Flask
Flask is a review collaboration space for video teams and their AI agents. According to its official website, it supports recording audio, providing frame-accurate feedback by drawing while speaking or typing, and also enables AI agents to read the feedback and modify the videos independently while preserving the source code and context. It covers scenarios such as version comparison, permission sharing, and outsourcing review.

What is Flask?
Flask's official website positions itself as a "Video review and collaboration workspace for teams and agents" — a space for video teams and their AI agents to review and collaborate on videos. Unlike traditional video review tools that only support uploading clips and adding comments, Flask allows feedback to be recorded as voice notes, with drawing capabilities and frame-specific precision, to convey subtle creative requests that can't be captured in text boxes. AI agents can also directly access and act on this feedback to edit the videos. The website also features dedicated comparison pages such as "Frame.io Alternatives" and "Video Feedback for Agents," making its positioning very clear.
Who is it for?
- Video teams and producers who receive more than a dozen revision comments for each delivery
- Creators who are already using AI agents for video editing or VFX and want to automate the feedback loop
- Producers who need to send links to external personnel while restricting editing permissions
- Specialized roles like VFX and color grading that require precision down to the frame and parameter level
Key features
5Frame-by-Frame Feedback
Supports voice recording with real-time drawing and drag positioning. The official website states that feedback can be precise to a specific frame to convey complex creative opinions.
AI Agent Editing
The official website states that the AI agent will read the feedback and revise the video through self-iteration; in the example, it completes all five pieces of feedback in one go, listing specific changes such as duration, color grading, and key light position.
Code and Files Coexistence
You can attach source code, timeline scripts, color grading files and materials when uploading a version. The official website states that all files needed to take over the work are stored here.
Version Organization & Comparison
Share via folders, compare multiple versions side by side, and set "who can view" and "who can edit" permissions separately.
Integrate with existing workflows
The official website states it is designed to fit into any traditional and agentic video workflow, and it provides an MCP entry and external sharing links.
How to use Flask
- 1Start with a short version for practice: Record a voice feedback with annotations, check if the other party can make the changes perfectly in one go, and then roll it out to the entire workflow.
- 2To have the AI edit the video, upload the source code and materials together; the official website is designed on the premise that "both code and context are saved".
- 3Use side-by-side comparison to confirm which version the changes are in; do not rely on verbal descriptions instead of watching the video.
- 4When sharing externally, distinguish between "view-only" and "editable" access, and grant only read-only permissions to external reviewers.
- 5For unreleased footage, first confirm the visibility scope of the link and do not send the entire source file via a public link.
