Ask about your calls, then have it follow up.

Connect Fast Response to Claude or ChatGPT and ask in plain English about every call, text and chat, the AI's and your team's alike. Then have it act: text a customer, add a note, set a reminder. It shows you every text before it goes out and links you straight to each conversation.

Hi, I'd like to get someone out to look at a leaking faucet this week.
I can book that now. We have Tuesday at 10 AM or Wednesday at 2 PM. Which works?

Zapier, Make, n8n and webhooks

Every call, text and chat, AI or human, in the apps you already use.

Fast Response is your business line, so the calls your team takes and the ones the AI handles land in the same stream. Every one comes with a summary, transcript and outcome, and any of them can start an automation that sends it on to Zapier, Make, n8n or any URL.

Attach a private or public call link, plus custom fields
API: contacts, notes, tasks, lists, with API keys or OAuth2
