Side Quest Hotline Vapi Hackathon

CrossTalk is a phone hotline where two people who don't share a language just talk, each in their own, and hear the other translated in about a second, built on Vapi, Deepgram, TypeSafe Jev and Exa.

Outbound AI call centers for Masky avatars: give the agent a goal, it finds matching people with Exa, phone-calls them in the avatar's own cloned voice over Vapi/Twilio, walks them through a human-authored step-by-step script — and after every single thing the callee says, a calibrated TypeSafe probability judge (Jev, not an LLM) re-scores the odds the call will still reach its goal and gracefully ends it the moment that drops below 5%.

Unspokn is an AI-powered communication app that translates silent lip movements into text or natural-sounding speech, giving everyone a way to communicate without making a sound.

Its an ai chief of staff to monitor everything you need and call you when something in important

Laptop Closed is a voice agent: when you shut your laptop lid, your phone rings (via Vapi, with Deepgram for speech) and you keep working by voice, with Exa doing research, Manus building things in the cloud, and Jev deciding when a finished task is worth calling you back.

Tell me where you want to go by phone, I tell you if you should drive or take public transportation.

CallLens shows which turn of a Vapi voice call broke and why (latency by stage, mishearing, dead air), judged by TypeSafe Jev in ~120 ms, and self-heals the live agent in one click. Demo agent: Side Quest Hotline (Vapi + Deepgram + Exa + Jev).
