Postloom · Other
Postloom is a browser-based app demo video editor that turns any screen recording into a finished product demo. As a phone mockup video editor, it lets you drop in a recording, wrap it in a device frame, then add zooms, click effects, captions and arrows on a real timeline you can still change. Think of it as an app demo maker for people who ship demos often but don't want to learn a full video suite.
About Postloom
What Is Postloom
Postloom is a browser video editor built around one job: making app demo videos from screen recordings. Instead of starting from a blank timeline, you feed it a recording of your app, pick a device frame and a style, and the tool handles the framing while you refine timing and effects.
The problem it solves is the gap between a messy screen recording and a demo that looks intentional, the kind of clip you'd happily put on a landing page or an app store listing. Most people record their phone or desktop, then struggle to make it presentable. Postloom keeps the recording but gives it a clean phone mockup, smooth zooms and on-screen cues. The path from screen recording to app demo stays short because you're refining a clip, not building one.
The main limit is scope. It edits demo-style clips, not feature films, so multi-cam work and heavy color grading aren't the point here. Media also stays on your machine, which is good for privacy but means a browser tab is doing the heavy lifting. So what does it replace? Mostly the awkward middle step between recording and publishing.
Getting Started
- Open the editor in your browser and sign in, or start editing for free before you pick a plan.
- Drop a screen recording or screenshots onto the media panel and drag the clip onto the video track.
- Choose a device frame and background, then trim the clip to the part that matters.
- Add zooms, click effects, captions, arrows or blur areas on the timeline.
- Export as MP4 or GIF; watermarked-free exports need a paid plan.

Key features
Screen Recording to Framed Demo
Postloom's core move is taking a plain screen recording and placing it inside a phone mockup with a background. You don't rebuild the demo by hand. The recording stays the source and the frame does the presentation work. That's the whole trick. It's the difference between a screencast and something that looks like a real product demo.
Timeline Editing You Can Revisit
This isn't a one-click generator that locks in a result. Zooms, clicks, captions, arrows and blur areas all live on a timeline you can drag and re-time later. Project files reopen on paid plans, so a demo made last month is still editable today. No re-recording needed.
Click and Zoom Cues
You can highlight the exact moment a user taps a button or swipes a screen, which is where most demos lose viewers. Zoom ranges and click markers sit on separate tracks. A fast tap sequence stays readable instead of flashing past in one second. Simple, but it matters.
Captions, Arrows and Blur
Text captions, arrows and blur areas cover the usual fixes: labeling a feature, pointing at a control, or hiding a real email that appeared in the recording. They behave like timeline objects, not baked-in edits. You can move or delete any of them.
Local Media Processing
Media stays in your browser, and nothing is uploaded while you edit. For teams handling unreleased features or customer data, that removes an awkward step. It also means a decent machine and browser matter for longer clips. Fair trade.
Video and GIF Export
Every plan exports both MP4 video and GIF, and every export is clean with no watermark. GIFs are handy for help centers and pull requests where a video feels heavy, and videos fit landing pages and social feeds. For a quick demo video generator, this two-format export covers most places a clip needs to go.
Team Seats and Shared Projects
Any plan can add teammates for $5 per month each. The Unlimited tier adds team seats outright. Small product teams get one shared home for demo projects. That's a nice fit.
Pros and cons
Pros
- Built specifically for app demos, so you skip the steep learning curve of a general video editor.
- Timeline-based editing keeps projects reopenable and changes non-destructive.
- Media stays local in the browser, which helps when recordings show unreleased or private data.
- Every plan exports MP4 and GIF with no watermark, and editing itself is free before you pay.
Cons
- Exporting, saving projects and team access all require a paid plan, so free use is really just a trial.
- No API means you can't wire demo generation into a build or content pipeline.
- It's tuned for demo-style clips, so anything needing multi-cam or advanced grading is out of scope.
- Browser-only, so long or high-resolution recordings lean on your own machine's power.
