Cryyer

Automated product updates
powered by AI

Cryyer gathers your GitHub activity, drafts personalized emails with AI, and sends them — with a human review step in between.

Everything you need

From gathering activity to sending emails — fully automated, fully customizable.

AI-Drafted Emails

LLM-powered drafts with per-product voice. Your updates sound like you, not a robot.

GitHub Activity

Automatically gathers merged PRs, releases, and notable commits. No manual changelog writing.

Human-in-the-Loop

Drafts become GitHub issues for review. Edit, approve, or regenerate before sending.

Automated drafting with human approval. Nothing sends without your sign-off.

Monday (automated)
