Most things fix themselves in under a minute. Start here; if you're still stuck, the contact buttons at the bottom reach a human — the same one who built it.
Getting started
How do I use hindsight during a call?
Two ways. On the website: click Start camera, pick a delay, then hit Pop out — the floating window stays on top of every app, so park it near your webcam and join your call anywhere. With the extension: on Google Meet, Zoom (web), or Teams, click the hindsight icon and choose "Show mirror in this call" for a draggable mirror inside the call tab itself.
Why does it say "rewinding…" at first?
hindsight shows you the past, so it needs to record a few seconds of the present first — frames buffer in memory until there's enough history to play back your chosen delay. It resolves itself in exactly delay seconds.
Why is my image not flipped like in Zoom?
That's the point: call apps mirror your self-view like a bathroom mirror, but that's not what others see. hindsight is unmirrored by default so you see the truth. Toggle Mirror if you prefer the familiar flipped view.
Troubleshooting
The camera won't start
- Check the camera permission: click the icon left of the address bar and allow Camera for this site (or for the extension window).
- Another app may have locked the camera — quit other video apps and retry.
- The site needs HTTPS or localhost; opening
index.htmlstraight from disk won't get camera access.
The mirror freezes when I switch tabs
Browsers pause fully hidden tabs to save power. Keep the hindsight tab visible, or use Pop out — the floating window keeps everything running.
The overlay button says it can't reach the call tab
Reload the call tab once after installing or updating the extension — content scripts only attach to pages loaded after the install.
Picture-in-Picture won't open
PiP needs a recent Chrome or Edge. Firefox users: use the small floating window from the extension instead, or keep the tab in a narrow browser window beside your call.
Privacy questions
Is my camera feed recorded or uploaded anywhere?
No, and it can't be: frames live in memory for at most five seconds and are then discarded, and the extension holds no network permission — it is incapable of making network requests. Full details in the privacy policy, and the source is open if you'd rather verify than trust.
