Kapture argues the agentic-CX case in public while its actual shipping stays off the feed.
Kapture sells AI customer-service software, but the crawled feed is its editorial blog rather than a release stream. The recent posts are market-argument pieces — enterprises hedging with multi-model AI stacks after a vendor deprecated models on two months' notice, why autonomous AI service still needs a human handoff, the case against token-based pricing, and a piece on companies rehiring roles they cut for AI. Rounding it out are an event post and a Croma customer case study.
respond.io is layering an agent-authoring copilot and consumption billing on top of its omnichannel inbox.
respond.io ships something visible every few days across three fronts: channel coverage, the agent-facing inbox, and AI. Microsoft 365 and Outlook joined as a full email channel with workflow routing and reports, Calendly arrived as an integration, and Instagram Story mentions can now open conversations automatically. The inbox itself picked up a Cmd+K command palette, drag-out full-size image saving, and browser-tab unread signalling, while the mobile app gained offline message queuing.

The writing is building a position rather than reporting releases: AI service should be model-agnostic, priced by outcome rather than tokens, and designed with a human escalation path instead of promising full autonomy. Each of those is a competitive stance against vendors selling single-model, token-metered, fully-autonomous agents. It is a coherent argument, and the fact that it appears here instead of a changelog means the product behind it is not observable from this source.
Expect the pricing and multi-model themes to keep recurring, since both are positioned as competitor weaknesses rather than one-off observations. Whether the product delivers on them cannot be judged without a real release feed.

Two moves stand out from the steady feature drip. Copilot went into every workspace as an agent builder that drafts an AI Agent from a description and runs test cases against it before publishing — respond.io is attacking the authoring problem, not the runtime one. Alongside it, AI Credit On-Demand converts the AI allowance from a hard cap into metered overage, so automation stops breaking mid-conversation and AI becomes consumption revenue. The remaining work is a methodical widening of channels and the surfaces an agent touches all day.
Expect more channels to arrive in the same shape Outlook did — inbox, workflows, and reports together — and Copilot's authoring surface to extend past agents into workflows. The AI Agent wait-time and Copilot test-case work both point toward more pre-publish validation tooling.
