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.
Vitally's only visible release is a feature name and nothing more.
Vitally has a single changelog entry on record: a release titled Collections with no description beyond a generic teaser. Nothing in the feed says what Collections does or who it is for.
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.
Vitally has a single changelog entry on record: a release titled Collections with no description beyond a generic teaser. Nothing in the feed says what Collections does or who it is for.
With one undated, contentless entry there is no observable arc yet. The name suggests a way to group accounts or resources, but the entry does not confirm it.
The feed gives too little to support a prediction; the next entry will show whether Collections is a grouping layer or something else.
