Can I vibecode Ideabrowser?
KINDA · weekend projectScraping Reddit/search trends and having an LLM draft a business-opportunity writeup per idea is a weekend build. What's genuinely hard to replicate is the editorial curation, the accumulated database of 1,000+ pre-researched ideas, and the trend-signal pipeline built up over time. A DIY version can generate plausible-sounding ideas on demand but starts from zero data and zero curation.
Build me a startup-idea trend scanner as a Next.js app. Stack: Next.js + TypeScript, SQLite via better-sqlite3, Tailwind. No auth, single user, localhost only. Core loop: 1. A cron-style script (runnable manually via a button) that fetches the top posts from a fixed list of subreddits (via Reddit's public JSON endpoints, no API key needed) mentioning pain points or requests. 2. Pass each candidate post to the Anthropic API (key from .env) with a fixed prompt asking it to draft a one-page opportunity brief: problem, target user, rough market size guess, an MVP scope, and a one-line pricing idea. 3. Save each brief to SQLite and show them in a simple feed, newest first, with a save/star toggle. 4. A search box to filter saved briefs by keyword. Out of scope: payments, email delivery, multi-user accounts, historical trend charts, editorial curation. Include a README covering setup, the .env variable, and a note that brief quality depends entirely on the source posts fetched.

Builders pay to skip the research grind: a constantly refreshed, pre-vetted idea backlog plus market sizing is worth more to them than the marginal cost of prompting an LLM themselves, especially since the curation quality is hard to bootstrap solo.

Can I vibecode Ideabrowser?
Kinda. The core of Ideabrowser is buildable in a weekend with the prompt on this page, but there are real gaps: 1,000+ already-curated and human-vetted ideas, historical trend database and idea archive. Read the honest list above before committing.

Honestly: 1,000+ already-curated and human-vetted ideas; historical trend database and idea archive; AI Research Agent for arbitrary custom ideas; community, coaching and Q&A strategist sessions; data exports and idea-suggest personalization. If any of those are load-bearing for you, keep paying.
