It's AI

Overview

It's AI is an AI-writing detector with add-on checks for plagiarism, grammar, and spelling. It is best suited to educators and teams that need to review documents in existing workflows, though individual writers can use it for occasional checks. Its broad file support and integrations are useful; detection estimates still need human judgment.

Key features

The detector estimates whether text came from ChatGPT, Gemini, Claude, Grok, or other language models, and also supports paraphrase detection. You can paste text or upload PDF, DOCX, and TXT files; scans accept 200 to 500,000 characters. That range accommodates excerpts as well as long documents. Deep Scan adds sentence highlights and a word heatmap, giving reviewers clues about what contributes to a score rather than only a single estimate.

Plagiarism and grammar and spelling checks broaden the service beyond AI screening. The homepage reports a 92.0 MGTD ROC-AUC score and 99.1% average accuracy across GRiD, HC3, and GhostBuster benchmarks. Those are useful claims to weigh when comparing services, but they do not make a detection result conclusive: It's AI's FAQ recommends considering other context and not treating a score as sole proof of AI use.

Integrations include an API, Chrome Extension, ChatGPT Plugin, Python SDK, Canvas LMS, and Zapier. Moodle is marked as coming soon. Education workflows include checks in Canvas SpeedGrader; business uses include enterprise API access and batch processing. The FAQ says content is analyzed securely and not shared with third parties after checks are complete.

Pricing

It's AI has a free plan and paid plans, with paid pricing advertised from $7/mo on an annual basis. The plan figures mix annual totals and monthly equivalents, so check the billing term carefully:

• Free: free. Includes 4,000 words, file uploads, three Deep Scans, a 10,000-character scan limit, Chrome Extension, and usage statistics. It is a practical way to try the workflow, but three Deep Scans and the per-scan cap constrain regular review.
• Plus: $84 a year, billed $84/year and shown as $7 and $9/month with annual savings. Includes 150,000 words, 10 files per upload, 50,000 characters per scan, shareable reports, Deep Scan, plagiarism checking, and unlimited grammar checks. This is the lowest-priced paid tier and the clearest fit for individual users who want the wider toolset; its quotas are lower than the higher plans.
• Pro: $20 a year, billed $240/year and shown as $20 and $25/month with annual savings. Includes 500,000 words, 50 files per upload, 500,000 characters per scan, and 365-day history. It offers much larger quotas and a longer history, but costs more than Plus and the listed annual total is $240.
• Premium: $144 a year, billed $144/year and shown as $12 and $15/month with annual savings. Includes 300,000 words, 25 files per upload, 100,000 characters per scan, and a ChatGPT plugin. It may suit users who need that integration, though its word and file limits are below Pro's.
• Educational Institution: $5 a year, billed $5/student per year, with no monthly subscription. Includes 500,000 words per month per teacher, a Pro subscription for every teacher, a student authenticity checker, priority support, and Google Classroom and Moodle integrations marked as coming soon. Its per-student annual price and teacher allocation make it education-specific rather than a general team plan.
• Enterprise: $95 a year, billed from $95/month or $1,140/year. Includes 1M+ words, unlimited top-ups, 365-day history, 250 files per upload, priority support, and API access; extra words cost $9.50 per 100,000. This is the tier for high-volume or API workflows, not occasional individual checks.

Platforms

It's AI is available on the web, as an extension, and through an API. The integration lineup also includes a Python SDK, ChatGPT Plugin, Canvas LMS, and Zapier. Moodle and the educational plan's Google Classroom integration are marked as coming soon.

Who it's for

Teachers, students, educational institutions, and publishers are among the audiences It's AI targets. Writers, managers, recruiters, and ML engineers may find the combination of detection, language checks, batch processing, and API access useful. Occasional users can start with Free; people who need frequent scans, larger uploads, or workflow integration will need to consider a paid tier. Anyone making consequential decisions about authorship should treat the estimate as one piece of evidence, not a verdict.

Pros and cons

• Pro: Deep Scan's sentence highlights and word heatmap give reviewers more to examine than an overall score alone.
• Pro: Plagiarism, grammar, and spelling checks make it useful for document review beyond AI detection.
• Pro: API and education integrations, plus batch processing for business use, support workflows beyond the web interface.
• Con: The free plan's three Deep Scans and 10,000-character scan cap are restrictive for recurring reviews.
• Con: The paid tiers have different word, file, and character limits, and the displayed annual totals and monthly equivalents require careful comparison.
• Con: Detection results are estimates and should not be used as the sole proof of AI use.

Verdict

Choose It's AI if you need AI-writing estimates alongside plagiarism and language checks, especially in education or team workflows that can use its integrations or API. Its Deep Scan and broad scan limits on paid tiers add useful review tools. Look elsewhere if you only need a simple, occasional detector or need a result that can stand alone as proof: It's AI itself cautions that context matters.
