Amelia keeps widening from appointments into events, ticketing and payments.
Amelia is a WordPress booking plugin that announces each release as a blog post, roughly monthly. Across 8.5 through 9.7 the shape is consistent: appointments remain the core, but events take an increasing share — QR-code ticketing, invoicing, waiting lists, front-end display controls, and now public event pages in 9.7. Calendar integration and payment flexibility are the other steady threads, and 9.1 introduced Angie AI as an admin-side assistant alongside Outlook sync and Divi 5 support.
Respond.io upgraded its AI Agents to GPT-5.6 and added TikTok Business Messaging for US accounts.
Respond.io is shipping across three tracks simultaneously: AI Agent improvements (GPT-5.6 model upgrade, pre-publish instruction review), channel expansion (TikTok Business Messaging for US, Microsoft 365/Outlook email), and workflow automation (missed call auto-follow-up, Google Calendar integration). The status persistence fix — keeping agents online as long as the tab is open — addresses a real reliability concern for teams that rely on online/offline presence for routing.

The product is growing into a light events-and-payments layer inside WordPress rather than a scheduling widget. The IvyForms integration is the tell on strategy: instead of building a form builder, Amelia delegates pre-booking data collection to a sibling product, which points at a suite rather than one plugin. Full data export and import arriving in 9.7 is the housekeeping a product needs once customers have years of bookings inside it — and once moving between installations becomes a support question.
Public event pages give Amelia a front end it did not previously own, so making those pages promotable or discoverable is the natural next step. These posts are summaries rather than changelogs, so specifics are hard to read ahead of time.
Respond.io is shipping across three tracks simultaneously: AI Agent improvements (GPT-5.6 model upgrade, pre-publish instruction review), channel expansion (TikTok Business Messaging for US, Microsoft 365/Outlook email), and workflow automation (missed call auto-follow-up, Google Calendar integration). The status persistence fix — keeping agents online as long as the tab is open — addresses a real reliability concern for teams that rely on online/offline presence for routing.
The product is converging on a model where AI Agents handle routine conversations while human agents handle escalations, with channels increasingly auto-enrolled (missed calls become conversations, calendar events surface in the inbox). The channel expansion pace (TikTok, Microsoft 365, Google Calendar within weeks) suggests a deliberate push to cover every channel a business customer might use.
Voice channel integration — handling inbound calls with AI Agents rather than just converting missed calls into follow-ups — would complete the omnichannel picture respond.io is assembling.
