Plain vs Sleekplan: at a glance
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 is shipping enterprise-grade B2B features at speed: SCIM, account-level feedback groups, and internal product documentation in a single sprint.
Sleekplan has entered a period of rapid enterprise feature development following its 2.0 rebuild in June. The recent wave includes SCIM directory sync (Okta, Entra ID, OneLogin), account-level Groups that reweight feedback by company rather than individual user counts, identity privacy controls for public boards, internal-only status visibility, Components as a second taxonomy axis, and internal Documents for PRDs and decision records. This is not incremental polish — each addition addresses a distinct enterprise sales objection.
Plain vs Sleekplan: editorial side-by-side
Plain
8.8SUPPORT
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
8.8SUPPORT
Sleekplan is shipping enterprise-grade B2B features at speed: SCIM, account-level feedback groups, and internal product documentation in a single sprint.
◆ Current state
Sleekplan has entered a period of rapid enterprise feature development following its 2.0 rebuild in June. The recent wave includes SCIM directory sync (Okta, Entra ID, OneLogin), account-level Groups that reweight feedback by company rather than individual user counts, identity privacy controls for public boards, internal-only status visibility, Components as a second taxonomy axis, and internal Documents for PRDs and decision records. This is not incremental polish — each addition addresses a distinct enterprise sales objection.
◆ Where it's heading
Sleekplan is systematically closing the gap between a startup-friendly feedback tool and something IT and procurement teams can approve at mid-market and enterprise accounts. SCIM removes the manual provisioning burden, Groups make the feedback data credible for B2B prioritization decisions, and Documents keep the reasoning inside the tool rather than scattered across Notion or Confluence. The trajectory is clear: become the product feedback system of record for B2B SaaS teams.
◆ Prediction
SSO (SAML) and role-based access controls are the next likely additions to complete the enterprise security checklist, and Groups will likely gain weighting by contract value (ARR) once customers start requesting customer-revenue-aware prioritization.
