Create your first newsletter

Follow these steps to go from zero to receiving curated content in your inbox.
1

Sign up

Head to reduce.sh and create an account. You can sign up with email/password or Google sign-in.
2

Create a newsletter

Click New Newsletter and give it a name and optional description. For example: “AI Coding Weekly”.
3

Add sources

Paste URLs for content sources to follow. You can add:
  • YouTube channels — e.g., @fireship, @anthropic-ai
  • Subreddits — e.g., r/ClaudeAI, r/LocalLLaMA
  • X/Twitter accounts — e.g., @AnthropicAI
Start with 3-5 sources. You can always add more later.
4

Create sections

Sections define what content to extract from your sources. Each section has a name and a prompt.For example:
  • New Tools → “New AI coding tools and extensions that have been released”
  • Tips & Techniques → “Practical tips for using AI assistants in coding workflows”
Keywords from your prompt are used to match relevant content from your sources, then the AI summarizes the matched content.
5

Set your cadence

Choose how often you want to receive your newsletter:
  • Daily — every morning
  • Weekly — pick a day (e.g., every Monday)
  • Custom — specific days of the week, every X days, etc.
6

Activate

Toggle your newsletter to active. You’ll start receiving emails at your next scheduled delivery time.

​
What happens next

At each scheduled delivery:
  1. Reduce fetches all new content from your sources (since your last delivery)
  2. Keywords from each section’s prompt are matched against content titles and descriptions
  3. Matched content is passed to the AI, which generates bullet-point summaries with key highlights
  4. A formatted email is sent to your inbox
Every delivery only includes fresh content — no duplicates across deliveries.
