I make Overlaysmith on my own. I build small browser tools and games that do one job, keep your data on your own computer, and need no account. I test each one on real use before it ships, and I answer the support email myself.
01 Why did I build Overlaysmith?
For my own game nights. 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 that, and nothing light replaced it when Hangouts went, so I built one.
At my day job I work on enterprise systems, which means a lot of calls on vendors' platforms. Joining one of those in the browser while I was still testing is how I learned the overlay doesn't need the host's permission: it works on whoever's call you're on.
02 How do I test it?
On real calls. A platform goes on the supported list only after a call with a second participant on another device, and every change to how video is handled is checked the same way before release. The rule I build by: wherever the platform allows it, when Overlaysmith can't do its job properly it steps aside and sends your normal video instead of breaking the call.
03 What else have I made?
- Skyline Architect — a browser game: drop blocks, build the blueprint, fight the wind. Launched March 2026.
- TrainScription — local AI transcription for any meeting app. No bot, no cloud. It came out of the same campaign. Launched June 2026.
- Ovrvue — a free, minimalist weather app built on what's actionable now. Launched August 2026.
- Overlaysmith — one image on your video in browser calls. On the Chrome Web Store since September 2026.
