The job search, weaponized for the qualified.
A citation-grounded AI job application copilot with Chrome extension, Gmail tracking, and three pricing tiers.
The challenge
Job seekers face a documentation problem, not an inspiration problem. They know what they want to say — they just need help saying it in language that matches the role, passes ATS screening, and sounds like a human wrote it. Tools that generate generic cover letters from nothing miss the entire point.
Jobpoise was built around citation-grounded generation: every piece of AI-generated content traces back to the candidate's actual experience, the actual job description, and named sources. No hallucinated accomplishments. No fabricated skills.
The challenge: building a product that is technically defensible (citation-grounded), commercially sustainable (Stripe paywall with sensible tier design), and usable in the actual workflow (Chrome extension for in-browser job applications and Gmail integration for application tracking) — all in a single Next.js monorepo.
How we built it
Monorepo: Next.js 15 with Turborepo — web app and Chrome extension as separate packages, sharing types and utility functions. AI layer: GPT-4 with structured prompting for citation-grounded generation. Every output includes a citation map linking content to input sources (resume bullets, JD requirements).
Chrome extension: Manifest V2, injects into major job board UIs (LinkedIn, Indeed, Greenhouse), enables one-click draft generation from the current JD. Gmail integration: OAuth-scoped Gmail API access to track sent applications, surface follow-up timing, and detect response patterns.
Billing: Stripe Checkout + Customer Portal. Three tiers — Drift (free) to prove value, Poise ($39/mo) for unlimited generations + Gmail tracking, Compose ($79/mo) for Chrome extension + priority processing. CI: 5 CI checks passing on main — type check, lint, unit tests, build, and E2E smoke test.
What shipped
Next.js 15 monorepo (web app + Chrome extension as packages). Citation-grounded AI generation (GPT-4 + structured prompt layer). Chrome extension v2 with job board injection. Gmail OAuth integration with application tracking dashboard.
Stripe Checkout + Customer Portal (3 tiers). 5 CI checks passing on main branch. Production deployment with auth, data persistence, and billing all live.
Results
Fully merged main branch — no open feature PRs blocking production. All 5 CI gates passing: TypeScript, ESLint, unit tests, build, E2E smoke. Stripe billing live and processing test transactions.
Chrome extension functional on LinkedIn, Indeed, and Greenhouse. Three-tier pricing model ready for go-to-market.
A monorepo with a web app and a browser extension, sharing types and utilities, can be built and maintained by a single engineer without sacrificing CI discipline. The citation-grounding architecture is the differentiator — it's what separates Jobpoise from a GPT wrapper with a job-shaped UI.
