Our verdict on Flatproof
Flatproof is online proofing software for small studios and teams reviewing mixed creative assets. It supports file uploads, proof sharing by link, Google Drive imports, live website comments, and Figma frame review. Reviewers can annotate images with pins and areas, leave page-aware PDF comments, add timed video feedback, and approve work without becoming paid seats. The product also covers audio, presentations, and other uploaded files, making it suited to client approvals across varied deliverables.
Pricing uses storage rather than per-seat billing. The Free plan costs $0 and includes 200MB of storage, 25MB uploads, and unlimited creators and reviewers. Solo costs $5 per month and raises storage to 100GB while retaining unlimited creators and reviewers, with no seat math. Studio costs $29 per month, includes 1TB of storage and unlimited creators and reviewers, and adds the option to bring your own AI key. The published plans show monthly billing, and the product is presented as a public beta with a 50% discount on the first year through a founder offer.
For review operations, Flatproof combines version history, review context, approval workflows, queues, mentions, and notifications. AI-assisted review drafts are available as an optional workflow, while Google Drive and Figma provide the listed ecosystem connections. That breadth makes Flatproof a practical fit for small studios that want one web-based review process without per-reviewer charges. It is less suitable for teams that require native desktop or mobile platforms, broader integrations, or a product outside public beta. Choose it when low monthly cost and mixed-asset coverage matter more than platform breadth.
