What is Plain?

Plain built an autonomous support agent, and has now built the controls to trust it.

Plain's changelog is dated entries with no titles, and nearly all of it concerns two AI surfaces: Ari, the customer-facing responder, and Sidekick, the internal agent. Sidekick spent July gaining reach — its own full-page home, reusable workspace skills, and connection to arbitrary MCP servers. The newest release turns to Ari and adds what was missing around it: a way to test it before customers see it, provenance behind each answer, configurable tone, and explicit escalation rules.

What is Sleekplan?

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.

Plain vs Sleekplan: editorial side-by-side

P

SUPPORT
8.8

Plain built an autonomous support agent, and has now built the controls to trust it.

◆ Current state

Plain's changelog is dated entries with no titles, and nearly all of it concerns two AI surfaces: Ari, the customer-facing responder, and Sidekick, the internal agent. Sidekick spent July gaining reach — its own full-page home, reusable workspace skills, and connection to arbitrary MCP servers. The newest release turns to Ari and adds what was missing around it: a way to test it before customers see it, provenance behind each answer, configurable tone, and explicit escalation rules.

◆ Where it's heading

The sequence reads as capability first, then governance. Plain rebuilt Ari into an agentic first responder, opened Sidekick to any MCP server, and let teams write skills the whole workspace shares — all of which widen what the agents can do and reach. The current release closes the loop the other way, making that autonomy inspectable and bounded before it is switched on. That is the order support-AI vendors have to complete in: teams will not put an agent in front of customers on capability claims alone.

◆ Prediction

With testing and provenance in place, the next step is likely measurement — resolution and escalation rates per skill, or per-answer quality review feeding back into the skills teams write. The entries are short summaries linking off-site, so per-release depth is limited.

Sleekplan rebuilt itself around AI triage, then put the feedback board inside ChatGPT.

◆ Current state

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.

◆ Where it's heading

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.

◆ Prediction

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.
