This is our editors' assessment out of 5, not an average of user ratings. The viewpoints on this page are written by AI from what we know about the product. They are not customer reviews.
According to OpenAITools.app telemetry verified on 2026-11-11, Flask (flask.do) is an AI platform indexed under AI Workflow generating 15.59K monthly visits with a month-over-month traffic delta of -28.72K (-64.8%). Its primary geographic market is United States (63.9% traffic share), and it operates on a Freemium pricing model. Top competing alternatives by monthly volume include SyncSketch (1.28M visits/mo), KROCK.IO (133.78K visits/mo), Flowith (324.68K visits/mo).
Voice notes right on the timeline changed our entire review loop.
Super smooth UI, though exporting takes a minute.
Game changer.
Clients actually leave useful feedback now instead of vague emails.
AI-synthesized perspectives grounded in live site inspection, pricing structure, and category benchmarks — presented as editorial viewpoints rather than individual customer testimonials.
Reviewers record their voice while drawing on the frame and seeking through the timeline, so nuanced notes arrive with exact timestamps instead of vague prose.
Feedback attaches to specific frames with headings, lists and images, is grouped into replies and threads, and can be exported or linked individually.
An MCP server lets AI agents upload cuts, browse projects and read feedback as timestamped comments with full transcripts, then iterate and upload new versions autonomously.
Keep multiple versions of every asset, compare them synced or unsynced, and store the code, context files and CHANGES.md that produced each version.
Group assets into shareable folders with custom labels, filters and advanced permissions, and send public links that always resolve to the latest version. Free and unlimited reviewers.
Flask rethinks video review around one idea: creative feedback is too nuanced for a plain text box. Instead of typing notes into a comment field, reviewers record their voice while drawing on the frame and scrubbing the timeline, so a note like "make it warmer, like the Golden Hour teaser" arrives with the exact frame, the reference still and the tone of voice attached. Every note lands on the timeline as a threaded, frame-perfect comment that is easy to reply to, resolve or export.
The second half of the product is built for agents. Flask exposes an MCP server, so an AI agent can browse projects, pull the timestamped feedback with full transcripts, make the edits in its own tool chain, and upload the next version back into Flask. Because each version ships with its source files, code and a CHANGES.md, the reasoning behind a cut stays next to the cut itself. Teams describe it as the moment they cancelled their old review tool.
The workspace handles the unglamorous parts too: version stacking, side-by-side version comparison, shareable folders with advanced permissions, invite links, custom labels and filters, Google Drive import, and image assets alongside video. Reviewers never need a paid seat, which makes it easy to send a link to a client and get real feedback rather than an email thread. Flask is made by Flask Ltd. in London and includes a free tier that covers every feature with an asset cap.
Editors upload a cut, producers talk and draw their notes on the exact frames, and the edit comes back with every note answered in one pass instead of another round of email.
Send clients a link: they watch without an account, sign in with one click and leave recorded feedback at no cost, while only the internal team needs paid seats.
Connect an agent through Flask's MCP server so it can read timestamped feedback with transcripts, make the requested changes in its own tools and upload the new version.
Keep vertical social cuts, teasers and opening titles side by side with dubbed or graded versions, compare them synced, and share the approved one with a link that always points to the latest.
