Plain vs Xurrent: 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 Xurrent?
Sera AI crosses from assistant to autonomous agent while the ITSM core keeps its monthly grind.
Xurrent ships on a disciplined monthly cadence, and the last quarter splits cleanly in two. One half is steady ITSM plumbing — shared tags across Requests, Problems, Workflows and Projects, CMDB reconciliation that a human can actually read, iPaaS connectors, self-service reservations. The other half is Sera AI, which moved from a chat widget to a configurable studio and then, on 10 July, to two agents that act without a person in the loop.
Plain vs Xurrent: 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.
Xurrent
6.3SUPPORT
Sera AI crosses from assistant to autonomous agent while the ITSM core keeps its monthly grind.
◆ Current state
Xurrent ships on a disciplined monthly cadence, and the last quarter splits cleanly in two. One half is steady ITSM plumbing — shared tags across Requests, Problems, Workflows and Projects, CMDB reconciliation that a human can actually read, iPaaS connectors, self-service reservations. The other half is Sera AI, which moved from a chat widget to a configurable studio and then, on 10 July, to two agents that act without a person in the loop.
◆ Where it's heading
The two tracks are converging rather than running in parallel. Knowledge article readiness, CI location hints and reconciliation legibility are not standalone features — they are the data-quality preconditions an agent needs before it can be trusted to close a request. Xurrent is building the substrate first and letting Sera consume it, which is why the agent work has landed without the usual rollback noise. Agent Designer success metrics suggest the next constraint is proving the agents work, not shipping more of them.
◆ Prediction
Expect the agent count to grow slowly and the governance surface around it to grow faster — more Golden Set tooling, more per-agent success reporting, and tighter scoping of which request types an agent may close unaided.
