One image on your video.
A banner, a title, a logo, a lower third — composited onto the camera video you send in browser video calls. No account, no cloud, no subscription. Your video goes to your call — and nowhere else.
Joining someone else's call? It still works: the meeting is theirs, your camera is yours.
- No account
- No cloud processing
- Nothing uploaded
- Manifest V3
Your camera, whoever's call it is.
You don't need to be the host. Overlaysmith works on the video you send, so nobody else has to set anything up or allow it.
Their platform, your look
Every client runs their own platform, and every vendor runs another. Join their call in the browser and still show up with your name and title — no app to install for their platform, and nothing for the host to allow.
Your name on their stage
Invited to speak on a platform you don't normally use? Join in the browser with your own name, title and website on screen. The organiser doesn't have to set anything up. On Zoom, leave its blur and virtual backgrounds off — they cover the image.
Your name and title on the employer's platform
The interview is on whatever platform the employer uses. Join it in the browser with your name and the title you're going for on screen — nothing to install for their platform, nothing for the interviewer to set up. For an interview, $1.99 once removes the small mark.
Agenda and signs, switched mid-session
Put the session's agenda down the side of your video and move the highlight as you go, or put up a "Be right back" sign for the break. Switch images from the toolbar or a keyboard shortcut while you teach — no rejoining, and your shared screen is never touched.
Where it started
A campaign banner across the bottom of the game master's video, up all session like the screen on the table. That's what Overlaysmith was first built for, and it still does it.
Built by a game master. Tested on real calls.
I'm Terrance Henry, and I make Overlaysmith on my own. I run a superhero campaign that has met every session for two years with the same six players. When the group moved from a real table to video calls, I wanted the screen we used to sit behind across the bottom of my video. Google Hangouts once had an add-on for exactly that; when Hangouts went, nothing light replaced it, so I built one. The first image I tested it with was a photo of that screen.
Then it turned out to be more than a game tool. At my day job my company runs on Teams, and vendors invite me to their Zoom calls, which I join in the browser. One came up while I was still testing, and the preview showed my overlay was already live before I'd even joined. I switched it off and went in plain — but that's when it clicked: it doesn't matter whose call it is.
The rule I build it by: wherever the platform allows it, when Overlaysmith can't do its job properly it steps aside and sends your normal video. Losing your banner for a call is acceptable. Being left black, frozen or shown as an avatar is not.
Every platform in the list below went on it only after a real call with a second participant on another device. When something breaks, you email support@overlaysmith.com and I'm the one who answers. It launched in October 2026, so there are no store reviews yet — if you use it on a call, tell me how it went, or leave a review on the Chrome Web Store.

Three steps. The third one works mid-call.
Drop one in, type one, or describe one
Any transparent image — or one on a solid green background, which is removed for you — resized and re-encoded on your computer. No image yet? Type a title for a clean lower third, or copy a ready-made prompt for the AI image tool you already use. Nothing is uploaded anywhere.
Participants see it
The image goes onto the video you send. Your own tile stays clean (Zoom is the exception — see below), and screen sharing is never touched. A preview panel shows exactly what everyone else sees — and before the call starts, it lets you check your look without sending anything. Drag it anywhere on screen; it opens in the same spot next time.
From the toolbar or the keyboard
Change the image or turn it off while the call is running — from the toolbar icon, or step through your stage with a keyboard shortcut. No rejoining, no reconnecting.
Your stage, in your order.
A library of images is great until you need the right one mid-sentence. The popup shows only your stage — the images you picked for this call, in the order you set.
Only what this call needs
Put images on your stage and drag them into order. Everything else waits in your library, sorted and searchable — and any image in it is one click from going on the call, without joining the stage. Save a line-up under a name and load it for the next call like it.
Step through without looking
Shortcuts move to the next or previous image on your stage, or turn the overlay off and back on. They stop at the ends instead of wrapping round, and a small number on the toolbar icon shows where you are (pin Overlaysmith to your toolbar to see it). Change the keys in Chrome's shortcut settings.
One switch for the whole stage
Veil your whole stage — or your whole library — in one click on the library page. Veiled versions stay with their originals, and one switch in the popup puts every image on your stage into its veiled version, and back — including the one on your video right now.
Bring your own design, type one, or describe one.
Full-frame, and the transparency does the placing
Make a 16:9 image with transparency wherever your camera should show through — a lower third, a side strip, a corner logo, a frame, anything. There is no position setting because the image already says where everything goes. PNG, WebP, AVIF or GIF.
- Measured on import: size, format, how much of the frame it covers
- Warns if an image has no transparency or the wrong shape
- A solid green background is removed automatically
- Safe-zone guides show what survives phone and grid layouts
A title, a subtitle, a color
For when you want to look put-together and don't have a graphic. Type it, pick a color close to your brand, add it to your library. The text color is chosen for contrast automatically, and the size adapts so it fits on a phone screen.
- Sized to survive portrait phone layouts
- Warns — never blocks — if text is too long for phones
- Saved like any other image; make as many as you like
Prompt templates, placement built in
Pick a kind — lower third, sign, side panel or frame — and copy a prompt for the AI image tool you already use. Paste it, add what you want at the end, and bring the result back. The template tells the tool where things must go to survive the crop.
- Follow-up lines for when the first try needs adjusting
- Green-screen mode for tools that can't make transparency
- Just text you copy: the extension never contacts the tool
One image can be almost anything.
Each overlay was made from a prompt template and an AI image tool, then dropped in as an ordinary image. Shown as participants would see them, clean version. The people and rooms are AI-generated illustrations.
A side panel like the agenda sits outside the safe zone on purpose: it shows when you are in focus, and phones and small grid tiles cut it off. Switch images during the call to move the highlight down the list.
Hide your room without blur.
Background blur isn't always an option: it takes processing power, and on some platforms it slows your video or covers your image. Add a veil to any image in your library instead — a see-through layer over the sides of your video that fades out what's behind you, while the centre, where you sit, stays clear.
White or dark, soft or strong. Veil one image, your whole stage, or your whole library in one click. It makes a veiled version that stays with your original — one switch in the popup moves your whole stage between the two — and costs nothing extra during the call — no tracking, no added processing. It fades detail rather than blurring it, and it doesn't follow you: lean or gesture to the side and you go under it too. The person and room are an AI-generated illustration.
What it deliberately doesn't do.
Most webcam tools do fifteen things and need an account for all of them. This one puts one image on your video.
- No account. Install it and use it. No sign-in, no email, no profile.
- No cloud. Your camera is processed on your computer and goes nowhere except into your call.
- No recording. It doesn't capture, save or send your video anywhere.
- No AI in the extension. Nothing on your video is generated or analysed. The prompt templates are text you take to an AI tool yourself. Your platform's own blur and backgrounds still work alongside it; on Zoom they cover it — see below.
- No screen-share overlay. Shared screens are never touched.
- No side effects. Overlaysmith touches your camera video in calls, and nothing else. It runs only on the call sites listed below, plus any you choose to try it on, so every other site works exactly as before.
- No subscription. Free, or $1.99 once to remove the mark.
Browser video calls, tested one by one.
Every platform below was tested on a real call with a second participant on another device. Sites are added only once they pass.
| Platform | Status |
|---|---|
| Google Meet | Works, including effect changes and camera off and on mid-call. |
| Microsoft Teams (web) | Works, including effect changes mid-call. |
| Jitsi Meet | Works, including effect changes mid-call. |
| Whereby | Works. Heavy background effects can strain slower computers. |
| Yep | Works. |
| Webex (web) | Works, including effect changes mid-call. |
| GoTo Meeting (web) | Works, including effect changes mid-call. |
| Zoho Meeting (web) | Works, including effect changes mid-call. |
| Slack huddles (web) | Works. |
| Discord (web) | Works. |
| Zoom (web) | Works in the browser. Your own tile shows the image backwards (easy fix); participants see it correctly. Zoom's blur and backgrounds cover the image. |
| Desktop apps | Not supported. Overlaysmith works inside Chrome only — not the Zoom, Teams or Discord desktop apps. |
Google Chrome on a desktop or laptop. Chrome on phones doesn't run extensions.
Want your name and title on screen? The lower thirds guide covers Meet, Teams and Zoom step by step.
Platform not listed? You can try Overlaysmith on another site from the Sites tab in its popup. It's untested there, so it may or may not work.
Everything is free. The mark is the only difference.
Every feature. A small overlaysmith.com mark sits at the top of your video while an overlay is on. It's never shown when the overlay is off.
The same extension without the mark. One payment, no subscription, nothing to cancel.
Other webcam tools charge a monthly subscription to remove their watermark.
Paid securely through ExtensionPay (ExtPay), with card processing by Stripe. Reinstalling, or on another computer? Choose Already paid? Sign in in the popup and use the email you bought with — no new payment.
Your video goes to your call. Nowhere else.
Overlaysmith combines your camera and your image on your own computer, then hands the result to your call. We never receive your video, your images or anything about your calls — we have no servers for it to reach. There's no account, no analytics and no tracking. The extension's only network connection is to the payment service, to check whether you've bought the clean version — it carries nothing about your video, your images or your calls. The prompt templates are copied to your clipboard when you click; where you paste them is up to you.
