Stack Reach scans Substack Notes and surfaces the handful actually worth your reply — matched to your beat, ranked by reach, with a drafted angle for each. Free, open source, and runs on your own machine.
"Alibaba is likely to end this quarter as the single largest provider of tokens processed globally. ByteDance is second…"
"Why the uneven safety policies matter more than the benchmark scores everyone's quoting…"
"The thing nobody wants to say about AI assistants replacing search is who you hold accountable…"
"You're not supposed to prompt the model — you're supposed to build a system that prompts itself…"
"Nobody's talking about which jobs, in which countries, the AI shock actually lands on first…"
Stack Reach reads your bio and recent posts to build a profile of the topics you actually write about — no manual tagging.
Every refresh, it scores incoming notes — from people you follow and writers you haven't found yet — for relevance to your beat, ranked by reach and engagement.
Each opportunity comes with a drafted reply angle in your voice. Respond, skip, or archive — and keep a log of what you acted on.
Slide between peer writers (mutual growth) and high-visibility accounts (audience reach). Both surface from the same scored feed.
EU AI policy today, infrastructure pricing tomorrow. On-topic notes float to the top instantly — layered over the meter.
Each opportunity comes with a specific angle that references your own work where it fits — a starting point to rewrite or ignore, not something to paste.
Mark what you acted on. Dismissed notes move to an archive you can revisit — so you never double-reply or forget a thread.
Stack Reach surfaces opportunities and drafts angles — you decide what to say and when. Nothing is ever auto-posted on your behalf. Your voice stays yours.
No account, no signup, nothing collected. Stack Reach runs on your own machine with your own Substack session and the LLM of your choice — local (LM Studio, Ollama) or your own API key (OpenAI, Claude, OpenRouter). Clone it and go.
