KailaOS - Walk Into Every Meeting Ready - The AI assistant that preps you for every meeting

Hey Product Hunt 👋 I built Kaila because I kept walking into meetings half-prepped. Investor calls where I forgot the latest metric. Client check-ins where I winged the agenda. Interviews where I had the right answer 20 minutes too late, in the shower. The existing tools didn't help. Calendar apps tell you when the meeting is. Note apps store what happened. Nothing actually got me ready for what was about to happen - and nothing did it by voice, which is how I think when I'm walking, driving, or pacing before a call. So Kaila is a voice-first AI chief of staff. Three things make it different: 🎯 Meeting prep that comes to you - Kaila scores your upcoming meetings based on stakes and complexity, then proactively pings you 30 minutes before the high-stakes ones: "Board Review in 30 - want a quick prep?" You get talking points, likely questions, and risks to watch for. 🎤 Rehearsal mode - Practice the actual conversation with an AI playing the other side: investor, interviewer, client, board member. 5 difficulty levels from warm-up to intense cross-examination. Every answer scored 1–10 across six dimensions: clarity, specificity, brevity, credibility, objection handling, executive presence. The part I'm proudest of: it remembers your weak spots across sessions and pushes you on them next time. 🗣️ One unified system, all by voice - Calendar, tasks, projects, notes, contacts, reminders, lists, files, web search, email. Everything connects: notes link to events, files attach to projects, contacts attend meetings. The thing that surprised me most while building it: rehearsal went from "nice-to-have" to the part power users open daily. Turns out we don't lack information before meetings - we lack reps.
