About Diffchecker
What is Diffchecker?
Diffchecker is a comparison tool that finds differences between two text files, documents (PDF, DOCX, PPTX), and more. It highlights added, removed, and changed content at word or character level, making it easy to spot revisions. The tool solves the problem of manually reviewing file changes — whether you're a developer checking code diffs, a legal professional comparing contract versions, or a writer editing drafts.
Who is it for?
Diffchecker is best for developers, legal teams, project managers, and anyone who needs to track changes in text or documents. It is not ideal for image comparison or real-time collaborative editing. Use cases include reviewing pull requests, auditing contract redlines, and proofreading document updates.
Key capabilities
Diffchecker offers a side-by-side and unified view, real-time editor, syntax highlighting, AI-powered difference summaries, merge tool, and support for comparing PDFs, Word docs, PowerPoint files, and more. The Desktop app ensures your files never leave your device for added security. Plans range from a free Basic tier to Pro + Desktop ($15/user/month) and Enterprise ($40/user/month) with SAML SSO and iManage integration.
