It's AI

Overview

It's AI is a writing-analysis service for estimating AI authorship, checking plagiarism, and correcting grammar and spelling. It is best suited to educators, publishers, recruiters, and teams that need repeatable document screening through integrations, while occasional users can sample it on the free tier. Its strongest case is breadth of workflow options and large paid-plan quotas; anyone making a consequential authorship decision still needs human judgment.

Key features

The detector covers text attributed to ChatGPT, Gemini, Claude, Grok, and other language models, with paraphrase detection included. You can paste text or upload PDF, DOCX, and TXT files. A 200-character minimum and displayed 500,000-character maximum make it practical for both excerpts and long submissions, although the relevant plan quota still determines how much you can process.

Deep Scan goes beyond an overall probability estimate: it marks sentences that appear AI-generated and supplies a word heatmap showing which passages influence the score. That extra evidence is useful for an instructor or editor who must explain why a document was flagged, rather than simply report a percentage. Plagiarism checking and grammar and spelling checks make the service useful for editorial cleanup as well as authorship review.

The homepage reports a 92.0 MGTD ROC-AUC score and 99.1% average accuracy across the GRiD, HC3, and GhostBuster benchmarks. Those figures can inform a comparison, but they do not turn an automated score into proof. The FAQ explicitly recommends weighing results with surrounding context and not treating them as the sole evidence of AI use.

Integrations span an API, Chrome Extension, ChatGPT Plugin, Python SDK, Canvas LMS, and Zapier; Moodle is marked coming soon. Canvas users can place checks inside SpeedGrader. Enterprise customers can use API access and batch processing, while the company offers onboarding support, demos, and product help at [email protected]. Its FAQ says submitted content is analyzed securely and is not shared with third parties after checks are complete.

Pricing

It's AI uses a freemium structure. The Free plan costs $0.00 and includes 4,000 words, file upload, three Deep Scans, 10,000 characters per scan, the Chrome Extension, and usage statistics. That is enough to evaluate the workflow or review a few short pieces, but not a dependable allowance for a class, publication, or busy recruiting pipeline.

Plus costs $84.00 per year (shown as $7 and $9 per month with annual savings). It allows 150,000 words, 10 files per upload, and 50,000 characters per scan, adding shareable reports, Deep Scan, plagiarism checking, and unlimited grammar checks. It is the sensible individual plan when those extra checks matter, though its word and upload caps constrain sustained high-volume work.

Premium is $144.00 per year (shown as $12 and $15 per month with annual savings), raising capacity to 300,000 words, 25 files per upload, and 100,000 characters per scan, with a ChatGPT plugin. Choose it for heavier personal or small-team use that needs the plugin; it does not include the larger Pro history allowance.

Pro is $20.00 per year, billed at $240/year and shown as $20 and $25 per month with annual savings. It includes 500,000 words, 50 files per upload, 500,000 characters per scan, and 365-day history. The published annual billing makes this a substantial commitment, but the larger files and retained history suit ongoing editorial or academic review.

The Educational Institution plan is $5.00 per year, billed at $5 per student per year with no monthly subscription. Each teacher receives a Pro subscription and 500,000 words per month, plus a student authenticity checker, priority support, and Google Classroom and Moodle integrations marked included soon. It is designed for institutions rather than individual students.

Enterprise starts at $95.00 per year, described as from $95/month and billed at $1,140/year. It provides 1M+ words with unlimited top-ups, 365-day history, 250 files per upload, API access, priority support, and extra words at $9.50 per 100,000. This is the appropriate route for automated or batch-heavy operations, not casual checking.

Platforms

It's AI is offered through the web, an API, and a browser extension. Its integration list adds a Chrome Extension, ChatGPT Plugin, Python SDK, Canvas LMS, and Zapier, with Moodle still coming soon.

Who it's for

Teachers and educational institutions gain SpeedGrader checks and institution-level teacher subscriptions. Writers, managers, recruiters, publishers, and ML engineers can use the broader language and authorship toolkit, while enterprise teams benefit from batch processing and API access. A casual user who only needs occasional checks should start free or consider a lighter alternative.

Pros and cons

Pros

• Broad analysis: AI detection, paraphrase detection, plagiarism, and language checks cover more than one review task.
• Useful investigation detail: Deep Scan's sentence highlights and word heatmap make a flag easier to examine.
• Workflow reach: API, extension, LMS, Zapier, SDK, and plugin options support varied teams.
• Large top tiers: Pro and Enterprise support long documents, retained history, and batch-oriented work.

Cons

• Free capacity is narrow: 4,000 words and three Deep Scans are primarily for evaluation.
• Annual commitment dominates paid plans: the listed pricing is billed yearly, which is less flexible for short projects.
• Scores require corroboration: the service itself says detection should not be the only proof of AI use.
• Some education integrations are unfinished: Google Classroom and Moodle are marked coming soon.

Alternatives

Choose TrustOriginality.ai if Android and iOS access matter, or if a low-volume monthly plan with multimodal verifications is preferable. ContentDetector.org suits readers wanting a free detector and converter across desktop platforms, with conversion limited to 1,000 characters.

AI Detectors.io is an option for a forever-free allowance with daily credits and 10,000 words per month. GPTZero is worth considering for its free 10,000-word monthly tier and annual Essential plan. Winston AI fits users seeking document and OCR scanning alongside AI and image detection. AI Detector Pro is a web-only alternative with a three-scan free tier and humanization plans. Detecting-AI.com offers no-account checks with generous daily detection limits. Detecto is another freemium option with text and image checks on its student plan.

Verdict

It's AI is a strong fit for educators and organizations that need AI estimates plus plagiarism and language checks across browser, LMS, API, and batch workflows. Choose it for Deep Scan's explanatory detail and the substantial Pro and Enterprise quotas. Look elsewhere if you need genuinely short-term billing, a very small occasional allowance, or an authorship decision that cannot tolerate reliance on contextual evidence.
