# Build brief — a focused alternative to Ideabrowser > **Verdict:** Partly, if you narrow it · **Buildability:** 50/100 · **Category:** User Research > **Source:** https://www.canitbevibecoded.com/ideabrowser > Independent editorial assessment from Can It Be Vibe Coded? Not affiliated with, endorsed by, or derived from Ideabrowser. Verify current pricing and capabilities before acting. ## Context **Ideabrowser** — Daily curated startup ideas backed by trend data, market sizing and AI research agents. It currently costs $41.58/mo. Scraping Reddit/search trends and having an LLM draft a business-opportunity writeup per idea is a focused 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. This brief describes a focused, single-operator replacement for the part of Ideabrowser that is genuinely reproducible. It is deliberately narrower than the product it replaces, and it says so in writing. Build the useful core; do not pretend to have rebuilt the rest. ## What you are building A script that pulls trending Reddit/Google-Trends signals, feeds them to an LLM with a fixed prompt template, and outputs a formatted market-opportunity brief. - Store interview notes, tag observations, and synthesize themes across sessions. - A responsive interface with real empty, loading, success, and error states. ## Requirements ### Data and integrations - OpenAI/Anthropic API key. - Reddit or Google Trends API access. Each of these needs a real account, credential, or quota. Set them up before writing feature code. ### Non-functional - Accessibility: semantic markup, labelled controls, visible focus, and reduced-motion support. - Security: server-side secrets, validated input, and no credentials in the client bundle. - Reliability: retries with backoff on external calls, and a clear failure state when a provider is down. - Portability: the operator can export their data and leave without losing it. ## Implementation brief 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. ## Delivery standard - Inspect the repository first, then write a short implementation plan before writing code. - Deliver the smallest complete end-to-end workflow first; every primary control must work against persisted data. - Use real validation and storage; never substitute fake dashboards, decorative controls, hard-coded success states, or mock integrations. - Include responsive layouts plus genuine empty, loading, success, validation, and failure states. - Keep secrets server-side in environment variables, provide .env.example, and never commit credentials or user data. - Add structured logs around every external call and return actionable errors without leaking sensitive details. - Write unit tests for the core logic and one automated test of the main user journey. - Finish with a README covering setup, architecture, data location, backups, tests, deployment, and known limitations. ## Acceptance criteria - [ ] A clean install starts the app using only the README and .env.example. - [ ] The primary journey works from first visit through saved result, reload, edit, export, and deletion where applicable. - [ ] Invalid input, missing configuration, provider failure, and an empty database each have a usable state. - [ ] The interface works at 390px and 1440px, is keyboard navigable, and shows visible focus on every control. - [ ] Tests, type checking, linting, and a production build all pass with no ignored failures. - [ ] No part of the interface implies a live integration, security guarantee, or scale capability that was not actually built and verified. ## Non-goals Do not build these, and do not claim to have replaced them: - 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. ## What you still own after launch - Secure credentials, rotate secrets, and handle provider rate limits. - Run migrations, backups, restores, and dependency updates. - Test the critical journey after every model, API, or hosting change. - Monitor failures and fix the edge cases a first prompt will miss. ## Risk **Operational risk.** The code is achievable; dependable data, integrations, and ongoing operations are the real cost. Editorial confidence in this assessment: medium. No reviewed project implementation is linked yet. ## Existing alternatives Before building, compare these checked options: - [IdeaProof](https://ideaproof.io/startup-ideas-database) — Free searchable database of startup ideas with market size and viability scores, no subscription ## Prior art Working open-source software you can read, fork, or borrow from before starting: - [praw](https://github.com/praw-dev/praw) — Python Reddit API wrapper for pulling trending threads --- Generated by [Can It Be Vibe Coded?](https://www.canitbevibecoded.com) · Full report: https://www.canitbevibecoded.com/ideabrowser
