What is Respond.io?
WhatsApp-first inbox teaching its AI agents conversational patience — and losing the phone number as identity.
respond.io ships steadily against two tracks. The AI Agent track has been fixing the ways an agent behaves unlike a person: it can now wait up to five minutes for a Contact to finish typing before replying, send files and images as rendered attachments instead of bare links, recognize when it has been assigned a conversation or when a closed one reopens, and the Voice AI Agent got lower latency and more reliable reasoning. The channel track follows Meta's platform: WhatsApp carousel templates carrying 2–10 product cards, and support for WhatsApp usernames and Business-Scoped User IDs.
What is Front?
Front is spending its AI budget on control — which facts, which sources, which answers.
Front publishes a monthly digest plus individual item posts, and the last three months read as one continuous project: making the AI in the inbox auditable. Admins can connect Guru and Confluence as knowledge sources and see exactly which articles were included, excluded, and why; upload their own files as knowledge; and invalidate individual facts an AI reply drew from stale conversations. Around that sit channel and client work — a redesigned mobile app, AI Translate across SMS, WhatsApp, Messenger and chat, and a run of partner integrations.

Respond.io
6.3COMMSSUPPORT
WhatsApp-first inbox teaching its AI agents conversational patience — and losing the phone number as identity.
◆ Current state
respond.io ships steadily against two tracks. The AI Agent track has been fixing the ways an agent behaves unlike a person: it can now wait up to five minutes for a Contact to finish typing before replying, send files and images as rendered attachments instead of bare links, recognize when it has been assigned a conversation or when a closed one reopens, and the Voice AI Agent got lower latency and more reliable reasoning. The channel track follows Meta's platform: WhatsApp carousel templates carrying 2–10 product cards, and support for WhatsApp usernames and Business-Scoped User IDs.
◆ Where it's heading
The AI work has moved past capability and into etiquette — the recent releases are all about an agent knowing when to speak, what to attach, and where it sits in a handoff, which is the difference between a bot customers tolerate and one they do not notice. Underneath it, the identity model is being rebuilt: WhatsApp usernames mean the phone number stops being the primary key, and respond.io has already threaded BSUIDs through Contact matching, templates, webhooks, and the Developer API.
◆ Prediction
With wait time, attachments, and assignment awareness in place, the next agent work likely targets the handoff itself — how an AI Agent escalates to or resumes from a human — while channel work keeps tracking WhatsApp's identity and commerce surfaces.
Front
2.5SUPPORTCOLLAB
Front is spending its AI budget on control — which facts, which sources, which answers.
◆ Current state
Front publishes a monthly digest plus individual item posts, and the last three months read as one continuous project: making the AI in the inbox auditable. Admins can connect Guru and Confluence as knowledge sources and see exactly which articles were included, excluded, and why; upload their own files as knowledge; and invalidate individual facts an AI reply drew from stale conversations. Around that sit channel and client work — a redesigned mobile app, AI Translate across SMS, WhatsApp, Messenger and chat, and a run of partner integrations.
◆ Where it's heading
The interesting choice is that Front is investing in governing what its AI knows rather than expanding what it can do. Fact-level invalidation with strikethrough and re-enable, sync visibility with reasons for exclusion, and admin-selected sources are all answers to the same objection: support leads will not turn on automated replies they cannot audit. The integration track runs in parallel and widens the surface instead — Zoom Contact Center brings voice and SMS into the same inbox, and the One integration makes Front data reachable from an outside agent runtime.
◆ Prediction
With sources and fact-level controls in place, the missing piece is measurement of the AI itself; analytics is already a recurring monthly theme, so reply-quality or deflection reporting is the natural next release. The early-access track flagged in June should also surface as named features.
