Built for supervisors and lecturers

For research supervisors and teaching faculty.

Undergraduate seminars, master's coursework, and doctoral supervision each carry a different shape of AI review in 2026. TextSight is tuned for all three contexts.

Undergraduate seminars and gateway courses

The pressure here is volume. A 30 to 80 student section drops papers in waves, and faculty want to know which submissions to read closely before grading. The TextSight workflow sorts the class by Authenticity Score, surfaces the bottom decile, and gives sentence-level highlights on each flagged paper, so the office-hours conversation is anchored on specific passages rather than a vague sense that something feels off.

Master's coursework and capstone projects

Higher stakes per submission, longer documents, and a stronger student incentive to use AI substantively. Pro accepts longer passages per scan, which covers most capstone chapters in two or three passes. The sentence-level evidence travels across passes, so a 40-page methods chapter can be reviewed in pieces without losing the picture of the whole.

Doctoral supervision and dissertation chapters

The supervisor relationship is built on trust, and a flagged scan is a delicate signal to raise. The right pattern is to scan chapters as drafts arrive, log results privately, and bring up concrete paragraphs in the supervision meeting only when the picture is clear. The 90-day history keeps the trail intact across a semester of chapter cycles without manual archiving, and the saved scan PDFs anchor the file if a formal review becomes necessary later.

Pre-Turnitin review

Sentence-level review before the institutional check.

Turnitin and iThenticate remain the institutional record. TextSight runs faster and earlier, with different signals, so faculty can read evidence rather than a single percentage.

Most universities run Turnitin's AI check or iThenticate as the official screen at submission. Those tools produce a percentage and an institutional record, which is the right shape of evidence at the policy layer. They are slow during peak grading weeks, the output is shallow, and the percentage does not tell a faculty member which paragraphs to look at.

How TextSight complements the institutional tool

TextSight runs the scan in seconds rather than minutes, surfaces sentence-level highlights with per-sentence confidence, and exposes the signals the classifier weighted. The percentage is similar in spirit but the working unit is the sentence, which is the unit a faculty member can act on. When the institutional Turnitin report lands later in the week, the two views together produce a much sharper picture than either does alone.

What professors see in the result panel

Each sentence is scored independently and colour-coded by confidence band, so the paragraphs that cluster red are the ones to read closely with the candidate, while the paragraphs that come back clean give a clear baseline. The classifier also exposes the underlying signals: perplexity reads how predictable each token is given the surrounding context, burstiness reads sentence-length variance across the document, and sentence-variance signals catch the narrow band AI-generated prose tends to land in. Each signal is shown individually so a faculty member can see why a passage flagged, not only that it did.

Per-section breakdown for long documents

Paste a chapter section by section, and the result panel keeps each pass in the same workspace. Section-level scores plus sentence highlights rebuild the picture of a 40-page document without losing precision, and the saved scans link together in the 90-day history for later reference.

Why two detectors rather than one

The classifiers under Turnitin and TextSight were trained on different corpora and use different signal weights. A passage that lands clean on one and flagged on the other is itself useful information, which usually means the writing sits in a borderline zone of academic register and benefits from a closer read. Faculty who run both as part of the standard workflow report a higher confidence in their grading calls and a lower false-positive escalation rate.

Academic integrity workflow

A conversation starter, not a verdict.

Most US R1, UK Russell Group, and EU research departments wrote formal AI policies between 2024 and 2026. The standard shape of the policy is documented evidence, a faculty conversation, and human judgement before any referral.

Step 1: Scan early, scan privately

Run the submission through TextSight after grading begins but before any conversation with the student. Save the scan to the 90-day history. If the score is clean and no paragraphs cluster red, the document is ready for normal grading. If the picture is mixed, treat it as a signal to read the work more carefully rather than as evidence of intent.

Step 2: Anchor the conversation on specific passages

The sentence-level highlights point to concrete paragraphs. The office-hours conversation is "walk me through your argument in section three" rather than "this feels AI-generated." The candidate has a fair chance to address the evidence and to explain their drafting process. The conversation, not the scan, is the primary evidence of the integrity call.

Step 3: Calibrate to department policy

If the conversation does not resolve the question, the saved scan PDF anchors the file for a formal referral. Most departments require evidence beyond a single classifier score, so the scan sits alongside the conversation notes, earlier drafts, and any institutional Turnitin or iThenticate output. Faculty judgement outweighs the classifier in every reasonable process.

Departments still drafting policy in 2026 often pull from faculty scan logs as precedent. Saving scans privately during the policy gap is itself useful institutional contribution.

LMS integrations

Where TextSight fits with your LMS.

No native LMS plugin yet. The current workflow is copy-paste or PDF upload into the TextSight web app, which most faculty find faster than an in-LMS plugin for typical seminar volumes.

Canvas, Blackboard, Brightspace, and Moodle

The standard workflow is to download the submission from your LMS as a PDF or paste the text directly into TextSight. Result panels save into the 90-day history with the original input, so a scan run on a Canvas submission stays linked to that submission in your private history. Native Canvas and Moodle plugins are on the 2026 roadmap. Blackboard and Brightspace are slated to follow once the Canvas integration is shipped and stable.

REST API for scripted workflows

Business tier includes REST API access, which institutions running scripted grading pipelines can use to scan submissions in batch. The API returns the same sentence-level evidence the web app shows, so a department writing custom Canvas LTI integration can wire TextSight into the grading queue without waiting for the native plugin.

Turnitin and iThenticate as the institutional record

Turnitin's AI check and iThenticate stay as the institutional submission-layer record. TextSight runs alongside as the working tool during grading, which is where the sentence-level evidence pays off. The two are complementary, not duplicate, and most faculty workflows use them in sequence.

Thesis and journal context

Graduate supervision and your own journal submissions.

Faculty sit in two chairs in 2026. TextSight is built so the same tool serves both, with the workflows kept separate inside one account.

Supporting graduate supervision

Scan dissertation chapters as drafts arrive. Log the result privately. Surface concrete paragraphs in the supervision meeting only when the picture is clear, and treat the conversation as the primary evidence of any concern. The 90-day history keeps the trail intact across a semester of chapter cycles without manual archiving, and the saved PDFs link to the file if a formal review board ever needs them later.

Pre-submission scan for your own journal papers

Nature began AI screening in 2024. Science, IEEE, ACS, and most major medical journals followed by 2025. Editorial-desk screening produces a number and a section-level breakdown, often before the paper reaches a human editor, and a flag at the screening stage can delay decisions by weeks. Run your draft through TextSight before submission, see which paragraphs the screener will likely flag, and either rewrite them in your own register or use the in-product AI rewriter to reset the language while keeping your content intact.

Post-publication checks and corrections

Some faculty use TextSight to spot-check sections of their own published work, usually before a press interview or a public talk where the underlying methods will be scrutinized. The 90-day history keeps the audit accessible, and the saved PDFs are useful evidence if a post-publication AI question lands in your inbox.

Grants and conference papers

NIH and NSF do not screen for AI today, but several program officers have signalled that screening is coming. ACM-track and several IEEE conferences already run submissions through detectors during desk review. A pre-submission scan adds five minutes to the workflow and removes a class of avoidable problems.

Privacy

FERPA and GDPR-aware data handling.

Student work is sensitive. TextSight is built so faculty can use it without rerouting student text into a training pipeline.

No training on submitted text

Submitted text is never used to train the TextSight classifier. The classifier was trained on internally licensed academic corpora plus public-domain writing, with student work explicitly excluded. Pasting a graduate seminar paper into TextSight does not contribute that paper to a future classifier release.

Private 90-day history on Pro

Every scan is logged in your account and viewable only by you. Pro keeps 90 days of history, Business keeps history indefinitely with optional deletion on request, and the audit log on Business is suitable for academic integrity review boards that want a consistent record across multiple graders.

FERPA and GDPR alignment

Standard DPA available on Business and Enterprise. Data residency on request for institutions with stricter requirements. Faculty should still confirm their own department or IRB position before routing protected human-subjects research data through any third-party detector, since the policy varies by institution and by research category.

FAQ

Faculty frequently ask.

Is TextSight a Turnitin or iThenticate replacement for professors?
No. Turnitin and iThenticate stay as the institutional record at the submission layer. TextSight runs alongside, before that submission, as a faster sentence-level review tool a professor can use during grading or while a candidate is still drafting. The detection signals are different enough that the two tools complement rather than duplicate each other, and the typical workflow keeps Turnitin as the official check and TextSight as the working tool.
How should a professor read the Authenticity Score on a graduate paper?
Read the score as a conversation starter, not a verdict. A score below 50 with two or three paragraphs glowing red is a useful flag to raise in office hours or in committee, where the candidate has a chance to walk through their drafting process. The sentence-level highlights point to specific passages, which keeps the discussion concrete rather than abstract, and the saved scan PDF anchors the file if escalation is needed later.
Does TextSight integrate with Canvas, Blackboard, Brightspace, or Moodle?
Not as a native LMS plugin yet. The current workflow is copy-paste or PDF upload into the TextSight web app, which most faculty find faster than an LMS plugin for the volumes a typical seminar produces. Native Canvas and Moodle plugins are on the 2026 roadmap, and Business-tier customers can request priority on specific LMS targets. The REST API on Business tier supports custom integrations for institutions running scripted workflows.
Can a journal AI screening flag a paper a professor wrote without AI help?
Yes, and it happens often enough that pre-submission scans are now part of many faculty workflows. Formal academic register, frequent passive voice, long methods sections, and references to standard frameworks all overlap with the patterns journal screeners look for. Running your draft through TextSight before submission shows which paragraphs an editorial-desk screener will likely flag, so you can rewrite them in your own register before peer review starts.
What is the academic-integrity workflow when a scan flags a student's work?
Calibrate the response to department policy. Most US R1, UK Russell Group, and EU research universities now require documented evidence and a faculty conversation before any formal referral. Scan the work, save the PDF, raise the specific flagged passages with the student in office hours or committee, and treat the conversation as the primary evidence. The scan is supporting material, not a verdict, and faculty judgement outweighs the classifier in every reasonable integrity process.
Is sending student work to TextSight a FERPA or GDPR issue?
TextSight does not retain submitted text for training, does not share it with other customers, and supports deletion on request. Pro accounts hold scans in a private 90-day history visible only to the account holder. For department-wide deployment, the Business plan ships with a standard DPA that most US, UK, and EU institutions accept without renegotiation. Faculty should still confirm their own department or IRB position before routing protected research data through any third-party detector.
Does TextSight work for dissertation chapters, qualifying exams, and theses?
Yes. Pro accepts longer passages per scan, which covers most dissertation chapters in two or three passes, and the sentence-level evidence is more useful when localized to one section at a time. The 90-day history keeps each chapter scan accessible if questions arise during the defense. Business tier extends history indefinitely and adds bulk PDF upload for cohorts of qualifying exam responses, which fits department-level grading committees.
Why use TextSight rather than the free detectors my students use?
Free detectors are tuned mostly on undergraduate writing samples and over-flag academic prose at the graduate and faculty level. Methods sections, literature reviews, and theoretical framings carry standard phrasing that often misclassifies on those tools. TextSight is calibrated on academic corpora, exposes the underlying signals rather than a single percentage, and ships with the 90-day history and PDF export faculty need for committee files and academic-integrity review boards.
