Integrate with other agents

Plain integrates with a number of third-party AI agent providers that can automatically resolve customer support threads on your behalf. These agents connect to Plain as machine users, listen for incoming threads via webhooks, and respond using your existing knowledge sources and tools.

See Using your own agent for a complete guide to the integration architecture.

Below is a summary of our partners:

Decimal

Decimal traces customer questions directly to relevant source code, configuration files, and release notes to generate accurate answers. Its self-healing knowledge base automatically updates as your product changes.

Duckie

Duckie brings agents that connect to 20+ tools your team already uses, including Slack, Notion, Jira, and your codebase. It can act as either an autonomous agent or a copilot.

Parahelp

Parahelp allows you to define custom procedures so that agents can take actions on behalf of customers, such as looking up subscription details, processing refunds, or filing bugs by connecting to tools like Stripe, Slack, and Linear alongside your documentation.

Inkeep

Inkeep provides Keep, a support copilot. Keep's Smart Assist mode analyzes the thread you're viewing and generates context-aware suggestions, including draft answers, relevant doc links, thread summaries, and follow-up to-dos.

Keep is fully conversational, so you can ask it to refine or expand its responses.

Building your own agent

If you'd prefer to build a custom integration, Plain's API supports bringing your own agent. You can set up machine users, subscribe to webhooks, manage agent status, and handle the full reply-and-handoff flow yourself.
