Lynote pricing, free plan and limits

Last updated: 2026-09-23

Lynote is a browser-based AI workspace combining an AI text and image detector with a humanizer, YouTube transcription, document translation, and flashcard tools. Its open-source AI humanization engine has drawn 3,051 GitHub stars to date. Lynote's detector flags ChatGPT, Gemini, Claude, and other model output across 50+ languages.

About Lynote

Lynote is an AI writing and content-verification workspace founded by Jason Zhang and built by a six-person team based in Singapore. The company launched its integrated platform in September 2026, bringing an AI Detector, AI Image Detector, AI Humanizer, YouTube Transcript and Summarizer, AI Notes Generator, Document Translator, and Flashcards into one account, after the founders set out, in their own words, to build a tool that could act as a research assistant for people drowning in AI-generated and video content.

Unlike closed detectors such as Grammarly or QuillBot, Lynote publishes the core code behind its detection and humanization engines as open-source GitHub repositories, letting developers inspect how the tool scores a passage instead of trusting an opaque score. The AI Detector checks text and images against output patterns from ChatGPT, GPT-5, Gemini, Claude, LLaMA, and Mistral, while the Humanizer rewrites flagged passages sentence by sentence to reduce robotic phrasing without changing the underlying meaning. Buyers who want a general-purpose AI writing assistant rather than a detector-first tool should weigh Jasper, Writesonic, or Wordtune instead.

The platform suits students verifying an AI-assisted draft before submission, freelance writers polishing client copy, and researchers who would rather read a YouTube transcript than open a full video editor such as Descript or Veed just for the transcript. Its Notes Generator and Flashcards extend the same workspace into study prep, turning a lecture recording or PDF into review material inside the same tab, instead of moving notes into a separate highlighter such as Glasp or workspace such as Notion.

The whole platform runs entirely in the browser, with a companion Chrome extension, and the core Detector and Humanizer stay usable without creating an account. Reviewers report a paid Pro plan on top of the free tier for heavier usage and longer YouTube transcripts; anyone whose main need is standalone translation quality gets more mileage out of DeepL than out of Lynote's bundled version.

Its privacy policy commits to not training its AI models on user content by default, with API inputs deleted within 24 hours of processing, though the company has not published SOC 2, HIPAA, or ISO 27001 attestations. The wider set of tools competing for this use case sits in HokAI's AI content detection directory.

Pricing

Every core tool on Lynote, the Detector, Humanizer, YouTube Transcript and Summarizer, Notes Generator, Document Translator, and Flashcards, works for free without an account. 33 a month), lifting the Detector and Humanizer ceiling to 3,000 words per run and dropping the YouTube transcript length limit entirely. Lynote itself does not publish these figures on a public pricing table, so treat them as reviewer-reported rather than vendor-confirmed.

Writers pricing out cheaper generation-only tools can also compare Rytr, and teams optimizing published content for search might look at Surfer SEO alongside it.

Key Features

• AI Text & Image Detector: Flags AI-generated text and images from major chatbots and image generators, with Lynote's own page reporting a 99% accuracy rate across 50+ supported languages (not independently verified).
• AI Humanizer: Rewrites AI-drafted text at the sentence and paragraph level in 80+ languages while preserving the original meaning, usable free with no account required, per Lynote's own product page.
• YouTube Transcript & Summarizer: Converts any YouTube video into a timestamped transcript and a condensed summary in seconds, without requiring a channel login or download.
• AI Notes Generator: Turns documents, audio, video, and links into structured notes, built on the same engine published in Lynote's open-source lynote-notes repository.
• Document Translator: Converts documents between languages inside the same workspace used for detection and humanizing, avoiding a separate translation subscription.
• Flashcards: Auto-generates study flashcards from notes or documents to support spaced-repetition review, included on every plan per Lynote's pricing page.
• Chrome Extension: Runs the Detector, Humanizer, and YouTube Summarizer from a Chrome Web Store extension carrying a 5.0 rating from its first 11 reviews.

Pros

• The Humanizer and Detector are free to use with no account required, unlike competitors that gate their core check behind a sign-up wall.
• Lynote publishes its detection and humanization engines as open-source repositories on GitHub, letting technical buyers inspect the method instead of trusting a black box.
• Lynote's privacy policy commits to keeping AI-model training opt-in only, off by default even for API usage, based on the company's own published terms.

Cons

• No public pricing page exists on lynote.ai itself, so anyone comparing plans has to trust third-party review sites for the Pro tier's cost and limits.
• No SOC 2, HIPAA, or ISO 27001 attestation is published, which rules Lynote out for compliance-heavy legal, healthcare, or enterprise procurement reviews.
• The product is very new: its Chrome Web Store listing shows only 11 reviews and 32 users, so long-term reliability is unproven.
