What is AI document comparison?

AI document comparison finds the exact differences between two versions of a document and then helps you understand whether the meaning changed too. DiffFind combines a deterministic, repeatable comparison that shows what changed with optional AI-powered semantic analysis that helps explain what it means.

Can DiffFind compare API requests and responses?

Yes. Load two URLs or two cURL commands to compare API responses, or paste JSON, YAML, or XML payloads to compare API requests and responses by path. You can also automate comparisons through the DiffFind REST API.

What is Semantic Find?

Semantic Find lets you search documents by meaning, not just exact words. It understands the intent of your search and can locate relevant passages even when the document uses different terminology, such as matching 'how much is the rent' to 'monthly lease payment.'

Does DiffFind store my files?

Not by default. Content submitted for comparison is processed to return a result and is not retained beyond what is needed to do so, unless you choose to save it, such as comparison history stored in your browser.

Which file formats does DiffFind support?

DiffFind compares plain text, JSON, YAML, XML, CSV, PDF, Excel spreadsheets (XLS and XLSX), and Word documents (DOCX). You can also load content from a URL or a cURL command.

Do I need AI to compare documents?

No. The core comparison is consistent and repeatable and works without AI. Semantic analysis is an optional layer you can add when you want to understand what a change means.

How do I call the DiffFind API?

Send a POST request to /v1/compare with your before and after content. The full request format is described in the OpenAPI specification at app.difffind.com/openapi.json.
