Speaker Copilot
Paces a live talk with vibration cues, so you're never guessing how much time is left.
Speaker Copilot splits a talk into timed sections that advance automatically on stage, with a short vibration marking each transition and a 30-second warning before one ends. It also holds rehearsal scoring across five criteria, plus clue cards, SOS phrases, and Q&A scaffolds for when something goes wrong mid-talk. It's free, open source, needs no login, works offline as a PWA, and keeps all data in the browser's local storage so a talk never leaves the device.
What holds up
- +Free and open source, with the code on GitHub — nothing to buy or subscribe to.
- +Works fully offline as an installed PWA — no login, and conference Wi-Fi isn't a dependency.
- +Rescales section timings automatically if you change the total time, so nothing gets redone by hand.
Mind the limits
- −Built and maintained by one non-developer as a side project, so support and updates aren't guaranteed.
- −Ships only as a browser-installed PWA — there's no dedicated app-store listing.
