You're in. Here's everything.
Two live kits, no funnels, no upsell. Kit 01 emails you a curated AI digest every morning at $0/month. Kit 02 turns your weekly notes into a newsletter draft in your voice. Both yours, free forever.
Daily AI Digest Kit — your own curated AI newsletter
A cron that emails you a curated AI digest every morning. $0/month, deploys in five minutes, runs on Vercel's free tier. No n8n, no Zapier, no paid scrapers. Most "build an AI digest" tutorials route you through a $20/mo workflow tool. This is one Next.js file and a deploy button.
HN via Algolia, GitHub via the search API, RSS via rss-parser. No Apify, no Twitter API, no rented residential proxies. Anthropic, OpenAI, DeepMind, Mistral, Hugging Face, Latent Space, Simon Willison, Sebastian Raschka, Import AI, The Batch — already wired in. Add or remove feeds in one config file.
A regex/weight table you edit by hand: MCP gets +80, agents get +60, your specific framework gets whatever you decide. Then a Claude Haiku call reads your interest profile in plain English and writes the digest in a voice that sounds like a friend tipping you off — not an LLM summary blob.
Headline pulled from the day's biggest story, source labels, hover-friendly link styles, dynamic date header, dark-mode safe. Sends through your own Gmail via an App Password — no domain verification, no Postmark account, no "from" address that screams "marketing tool."
The annoying thing about morning crons isn't the build — it's discovering three weeks later that the digest stopped arriving and you didn't notice. This one wraps the whole route in a try/catch that emails you the error so you can fix it the same morning.
The README walks you through every key — Anthropic API key, Gmail App Password, the cron secret. Total cost forever: pennies a month on Haiku. Total setup time: under five minutes if you already have a Vercel account.
Newsletter Writer Kit — your notes, your voice, shipped weekly
A Monday cron that reads your notes from the past week and emails you a newsletter draft. Most "AI newsletter" tools generate from scratch and the result sounds like an LLM. This one doesn't write — it assembles. It quotes your actual sentences, picks the strongest theme of the week, and gets you to "edit" instead of "blank page."
"You do NOT write FOR them. You ASSEMBLE what they already wrote. Quote from the notes liberally. Bridge with one sentence at most." That's the difference between a newsletter that sounds like you and a newsletter that sounds like ChatGPT did your homework. The model is reduced from author to editor — exactly the role it's actually good at.
Tone bullets, 2-3 paragraphs of your actual writing as live examples, hard-no rules ("no em dashes, no supercharge, no stay curious"), and an optional newsletter structure. Claude reads this every run. Most voice-matching tools rely on a one-line "write like X" prompt — this one gives the model real surface to mimic.
Uses the GitHub commits API to find files actually modified in the last 7 days — accurate mtimes, not folder scans. Read-only token, fine-grained scope. Works with any folder structure. The README has a one-time setup walkthrough for Obsidian users (install the Git plugin, point it at a private repo, done).
The model is told: "Where the user clearly has a thought but didn't finish it, leave a <!-- expand: ... --> comment instead of inventing content." So you open the draft and see exactly which lines need your finger and which are already shippable. No guessing what's yours and what's hallucinated.
Mondays at 8am ET, the cron sends you an email with the headline, the chosen theme, and the full draft attached as a markdown file. Open it in your editor, edit, paste into Beehiiv/Substack/wherever. Total cost on Sonnet 4.5: about a quarter a month at weekly cadence.
