What's on my calendar tomorrow?
Based on your previous preferences, I know you like to block mornings for deep work. Tomorrow you have a team standup at 10am — same as every Tuesday. Want me to check if Sarah is free in the afternoon?
Yes, schedule 30 minutes with Sarah at 3pm
Done! Created 'Sync with Sarah' at 3:00–3:30 PM. I added your usual Zoom link and tagged it as a 1:1. I also remembered she prefers shorter meetings, so I kept it to 30 min.

Everything You Need
A complete platform for building intelligent voice applications — from raw audio to structured memory.
Realtime Voice
Sub-200ms latency with OpenAI Realtime API and Google Gemini Live. Switch providers mid-conversation without dropping the session.
Persistent Memory
Semantic search over conversation history. The AI recalls relevant facts, preferences, and context from every past interaction.

CTO at BuildFast since 2021, team of 12 engineers
Follow up on Q2 roadmap proposal
Context Injection
Before each call, VoiceAI bundles your memories, documents, and integration state into the context window automatically.
→ injecting 4,200 tokens of context
MCP Tools
Connect Gmail, Slack, Calendar, Jira, CRM, and more. The AI can take action mid-conversation.
BYOK Support
Bring your own OpenAI or Gemini API keys. Zero margin on tokens — pay providers directly at cost.

Post-Call AI
Every call generates summaries, action items, and extracts memories automatically. Nothing falls through the cracks.

How VoiceAI Works
Three steps from sign-up to your first intelligent voice session.
Configure
Add your API keys, connect MCP integrations, and set up your workspace in minutes. One-click authorization for all major tools.
Supports OpenAI, Gemini, and any OpenAI-compatible provider.
Workspace Settings
Call
Start a voice session. VoiceAI automatically injects your memories and context, then connects your tools — you just talk.
Sub-200ms latency. Works in browser, mobile, or via API.
→ 5 memories injected, 3 tools active
Remember
After every call, AI extracts memories, generates summaries, creates action items, and prepares full context for your next session.
Fully automatic. Nothing to configure after setup.
Post-call processing
Your AI That Actually Remembers
Every conversation is automatically processed to extract memories — facts, preferences, tasks, and relationships. These are stored as semantic vectors and retrieved before every call, so your AI always has full context.
- Automatic extraction after every call
- Deduplication with semantic similarity
- Importance scoring (0.0 – 1.0)
- GDPR-compliant deletion on request
- Cross-session continuity and recall

Schedule a meeting with Sarah for tomorrow at 2pm
Done! I've scheduled 'Meeting with Sarah' for tomorrow at 2:00 PM. I also added it to the shared team calendar.
The AI took two sequential actions mid-conversation — no interruptions.
