Plain vs Knowmax: at a glance
What is Plain?
Plain is turning Sidekick from an assist tool into an agent that acts across your stack.
Plain is a customer-support platform whose changelog is now largely the story of Sidekick, its AI agent. This window gives Sidekick a dedicated home page, puts it inside workflows so it starts working the moment a thread matches, and lets it take actions across connected tools and inside Plain. Around it are supporting workflow and integration updates: scheduled workflows, chat-widget thread fields, and Linear issue linking.
What is Knowmax?
Knowmax's feed is CX thought-leadership content, not a product changelog
Everything on this feed is blog content: trend roundups, buyer's guides, and how-tos on knowledge management and customer service. There are no shipped product changes here, so it reflects Knowmax's content marketing rather than its release cadence. The editorial center of gravity is the collision of AI agents and customer-service knowledge bases, the space Knowmax sells into.

Plain is turning Sidekick from an assist tool into an agent that acts across your stack.
◆ Current state
Plain is a customer-support platform whose changelog is now largely the story of Sidekick, its AI agent. This window gives Sidekick a dedicated home page, puts it inside workflows so it starts working the moment a thread matches, and lets it take actions across connected tools and inside Plain. Around it are supporting workflow and integration updates: scheduled workflows, chat-widget thread fields, and Linear issue linking.
◆ Where it's heading
Sidekick is moving from suggesting to doing: proactive triage via workflows, action-taking across connected tools, and presence in Slack all point at Plain building an autonomous support teammate rather than a reply-drafting assistant. The workflow and API plumbing shipping alongside (scheduling, thread-field passthrough) is the connective tissue that lets Sidekick act on richer context automatically.
◆ Prediction
Expect deeper Sidekick autonomy next, with more action types across integrations and tighter workflow triggers, while Plain keeps hardening the surrounding automation and API surface that feeds it.

Knowmax's feed is CX thought-leadership content, not a product changelog
◆ Current state
Everything on this feed is blog content: trend roundups, buyer's guides, and how-tos on knowledge management and customer service. There are no shipped product changes here, so it reflects Knowmax's content marketing rather than its release cadence. The editorial center of gravity is the collision of AI agents and customer-service knowledge bases, the space Knowmax sells into.
◆ Where it's heading
The recent posts lean hard into one thesis: consumer-side AI agents are about to hit contact centers, and knowledge search is the bottleneck. That framing positions Knowmax's knowledge-base product as the missing infrastructure for an agent-driven CX world. Alongside the thought-leadership sit the usual SEO comparison pieces (eGain alternatives, platform roundups) aimed at capturing buyers mid-search. None of it is a product signal.
◆ Prediction
Expect continued content on AI agents in customer service and knowledge management, on the same cadence. What actually ships in the product isn't visible from this blog feed, so any roadmap read would be speculation.
