Estimate AI-Likeness with Explainable Metrics
Paste any excerpt, toggle academic or strict modes, and receive a probability score with highlighted passages and shareable reports.
Paste text and click Analyze.
Overview
AI-generated prose is everywhere, but blunt detection claims often lack transparency. Our checker surfaces the signals behind its confidence score so editors, educators, and compliance teams can weigh context before making decisions.
The analyser runs entirely in your browser. No text leaves your device, which is critical when reviewing embargoed briefs, student submissions, or confidential copy drafts.
Key features
Explainable scoring
See burstiness, repetition, entropy, rare-word usage, and stopword ratios alongside a confidence score to understand the why behind results.
Highlight overlays
View colour-coded highlights for repetitive segments or statistically flat passages so you can revise or request rewrites quickly.
Academic & strict modes
Toggle heuristics tuned for formal writing or tighten thresholds when you need conservative outputs for compliance reviews.
Shareable exports
Copy plain-language reports, export JSON audits, or copy annotated HTML to discuss results with colleagues or learners.
How it works
- 1
Paste or type text
Import text via paste, keyboard, or the sample button. Longer passages (300+ words) return more reliable signals.
- 2
Choose analysis mode
Enable academic or strict mode to adjust thresholds before running the analysis, especially for technical or highly structured writing.
- 3
Run the analysis
Click “Analyze” to generate the probability score, key metrics, and highlight overlays instantly on the right-hand panel.
- 4
Review & export
Copy the summary, export JSON for record keeping, or download highlighted HTML to annotate feedback inside your LMS or CMS.
Use cases
Editorial QA
Check contributed articles or sponsored posts for AI-heavy phrasing before publication and request more human revision when needed.
Academic integrity checks
Scan essays or dissertations to spot sections that mimic machine-written cadence and provide students with improvement guidance.
Compliance reviews
Document due diligence when verifying disclosure statements or regulated content, keeping exports on file for auditors.
Examples & tips
Audit a press release
Paste the announcement copy, review highlighted boilerplate, and share the HTML export with PR leads for manual refinement.
Assess community submissions
Queue user-generated stories, run strict mode, and archive the JSON output as part of your moderation notes.
Coach a student rewrite
Highlight repetitive phrases, discuss alternative structures, and encourage mixing sentence lengths to improve burstiness.
Pro tips
- Combine the checker with the Word Counter to review readability before publishing.
- Maintain a manual audit trail whenever AI detection influences policy or grading decisions.
Frequently asked questions
- Is the score definitive?
- No detection method is perfect. Treat the score as a signal and combine it with human judgement and other evidence.
- Why is short text unreliable?
- Short passages provide limited data for statistical analysis. For best results, analyse 300+ words.
- Does the tool store submissions?
- Nothing is uploaded or stored. Refreshing the page clears your text and results.
- Can I automate this workflow?
- Use the JSON export to feed results into your moderation systems or data pipelines.
