Customer experience
From an SMS reminder to a full AI Voice Agent — built once, run everywhere.
Design call flows in low-code. Trigger them on any event in your stack. Branch on caller intent, route to the right agent, escalate to a human when it matters — all running serverless on Callr’s infrastructure.
- Build flows in hours, not months — in low-code.
- Branch, route, transcribe, summarise.
- Plug any LLM — yours or ours.

Sales enablement
Make every call your sales team takes more profitable.
Qualify the caller before the rep picks up. Whisper the context as the call connects. Push the AI summary into the CRM the moment the call ends. Less manual logging, fewer dropped follow-ups, more closed deals.
- Qualify and enrich callers with AI Agents
- Auto-update your CRM after every call
- Analyse every interaction with AI
- Track team performance, call by call

Data Intelligence
What if every phone call was as measurable as a click?

- Generate transcripts and recaps in seconds
- Extract sentiment, intent, and satisfaction
- Auto-enrich your CRM and analytics
Voice AI
Bring your own model. Or use ours.
