What is Respond.io?
respond.io made AI ambient across the platform and metered it in the same fortnight.
Copilot now sits in every workspace: it answers product questions from the Help Center, navigates to any module without leaving the current one, and drafts a full AI Agent from a description then runs test cases against the draft before it goes live. Separately, AI Credit On-Demand starts billing AI usage past a plan's included credits automatically from the next cycle. The rest of the window is inbox and channel work — a Cmd+K command palette, a Calendly integration, conversations opened from Instagram Story mentions, and a configurable wait so an agent hears a full multi-message thought before replying.
What is Heymarket?
Real features ship between the SEO posts: tags, webhooks, escalations, and now RCS via Twilio.
Heymarket's feed is a marketing blog with product announcements mixed in at roughly one post in three. The genuine releases in this window are Escalations, which pushes an unanswered conversation to a named person, and enablement for RCS campaigns through Twilio. The rest — a conversational-AI definition, a healthcare AI buying guide, email-writing advice — is search content with no product change behind it.

◆ Current state
Copilot now sits in every workspace: it answers product questions from the Help Center, navigates to any module without leaving the current one, and drafts a full AI Agent from a description then runs test cases against the draft before it goes live. Separately, AI Credit On-Demand starts billing AI usage past a plan's included credits automatically from the next cycle. The rest of the window is inbox and channel work — a Cmd+K command palette, a Calendly integration, conversations opened from Instagram Story mentions, and a configurable wait so an agent hears a full multi-message thought before replying.
◆ Where it's heading
The two AI releases are one decision seen from both ends. respond.io is making AI the default way to operate the product, including building the agents themselves, and at the same time converting AI from a capped plan feature into a metered consumable that cannot run out mid-workflow. Copilot's grounding rule — it says so when the docs do not cover a question — indicates they expect it to carry real support load rather than demo well.
◆ Prediction
With agent creation and overage billing both in place, usage governance is the gap: per-team credit limits or reporting that shows an admin which agents consume the budget.

Real features ship between the SEO posts: tags, webhooks, escalations, and now RCS via Twilio.
◆ Current state
Heymarket's feed is a marketing blog with product announcements mixed in at roughly one post in three. The genuine releases in this window are Escalations, which pushes an unanswered conversation to a named person, and enablement for RCS campaigns through Twilio. The rest — a conversational-AI definition, a healthcare AI buying guide, email-writing advice — is search content with no product change behind it.
◆ Where it's heading
The product work visible here is all about absorbing volume: tags to structure conversations, inbound webhooks to pull in the rest of the stack, escalations to catch what nobody answered, and AI agents the team says it trained against its own inbox first. Heymarket is building the operations layer around business messaging rather than extending the messaging surface itself. Channel breadth is arriving through partners, with RCS riding Twilio rather than native carrier work.
◆ Prediction
The next release is most likely another triage or routing control, since escalations and conversation tags both point that way. Entry bodies in this feed are truncated excerpts, so how far the AI agent work has actually gone is not visible here.
