Plain
Plain built an autonomous support agent, and has now built the controls to trust it.
A side-by-side editorial comparison of Knowmax and Zendesk — release velocity, themes, recent moves, and the top alternatives to consider.
A teaser-only content feed making one argument: AI in the contact center fails on knowledge, not models.
Knowmax's feed carries no product releases. It is a marketing blog whose entries arrive as titles with a one-line stub, publishing two or three times a week on a single theme - that contact center AI underperforms because the underlying knowledge base is not ready, not because the models are weak. Around that sit cost-of-knowledge-gap figures, EU AI Act compliance deadlines, and head-to-head comparison pages against Guru and Confluence.
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.

The editorial line is consistent and clearly aimed at a buying committee evaluating AI agents for customer service: reframe the purchase from a model decision to a knowledge-foundation decision, which is the thing Knowmax sells. The comparison pages published back-to-back in early August suggest active competitive pressure in deals. None of this reveals anything about the product itself, since the feed does not carry releases.
Expect the same cadence of framework posts, cost arguments, and comparison pages; product changes would need a separate changelog to be visible here.

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.
