Kino AI Launches a Video Editor Where Humans and Agents Share One Timeline

TL;DR

Kino AI, a YC S23 company, launched its rebuilt video editor on Hacker News on November 4. It is a multiplayer timeline where Claude Code and Codex agents cut footage next to you, with every edit, motion graphic and comment expressed as code on top of Remotion, and every project, clip, frame and comment addressable by URL. The editor is free with capped agent calls; Pro is $25 per editor per month. The agent is a first-class user here, with the same access to timeline state that you have.

What shipped

Three jobs live in one app. Storage: drop in anything from iPhone clips to 6K camera originals, and ProRes, DNxHD, Blackmagic RAW, RED R3D and Avid OP-Atom MXF play without a transcode, with the timeline rendered on WebGPU and video decoded through WebCodecs. Indexing: every clip that lands is transcribed, described shot by shot and face-detected, so you can search what was said, what appeared on screen and who was in it, then filter by codec, camera, lens or shoot day. Editing and review: a what-you-see-is-what-you-get timeline over a Remotion project, share links where comments land directly on the timeline, and a control that routes any comment to your agent.

The desktop app ships for macOS, Windows and Linux. In the browser it is Chrome-only, because the timeline needs WebGPU and decoding needs WebCodecs; Safari, Firefox and Edge are out for editing. Everything has a URL: a project, a clip, a single frame, the line of code that draws it, each comment and reply. You paste those links into your agent instead of describing which of two thousand timeline items you meant.

Agents plug in through MCP: Claude Code, Codex, an in-app chat, Grok Bot and Devin. The docs describe the logical endpoint plainly: send Devin one message and it installs Kino on its own cloud computer, signs in as you, and edits while you are away.

The long way around

Founder Luke Igel cut his teeth co-directing a 3.5-hour archival documentary at MIT, work that was mostly logging footage, wrangling hard drives and keeping a planning spreadsheet honest. Kino's first launch in 2023 pitched "Silicon Valley meets Hollywood". By his own account it landed closer to Palantir for Hollywood: forward-deployed engineers running on-prem deployments for shows including Survivor and A24's Beef, inside Avid Media Composer environments and studio security rules that kept frontier models out of the building. The team rebuilt the product in 2025 around one bet, that editing should be code.

Agents in the wild

The launch post describes the maker's own workflow on the launch video: five-plus agents editing concurrently, one rotoscoping for visual effects, another color grading through Kino's LUT support, while two humans nudge the timeline. Filmmakers, he writes, run 15-plus agents against a single project with Kino as the source of truth. One founder quoted on the site ships ads daily: his agent finds licensed YouTube b-roll, cuts a spot, the co-founder leaves notes, the agent applies them.

The sliver is the claim: a first pass in a minute, from a testimonial on the vendor's own site.

The thread itself is a demo of the tempo. A commenter asked for eye-contact correction, the Descript party trick, and the founder shipped it into the build mid-thread: right-click a timeline item. Feature requests usually age for quarters in a backlog. This one outlived the comment section.

The bet: state as text

Handing an agent a conventional editor is like hiring a chef and then locking the kitchen: it can watch through the porthole and shout advice, but it never gets a pan. Kino makes the timeline a React project, so the agent reads and writes the same artifacts the editor renders, while the human keeps a normal NLE-style interface on top. Existing Remotion projects import directly and stay editable.

That design choice is the reusable idea if you build anything for agents. State that exists only as pixels cannot be operated on; state that exists as text, with stable addresses, can. Comments, review status, footage metadata and every timeline item are addressable documents, which is why a note can be routed to an agent with one click. The checklist generalizes: represent the work as text, give everything a URL, and let human and agent share one source of truth.

What it costs you

  • The full editor is free, including imports, exports, real-time collaboration and MCP access, with usage caps on agent calls.
  • Pro is $25 per editor per month, the founder's launch-post price: unlimited MCP tool calls, share links, more storage, YouTube search and team editing.
  • Model bills are separate. The pricing page is explicit that your AI provider's subscription and usage charges sit on top of whatever you pay Kino.
  • Camera originals stay on your machine and scrub locally, but Kino uploads a low-res proxy so teammates and cloud inference can see the footage. For NDA work, that upload is the line item to read twice.

Caveats

  • Adoption stories come from the launch post and the company's own testimonial wall. The 15-agent filmmaker and the one-minute rough cut are maker claims, not audited numbers.
  • The $25 price is the founder's statement; the pricing page confirms the tiers and the free-tier caps but renders its numbers in JavaScript.
  • Chrome-only web editing, and the desktop app is Electron. If your team lives in Safari or on a locked-down box, test before you migrate a project.
  • The field is crowding. Commenters in the thread name several other YC companies building agentic video tools, so expect churn.
  • Studio NLEs still own color pipelines, audio sweetening and twenty years of editor muscle memory. Kino is betting the agent changes the calculus before that matters.

Key Takeaways

  • Kino AI (YC S23) launched a collaborative video editor where Claude Code and Codex agents edit the same timeline as you, over MCP, with in-app chat, Grok Bot and Devin also supported.
  • Every edit is code on Remotion, and every project, clip, frame, comment and line of timeline code has a URL, which is what makes the agent an editor rather than a chat sidebar.
  • Camera originals (ProRes, DNxHD, Blackmagic RAW, RED R3D, OP-Atom MXF) play without transcoding, and footage is searchable on ingest by transcript, shot content and people.
  • Pricing: the editor is free with capped agent calls; Pro is $25 per editor per month for unlimited MCP tool calls. Your model provider's charges bill separately.
  • The product took three years to get here, through a 2023 on-prem era serving shows like Survivor and A24's Beef and a 2025 rebuild around code-first editing.
  • The pattern generalizes beyond video: represent the work as text, give everything a stable address, and let humans and agents share one source of truth.
