HelpCenter.io is building a funnel off Zendesk's weak spots — a free FAQ tool at one end, migration guides at the other.
The newest post is a migration playbook aimed squarely at Zendesk customers, arguing that Zendesk has no native article export and that its URLs stop working when the subscription does. That editorial sits on top of a genuine product run: FAQs.me, a standalone free FAQ builder with no account, watermark, or callback scripts; Template Editor v2 for per-page design control; a rebuilt support widget whose AI answers cite their sources; and analytics rebuilt to report a self-service resolution rate.
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 pieces fit into one motion. FAQs.me and the migration content both bring people in without a sales conversation, the widget and template work make the product worth keeping, and the analytics rebuild supplies the number that justifies it. The company is targeting switchers rather than new buyers, and the argument it makes is about lock-in — export and URL ownership — rather than features. Content and product are being pointed at the same competitor.
Expect more migration material covering other incumbents, and for the resolution-rate metric to become the number the product is sold on. Whether FAQs.me converts into paid accounts is the open question, and nothing visible here reports on it yet.

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.
