Plain — AI support infrastructure for B2B teams

Plain is the AI-native Customer Support Platform for B2B SaaS and developer-forward companies. It is composable, API-first support infrastructure that unifies conversations across Slack, Microsoft Teams, Discord, email, contact forms, in-app chat, and API into one workspace — built so teams can assemble their own support motion, no-code or all-code.

Own this site? Verify it

Verified listings rank first, reach the featured tier (do-follow links) at 60 authority instead of 70, get a link in our llms.txt, a badge, breakage alerts, an editable profile, lookup analytics, and instant re-crawls. Prove ownership with any one of these, then call the verify endpoint (or your agent can do all of it, also over MCP).

  1. llms.txt link (recommended) — add this line to your llms.txt:
    - [Agent Web Map](https://agentwebmap.com/domain/plain.com?verify=awm_c2915ad5309378f4860a0c704415cdd5)
  2. DNS — add a TXT record:
    _agentwebmap.plain.com. TXT "awm-verify=awm_c2915ad5309378f4860a0c704415cdd5"
  3. Meta tag — in your homepage <head>:
    <meta name="agentwebmap-verify" content="awm_c2915ad5309378f4860a0c704415cdd5">
  4. Well-known file — serve the token at:
    https://plain.com/.well-known/agentwebmap-verify.txt  ->  awm_c2915ad5309378f4860a0c704415cdd5

Then: curl -X POST https://agentwebmap.com/v1/sites/plain.com/verify — the response contains your API key. Full docs.
