In simple English
This tool acts as a sales assistant that finds potential customers, writes emails, and replies to messages on your computer. It runs in a continuous loop every fifteen minutes without you needing to press buttons. You do not pay separate fees for artificial intelligence usage because it uses your existing subscription. Every outgoing message waits for your manual approval before it is sent. You need a dedicated secondary email domain and some time to set it up correctly.
What it is
A Python-based autonomous sales agent that operates locally on your machine using your subscription-backed command-line interface. It combines prospect discovery, website profiling, email generation, and a local web dashboard into a single sqlite-backed package.
What it is good for
Solo founders and small business owners who want to run cold email campaigns for local services without paying hundreds of dollars every month for commercial sales platforms and separate AI token bills.
- Runs on your existing Claude Pro, Max, or ChatGPT subscription without per-token API costs.
- Keeps every outgoing email in an approval queue so nothing sends automatically by default.
- Stores all data locally in a sqlite database on your machine.
- Requires technical setup in the terminal with Python 3.11 or newer.
- Demands careful email domain configuration such as SPF, DKIM, and DMARC to avoid spam folders.
- Runs on macOS and Linux, with Windows not supported for the ChatGPT provider option.
