✓ Pillar | App Copilot
A control plane that turns your APIs and docs into one AI agent deployed across Slack, Discord, MCP, and your app.
Why we recommend them
Pillar is an open-source SDK/platform for building AI copilots without stitching together separate frontend, agent framework, and vector database tools. Teams connect their APIs (via OpenAPI, MCP, or code) and knowledge sources once, then deploy the same reasoning engine to Slack, Discord, in-app widgets, and MCP clients from a single dashboard. Built for engineering teams who want to ship agents fast and update tools/knowledge in one place instead of redeploying per channel.
✓Usage-based pricing: only substantive AI responses are billed, not greetings
✓Free tier includes 50 one-time responses with no card required
✓One agent config powers Slack, Discord, in-app copilot, and MCP simultaneously
