Teams use a documented REST API, webhooks and a low-code flow builder to embed click-to-call, SMS notifications, IVR menus and AI voice agents directly into their own products — no telecom expertise or hardware required, because the platform runs serverless on infrastructure Callr operates itself. The differentiator is what happens after the call connects. Every conversation can be transcribed, summarized and enriched with sentiment, intent, satisfaction and campaign attribution, then pushed automatically into Salesforce, HubSpot, Google Analytics, Google Ads or a BI stack. Because the AI layer is model-agnostic, customers can plug in GPT, Claude, Mistral, Llama or their own in-house LLM and define the extraction prompts themselves. A second mode covers calls nobody picks up: AI voice agents built in the low-code flow designer answer after hours or on overflow, qualify callers, book appointments and hand off to a human with full context. According to the company, the platform handles around 2.5 million calls a day for more than 300 businesses across marketplaces, real estate, automotive and agencies, with per-interaction economics published as roughly €0.012 per voice interaction. **Pricing & Plans:** Free trial available; paid usage-based plans. The site lists the option to get started for free and a pricing page; per-interaction figures published by the vendor are around €0.012 for voice, €0.040 for SMS and €0.001 for email.
