Features
Everything under the hood
Sixthly is built for business owners who wear every hat. Here is every feature, from real-time coaching to session replay.
Real-time coaching
AI coaching suggestions surface in a discreet sidebar during live meetings. Get prompts to ask sharper questions, reframe objections, bridge to value, and keep momentum — all without your counterpart noticing. Powered by Cialdini, Voss, and rapport-science frameworks.
On-device privacy
Your conversations never leave your machine. Sixthly uses Parakeet for local transcription and LanceDB for on-device vector search. No cloud uploads, no third-party access, no training on your data. Your meetings are your business.
Post-call debrief
After every call, receive an AI-generated meeting report with a concise summary, agreed action items, emotional trajectory graph, and a draft follow-up email ready to send in one click.
Contact intelligence
Evolving personas that improve with each interaction. Sixthly remembers communication style, past commitments, and rapport patterns so you walk into every meeting prepared.
Live rapport scoring
Six linguistic signals — mirroring, labeling, pace-matching, question ratio, affirmation rate, and interruption balance — scored and updated every 30 seconds during your call.
Expression detection
MediaPipe face mesh tracks visual engagement cues — eye contact, nodding, micro-expressions — giving you a real-time read on how the conversation is landing.
Knowledge base
RAG-powered retrieval across Cialdini's persuasion principles, Chris Voss's negotiation tactics, and rapport-science frameworks. Sixthly pulls the right technique at the right moment.
Multi-provider LLM
Choose Claude, GPT, or Gemini via OpenRouter using your own API key. Switch models per session or set a default. No vendor lock-in, no markup.
Session replay
Synchronized transcript, screenshots, and rapport timeline for every meeting. Scrub through the call to see exactly where momentum shifted and what coaching was surfaced.
Keyboard shortcuts
Global shortcuts for hands-free coaching control. Toggle the sidebar, pin a suggestion, mark an action item, or trigger a debrief — all without touching the mouse.
