Differino

Differino is a document-comparison service for PDFs, DOCX and TXT, with web access and API support. It is best suited to people reviewing contracts, reports or other document revisions who want both wording and page-level differences. Its one-time credit packs avoid subscriptions, but the free plan allows only one comparison.

Overview

Differino shows document changes side by side in text and visual modes. That combination is useful when a revision affects layout as well as wording, and redline output gives reviewers another way to follow edits. Scanned or image-based PDFs are supported with OCR-assisted text extraction and rendered-page differences, though the 45 MB per-file limit applies across plans.

Sharing and retention terms matter for ongoing review. Free share links expire after 24 hours, and PDF exports carry a watermark; paid credits enable password-protected shares and watermark-free exports while credits remain. Free uploads and results are retained for 14 days, versus 365 days for Pro items. Anonymous-session files are deleted when the session ends. Differino says it does not use data for advertising or profiling and does not collect behavioral analytics or tracking data. Its privacy policy states that data is encrypted in transit with TLS 1.3 and at rest with AES-256.

Key features

• Text and visual comparison: Review wording alongside page appearance, with formatting changes and redline output. This is more useful for document revisions than a text-only check when layout matters.
• Scanned PDF support: OCR-assisted extraction and rendered-page differences help compare image-based documents that do not contain searchable text.
• API and MCP: A REST API and MCP server support workflows using Claude, Cursor and other MCP-compatible clients; this makes Differino relevant beyond manual web comparisons.
• File ceiling: Each upload can be up to 45 MB, including on the free plan.

Pricing

Differino is freemium, with one-time paid credit packs rather than recurring subscriptions. The paid packs offer more comparisons and remove the export watermark, but the 45 MB file limit remains. Password-protected shares and watermark-free exports apply while credits remain.

The free tier is a limited trial by use, not by time: it includes one comparison, and there is no free trial. Diffito suits a small number of occasional comparisons; Comparino and Revisiono lower the per-comparison cost for larger batches. There is no recurring renewal to manage, but the paid plans are credit packs rather than unlimited access.

Platforms

Differino is available on the web and through an API. Its MCP server connects with compatible clients. The listed platform support does not include desktop or mobile apps.

Who it's for

Differino is a sensible fit for legal and business teams reviewing contracts, and for finance, audit and operations staff checking reports. It also suits developers who want document comparison in an API- or MCP-connected workflow. Finance teams needing native spreadsheet diffing should look elsewhere: Differino focuses on document comparison rather than spreadsheet comparison.

Pros and cons

Pros

• Text and visual modes, formatting changes and redline output cover more than wording alone.
• OCR-assisted support and rendered-page differences extend comparison to scanned PDFs.
• One-time credits never expire, avoiding subscriptions and making occasional use practical.
• TLS 1.3 in transit and AES-256 at rest, alongside stated limits on advertising, profiling and behavioral tracking, give privacy-conscious reviewers useful assurances.

Cons

• The free plan allows just one comparison, with short-lived shares and watermarked exports.
• The 45 MB upload ceiling applies to every plan.
• Free retention is 14 days; even Pro items are retained for 365 days, which may not suit teams needing longer-term access.
• It does not provide native spreadsheet diffing.

Verdict
