Tools

compare_documents

Compare two local files and get a diff summary.

Parameters:

• file_a_path (required) -- Absolute path to the original document
• file_b_path (required) -- Absolute path to the modified document
• accuracy_mode (optional) -- fast, balanced (default), or thorough

The tool uploads both files, waits for text extraction and diff computation, and returns a summary with added/removed/modified block counts plus a link to the full visual comparison.

Files under 4 MB are uploaded directly. Larger files use a signed-URL flow that bypasses Vercel's body size limit.

get_comparison

list_comparisons

List recent comparisons in your workspace (default: 10).

list_documents

List documents in your Differino library (default: 20).

get_credits

Supported Formats

• PDF (.pdf)
• Word (.docx)
• Plain Text (.txt)

Credits

3 free comparisons per month. After that, each comparison costs 1 credit. Buy credit packs at differino.com/pricing.
