Why this fits
The developers use case, in detail.
Developers integrating AI detection into applications need a stable API more than a polished UI. AI Checker's REST API exposes the same detection model that powers the web app, with a clean JSON contract: send text, receive `{ score, sentences: [{text, score, flags}], model_match, confidence }`. The free tier supports 100 requests per day for development and prototyping. Production use cases — content moderation pipelines, education LMS integrations, marketplace authenticity systems — typically run on the paid tier with rate limits scaled to traffic. The API supports streaming responses for very long inputs, batch endpoints for periodic audits, and webhook callbacks for asynchronous workflows. Documentation includes example clients in TypeScript, Python, Go, and Rust. We do not charge per detected AI; pricing is per-request regardless of result, so there's no incentive to flag aggressively.
Developers FAQ
Frequently asked questions
Is AI Checker free for developers?
Yes. AI Checker has a free tier built for developers with no signup required. Higher-volume usage and team features are available on paid plans.
How accurate is detection for this use case?
AI Checker reaches 95-98% accuracy on unedited AI text across all major models (ChatGPT, Claude, Gemini, etc.). Accuracy stays above 90% on lightly edited or paraphrased content. Always pair the score with context — it's a strong signal, not a verdict.
Will my submitted text stay private?
Yes. Text submitted to AI Checker is processed in memory and is not used to train models. We do not sell or share content. Free tier submissions are not stored beyond the analysis itself.
Does AI Checker have an API for this workflow?
Yes. A REST API is available on all tiers — including the free tier with rate limits. Documentation includes example clients for TypeScript, Python, Go, and Rust.
What about false positives?
False positive rate on real human writing is approximately 1-2% across detection benchmarks. We surface this transparently — every result includes a confidence indicator. Programmatic AI text detection in applications, content platforms, and moderation systems.
