The free tier is accessible without account creation. Paste text, pick a mode, see the rewrite. No email, no password, no credit card on the first run. Most competitor AI rewriters force email verification before they unlock anything. TextSight kept the signup optional because the privacy reason most people open an AI rewriter in the first place is exactly the reason an email gate defeats the workflow. Free quota is 1,500 AI rewriter words a month and 3 detector scans a day, with all three modes available anonymously.
For an AI rewriter specifically, the input you paste is the same content you would not want linked to your real identity. Forcing an email gate before the rewrite runs creates a record that defeats the privacy reason people came to the tool.
Undetectable.ai requires email verification before the 250-word trial. WriteHuman requires signup before the 200-word trial. HIX Bypass requires signup before the 300-word trial. StealthGPT and similar AI rewriter rewriters both gate the rewrite behind an account. The "free trial" copy on these sites and the no-signup workflow people are actually searching for point at very different facts. In each case, the first rewritten sentence is bound to a verified email before it ever renders on screen.
The first AI rewriter run and the first detector scan require no email and no card. The entire 1,500-word monthly free quota is usable without an account if you stay on the same device. Anonymous usage is tracked by session and IP only, and no part of that tracking is linked to an identity you have not chosen to provide. Account creation exists for people who want history sync across devices, the .edu Pro discount, or team features, not as a precondition for using the product.
It is not the same word as free. Plenty of AI rewriters describe their trial as free while still requiring email verification before the rewrite runs. It is also not anonymity from the network: requests still go to TextSight servers and are logged for abuse prevention. What it actually delivers is the absence of an identity record bound to your pasted content, which is the specific risk surface people are usually worried about.
Honest accounting of what runs anonymously on the free tier and what does not. The same AI rewriter engine, same detector, same modes — only volume and integration features differ from paid.
The full monthly free quota is usable without an account. Paste, pick a mode, see the rewrite, repeat until the 1,500-word bucket is empty. The quota refreshes on the first of the next calendar month against the same session or IP. There is no per-day cap inside the monthly bucket and no surprise prompt for email partway through.
Light, Balanced, and Maximum all run on the no-signup path. None of the modes are gated behind an account, and the underlying three-stage rewrite pipeline (sentence diversification, vocabulary shift, rhythm and cadence change) is byte-for-byte the same code paid users hit. Pick the mode that fits the content, not the mode the signup wall lets you reach.
The detector runs anonymously too, up to 5,000 characters per scan and 3 scans per day. Each scan returns an Authenticity Score plus colour-coded sentence highlights showing which specific sentences read AI. This is what tells you which sentences need authenticity in the first place, and it is included in the no-signup workflow rather than locked behind a paid plan.
The AI rewriter on the no-signup path targets the same voice patterns across ChatGPT, Claude, Gemini, GPT-4o, and the broader GPT-4 family: the vocabulary cluster (delve, tapestry, navigate, multifaceted, robust, leverage), the polite-assistant openers (Certainly, Of course), the transition phrase stack (Furthermore, Moreover, In addition, In conclusion), and uniform paragraph rhythm. No source-model gating, no upsell modal between scan and rewrite.
Quota tracking happens against your session and IP for the duration of the month. No email is collected, no password is set, and no identity record is created in the database until you choose to sign up. Submitted text is not used to train the AI rewriter or detector regardless of signup status.
The AI rewriter output renders in the same result panel paid users see. No "create an account to view your rewrite" interstitial, no obscured output behind a blur, no aggressive email-capture modal pasted over the preview. The free tier is funded by paid plans, not by gating attention on the result.
1,500 words a month, anonymous, covers one essay or a few paragraphs. Paid tiers add history sync, file upload, API, and team features. Full details on the pricing page.

The first authenticity and full monthly free quota work without signup. These six things are not in the anonymous path, and that gap is what an account or paid plan exists to fill.
The single biggest practical reason to sign up on the free tier. Without an account, past rewrites stay tied to the browser session that produced them. Closing the tab loses access to the rewrite. A free signup adds 7 days of history that follows you between phone, laptop, and tablet. Pro extends history to 90 days, Business to unlimited. If you regularly need to revisit an authenticity later, the anonymous path stops being practical fast.
Students with a verified .edu email get Pro at $14.99 effective on annual rather than the full $19.99 monthly. The discount is gated behind email verification because the .edu check is the entire mechanism. Anyone using the no-signup path who would qualify for the discount should sign up specifically to take it; the savings are roughly $60 per year on annual billing.
Shared scan history, multi-seat workspaces, role-based access, and the per-organisation audit log all sit on Business. Right for content agencies running authenticity across multiple writers, university departments tracking submissions, and any team that needs a record of who rewritten what and when. Audit log implies user records, which implies signup.
The TextSight Chrome extension that rewrites selected text on any webpage requires authentication. So does the REST API for wiring the AI rewriter into a CMS, automation pipeline, or custom writing app. Both surfaces need an account to issue an API key or extension token. Starter and above include the API; the Chrome extension is available from Starter upward.
The anonymous path is paste-only. PDF, DOCX, and TXT file upload and URL ingest (paste a URL, the AI rewriter pulls article text) both start at Pro and require an account. For dissertation chapters, batched authenticity of published content, or multi-section articles, file and URL upload save real time over copy-paste.
Business adds branded PDF reports with your organisation logo on each AI rewriter output, useful when authenticity needs to be shared back to a client as a deliverable. The bulk AI rewriter endpoint that accepts an array of documents in a single API call is also Business-only. Both features assume a paid account and a verified billing relationship.
Honest specifics on what the no-signup path actually stores, how anonymous tracking works, and what changes when you sign up.
The 1,500-word monthly quota and 3 daily detector scans are tracked against an anonymous session cookie and your IP address. This is purely for quota enforcement; the cookie holds a random identifier and is not linked to any name, email, or identity until you choose to sign up. People on shared computers or shared IP networks should note that the quota counts against whoever used that session that month.
On the no-signup path, the request log records the input length, mode chosen, and timestamp for abuse prevention and capacity planning. It does not record the input text content alongside an identity, because no identity exists. After signup, scans are associated with the account so history sync can work; the input text is still not used for training in either case.
TextSight does not use submitted AI rewriter input or detector input to train either model. This holds equally for signed-in and anonymous usage. Most other free AI rewriters retain pasted text for analytics and some explicitly allow product training on submitted samples; the policy is published per vendor and worth reading before pasting sensitive content into any tool.
Anonymous sessions live in a browser cookie. Clearing cookies or opening a private window starts a fresh session with no link to prior usage. For shared library computers, internet-cafe stations, or any context where you do not want a usage trace, opening the AI rewriter in a private window and closing it afterwards leaves nothing behind beyond the standard server-side request log entry.
The no-signup path covers a one-off authenticity indefinitely. Four patterns push users toward at least a free signup, sometimes a paid plan.
Most writers draft on a laptop and revise on a phone, or vice versa. The anonymous path keeps history tied to a single browser session, which means past rewrites do not follow between devices. A free signup adds 7 days of synced history across every device logged into the same account. If your workflow involves more than one device, the inconvenience of re-pasting accumulates fast.
Students with a verified .edu email get Pro at $14.99 effective on annual rather than the standard $19.99 monthly. The discount is the largest single price reduction on the platform and requires signup specifically to verify the .edu address. Anyone who would qualify and plans to upgrade should sign up before paying.
Active freelancers, SEO writers with weekly deadlines, dissertation students editing chapters, and content agencies running pre-publish QA all hit the 1,500-word cap quickly. Starter at $7.49 effective on annual bumps the quota 13x to 20,000 words per month. Pro at $14.99 effective on annual gives 50,000 AI rewriter words. The math works out to roughly $0.30 per rewritten 1,000-word piece on Starter.
Multi-writer agencies, university departments running authenticity across student submissions, and publishing teams that need shared scan history all need Business. Shared workspaces, audit log, white-label PDF reports, and 5 team seats are scoped for exactly this case at $29.99 effective on annual. None of these features work without a real account model behind them.
No-signup access is a privacy feature, not an ethical loophole. The AI rewriter is built for authentic voice and calibration, and the scope of legitimate use is the same whether you sign up or not.
The AI rewriter is built to help writers whose work already includes their own thinking land that thinking in their own voice rather than in the institutional ChatGPT register. Legitimate no-signup uses include polishing one cover letter for a job application, running pre-publish QA on an AI-assisted blog post, voice-checking your own essay before submission, or running a diagnostic pass if a detector flagged your own writing as AI by mistake.
Freelancers testing AI rewriter fit before disclosing the workflow to a client, employees rewriting personal writing on a work device, and writers on shared computers all have real privacy reasons to use the no-signup path rather than create an account. None of these scenarios involve academic dishonesty, and the no-signup design exists to support them without requiring identity disclosure as a precondition.
Using an AI rewriter to disguise ChatGPT work submitted under your name in graded academic contexts is dishonest regardless of whether you sign up or stay anonymous. The no-signup path does not change the ethical analysis, and we would rather you used the detector to understand which sentences read AI and then rewrote them in your actual voice. The free tier was scoped to support legitimate use, not to enable academic misconduct at scale.
