Introduction

Developer documentation for Selyf: how its Gmail integration, authentication, and AI features actually work.

What Selyf is

A security-first AI email assistant for Gmail, built read-only first: no sending, no deleting, no changes to your mailbox.

What this site is

This is technical documentation: the real authentication model, Gmail data flow, AI behavior, and system architecture behind Selyf — written for developers, security reviewers, and anyone evaluating the product who wants more than the marketing pitch at selyf.com.

Selyf's API is not currently offered as a public self-service platform — there is no sign-up flow for API keys, and it is not meant to be built on by third-party applications. This reference documents the API's real, live behavior for transparency, not as an invitation to integrate against it.
