TL;DR
Plain organizes support tickets. Clarm generates revenue. If you need a clean support platform for your engineering team, Plain is a great choice. But if you want support AND revenue intelligence in one tool—where every conversation is a potential deal—Clarm is the better fit.
The Core Difference
Plain is a beautifully designed support platform built for technical teams. It does one thing well: organizing and managing support conversations. The design is thoughtful, the integrations are solid, and the developer experience is excellent.
Clarm does everything Plain does and more. It's not just a support tool—it's an AI Revenue Desk that identifies which support conversations are actually revenue opportunities, scores buyer intent, and routes signals to your team in real time.
Feature-by-Feature Comparison
AI-First Responses
Plain has AI features, but they're support-focused—designed to assist agents, not replace them. Clarm's AI handles 94% of inbound autonomously. It learns from your docs, codebase, and past conversations to provide sourced, accurate answers without human intervention.
24/7 Autonomous Operation
Plain requires agents to respond. After hours, conversations wait. Clarm operates around the clock with full context—no matter when a developer asks a question, they get an accurate, sourced answer immediately.
Channel Coverage
Both platforms connect to Discord, GitHub, Slack, web chat, and email. This is one area where Plain and Clarm are closely matched. The difference is what happens after the conversation is captured.
Buyer Intent Detection
Plain treats every conversation as a support ticket. Clarm classifies conversations by intent—distinguishing between a routine support question, a pricing inquiry, an enterprise evaluation, and a compliance review. Revenue conversations get flagged and routed differently from support tickets.
Revenue Signal Routing
Plain routes tickets to support agents. Clarm routes revenue signals to your sales workflow. When someone in Discord asks about enterprise pricing, Clarm doesn't just answer the question—it flags the conversation, enriches the lead, and pings your team in Slack.
Content Engine & SEO
Plain focuses purely on support. You still need a separate content strategy. Clarm includes a built-in content engine that writes SEO-optimized technical articles from your support knowledge, driving organic developer traffic to your product.
Why Teams Switch to Clarm
Revenue, Not Just Support

AI That Actually Deflects

Content Engine Included

Built for Conversion

On-Prem & Compliance
Clarm supports on-premise deployment for teams with strict data residency requirements. Plain is cloud-only. Both are SOC 2 compliant, but Clarm also offers CRM integration and deeper support deflection analytics.
The Bottom Line
