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 humanizers force email verification before they unlock anything. TextSight kept the signup optional because the privacy reason most people open an AI humanizer in the first place is exactly the reason an email gate defeats the workflow. Without an account you get 3 humanizations a day at up to 260 words each and 3 detector checks a day, with all three modes available anonymously.
For a humanizer 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 humanizer 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 humanized sentence is bound to a verified email before it ever renders on screen.
The first AI humanizer run and the first detector scan require no email and no card. The no-account allowance (3 rewrites and 3 detector checks a day) 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 or team features, not as a precondition for using the product.
It is not the same word as free. Plenty of humanizers 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 humanizer engine, same detector, same modes — only volume and integration features differ from paid.
Three rewrites a day at up to 260 words each, with no account. Paste, pick a mode, see the rewrite, repeat until the day's three are spent. The count resets daily against the same session or IP, there is no monthly cap, and there is 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, 3 checks a day on its own allowance. Each scan returns a Humanization Score plus colour-coded sentence highlights showing which specific sentences read AI. This is what tells you which sentences need humanization in the first place, and it is included in the no-signup workflow rather than locked behind a paid plan.
The humanizer 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 day. 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 humanizer or detector regardless of signup status.
The humanizer 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.
3 humanizations a day at up to 260 words each, anonymous, covers a few paragraphs a day. Paid tiers add history sync, file upload, API, and team features. Full details on the pricing page.

The no-account allowance works without signup. These five 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 humanizations 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 a humanization later, the anonymous path stops being practical fast.
Shared scan history, multi-seat workspaces, role-based access, and the per-organisation audit log all sit on Business. Right for content agencies running humanization across multiple writers, university departments tracking submissions, and any team that needs a record of who humanized what and when. Audit log implies user records, which implies signup.
The TextSight Chrome extension that humanizes selected text on any webpage requires authentication. So does the REST API for wiring the humanizer 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 starts at Pro and requires an account. For dissertation chapters, batched humanization of published content, or multi-section articles, file upload save real time over copy-paste.
Business adds branded PDF reports with your organisation logo on each humanizer output, useful when humanization needs to be shared back to a client as a deliverable. The bulk humanizer 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 3 daily rewrites and 3 daily detector checks 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 count is shared with whoever used that session that day.
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 humanizer input or detector input to train either model. This holds equally for signed-in and anonymous usage. Most other free humanizers 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 humanizer 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. Three 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 humanizations 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.
Active freelancers, SEO writers with weekly deadlines, dissertation students editing chapters, and content agencies running pre-publish QA all hit the free cap quickly. Starter at $7.49 effective on annual raises it to 40,000 words per month. Pro at $14.99 effective on annual gives 80,000 AI humanizer words. The math works out to roughly $0.30 per rewritten 1,000-word piece on Starter.
Multi-writer agencies, university departments running humanization 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 humanizer is built for authentic voice and calibration, and the scope of legitimate use is the same whether you sign up or not.
The humanizer 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 humanizer fit before disclosing the workflow to a client, employees humanizing 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 a humanizer 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.
