About the project
Briefer is a media monitoring platform I designed and built end to end for PR agencies and communications teams. Agencies usually track client mentions with Google Alerts, manual searches, and spreadsheets. Briefer automates that entire cycle: it continuously scans news, social platforms, video, and forums across 13 sources, deduplicates and translates what it finds, scores sentiment with an LLM, and flags potential crises before they grow.
The platform is fully multi-tenant — each agency's workspace is isolated at the database level with Postgres Row-Level Security — and subscription tiers enforce usage limits at runtime, from scan frequency to monthly mention caps. Reporting is built for agency workflows: branded PDF, PowerPoint, and Excel exports with an AI-written executive narrative, plus reputation scoring and share-of-voice analytics against competitors.
Under the hood, around 30 n8n workflows orchestrate the scanning pipeline, with a Next.js app on Supabase handling everything user-facing. Rate limiting runs on Upstash Redis, email goes through Resend, and a Vitest suite covers the API surface. Briefer is live at briefer.media in invite-only early access.
