What Leap AI does
Leap AI operates a text AI detection and humanization platform at tryleap.ai, serving students, professional writers, marketing teams, and academic researchers who need to verify or rewrite AI-assisted content. Its two core products are an AI Detector (free and unlimited, returning 0-100 AI probability scores with sentence-level color-coded highlighting based on perplexity and burstiness analysis) and an AI Humanizer that rewrites AI-generated text to read as human-authored while preserving meaning, citations, and tone. Supporting tools include a word counter, AI score checker, invisible character remover, AI text formatter, and contraction expander, plus an extensive learn hub with methodology, Turnitin-specific guides, and competitor comparisons.
The underlying technology is built on third-party foundation models — Anthropic's Claude accessed through Vercel AI Gateway — rather than proprietary in-house models. Proprietary value sits in application-layer engineering: per-sentence signal breakdown reporting (hedging density, burstiness variance, tier-1 vocabulary frequency, em-dash rate), a continuous evaluation harness benchmarking humanizer pass rates against Turnitin, GPTZero, Originality.ai, and Copyleaks, and prompt-level tuning that achieved a 6-point pass-rate lift in April 2026. A public HTTP API (beta) launched in April 2026 enables CMS and content-pipeline integration, and recent product updates cut humanizer p50 latency by 63% (37s to 13.6s).
The business runs on a product-led growth model: free, no-signup detection drives top-of-funnel acquisition, and paid monthly subscriptions on humanization drive monetization. Pricing is $9.99 (Starter), $19 (Pro), and $31 (Power) per month, with a $1.99 three-day trial, a 500-word lifetime free humanization tier, and a 7-day money-back guarantee. The company raised $1.4 million in seed funding in January 2024 led by Founders Inc., with participation from A-Level Capital, Carya Venture Partners, Gaingels, SHOR, and Untamed Ventures, and is led by co-founders Claudio Fuentes (CEO) and Alex Schachne.

Leap AI product offering
Product offeringCore offering
Leap AI is a SaaS platform that provides an AI text Detector (free, unlimited) scoring text 0-100 on AI probability using perplexity and burstiness analysis with sentence-level highlighting, and an AI Humanizer (paid subscription) that rewrites AI-generated text to read as human-written while preserving meaning, citations, and tone. The platform targets students, writers, and marketing teams who need to verify and humanize AI-assisted content so it passes scrutiny from detectors like Turnitin, GPTZero, Originality.ai, and Copyleaks.
Product overview
Leap AI offers a unified platform with two core products: an AI Detector and an AI Humanizer, both operating exclusively on text. The Detector (free, unlimited) scores text 0-100 on AI probability using perplexity and burstiness analysis, providing sentence-level highlighting. The Humanizer (free tier with 500 words, then paid plans from $9.99-$31/month) rewrites AI-generated text to bypass detectors while preserving meaning. The platform uses Anthropic's Claude accessed via Vercel AI Gateway. Supporting tools include a word counter, AI score checker, invisible character remover, AI text formatter, and contraction expander. The product suite includes extensive educational content including guides on AI detection methodology, perplexity vs burstiness, humanization guides, Turnitin guides, competitor comparisons (vs GPTZero, ZeroGPT, Undetectable.ai, Quillbot, Originality.ai, Turnitin, Copyleaks, Winston AI), AI citation guides, ethics content, and comparison pages with alternatives.

Products and services
- AI Detector A free, unlimited AI text detector that scores text 0-100 on AI probability using perplexity and burstiness analysis. Provides instant sentence-level color-coded highlighting showing which passages read as AI-generated and detects output from ChatGPT, Claude, Gemini, Llama, and Mistral models.
- AI Humanizer A paid AI text humanizer that rewrites AI-generated content to read as human-written while preserving meaning, citations, facts, and tone. Targets AI fingerprints such as tier-1 vocabulary, parallel structures, and uniform sentence length, and offers per-sentence before/after comparisons.
- Leap Public API (Beta) A beta public HTTP API that exposes Leap's detection and humanization capabilities for enterprise pipeline integration, including a /api/humanize endpoint with optional skip-detection parameters. Enterprise customers receive dedicated endpoints with higher rate limits.
- Word Counter A utility tool for counting words in text, part of Leap's supporting tools suite.
- AI Score Checker A utility tool for checking AI detection scores on text inputs.
- Invisible Character Remover A utility tool for removing invisible characters from text, part of Leap's supporting tools suite.

- Undetectable.ai: Undetectable.ai is one of the most prominent AI humanizer products on the market, targeting the same writers, students, and marketers who want AI text to bypass detectors. Leap competes directly for humanization conversion and runs comparison pages against it.
- Copyleaks: Copyleaks offers AI content detection and plagiarism checking for education and enterprise. It appears on Leap's comparison and alternative pages and is one of the baseline detectors Leap's humanizer is tuned against.
- Winston AI: Winston AI provides AI content detection for education, SEO, and publishing use cases. Leap has a dedicated comparison page and alternative page against Winston AI, indicating direct competition for similar customer segments.
- ZeroGPT: ZeroGPT is a widely used free AI detection tool aimed at students and general users. Leap explicitly competes with ZeroGPT on free detection top-of-funnel and maintains a dedicated vs/comparison page.
- Sapling AI Detector: Sapling.ai offers an AI content detector alongside grammar and writing tools used by customer-facing teams and educators. It targets similar writer and enterprise communication use cases as Leap's detector.
- Crossplag: Crossplag provides AI content detection and plagiarism checking for academic and content use cases. It competes for the same student and writer segments with comparable detection-first functionality.
Broad incumbents
- Turnitin: Turnitin is the dominant academic integrity platform with native AI detection widely deployed in universities. It is the primary detector students and educators reference, making it the institutional counterpart Leap's student segment works against or around.
- QuillBot: QuillBot is a broad paraphrasing and writing assistance platform with AI detection capabilities. It serves overlapping writers and students with a much larger feature set, positioning Leap's humanization as a more focused alternative.

Does Leap AI have an API?
Yes. Leap AI offers a public HTTP API (beta) for detection and humanization on Pro and Team plans. The API uses Bearer-token authentication with JSON request/response, rate-limited by plan tier. The `/api/humanize` endpoint accepts optional parameters including `detectionScoreBefore` (number 0–100, skips the before-score pass when already available) and `skipDetectAfter` (boolean, default false; skips the after-score pass for faster response). When `skipDetectAfter: true`, the response field `detectionScoreAfter` returns `number | null`. Enterprise customers receive dedicated endpoints with higher rate limits. The API enables pipeline integration with CMS workflows for automated detect → humanize → publish workflows. Developer documentation is at www.tryleap.ai/methodology.
