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 Pylon?
Pylon is wrapping intelligence layers around customer support and feedback.
Pylon ships weekly bundles across four pillars: Support System, Product Intelligence, Account Intelligence, and AI Agents. November introduced Product Intelligence (auto-extraction of feature requests from interactions) and Google Meet ingestion. January and February layered Salesforce/HubSpot contact sync, Linear bidirectional comments, account-notebook time filters, and dashboard drill-downs. March added event-driven task creation, customer-notification tracking on closed feature requests, reusable knowledge-base blocks, and native video. April brought bulk project actions, contact phone numbers in issues, and task/project triggers.
Plain vs Pylon: 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.
Pylon
0.0SUPPORT
Pylon is wrapping intelligence layers around customer support and feedback.
◆ Current state
Pylon ships weekly bundles across four pillars: Support System, Product Intelligence, Account Intelligence, and AI Agents. November introduced Product Intelligence (auto-extraction of feature requests from interactions) and Google Meet ingestion. January and February layered Salesforce/HubSpot contact sync, Linear bidirectional comments, account-notebook time filters, and dashboard drill-downs. March added event-driven task creation, customer-notification tracking on closed feature requests, reusable knowledge-base blocks, and native video. April brought bulk project actions, contact phone numbers in issues, and task/project triggers.
◆ Where it's heading
Pylon is positioning as a customer-support-plus-intelligence platform that closes the loop from incoming signal to product action. Bidirectional ties to Linear, Jira, Salesforce, and HubSpot make it the connective tissue between support and the rest of the org. Expect AI Agents and trigger automation to absorb more of the manual routing work, and Account Intelligence to keep deepening its analytics surface.
◆ Prediction
The next directional move likely connects AI Agents and triggers into multi-step autonomous flows that route, escalate, and close issues. The intelligence layer is likely to add more data sources (Zoom, Gong, intercom logs) and surface predictive metrics like churn risk on accounts.
