Diffchecker

What it does: Diffchecker compares text, code, and data online or offline, highlighting insertions, deletions, and edits.
Comparison features: Text comparison includes side-by-side and unified views, adjustable diff precision, custom ignore rules, syntax highlighting, real-time editing, and merging changes.
Other file types: The pricing page lists document, image, spreadsheet, and folder comparison features, including OCR, redlines, formula detection, and batch comparison.
Integrations: The pricing page lists Git and a Microsoft Word add-in for Desktop, and iManage for Diffchecker Legal and Enterprise.
iManage setup: Diffchecker Desktop can connect to an iManage Cloud account through its Preferences menu under Integrations.
Privacy: The website says browser comparisons run in the browser and are not published or shared unless saved and shared; Desktop comparisons run offline on the computer.
Security: The site states that traffic between the browser and Diffchecker is encrypted with TLS and that its information security program is certified to ISO/IEC 27001.
Desktop security: Diffchecker Desktop operates on the user's computer without interacting with Diffchecker web servers, according to its product page.
Limits: The pricing page lists Basic allowances such as five tries per month for unified view and real-time editing and ten tries per month for character-level differences and merge changes.
File size: The site states there is no file size limit, while noting that very large files take longer to render in a browser and Desktop is faster because it runs locally.
Trial: The Desktop product page advertises a 14-day trial with no credit card required.
Support: The pricing page lists priority support for Pro, Desktop, Legal, and Enterprise, with dedicated support channels and a service-level agreement for Enterprise.
Intended users: The site describes use cases for developers and engineers, writers and editors, and data and operations teams.
