compare & share

Paste two texts, compare, share the diff

Frequently Asked Questions

The only text compare tool that lets you share the result.

What is compare-share.com?

A free online text comparison tool. Paste two versions of any text, get word-level differences highlighted side by side, and share the result as a unique link — no account needed, no install, works in any browser.

How does it work?

  1. Paste your original text into Text A and the updated version into Text B
  2. Click Compare — differences appear instantly, highlighted word by word
  3. Click Share — get a unique link. Anyone who opens it sees the same comparison, no login required

Your text never leaves your device until you click Share.

Why use this instead of asking an AI?

When you paste two large texts into ChatGPT, Claude, or another AI and ask "what changed?", you're consuming tokens just for the comparison step. compare-share.com does that in your browser, instantly, for free. Diff first, then paste only the specific differences into your AI conversation.

What makes compare-share different?

Most text comparison tools show you the diff — and stop there. compare-share.com lets you share it. Every comparison generates a unique URL you can send by email, drop in Slack, or post publicly. The recipient sees the highlighted diff exactly as you do — no screenshots, no attachments. Other tools that offer shareable links require a paid account. Here, sharing is free.

What can I use it for?

  • Contracts and legal documents — show exactly which clauses changed
  • Website copy — review edits before publishing, share for team approval
  • Policy updates — distribute the diff as a link, not a document
  • Freelance deliverables — show clients what changed between drafts
  • AI-generated content — compare two AI outputs before choosing one
  • Email and proposal drafts — confirm revisions before sending

How long do shared links stay active?

Free shared links stay active for 30 days. After that, the link expires and the text is permanently deleted from our servers. The expiry date is shown on every shared view so the recipient knows how long it will be available.

Is my text kept private?

  • Without clicking Share — the comparison runs entirely in your browser. Nothing is sent to our servers.
  • After clicking Share — your text is stored securely and deleted automatically when the link expires.

For highly sensitive material — confidential contracts, personal data, anything regulated — use an offline diff tool instead.

Do I need an account?

No. No sign-up, no email address, no password. Compare and share instantly. The person receiving your link doesn't need an account either.

Is there a character limit?

Each text field supports up to 10,000 characters. For longer documents, split the content into sections and compare each part separately.

Is it free?

Yes. Comparing and sharing are both free, with no login required.
