Is my contract data private?

Yes. This tool uses Chrome's built-in AI which runs entirely on your device. Your text is never sent to any server. It is safe for sensitive legal documents.

What browsers support this?

Chrome 138+ desktop with built-in AI enabled. Other browsers get a rule-based fallback that extracts dates, amounts, and legal terms without AI.

How accurate is the AI summary?

The AI provides a helpful starting point but should not replace legal advice. Always review important contracts with a qualified professional.

What if Chrome AI is not available?

The tool falls back to rule-based analysis that extracts dates, dollar amounts, key legal terms, and document statistics. It is still useful, just less comprehensive than the AI summary.

AI-Powered — Runs On Your Device

Private Contract Summarizer

Summarize contracts, agreements, and legal documents using Chrome's built-in AI. Your text is processed entirely on your device — nothing is uploaded or sent anywhere. Extract key points, deadlines, and obligations instantly.

This tool uses Chrome's built-in Summarizer API (Gemini Nano). It runs 100% on your device for complete privacy. Requires Chrome 138+ with AI features enabled.

This tool works in three modes: AI-powered (Chrome 138+), Transformers.js (any browser, downloads once), and smart analysis (instant, all browsers). Learn more.

Smart Analysis Mode: The tool will extract key patterns (dates, dollar amounts, parties) using rule-based analysis instead.

How This AI Tool Works

This tool uses Chrome's built-in Summarizer API, which runs Gemini Nano directly on your device. Your contract text is never sent to any server — it stays on your computer the entire time. This makes it safe for sensitive legal documents, NDAs, employment contracts, and business agreements.

If Chrome AI is not available (different browser, older version, or insufficient hardware), the tool falls back to a rule-based extraction that identifies dates, dollar amounts, named parties, and key legal terms.

What Gets Extracted

Key points — Main obligations, rights, and conditions
Dates & deadlines — Effective dates, termination, renewal
Financial terms — Amounts, payment schedules, penalties
Parties — Who is involved and their roles
Important clauses — Non-compete, confidentiality, liability

Privacy-First AI

Unlike cloud-based AI tools that upload your text to remote servers, this tool processes everything locally. Your sensitive contract data never leaves your browser. This is possible because Chrome downloads and runs the Gemini Nano AI model directly on your hardware.
