Record. Edit. Review. Deliver. In your browser.

All creative work
in one place.

Aperture is a browser-native studio with a full library behind it: record screen and camera, upload, or drop files in a watch folder — every word transcribed and searchable. Find the moment, click it, cut on a real timeline. No installs, no round-trips. Any device, anywhere in the world, any time.

Drop two videos. Get three edits.

The homepage is the product. Drop two clips below — we merge them into three finished cuts (dissolve, slide, circle) and play them right here. Watch as much as you like. Create a free account and all three land in your library, ready to download or keep cutting.

MCP · Model Context Protocol

Your AI agent
can already edit video.

Aperture ships with a working MCP server. Point Claude Desktop, Cursor, Codex or any MCP client at it and the agent gets 14 live tools against the real platform: search every word ever spoken, upload and transcribe footage, run the free tools, render sequences, export platform kits, publish to YouTube — through your API token, with full audit trail. No integrations team. One JSON snippet.

  • 14 tools — library, semantic transcript search, upload, transcribe, render, export kits, YouTube publish, the 15-tool free engine, raw API passthrough
  • Token auth — the agent inherits your tenant, rate limits and audit trail; revoke anytime
  • Stdio MCP — the open Model Context Protocol standard, works with every MCP client

The Aperture platform

Whatever you create, Aperture helps you deliver it faster.

One workspace runs the whole pipeline — editing, review, and delivery — because the timeline, the transcript, and the library live together.

A Real Browser NLE

Multi-lane timeline with transitions, position keyframes, speed ramps, transforms, and titles — previewed in your browser, conformed by the server.

Timecoded Review

Threaded comments anchored to the frame, with resolve states and @mentions. Guests review through secure links.

Library & Stock

Collections, smart collections, and tags keep assets findable; Pixabay, Pexels, and Wikimedia are built in.

Share & Deliver

Guest viewers with expiry, password, and PREVIEW watermark — then 16:9 / 9:16 / 1:1 presets, GIF, per-lane stems, and −14 LUFS delivery.

Remove blockers from ingest to delivery.

Organize everything

Collections and smart (saved-search) collections, tags with bulk operations, and duplicate detection — the library stays findable as it grows.

Connect everyone

Timecoded threads with replies, resolve, and @mentions follow the work. Internal notes stay separate from guest conversations.

Move faster

Text-based editing, one-click silence and filler removal, and moment search that opens the timeline exactly where you need it.

Why Aperture

Five things the other tabs can't do.

Search lands inside the cut

Search any word ever spoken in your library. Click the result — the editor opens at that second, sequence loaded, playhead ready. Nobody else puts the search result inside the editor.

Preview is the render

Browser preview and server conform run the same edit vocabulary — fades, transitions, keyframes, karaoke captions, stems. What you see is the file you get.

Two editors, one timeline

Realtime co-editing with live presence — names, colors, playheads — in a browser tab. Not comments about a video. The actual timeline, together.

Delivery that clears QC

−14 LUFS loudness normalization, per-lane stems, 9:16 / 1:1 / 16:9 presets, GIF, watermark burn-in — and EDL, FCPXML, OTIO when the color suite calls.

The pipeline is an API

Tokens, signed webhooks, rules, audit trail, usage metering. Every UI action has a REST path — automate the boring 80 percent.

New · the recorder

Open a tab. Start talking.

Screen, camera, and mic in one browser take — with layers mode: the camera is saved as a separate track, so your take opens in the editor as screen lane + camera lane + audio, re-layoutable after recording. Chunks upload while you record; word-level transcription starts the moment you stop.

Open the Recorder How layers work

Find any moment by what was said — not by scrubbing.

See Moment Search

A moment for the fallen

The workstation had a good run.

1985 – 2026. It rendered, re-rendered, and always asked for more RAM. Your edit now lives in a tab — and the tab goes where you go.

Open your browser

Five minutes change everything

Any device. Anywhere in the world. Any time.

The workstation is gone. Your edit is a tab — and dead time becomes work.

5 free minutes at the gate? Make changes.

Open the sequence on your phone, cut two sentences from the transcript, autosave, send a review link. Board the plane with the cut done.

Work anywhere

Waiting at taekwondo lessons? Make cuts.

Kids train for 40 minutes; a nice teaser takes 12. Trim on the tablet between belt ceremonies — the server renders, not your laptop.

The five-minute stories

Perfect TikTok ads? The perfect place to start.

LLM-ranked hooks from your master, 9:16 reframe preset, auto-captions in safe zones, music that ducks under the pitch. A week of ads from one edit.

Library

Upload, organize, and find everything with ease.

Explore the Library
  • Collections & smart collections

    Folders plus saved searches that update themselves. Drag assets in, filter by kind, share tenant-wide.

  • Tags & bulk operations

    Shift-select across the grid, then bulk tag, favorite, collect, or delete. Filter chips keep views clean.

  • Stock built in

    Search Pixabay, Pexels, and Wikimedia Commons. Import runs the real ingest pipeline — storage, proxies, catalog.

Review & editing

Edit at the speed of text. Review at the speed of thought.

The transcript and the timeline live in one engine.

Select words in the transcript to razor and ripple the timeline. Cut sentences, fillers, and silences in one click — undo-safe, everywhere.

  • Threaded review

    Replies, resolve states, and @mentions on timecoded comments — decisions stay attached to the asset.

  • Versions & compare

    Upload new versions, keep the stack, and review side-by-side before anyone signs off.

  • Auto-captions & titles

    Captions from the transcript, styled burn-in at export, and a text track for lower thirds.

Every guest link ships with expiry, password, and watermark.

See Share Links

Share & deliver

Share securely, review easily, deliver beautifully.

See Review & Share
Share securely

Guest links with expiry dates, optional passwords, and view counts. Revoke access any time.

Watermarked previews

Public viewers carry a PREVIEW watermark — real feedback without loose copies in the wild.

Deliver anywhere

Export presets for 16:9, 9:16, and 1:1 reframe, plus audio-only — masters render on the server.

See how teams run their pipeline in Aperture.

60-minute rough cut to same-day publish

Text-based editing and one-click filler removal turned the transcript into the edit.

Client rounds drop from five to two

Timecoded threads and guest review links replaced email chains and file-transfer ping-pong.

See review & approve

One master edit becomes ten shorts

LLM highlight ideas and the 9:16 reframe preset feed every channel from one timeline.
