From the first take to the final export.

Start with the recording bar

Choose a screen, window, or area. Add your microphone and camera, then press Record. When the take is ready, open it in the editor to give it the finish it needs.

Automatic zoom

Kirocast makes your demos look cinematic, the moment you stop recording.

Smart auto-zoom

The moment you stop recording, Kirocast zooms in on the clicks and actions you performed on screen.

Advanced editing

Drag any zoom on the timeline, add your own, or adjust the easing. Trim, cut, and change the pace.

Smart annotations

Call attention to anything, without ever reaching for a drawing tool.

On the fly

Loop your cursor around something a few times while you record. Kirocast spots the gesture and draws the annotation in post.

Editing

Reposition, restyle, or remove any annotation. Full control whenever you want it.

Clean, custom backgrounds

Every recording lands on a background that looks designed, automatically.

Polished by default

Your capture sits on a tasteful background out of the box, so it looks professional with zero effort.

Real Mac wallpapers, or your own

Pick from real macOS wallpapers, drop in an image, or build a custom gradient.

Shadow, padding, and corners

Add depth with adjustable shadow, padding, and rounded corners.

Privacy masks

Not everything on your screen is meant for the audience.

Mask anything sensitive

Draw a blur over passwords, DMs, or any region on screen. Resize and reposition it right in the editor.

Never leaves your Mac

Masks are baked in on-device before export, so sensitive frames are never uploaded anywhere.

Automatic captions

Clear captions for every recording - transcribed on your Mac.

Transcribed on-device

Kirocast transcribes your audio locally with the Parakeet speech model. Nothing leaves your Mac. The language you speak is auto-detected as you transcribe.

Captions that keep up

Subtitles are burned into the preview and the export, highlighting each word as it’s spoken. Resize them to taste.

Yours to edit and export

Fix any word right in the editor, click a word to jump the playhead there, or export an .srt subtitle file.

Versions

Every edit you keep is a version you can go back to.

Saved as you work

The editor keeps your edits as numbered versions of the same recording, so a cut you liked yesterday is still there after a day of changing your mind.

Switch from the toolbar

The version picker sits beside the recording’s name. Step through them and the whole edit follows: the zooms, the background, the padding and the shadow all come back as they were.

Try the bolder cut

Take a version somewhere drastic knowing the one you had is a click away, so the safe edit is never the only one you ship.

Or let your agent do it for you

Give your agent a script. Through Kirocast’s MCP server, it can record, click, type, scroll, annotate, write timed captions, edit, and export a walkthrough.

The narrate tool adds timed text to captions and the transcript. It does not generate a spoken voiceover.

Review the result in Kirocast and ask for the changes it needs. You can also use Talk Mode to share a recording and its context with your agent.
