Who it is for

Built for Google Docs users, students, writers, and teams.

Drafting has migrated almost entirely into Workspace. Students write essays in Docs, content teams collaborate in shared Docs, researchers structure papers in Docs. The pre-publish pattern is the same across all three: paste, scan, fix, ship.

Google Docs is the default drafting surface for tens of millions of writers. The Gemini side panel and Help me write prompt are part of the standard workflow now. The realistic 2026 pattern is to use AI assistance while drafting and run a pre-publish scan on the final text before submission, delivery, or publication.

Students drafting essays in Docs

Most coursework now flows through Classroom or a shared Doc submission link. Students write the draft in Docs, paste into TextSight thirty minutes before submission, and edit any red sentences. The free tier covers three scans a day, which handles most weekly essay loads. Heavier dissertation work usually moves to Starter at 9.99 dollars a month.

Content teams collaborating on shared Docs

Editorial workflows live in Docs because of comments, Suggesting mode, and shared access. The standard pre-publish check is to paste the final Doc into TextSight, confirm the Authenticity Score is above 75, then move the piece into the CMS. Multiple authors and tracked changes do not change the workflow; the scan is on the final rendered text.

Researchers writing in Docs

Long-form research drafts and shared writing projects in Docs benefit from iterative scans. Pasting each major revision in keeps the Authenticity Score trending up as the draft improves. If the score plateaus, the issue is usually structural (paragraph templating, sentence-length flatness) and the sentence-level highlights point straight at the lines to rewrite.

The workflow

Paste from Docs into TextSight in four steps.

No native add-on yet (the Workspace Marketplace listing is on the 2026 roadmap). The paste flow takes under thirty seconds end to end and returns the same Authenticity Score the future sidebar will surface.

Step 1: Select All in your Doc

Open your Google Doc, press Ctrl+A (Cmd+A on Mac) to highlight the full body, then Ctrl+C (Cmd+C) to copy. Paragraph breaks, headings, and lists ride along with the plain-text payload. If you only want to scan one section, highlight that section instead and copy that.

Step 2: Open app.textsight.ai

Open app.textsight.ai in another tab. The detector tab is the default landing surface, so the text box is ready to receive the paste. No signup needed for the first scan; the free tier allows three scans a day before signup is required.

Step 3: Paste, hit Scan

Paste into the text box with Ctrl+V (Cmd+V), click Scan. Results stream back in three to six seconds for a 1,500-word draft. The Authenticity Score appears at the top, sentence-level highlights render below, and the per-sentence reasons (vocabulary tell, rhythm pattern, perplexity, structural symmetry) populate on hover.

Step 4: Fix the red sentences, re-scan

Toggle back to your Doc, rewrite the flagged sentences in place, then paste the revised draft back into TextSight for a second scan. Most pieces go from red to green in two or three iteration cycles. If a sentence flags on every pass, run it through the integrated AI rewriter (Light, Balanced, or Maximum) and paste the rewritten line back into the Doc.

vs Google's built-in AI

TextSight vs Google's Help me write and Gemini in Docs.

Google's own AI tooling inside Docs writes prose but does not score prose. TextSight is the audit layer on the other side of that pipeline.

Help me write generates, TextSight audits

The Help me write prompt in Docs and the Gemini side panel are drafting assistants. They produce paragraphs, expand bullets into prose, and rewrite for tone. Neither tool gives you a number for how AI-shaped the output is. TextSight is the inverse: it does not generate text, it scores text. The realistic 2026 workflow uses both, with Help me write on the drafting side and TextSight on the pre-publish side.

Gemini in Docs is calibrated as a flagged model

TextSight's classifier was trained on outputs from Gemini 1.5, 2.0, and 2.5 Pro alongside GPT-4, Claude, and other major models. Help me write drafts and Smart Compose long-form completions flag at the same fidelity as ChatGPT content. Writers using Gemini for outlines or first drafts get the same sentence-level visibility on the output that they would for any other model.

Suggesting mode does not address AI

Some writers think wrapping AI text in Suggesting-mode edits or inline comments will change the score. It does not. TextSight reads the final rendered text the way a reader sees it. To audit the original draft, reject all suggestions first or scan a fresh copy. The scan reflects what the next reader will read, which is the right thing to optimise.

Use cases

Three Google Docs patterns where TextSight earns its keep.

Students, content teams, and researchers all share the same paste-then-scan loop. The differences are in cadence and tier.

Essays drafted in Docs and submitted to Classroom

Students writing in Docs paste the final draft into TextSight before the Classroom submission deadline. Free tier covers three scans a day, which handles a typical week of coursework. Heavier essay loads (more than three to four drafts a week) move to Starter at 9.99 dollars a month. The pattern catches both genuine AI residue and false-positive flags from formally-structured academic writing.

Multi-author Docs across a content team

Shared Docs with multiple writers, comments threads, and Suggesting-mode edits scan the same as a solo Doc. The final rendered text is what TextSight scores. Editorial teams running a minimum Authenticity Score policy paste each piece into TextSight at the end of the review cycle, then push to CMS only above the agreed threshold (usually 75 or 80).

Research drafts iterated over weeks in Docs

Long-form research writing benefits from re-scanning at each major revision. The Authenticity Score trend across drafts is a useful signal: a draft that gets longer without the score moving usually has structural AI patterns (template paragraph openings, flat sentence rhythm) that need addressing earlier than expected.

Roadmap

Native Workspace add-on, on the 2026 roadmap.

Honest scope: there is no native Google Docs sidebar yet. The paste workflow returns the same score the future add-on will surface inline.

The planned add-on will dock a sidebar inside Docs, score the current document on demand, and render flagged sentences using the native Docs suggestion system so the writer can accept or reject AI rewriter rewrites inline. The underlying scan and the Authenticity Score model are identical to the web app.

Until that ships, the paste flow is faster than you might expect. Select All in your Doc, paste into app.textsight.ai, and the scan returns in three to six seconds for a 1,500-word draft. Long Docs above 50,000 characters work better as DOCX uploads on the Pro or Business tier, which preserves headings and list structure cleanly.

If a native add-on would meaningfully change your workflow (for example because you write in dozens of Docs a day and the paste step adds friction), tell us on the contact page. Demand signal directly affects roadmap priority. Sheets and Slides support is also tracked there.

FAQ

Google Docs users frequently ask.

Does TextSight have a native Google Docs add-on?
Not yet. A native Workspace Marketplace add-on is on the 2026 roadmap. Until that ships, the supported workflow is Select All in your Doc, copy, then paste into the TextSight web app at app.textsight.ai. Paragraph breaks, headings, and list structure carry over so the sentence-level highlights line up with your Doc layout. For long Docs above 50,000 characters, download the Doc as DOCX from File then Download then Microsoft Word, and upload the file on the Pro or Business tier.
Can TextSight detect Help me write and Gemini in Docs output?
Yes. The classifier is calibrated on outputs from the Gemini side panel in Google Docs, the Help me write prompt, Smart Compose long-form completions, and the older Duet AI Workspace assistant. Detection accuracy on Gemini 2.5 Pro Docs drafts is comparable to GPT-4 and Claude. The sentence highlights show why each flagged passage triggered, so writers can rewrite the specific lines instead of guessing.
How does the copy-paste workflow from Docs into TextSight actually work?
Open your Doc, press Ctrl+A then Ctrl+C (or Cmd+A then Cmd+C on Mac), open app.textsight.ai in another tab, paste into the text box, hit Scan. Results stream back in about three to six seconds for a 1,500-word draft. Paragraph breaks, headings, and bullet lists are preserved so the sentence-level colour map maps cleanly back to the position in your Doc. Multi-author Docs scan the same way; the score reflects the final rendered text regardless of who wrote what.
What about formatting, headings, and lists from my Doc?
Paragraph structure and headings carry over via plain-text paste. The classifier reads prose, not styling, so bold and italics do not affect the score. Bulleted and numbered lists are scored as separate sentence units. Tables in Docs paste as tab-separated text and are scored line by line. Inline comments and Suggesting-mode edits are not part of the copied text, so the scan is on the current rendered draft, not the change history.
Can I scan a Doc that has multiple authors collaborating?
Yes. Shared Docs with multiple writers scan the same as solo Docs. TextSight scores the prose itself, not metadata, so the result reflects the combined draft regardless of who contributed which paragraphs. For team workflows on Business, the same Doc can be re-scanned at each revision and the history view tracks the Authenticity Score drift across authors so leads can see where stock phrasing entered.
Which tier fits regular Google Docs writers?
Pro at 19.99 dollars a month, or 14.99 dollars a month on yearly, is the right fit for writers drafting five to fifteen Docs a week. It unlocks unlimited scans, 10,000 characters per scan, file upload for long Docs exported as DOCX, and the integrated AI rewriter for stubborn paragraphs. Casual users on three free scans a day stay on free. Business at 39.99 dollars a month (29.99 dollars on yearly) covers content teams running shared Docs across five seats.
Is the planned Workspace add-on going to be different from the web flow?
The planned add-on will surface the same Authenticity Score and sentence highlights inside a Docs sidebar, so the underlying scan is identical to the web app. The benefit will be removing the copy-paste step and rendering flagged sentences inline using Docs' native suggestion system. Until that ships in 2026, the paste workflow returns the same score in three to six seconds, which is faster than the sidebar round-trip would be on shorter Docs.
