Plain
Plain built an autonomous support agent, and has now built the controls to trust it.
A side-by-side editorial comparison of Sleekplan and Zendesk — release velocity, themes, recent moves, and the top alternatives to consider.
Sleekplan rebuilt itself around AI triage, then put the feedback board inside ChatGPT.
Releases are infrequent and arrive as monthly digests with truncated bodies, so scope has to be inferred from direction. The June 2.0 rebuild replaced the admin app and added an AI layer for handling feedback; July connects a workspace to ChatGPT, anonymizes identities on public boards, and adds @-mentions to composers. A rebuilt Chrome extension sits between them, aimed at capture from other tools.
Zendesk's feed is a run of monthly digest stubs — including the same month twice.
Every entry in this window is a 'What's new in Zendesk' monthly pointer covering support, messaging, AI and analytics, with no feature detail in the body. November 2025 appears twice, and the crawled dates cluster in May 2026 rather than tracking the months the digests describe.

Both ends of the loop are being pushed out of Sleekplan's own interface. Capture moves to the browser extension where support and sales already work; management moves into the assistant a product manager already has open. The Impact Score rework and identity anonymization address the two objections that follow — that prioritization is opaque, and that public boards leak customer identity.
Expect the ChatGPT connection to be joined by other assistant surfaces on the same pattern, and the 2.0 beta to reach general availability with the AI triage layer as its headline.

Nothing about product direction can be read from these entries — they are index pages, not release notes. The real feature stream sits behind the links, which means Zendesk's actual pace and priorities are not visible in this feed as it is being captured.
The digest cadence will continue monthly, so meaningful signal here depends on the crawler reaching the linked release content rather than the announcement stubs.
