Klo

Klo is a native macOS video editor driven by an AI agent. Instead of hunting through menus and dragging clips by hand, you describe the edit in plain English, cut the dead air, caption it word by word, and Klo performs it on a real timeline in front of you. It's the conversational editing idea taken seriously, built as an actual Mac app rather than a web wrapper, with the agent operating the same timeline you could touch yourself.

That last part matters more than it sounds. Plenty of AI video products are black boxes, you upload footage, wait, and get a rendered file back with no way to see or adjust what happened. Klo keeps the timeline at the center. The agent's edits land as real timeline operations, so you can inspect what it did, refine it with another instruction, or take over manually. The conversation is the input method, not a replacement for the edit itself. That workflow also degrades gracefully. When the agent gets an instruction slightly wrong, you're not waiting on a new render from scratch, you're looking at a timeline where the mistake is visible and correctable, either with a follow-up sentence or your own hands. The examples the site leads with are mundane on purpose, cutting dead air and word-by-word captions are the chores every editor knows too well.

The toolset is broad for a young product. Klo ships 83 editing tools covering cutting, color grading, and word-by-word captioning, plus generated music and generated voiceover, so a rough screen recording can pick up a soundtrack and narration without leaving the app. It handles beat-synced cuts for footage that needs to move with the music, and native motion graphics for titles and overlays. When you're done, it exports H.264, HEVC, or ProRes 422 at up to 4K, which covers everything from a quick social clip to footage headed into a bigger post pipeline. Processing happens locally on your Mac. The grading and captioning tools cover the finishing work that usually pushes people out of a quick trimmer and into a full editing suite, which is the gap Klo is clearly aiming to close.

The unusual feature is the MCP server. Klo exposes its timeline through the Model Context Protocol, which means coding agents like Claude Code, Codex, or Cursor can drive the editor programmatically. If you already live in an agent-driven workflow, you can script video production the same way you script everything else, with the agent issuing timeline operations to a real native editor instead of shelling out to ffmpeg and hoping. That makes Klo interesting to developers and automation-minded creators, not just editors. It opens the door to workflows where an agent assembles a rough cut or batches out exports while you supervise the result from inside the app.

The core audience is content creators who produce regularly and feel the grind of repetitive editing, cutting silence, adding captions, syncing to music, exporting variants. Those are exactly the tasks that are easy to describe in a sentence and tedious to do by hand, which is the sweet spot for a conversational editor. It runs on macOS 13 or later and supports both Apple silicon and Intel Macs, so it isn't limited to the newest hardware. Podcasters clipping episodes, course creators captioning lessons, and indie developers cutting demo videos all fit the pattern, frequent output, similar edits every time, and limited appetite for timeline fiddling.

What sets Klo apart from the wave of AI video tools is the combination of native, local, and agentic. It's a real Mac app doing its processing on your machine rather than a browser front end for a render farm, and it's built agent-first, from the plain-English interface down to the MCP server that lets outside agents operate it. Few products in this space check all three of those boxes at once.

Local processing has practical upsides beyond privacy too. Your footage doesn't need to be uploaded before work can start, which matters when source files run to many gigabytes, and the app keeps working regardless of what's happening to anyone's render farm. The ProRes 422 export in particular signals that Klo expects to hand footage into serious post pipelines, not just push compressed clips to social platforms.

Pricing is freemium and metered by asks, the plain-English requests you make of the agent. The free tier includes 10 asks so you can feel out whether talking to an editor suits you. Pro runs $30 a month with 50 asks, and Studio runs $200 a month with 300, aimed at heavier production schedules. The asks model means you're paying for agent work rather than seat time, so manual timeline work doesn't burn through your quota. For anyone curious whether conversational editing is real yet, the free tier is a low-friction way to find out.
