
review snapshot
A concise review card gives teams a sanity check before they wire output into their own product.
The first request should be obvious: assign words, create a key, send a draft, then inspect the returned text and usage summary.
Create an API key in your workspace after Google sign-in.
Call humanize, paraphrase, rewrite, detect, citation, bibliography, or status.
Read metering, remaining words, and response fields before exposing the result.
The public API follows the same workflow as the web product: revise, rewrite, check style signals, cite, build bibliographies, and review usage from one authenticated surface.

Why it works
Our developer platform is built around production requirements: secure key access, detailed usage logging, rate limits, and workspace management.
Generate multiple active keys and revoke them instantly without affecting your user account.
Transform endpoints consume credits from your plan balance, while citation endpoints are rate-limited separately.
API activity, usage metrics, and credentials are encrypted and stored securely.
Easily manage plans, usage tracking, and customer billing profiles.
Use API keys from your workspace. See the developer docs for request format.
Humanize, paraphrase, detect, citations, references, and account status—see the API reference.
API requests consume words from your plan balance. You can upgrade plans or top up your balance directly from your workspace.
