Build a weekly AI digest agent that summarises the newsletters you follow
A step-by-step tutorial for an agent that collects several AI newsletters, summarises them with Claude against a personal preferences document, and delivers a weekly digest.

The business problem
Founders and product people cannot keep up with many AI newsletters but need the relevant tips and tools.
What was tried
The tutorial defines the job and success criteria (for example five bullets per newsletter), then offers two paths. No-code: label and forward newsletter emails, trigger a Zapier or Make flow, send the text to Claude with a prompt asking for top insights, one action and tools to investigate, and email the result. Light-code: pull RSS feeds in a Replit script and call the Claude API. A preferences document describing your projects and knowledge gaps is added to the prompt to make summaries relevant. Delivery is batched weekly, with links and dates, and a 1 to 5 rating feeds back into later runs. Extensions include a trending-topics section and a Notion tool library.
What was reported (not reported)
No outcome is reported. The post asserts that the preferences document improves relevance but gives no data.
Limitations
A general tutorial with no measured results, cost, code or error handling. The Replit script is described in one sentence. It does not address newsletter terms of use or sending third-party content to an API. Published April 2025, so tools may have changed.
What you need
A Zapier, Make or n8n account, or a Replit account, plus a Claude API key.
