Is InstantReply cheaper than Respond.io?
At the entry tier, yes: $59/mo ($49.17/mo annual) against Respond.io's $79/mo annual rate, though Respond.io includes 5 users where InstantReply Starter includes 1.

Respond.io Growth and Advanced bill $12 or $15 per extra 100 Monthly Active Contacts past 1,000; InstantReply has unlimited contacts and no per-contact fees, with AI replies capped at 10,000 / 35,000 / 100,000 a month.

Does InstantReply have AI Agents like Respond.io?
Both handle voice and images. Respond.io's AI Agents on Growth and higher can analyze images and files and transcribe incoming audio, so it isn't accurate to call them text-only. The difference is packaging: InstantReply's voice transcription, image understanding, and calendar booking are in the base plan-based AI, while Respond.io's autonomous AI Agents are a Growth-and-up feature layered on top of Starter's AI Assist and Prompt.
Can I migrate from Respond.io to InstantReply without losing history?
