Flatproof vs Notism

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.

Notism gives teams and stakeholders a shared place to review visual and video work and record sign-offs. Video reviewers can attach feedback to points on a timeline. On uploaded designs, users can add notes and sketches directly, including pencil, rectangle, and circle marks. Static screens can be linked through hotspots to create interactive prototypes. Teams can assign to-dos, track screen statuses such as in progress, for review, and approved, and create different versions to compare iterations. It runs in desktop and mobile browsers and on iOS and Android. Use requires an internet connection, JavaScript, and a fairly new browser; Chrome, Safari, and Firefox are recommended. The free plan is limited to one project and has limited features, with no support. A 15-day trial does not require a credit card, but changing plans during it ends the trial. Paid plans list different project, collaborator, archive, and storage allowances, along with features such as versioning and PDF export; their prices are not numerically listed. Notism is headquartered in Hamburg, Germany.
