BriefRadar
AI SEO brief generator + AI search tracker.
-
Public link (/): anyone can generate briefs, limited to PUBLIC_DAILY_LIMIT (default 5) per visitor per day.
-
Full article (/, second tab): finds the top 20 Google results (SerpApi, 2 searches), reads each page (respecting robots.txt), and has Nemotron 3 Ultra (free, via OpenRouter) write an original article from them with numbered citations. Every sentence is checked against the sources; any that are too close are rewritten automatically by Groq. Limited to ARTICLE_DAILY_LIMIT (default 2) per visitor per day.
-
Admin link (/admin): sign in with APP_PASSWORD for unlimited briefs, the AI visibility dashboard and settings with share links.
-
Built with Next.js, Tailwind CSS, shadcn-style components, Lucide icons and the Geist font.
-
Brief generator: keyword in, content brief out — search intent, heading outline, questions to answer, related keywords. Built from real Google data (autocomplete, People Also Ask, related searches) via SerpApi's free plan, written up by an LLM.
-
AI search tracker (/tracker): sends your prompts to ChatGPT, Perplexity, Gemini and Claude through their APIs and checks whether your brand (and competitors) are named. Runs on demand, and weekly via Vercel Cron.
-
Google Sheets (optional): every brief and tracker run is appended to your sheet.
Stack: Next.js (App Router) on Vercel. The API routes are the backend, so there's no separate server.
Honest limits
- Search volume and keyword difficulty aren't included — no free source provides them. Add Semrush or DataForSEO later if you need them.
- API answers are a close proxy for what people see in the ChatGPT/Perplexity/Gemini apps, not an exact copy (no personalisation, different search behaviour). Treat the tracker as a week-over-week trend.
- "Position" is your brand's order among the tracked names that appear in an answer.
Setup
- Deploy to Vercel (import this repo).
- In Project → Settings → Environment Variables, add the variables from
.env.example. Minimum for briefs: SERPAPI_KEY + GROQ_API_KEY (free at console.groq.com). Redeploy after adding them.
Briefs are written by Groq (openai/gpt-oss-120b by default) when GROQ_API_KEY is set. Groq's free tier allows about 1,000 requests and 200,000 tokens a day; one brief uses one request. Groq isn't an AI search product people use, so it isn't one of the tracker's engines.
3. Set APP_PASSWORD so strangers can't spend your quota, then enter it once in the site's Connections panel.
Weekly tracker
Set CRON_SECRET, TRACK_BRAND, TRACK_COMPETITORS and TRACK_PROMPTS (prompts separated by |). Vercel calls /api/cron/track every Monday at 03:00 UTC (08:30 IST). Each run handles up to 10 prompts.
Google Sheets
- Create a Google Cloud service account and a JSON key; enable the Google Sheets API.
- Create a sheet with two tabs:
Briefs and Tracker. Share it with the service account email as Editor.
- Set
GOOGLE_SHEET_ID (from the sheet URL), GOOGLE_SERVICE_ACCOUNT_EMAIL and GOOGLE_PRIVATE_KEY.
Column order — Briefs: created at, keyword, country, content type, intent, H1, outline, questions, related keywords, word count.
Tracker: run at, week, brand, prompt, engine, mentioned, position, competitors named, cited URLs, error.
