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.
3 LLM Providers
Choose Anthropic Claude, OpenAI, or Google Gemini. Switch anytime with one env var.
3 Subscriber Stores
Supabase, JSON file, or Google Sheets. Use what fits your workflow.
MCP Server
Review and send drafts conversationally in Claude Desktop. Manage subscribers too.
Two-stage pipeline
Automated drafting with human approval. Nothing sends without your sign-off.
Weekly Draft
Cryyer gathers merged PRs, releases, and notable commits from your GitHub repo. An LLM drafts a personalized email in your product's voice and creates a GitHub issue for review.
Send on Close
Review and edit the draft in GitHub. When you close the issue, Cryyer sends the email to all subscribers via Resend and posts delivery stats as a comment.
