What is Frill?
Frill is turning its feedback board from a destination into something machines read on demand.
The MCP server is the centrepiece: ten tools, one API key, no configuration, callable from Claude, ChatGPT, Cursor or Intercom Fin, and included on every plan rather than gated. The Chrome extension follows the same instinct from the capture side — grab an idea wherever you spot it, and collapse a long help desk thread into a clean idea with an AI summary in one click. Behind both sits the June groundwork: a public npm SDK, multiple API keys, webhook handling, and MCP in public beta.
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.
Frill vs Respond.io: editorial side-by-side
Frill
6.3SUPPORT
Frill is turning its feedback board from a destination into something machines read on demand.
◆ Current state
The MCP server is the centrepiece: ten tools, one API key, no configuration, callable from Claude, ChatGPT, Cursor or Intercom Fin, and included on every plan rather than gated. The Chrome extension follows the same instinct from the capture side — grab an idea wherever you spot it, and collapse a long help desk thread into a clean idea with an AI summary in one click. Behind both sits the June groundwork: a public npm SDK, multiple API keys, webhook handling, and MCP in public beta.
◆ Where it's heading
Frill is systematically removing the requirement to be in Frill. Capture moves to wherever the conversation already happens; retrieval moves to whatever assistant the team already uses. That reframes the product as the feedback store rather than the feedback interface, and the pricing decision reinforces it — putting MCP on every plan optimises for the corpus being queried, not for upsell. The earlier enterprise work (EU hosting, EntraID SSO, CSP) is what makes that store trustworthy enough to hold the data.
◆ Prediction
Expect write paths to follow the read paths — an assistant that can already ask what users want will next be expected to file, merge and status ideas — and expect more capture surfaces beyond the browser extension.
Respond.io
7.5COMMSSUPPORT
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.
