Pre-scan your undergrad essays and lab reports before Turnitin or Canvas sees them. Sentence-level highlights show exactly which lines read AI, with perplexity and burstiness signals so you can fix the prose instead of guessing. Calibrated for non-native English writers so formally-taught prose does not get over-flagged. FERPA-aware, no training on student work. Free to try. No card.
For undergraduates writing 4 to 8 essays a semester across mixed-policy courses, often inside tight midterms and finals windows. The realistic 2026 default is to draft fast, scan before submission, and fix the specific sentences that read AI.
College students face a specific stack of pressures that high schoolers and grad students do not. Volume is higher, policy varies by professor, and false positives hit hardest in the exact register most undergrads were taught to write in. Pre-scanning is the cheapest insurance against a wrongful integrity review for work that is actually yours.
Five to twelve pages of structured argument, due across two or three courses in the same week. Free tier covers casual single-essay scans up to 5,000 characters. Pro at $19.99 a month, or $14.99 a month on yearly, unlocks 10,000 character pastes and unlimited scans for the weeks where you are submitting on rotation.
Methods sections, discussion paragraphs, and procedural writing all run a higher false-positive risk than narrative prose because the genre rewards uniform sentence rhythm. Sentence-level highlights are the unlock here so you can see whether a flag is real AI residue or just the genre showing through.
Longer documents, multiple revision cycles, and an examiner who is now expected to check for AI. The 90-day Pro history matters when an examiner asks about a draft you submitted three weeks ago. PDF export keeps a defensible record of what you scanned and when.
TextSight is not a Turnitin replacement. It is the pre-submission scan that runs while you edit, so you have sentence-level context before your institution's report decides anything.
Write the essay in your usual editor. Using ChatGPT for an outline or to break writer's block is the realistic 2026 default and not the issue. Write the prose itself in your own voice from your own notes.
Open app.textsight.ai, paste the final draft, and scan. Free tier handles 5,000 characters in one paste. Pro handles 10,000. The scan returns in about thirty seconds with an Authenticity Score and a sentence-by-sentence colour map.
Above 75, submit. Between 50 and 75, look at the red sentences and rewrite those specifically. Below 50, the essay needs more substantial editing. The point is to fix the prose that is genuinely AI-shaped, not to game the score on prose you wrote yourself.
One round of editing usually moves a borderline score by 15 to 25 points. Re-scan, confirm you are in the safe band, then submit to your LMS. A typical four-page essay round-trips in about six minutes.

A single percentage is not a fix path. The TextSight result panel shows which sentences reacted and why, so you can edit the specific lines instead of rewriting the whole essay.
Every sentence is colour-coded by its own AI-likeness score. Red sentences clustered in one paragraph are a stronger signal than scattered yellows. Scattered yellows in otherwise structured prose often just mean you were taught to write formally. You read the pattern, not just the headline number.
Perplexity is how predictable your word choices are to a language model. Low perplexity reads AI-like. The score is shown per-sentence on Pro, which is the diagnostic context you need to decide whether a flag is real AI residue or just an unusually well-rehearsed thesis statement.
Burstiness is how much your sentence length and structure vary across the essay. ChatGPT defaults to uniform medium-length sentences. Real student writing has bursty rhythm: one short sentence, one long, one fragment. Low burstiness across an entire essay is the classic AI fingerprint.
Two scores side by side. Authenticity Score is the inverse-AI reading and predicts what Turnitin will say within 5 to 10 points. Plagiarism Risk catches copied passages and citation-risky phrasing in the same scan. Useful because Turnitin runs both checks, and pre-flighting both at once saves a round-trip.
Treating any single number as proof that a student used AI is unfair and unreliable. The 2026 expectation is that detection is one input among several. The design here is built around that expectation, on both sides of the conversation.
A low Authenticity Score means your essay reads more AI-like to the classifier. It does not by itself mean you used AI, and it does not by itself mean a professor will accuse you. False positives are real, particularly for ESL writers and for highly-structured academic prose where phrasing overlaps with AI defaults.
Run the scan and save the PDF report. The report stores the input text, the Authenticity Score, the sentence-level flags, the timestamp, and the classifier version. That is the format an integrity committee actually wants to see, and it gives you something specific to discuss instead of a vague denial.
Be honest with yourself when the score is below 50 on prose you thought was mostly yours. ChatGPT-assisted drafting often creeps further into the final essay than students remember. The fix is to rewrite those paragraphs in your own voice, not to rewrite them through another tool.
Several US universities have lost lawsuits in 2025 for auto-failing students on a single detector percentage. Most institutions now require sentence-level evidence, a student conversation, and a review of earlier drafts before any sanction. The score is the start of that process, not the end.
Native plugins are not shipped yet. Here is the honest 2026 picture of what works today and what is on the roadmap, so you can plan around it.
Draft inside Canvas, Blackboard, Brightspace, Moodle, or Google Classroom as you normally would. Before you click submit, copy the final essay text into TextSight at app.textsight.ai. Edit the flagged sentences in TextSight or back in your LMS, then submit the cleaned version. Round-trip is about six minutes for a typical undergrad essay.
Drag a DOCX, PDF, or TXT into TextSight if you wrote in Word or Docs. Pro accepts files up to 10,000 characters per scan and returns the same sentence-level result the paste-in workflow does. Useful when you do not want to lose formatting in copy-paste.
One-click scan from any web page including LMS submission views. Useful when you want to scan an assignment description, a peer review, or a paragraph from your own draft without leaving the tab. Available on Starter and above.
Canvas, Blackboard, Brightspace, Moodle, and Google Classroom plugins are on the 2026 roadmap. We are not promising dates while LMS plugin requirements keep changing each term. We would rather ship a working integration once than ship a thin wrapper that breaks every semester.
Student submissions are protected by FERPA in the US, by GDPR in the EU and the UK, and by local equivalents elsewhere. TextSight is designed to honour those rules out of the box, not as a paid setting you have to find.
Essays you submit for scanning are never used to train the classifier or any other model. This is a contract clause, not a configuration toggle. It applies on the free tier the same way it applies on Pro and Business.
The free tier needs no email, no account, no identity. For students worried about privacy or institutional disclosure, this matters. You can scan an essay without TextSight ever knowing who you are.
Scan history is private to your account. We do not share scan data with colleges, universities, instructors, Turnitin, or any third party. Your scans are not part of any institutional record, and your professor cannot pull them.
Any scan can be deleted from your history. On Pro you can delete individual records. Data retention is bound to your settings, and a standard DPA is available on Business and Enterprise tiers for student writing centres and tutoring teams.
