About Angel Copilot – open-source tool for assessing startup deals
Angel Copilot is an open-source tool designed to help angel investors systematically evaluate startup opportunities.

Available as a custom GPT for quick use, an imported skill for single-deal workflows, or a local CLI for batch triage, it supports multiple output formats including markdown, HTML, CSV, JSON, and PDF.
