## Flask

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.

**Pricing & Plans:** Freemium. The Free plan costs $0 with no card required and includes every core feature plus 5 assets. Pro is $15 per member per month when billed yearly and unlocks unlimited assets with no GB limit, unlimited versions and unlimited free reviewers. Organization pricing is custom and adds advanced permissions, a longer download window, 4K playback, priority support and onboarding. Reviewers always leave feedback for free.

- **Voice, screen and drawing feedback:** 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.
- **Frame-perfect threaded comments:** Feedback attaches to specific frames with headings, lists and images, is grouped into replies and threads, and can be exported or linked individually.
- **Agent access via MCP:** 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.
- **Version stacking and side-by-side compare:** Keep multiple versions of every asset, compare them synced or unsynced, and store the code, context files and CHANGES.md that produced each version.
- **Organized sharing with permissions:** 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.

**Strengths:** Feedback is recorded with voice and drawing on the frame, which conveys intent far better than written comments; Reviewers are always free and unlimited, so clients and stakeholders never consume a paid seat; Native MCP support lets AI agents read feedback and upload new iterations autonomously; Version comparison, source files and change notes live alongside the video, keeping context in one place

**Limitations:** No storage-style download guarantee: the original file is removed after the retention window on Free and Pro plans; Pro is priced per member and billed yearly, so small teams pay for every person who uploads or manages assets; The agentic workflow assumes familiarity with MCP-based tooling, which can be a learning curve for traditional production teams

## RunningHub

RunningHub is an all-in-one AI content creation platform built around cloud ComfyUI. Instead of installing Stable Diffusion, Flux, ControlNet, and LoRA setup on your own GPU, you run workflows on RunningHub's servers and interact through a browser. The platform supports importing and running ComfyUI graphs, then turning them into polished single-click "AI Apps" that non-technical users can operate with simple prompts.

Beyond the workflow engine, RunningHub bundles a broad creative toolkit: text-to-image and text-to-video generation, image-to-image and image-to-video conversion, inpainting, outpainting, and upscaling powered by self-developed models. An infinite canvas and rapid-creation templates help users assemble campaigns, product visuals, and short videos. The homepage also showcases a community gallery of featured workflows, model APIs, and viral video templates.

RunningHub follows a freemium, credit-based model with free daily usage and subscription tiers for heavier production. It targets creators, small studios, and developers, and offers workflow, model, LLM, and app APIs so teams can embed generational capabilities into their own products.

**Pricing & Plans:** Freemium with daily free credits and pay-as-you-go credits; subscription tiers unlock higher concurrency, member discounts, and advanced models. API usage is priced separately.

- **Cloud ComfyUI:** Run, import, and share ComfyUI workflows in the cloud without local GPU hardware.
- **AI Apps Builder:** Publish a workflow as a single-click AI app that anyone can run with simple inputs.
- **Image & Video Generation:** Use hosted image and video models, including self-developed upscaling and enhancement tools, from one dashboard.
- **Developer APIs:** Integrate generation into your product via workflow, model, LLM, and app APIs.
- **Template Library & Community:** Explore a gallery of community workflows, viral video templates, and creator rewards.

**Limitations:** Complex workflows have a learning curve; Credit-based costs add up for heavy video generation; Best experience assumes some ComfyUI familiarity
