What is Respond.io?

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.

What is Sleekplan?

Sleekplan rebuilt itself around an AI layer that triages feedback instead of filing it.

Sleekplan spent 2026 on a rebuild rather than incremental releases. Sleekplan 2.0 entered beta in June with a rewritten admin app and an AI layer over the feedback loop; the Impact Score was rebuilt the same day to be inspectable and configurable rather than an opaque number. The Chrome extension has now been rebuilt to match, letting a team member search the board, add votes and post on a customer's behalf from wherever the feedback lands.

respond.io is layering an agent-authoring copilot and consumption billing on top of its omnichannel inbox.

◆ Current state

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.

◆ Where it's heading

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.

◆ Prediction

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.

2.5

Sleekplan rebuilt itself around an AI layer that triages feedback instead of filing it.

◆ Current state

Sleekplan spent 2026 on a rebuild rather than incremental releases. Sleekplan 2.0 entered beta in June with a rewritten admin app and an AI layer over the feedback loop; the Impact Score was rebuilt the same day to be inspectable and configurable rather than an opaque number. The Chrome extension has now been rebuilt to match, letting a team member search the board, add votes and post on a customer's behalf from wherever the feedback lands.

◆ Where it's heading

The pattern is capture-everywhere plus decide-automatically. Pulling feedback in from support inboxes, CRMs and call notes is one half; making prioritization explainable enough to run unattended is the other. Cadence is low and lumpy — a Linear integration in February, then nothing until the 2.0 beta — so the rebuild is consuming the roadmap.

◆ Prediction

The next release most likely moves 2.0 out of beta. The configurable Impact Score formula is the piece to watch, since it has to be trusted before the AI layer can prioritize without review.
