A local Reddit keyword watcher with AI scoring and suggested replies is a weekend build. ReplyGain is more than that: it schedules ingestion across four platforms, normalizes and deduplicates posts, ranks purchase intent, sends alerts, generates replies, and keeps platform integrations working as APIs and feeds change. The core workflow is vibecodable, but a reliable multi-platform service has real maintenance and infrastructure gaps.
Der Moat
Ein Moat ist der Burggraben um ein Produkt: alles, was ein Nachbau nicht einfach mitkopieren kann, etwa Nutzer, Daten, Verträge oder Vertrauen. Je tiefer der Graben, desto eher lohnt sich das Abo trotz KI-Agent.Viele Schnittstellen brauchen OAuth, Pflege und zuverlässige Synchronisierung.
Globaler Betrieb und hohe Verfügbarkeit sind schwer selbst zu tragen.
Zuverlässigkeit und sauberer Feinschliff sparen dauerhaft Arbeit.
Der Prompt
Build a local, honest personal substitute for ReplyGain in an empty folder. Stack: Node 22, TypeScript, Express, better-sqlite3, and vanilla HTML/CSS/JS. Do not use React or a hosted database. Scope: Reddit and Hacker News only. - Import recent public posts using Reddit JSON endpoints and the Hacker News Algolia API - Let me enter a product description and keywords - Store posts in SQLite with source, URL, title, text, author, score, and discoveredAt - Use an OpenAI-compatible API from .env to classify purchase intent from 0 to 100 - Show a sortable local feed with intent score, source, matched keyword, and a link to the original post - Generate an editable suggested reply for one selected lead - Add seen, dismissed, and replied states; never post automatically - Poll on demand only; no background worker, billing, login, Telegram, email, X, Bluesky, or multi-user features - Include .env.example, README, seed data, and a smoke test that uses fixtures instead of live APIs - Explain in README that APIs, rate limits, moderation rules, and platform changes make this a personal prototype - Finish by listing the exact commands used to install, test, and run the app

The first script is easy. The useful version keeps scanning public conversations, removes duplicate and irrelevant posts, handles several platforms, remembers what has already been reviewed, and delivers the right lead at the right time. Founders pay to spend ten minutes reviewing opportunities instead of starting every day with two hours of manual searching.
Für den Eigenbedarf reicht der Eigenbau oben meistens.
