In their own words
Flatproof
Flatproof is web-based proofing software for client approvals. It handles images, PDFs, videos, audio, live websites, Figma links, presentations, and other uploaded files. A user can upload or import a proof, share one link, gather comments, manage versions, and record approvals. Clients and reviewers can comment and approve through that link without becoming paid seats. Annotation tools, approval workflow, version history, and guest reviewers are included. AI review inspects selected areas and creates private draft suggestions that the user may turn into feedback. Google Drive and Figma integrations are shown for importing source files or frames. Flatproof has a free plan with 200MB storage and 25MB uploads, plus unlimited creators and reviewers. Solo costs $5 a month with 100GB storage; Studio costs $29 a month with 1TB storage and bring-your-own AI key. The product is in beta, so bugs and interruptions may occur.
Proof Approve
Proof Approve is a web application for custom-product businesses that send proofs and collect customer decisions alongside an order. A customer opens a private link without an account, reviews a PDF, PNG, JPG, or JPEG proof, then approves it or requests changes. Approval and denial require a typed full-name signature, while denials also require notes explaining the requested changes. Proof history can record sent, opened, resent, approved, denied, and revoked events with timestamps, IP address, and browser information. The Free plan costs nothing and includes five proof sends monthly, one seat, private links, signed decisions, and 60-day retention. Paid plans start at $12 a month. Studio and Shop add automatic reminders; Shop also includes white-label branding and priority support. The service is designed to sit beside design, quoting, invoicing, scheduling, and production tools. Typed signatures are not guaranteed legally sufficient in every jurisdiction or transaction.
