screentell is a in-browser screen recorder for fast product demos, tutorials, and social clips
Screentell is a browser-based screen recording and editing tool for fast product demos, tutorials, and social clips—no software install, just record, edit, and export in minutes.
Screentell, and the idea is:
A low-friction, in-browser screen recorder + editor that covers ~90% of “I just need a decent demo” use cases.
No install, no desktop app, just browser.
What it does (and why I built it this way)
Recording
I wanted to hit “record” and not think too much:
record screen + camera at the same time
capture both system audio and mic (so you can narrate while playing app sounds / videos)
Editing (directly in the browser)
Most of my edits are very “presentation-like”, not full video production. So I focused on:
Cropping the screen – hide browser tabs, taskbar, or any sensitive stuff, and just keep the content region that matters.
Smooth zoom / focus – simple “zoom into this part” so viewers know exactly where to look.
Stickers & callouts
I always end up wanting arrows and little annotations, so I added:
Hand-drawn style stickers – arrows, underlines, speech bubbles, shapes, text, images, etc.
The goal is to quickly highlight “click here”, “this changed”, or “this is the important part” without opening a full-blown editor.
Layout / presentation
I also care about how the final frame looks (especially for posting on social media):
choose a background (solid color, gradient, or wallpaper)
put the screen recording in a kind of “card” with padding + shadow
treat the face camera layer as a movable/resizable element: show/hide it, change size/shape/position
Basically: make the final video look like something you’d be okay dropping into a landing page, tweet, or product update — without touching Premiere / Final Cut.
Who it’s for (roughly)
If you’re:
recording product demos
making short tutorials / onboarding clips
creating quick social content around your app or workflow
…and you don’t want to install heavy software or learn a complex timeline editor, this might be useful.
There’s no software to download, everything is done in the browser (record → edit → export). Most people should be able to figure it out in a few minutes of clicking around.
Right now it’s very much built from my own pain points as a solo dev who constantly needs “yet another demo,” so I’m sure my blind spots are showing.
If you do screen recordings often, I’d love to know:
What’s the most annoying part of your current workflow?
What’s the one thing your current tool still doesn’t do well?
