Differino

Differino gives document reviewers a way to compare PDF, DOCX and TXT revisions, including scanned PDFs, through a web app or API. It is most useful for occasional contract and report review where visual changes matter as much as wording. Its credit packs avoid recurring fees, but the free plan allows only one comparison.

Overview

Text and visual comparison modes let reviewers examine both wording and page appearance; redline output adds a familiar way to follow revisions. OCR-assisted extraction and rendered-page differences extend that approach to scanned or image-based PDFs, where searchable text may not be available. The 45 MB per-file limit applies across plans.

Free shares expire after 24 hours and PDF exports carry a watermark. Pro unlocks password-protected shares and watermark-free exports while credits remain. Free uploads and results are retained for 14 days, compared with 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, visual and redline comparison: A combination of wording and formatting review is useful when a change’s effect on a document’s layout matters, not just its text.
• Scanned-PDF support: OCR-assisted extraction and rendered-page differences make image-based documents reviewable, though the feature set is centered on documents rather than spreadsheet diffing.
• API and MCP access: A REST API and MCP server support workflows using Claude, Cursor and other MCP-compatible clients; this is the clearest fit for teams connecting comparison to other tools.
• Sharing and exports: Free users can share for 24 hours and export watermarked PDFs. Paid credits add password protection and clean exports, but only while credits remain.

Pricing

Differino is freemium, with one-time purchases rather than a subscription. The free plan costs nothing and includes one comparison, files up to 45 MB, PDF/DOCX/TXT support, two versions per document, 24-hour share links, watermarked PDF export and 14-day retention. It is enough to try a single review, but the one-comparison cap makes it unsuitable for ongoing use.

Paid packs are billed once and credits never expire: Diffito is 1.99 EUR for 10 comparisons (€0.20/comparison); Comparino is 6.99 EUR for 50 (€0.14/comparison); Revisiono is 14.99 EUR for 150 (€0.10/comparison). The larger packs lower the per-comparison cost, while the smallest keeps the initial spend down. Paid features include password-protected shares and watermark-free exports while credits remain. The 45 MB limit still applies.

Platforms

Differino is available on the web and through an API. Its MCP server provides another route for compatible clients; the service does not offer native spreadsheet comparison.

Who it's for

Differino is aimed at contract review for legal and business teams, and report review for finance, audit and operations. It suits people who need visual and text comparison, occasional OCR-assisted PDF review or API-connected workflows, and prefer a finite purchase to recurring billing. Finance teams whose main need is native spreadsheet diffing should look elsewhere.

Pros and cons

• Pro: Text, visual and redline comparison cover wording and formatting changes in one document-review workflow.
• Pro: One-time packs do not expire, so buyers avoid a recurring charge and can use comparisons over time.
• Pro: OCR-assisted review addresses scanned PDFs, while the 45 MB limit is consistent across plans.
• Con: The free plan’s single comparison, 24-hour shares and watermarked exports are restrictive for repeated or client-facing work.
• Con: Paid features depend on remaining credits, and Pro retention is 365 days rather than permanent.
• Con: It focuses on document comparison rather than native spreadsheet diffing.

Verdict

Differino is a sensible choice for legal, business and operations reviewers who need document-level visual and text comparison, especially when scanned PDFs or API/MCP workflows are part of the job. Its strongest case is the combination of OCR-assisted review and non-expiring one-time credits. Look elsewhere if you need frequent free comparisons, native spreadsheet diffing or a fully unrestricted free service.
