The highest free AI humanizer quota in the category. 3 humanizations a day at up to 260 words each, all three modes (Light, Balanced, Maximum), sentence-level evidence on every scan, and the same AI humanizer model paid users get. Most competitors give 200 words once and lock the tool. TextSight's free allowance resets every day, indefinitely.
Most "free AI humanizer" results in 2026 are one-time previews dressed up as a free tier. TextSight scoped the free quota differently because the goal is to let writers actually use the humanizer, not to bait a signup.
Undetectable.ai's free tier is 250 words once. WriteHuman is 200 words once. HIX Bypass is 300 words once. StealthGPT is 150 words once. After the preview the humanizer locks until you upgrade. The marketing calls this "free" but the practical experience is a trial. None of these tools give you a workable quota for the second piece of content you want to humanize.
Three rewrites a day at up to 260 words each is enough to work through a stubborn paragraph at a time, a cover letter in a pass or two, or the flagged sections of an essay over a few days. The count resets every day and there is no monthly cap. That means a student with one essay a month, a job seeker polishing one application, or a freelancer running pre-publish QA can use the AI humanizer indefinitely without paying anything. The free tier is scoped to be useful, not to expire.
The free humanizer is not a stripped-down model. The Light, Balanced, and Maximum modes are byte-for-byte identical between the free tier and Pro. The detector that scores the output is the same classifier paid users get. The only differences are daily volume, file upload (paid-only), API access (Starter and above), and team workspaces (Business). The rewrite quality on free is exactly what you would get on Pro.
Honest accounting of what is in the free tier and what is not. No surprises, no "actually that feature is paid" footnotes mid-workflow.
Each rewrite takes up to 260 words, in any mode. Run a Balanced pass over one paragraph of an essay, a Maximum pass over the remaining red sentences, then a Light pass on a cover letter paragraph: that is your 3 for the day. Without an account that is 3 humanizations a day; on a free account it is 3 actions a day, shared with scans. The count resets daily and there is no monthly cap.
Light, Balanced, and Maximum all work on the free tier. Each one runs the same three-stage rewrite pipeline (sentence diversification, vocabulary shift, rhythm and cadence change) and reports a Humanization Score against TextSight's own detector on every output. There is no "free uses Light only" gimmick; pick the mode that fits the content.
Detection is free too: 3 checks a day without an account, or scans from a free account's same 3 daily actions at up to 1,500 words each. Each scan returns a Humanization Score plus colour-coded sentence highlights showing exactly which sentences read AI versus human. This is what tells you which sentences to rewrite in the first place. Most competitors hide sentence-level evidence behind a paid plan; on TextSight it is free.
The humanizer targets the voice patterns shared across ChatGPT, Claude, Gemini, GPT-4o, and the 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. Coverage on free matches coverage on paid.
You can paste text and run the humanizer once without entering an email or creating an account. Signup is optional and unlocks longer-term usage tracking and saved history; it is not gated. For sensitive content where you would rather not attach identity to the scan, the no-signup path is the safer route.
The humanizer result page is the same clean panel paid users see. No banner ads, no interstitial upsell prompts pasted over the rewrite preview, no aggressive newsletter modals. The free tier is funded by paid plans, not by monetizing your attention on the result.
3 scans a day covers several essays. Paid tiers scale up to 100,000 words on Business. Full details on the pricing page.

The free allowance covers a first pass and resets every day. These six things are not in free, and that gap is what the paid tiers exist to fill.
The free tier is paste-only on the web app. There is no API key. If you want to wire the humanizer into a CMS, a content automation pipeline, an outreach tool, or a custom writing app, you need Starter at $7.49 effective on annual for the Starter API tier, or Business for the full 100,000-word API quota.
Free is paste-only. PDF, DOCX, and TXT file upload starts at Pro. For one essay a month, paste works fine. For dissertation chapters, multi-section articles, or batched humanization of existing published content, file upload save real time.
Shared scan history, multi-seat workspaces, role-based access, and the per-organisation audit log all sit on the Business tier. 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.
Business includes branded PDF reports with your organisation logo on each humanizer output. Useful when humanizer output needs to be shared back to a client with provenance, or when a content agency needs a deliverable that looks like an internal QA artifact.
The bulk humanizer endpoint that accepts an array of documents in a single API call is Business-only. Right for batch processing dozens of pieces overnight or for any pipeline running humanization at scale. The free tier handles one piece of content at a time through the web app.
The TextSight Chrome extension surfaces humanization on any text field on the web (Google Docs, Notion, LinkedIn, your CMS). The extension humanizer is available from Starter upward. The free tier is web-app-only and works fine for paste-and-rewrite, just without the inline-on-the-page convenience.
The free quota covers most casual use indefinitely. Three patterns push users toward Starter or Pro within a month or two.
Active freelancers, SEO writers with weekly deadlines, dissertation students editing chapters, and content agencies running pre-publish QA all outgrow 3 humanizations a day fast. Starter at $7.49 effective on annual raises that to 40,000 words per month. Pro at $14.99 effective on annual gives 80,000 AI humanizer words, which covers almost every solo workflow. The math works out to roughly $0.30 per rewritten 1,000-word piece on Starter.
Any workflow that wires the humanizer into another tool (CMS publishing pipeline, sales outreach sequencer, batch content processing, custom writing assistant) needs an API key. Starter and above include API access with per-tier monthly word quotas. The free tier has no API path; paste-only on the web app is the entire surface.
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. Pricing is $29.99 effective on annual.
Plans can be downgraded back to free at any month boundary. The free tier stays available even after you have been on a paid plan, so if your needs drop back to one piece a month, you can return to free without losing access to the humanizer entirely. Annual billing is billed once and refundable within the first 14 days under the standard refund policy.
The humanizer is a tool, and the same way grammar checkers and rewriting tools have legitimate uses and dishonest uses, the free humanizer should be used inside a clear ethical scope.
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. Free-tier use cases that fit: pre-publish QA on one AI-assisted blog post a month, polishing one cover letter for a job application, voice-checking one essay before submission, running a diagnostic pass on your own writing if a detector flagged it as AI by mistake.
Content writers and journalists using AI for first-draft outlines often publish prose that reads flat and templated even when the underlying ideas are theirs. Running a Balanced AI humanizer pass before publication restores the voice variance that makes content perform with readers. This is closer to a professional copyedit than to disguise, and 3 free rewrites a day cover the flagged paragraphs of a piece over a day or two, indefinitely.
Using a humanizer to disguise ChatGPT work submitted under your name in graded academic contexts is dishonest regardless of which tool you use. The free tier cannot fix the underlying integrity problem there, 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.
