The whole workspace,
as a desktop app.
Everything SmoothyEdit does — and everything a browser tab can't reach.
SmoothyDesktop runs the whole Smoothy workspace as a desktop app, then adds the heavy work a browser can't: on-device Whisper captions, hardware-accelerated transcoding, silence removal, and multicam auto-switch — plus a built-in bridge that pushes cuts, markers, and captions straight into Premiere Pro and DaVinci Resolve.
The app
One app. Four workspaces.
A real window on your desktop — sign in once and the entire Smoothy suite is there. Most of your day lives across four tabs.

Why it exists
The browser is a great place to start.
You paste a transcript and have shorts, hooks, and titles in seconds — before your editor is even open. But the tab hits a wall the moment the work gets heavy or touches your timeline.
It can't reach your timeline
A web app can hand you timestamps, but it can't drop a marker or a cut onto the sequence open in Premiere or Resolve.
Heavy work makes a round-trip
Captions, transcodes, and compression all have to upload, process on a server, and come back — metered and slow.
Your machine sits idle
The GPU and encoder in your computer do nothing, while you wait on someone else's queue and pay per minute.
What you get
Everything SmoothyEdit does.
Plus everything it couldn't.
Everything you already use
The full SmoothyEdit toolset — running locally
Paste a transcript and every SmoothyEdit tool is right there: find shorts, write hooks, generate titles and descriptions, plan thumbnails, suggest SFX and music, spin up a blog or a Twitter thread. Same models, same outputs, same account — plus your history, projects, AI Photos, and the Organizer. Nothing is left behind in the browser.
- Every AI tool, the same as the web app
- Your history, projects, and Organizer come too
- One sign-in — work syncs with your Smoothy account

The part a browser can't do
A bridge straight into Premiere Pro & Resolve
A built-in plugin opens a local connection to your editor over ws://127.0.0.1:3457. Shorts markers, multicam cuts, caption tracks, and chapter markers land on the exact timeline you're already cutting in — no export, no re-import, no copy-pasting timestamps. Both Premiere Pro and DaVinci Resolve are first-class destinations.
- Push markers, cuts, and captions to the active sequence
- Premiere Pro (UXP) and DaVinci Resolve, both first-class
- A backup sequence is saved before edits are applied

On your hardware
The heavy media work, at full speed
Because it runs on your machine, the expensive jobs happen on your hardware instead of someone else's server. Transcode and compress with the hardware encoder your GPU actually has — VideoToolbox, NVENC, AMF, or QuickSync — at multiples of realtime. Caption with whisper.cpp on-device, detect and trim silence, and auto-switch multicam by who's speaking.
- Hardware-accelerated HEVC — NVENC / VideoToolbox / AMF / QSV
- Local Whisper captions — no upload, no transcription credits
- Silence removal & multicam auto-switch, exported for your NLE
Hardware encoder
Encoding · 78% · 3.4× realtime on your GPU
The Tools tab
Seven tools the browser can't run.
On top of every SmoothyEdit feature, the desktop app adds a Tools tab — local media jobs and a direct line into your editor. Here's what each one does.
Compress
Batch-encode footage to HEVC using the hardware encoder your machine actually has — VideoToolbox, NVENC, AMF, or Quick Sync, with a CPU fallback. Pick High, Balanced, or Fast; it runs at multiples of realtime and shows the size saved on every file.
ffmpeg · hardware HEVC · .mp4
Silence
Scans a clip for dead air, then tunes the result by threshold, minimum gap, and padding. Export a Premiere-ready FCP7 XML — or, with Premiere connected, razor-cut and disable or ripple-delete the silent spans right on your timeline.
ffmpeg silencedetect · FCP7 XML
AI cuts
Transcribes locally with whisper.cpp, then uses AI to flag fillers, repeats, and retakes. Review each cut with its confidence, nudge the in/out by 100 ms, and apply straight to the active Premiere sequence — a backup sequence is saved first.
whisper.cpp + AI · Gentle / Standard / Aggressive
Chapters
Transcribes locally, then uses AI to find natural break points for YouTube-ready chapters. Edit the titles inline, then copy the formatted timestamp description or push the chapters as markers into your Premiere sequence.
whisper.cpp + AI · markers / YouTube description
Captions
Full on-device transcription with whisper.cpp models you download once (Tiny, Base, or Small). No upload, no transcription credits. Edit the transcript and word timing, style it, and export SRT / VTT / TXT — or burn the captions into the video.
whisper.cpp · SRT / VTT / TXT · burn-in
Multicam
Drop one audio file per camera; it detects who's talking on each track and builds a multicam sequence that cuts to the active speaker. Hold time, variation, and min/max shot length keep the cuts feeling human. Exports a Premiere FCP7 XML with a track per camera.

NLE bridge
A local WebSocket server the Premiere Pro UXP panel and DaVinci Resolve script connect to. It's the channel the other tools use to drop markers, cuts, caption tracks, and chapters onto the sequence you're already editing — no export, no re-import.

The workflow
From transcript to timeline, without the export.
Build the edit locally
Find shorts, generate a rough cut, caption, and compress — all on your machine, in one app.
The bridge connects to your NLE
The Premiere UXP panel or Resolve script links over a local WebSocket. The badge turns teal when it's live.
It lands on your timeline
Markers, cuts, and caption tracks drop onto the sequence you're editing — ready to refine, not retype.
Why running local matters
It changes the economics of every job.
Private by default
For local features, media never leaves your computer — built for client work, NDA footage, and unreleased projects.
No rate limits
On-device processing isn't throttled by a per-minute quota. Caption a hundred videos or one.
Full speed
Hardware acceleration means exports and transcodes run as fast as your machine allows — no round-trip.
Part of the Smoothy suite
How it fits with the others
Overlaps
- Includes every feature of SmoothyEdit — same AI tools, same outputs, same account.
- Hosts the Premiere Pro and DaVinci Resolve plugins — the bridge lives here.
- Imports SmoothyRec recordings directly as a multi-track project.
- Drops in SmoothyStudio titles as transparent PNG layers.
Not in this one
- —Designing titles and overlays from scratch — that workflow lives in SmoothyStudio.
- —Recording the original screen + camera footage — that's SmoothyRec's job.
Everything Smoothy, in one desktop app.
Every SmoothyEdit tool, the local-only features a browser can't offer, and a direct line into your editor — in one app. SmoothyDesktop is available now in beta, free with your Smoothy account.
