Pre-scan your essay before it goes into Google Classroom, Canvas, Schoology, or Microsoft Teams. Sentence-level highlights show you exactly which lines a teacher's detector will react to, so you have time to revise honestly. Calibrated for high school writing, so structured five-paragraph essays from ESL students do not get over-flagged. Free tier, no email needed for your first scan. Built for grades 9 through 12.
High school writing is its own thing: shorter essays, tighter rubrics, and a teacher who knows your voice from class discussion. The detection conversation in high school looks different from the one in college, and the tool should respect that.
You are not writing dissertations. You are writing five-paragraph essays for English, history responses for AP US, lab discussions for Biology, and reflective pieces for advisory. Each of those has its own voice and its own length, and a detector that thinks every formally-taught essay is AI-written is the wrong tool. TextSight is calibrated around school-age writing, not against research papers.
Five-paragraph essays, book responses, in-class timed writes that get typed up at home. Most of these come in under 5,000 characters and fit comfortably inside the free tier's per-scan limit. You can pre-scan three pieces a day at no cost.
AP Lang, AP US History DBQs, AP Research and AP Seminar performance tasks. College Board requires that any AI use be disclosed for those last two. Pre-scanning your own draft is a sensible habit when the stakes are college credit and your transcript is being read by admissions a year later.
Extended essays, IB internal assessments, AS and A2 coursework, and the personal statement that goes on UCAS or the Common App. These are the highest-stakes writing pieces in high school, and they are also the ones where a false-positive AI flag is most painful. The pre-submit scan is the cheapest form of insurance you can buy yourself.
TextSight is not a way to launder AI text past your teacher. It is a way to read your own writing the same way the classroom detector is going to read it, before you click submit.
In Google Docs or Microsoft Word, the way you normally write. Finish the essay first. Do not scan a half-draft, because the score will be noisy.
Copy the text into app.textsight.ai, or upload the DOCX. The free tier handles up to 5,000 characters per scan, which is roughly 800 words and covers most high school essays. Your first scan does not need an email.
Look at which sentences are coloured red or yellow. Red clusters in one paragraph are the strongest signal a teacher's tool will react to. Scattered yellows in otherwise structured prose usually mean you write formally, not that you used AI.
Rewrite the flagged sentences in the way you actually talk in class. Mix sentence lengths. Add a specific example from your own life or course material. Re-scan if you want a second read. The goal is not to chase a 100 score; it is to make sure the writing reads as yours.

A percentage on its own is not useful for a high schooler. The TextSight result panel shows which sentences a detector reads as AI and why, so you can decide where to revise.
Every sentence is colour-coded by its individual AI-likeness score. Red sentences clustered in one paragraph are the strongest signal a teacher's tool will react to. Scattered yellows in otherwise structured prose are usually a false-positive pattern that comes from formal essay-writing, not AI.
Each paragraph is rolled up into a card with its own score. If your introduction scores low and the body of the essay scores high, that is useful information for where to revise first.
Perplexity is how surprising your word choices are. Burstiness is how much your sentence lengths vary. AI writing tends to have flat, predictable phrasing and even-length sentences. Human writing varies. The result panel shows these signals as bars so you can see the pattern instead of just reading a number.
One headline number, calibrated so above 75 reads as human, between 50 and 75 is borderline, and below 50 reads as AI-heavy. Think of it as the temperature reading, not the diagnosis.
Using a detector to auto-fail a 15-year-old on a single percentage is a bad outcome. The 2026 expectation is that detection helps students and teachers have a conversation about a draft, not deliver verdicts on a student.
A score is a signal about how a detector will read your draft. It is not a measurement of whether you committed academic misconduct. If you wrote the essay yourself and the score is low, the move is to revise in your own voice, not to give up on the assignment. If you used AI assistance, the move is to disclose that to your teacher under your school's honor code.
Districts that auto-fail on a single detector percentage produce bad outcomes and have already led to lawsuits in the US and UK. The defensible path is conversation first, sentence-level evidence second, decision third. The percentage is one input, not a verdict.
Detectors trained mostly on American student writing over-flag ESL students, students taught Oxford-style English, and students who write formally because that is what their teacher taught them. If your draft reads AI-heavy and you know you wrote it yourself, the most likely explanation is formal structure, not deception. Revise for sentence variety, not for honesty.
Run a piece of writing you know is yours, an in-class essay or a journal entry, through the scanner. The score you get there is your baseline. Compare future scans to that baseline, not to an absolute number. A score that drops 20 points below your baseline is worth a closer look. A score that matches your baseline is your normal writing voice.
Native LMS plugins are not shipped yet. Here is the honest 2026 picture of what works today and what is coming.
Google Classroom is the biggest LMS in US high schools and is also widely used in UK secondary, Canada, and Australia. Write your essay in Google Docs, paste it into app.textsight.ai or download a DOCX and upload, read the highlights, revise, then attach the final doc in Classroom as you normally would. The whole pre-scan step takes under five minutes.
Canvas is increasingly used in US public high schools and Catholic schools. The same draft-paste-revise-submit workflow applies. Many Canvas instances run Turnitin's AI check on submission; pre-scanning your own draft is the cheapest way to see what Turnitin is going to flag before it flags it.
Schoology is common in mid-Atlantic and Midwest US districts. Microsoft Teams for Education is common in UK and EU secondary schools. Both work the same way: draft on the side, scan on TextSight, revise, submit.
Many US high schools run Securly, GoGuardian, or Lightspeed filters on student Chromebooks. TextSight is a normal HTTPS website with no on-device install required, and the free tier does not require a sign-in, so it works on filtered student devices in most schools. Check your school's allowed-sites list if you cannot reach app.textsight.ai.
Google Classroom and Canvas plugins are on the roadmap. We are not promising dates while the integration partners change their plugin requirements; we will not ship a thin wrapper that breaks every term.
High school students using a detector should not have to give up identity, family contact, or training data to do it. TextSight is designed around that.
Your first scan does not need an account. Paste the text, read the result, close the tab. Nothing about you is stored, nothing is associated with your name, nothing reaches your parents or school unless you choose to share it.
Student text submitted for scanning is never used to train the classifier or any other model. This applies to free-tier scans and to logged-in scans equally.
TextSight is intended for users aged 13 and older. We are not a COPPA-regulated service for under-13s. Middle school students under 13 should ask a teacher or parent to run a scan on their behalf rather than create an account.
For US schools subject to FERPA, the free-tier no-account flow keeps student writing outside of any system that needs FERPA consent. Logged-in scans are bound to the student's own account, deletable at any time, and not shared back to the school unless the school separately licenses the Business tier and the student joins a school workspace.
Any scan can be deleted from a logged-in history. Free-tier scans without an account are not stored to begin with, so there is nothing to delete.
