Gmail-based support tooling wiring internal docs into its AI and unifying search across channels
Hiver's April releases center on grounding its AI in a company's own material. Confluence pages, Google Docs and Google Sheets can be added as knowledge sources, and Ask AI can query an uploaded Sheet directly — answering questions like top customers by revenue without manual analysis. Alongside that, Omnichannel Search spans email, chat and Slack with unified results and channel attribution, and automations gained a trigger for conversations moved into a shared inbox. Each release appears twice in the feed.
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 product is extending past the shared-inbox job into being the place a support agent finds any answer. Knowledge sources make the AI useful on internal SOPs rather than generic replies; omnichannel search makes prior context findable regardless of where the conversation happened. Both reduce the reasons an agent leaves Gmail, which is the whole premise Hiver sells on.
Expect more knowledge source connectors on the pattern set by Drive and Confluence, since the Sheets query capability shows the ingestion path already handles structured as well as prose content.

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.
