Why ChatGPT works better with PostLake

Agent-native, not bolted on. 18 MCP tools, idempotency keys and agent-safe retries so ChatGPT never double-posts.

One normalised shape. Every platform returns the same response, so ChatGPT can reason over it without special-casing.

Deep analytics. Cross-platform reach, engagement and growth in one response, so your agent can decide what to post next.
