Blitz

Apply faster. Land sooner. Blitz is a Chrome extension that AI-tailors your CV and cover letter for each job (using your own API key), lets you review everything, then fills application forms on major job boards.

Features

• BYOK AI tailoring — Anthropic or OpenAI; your key stays in the browser
• Match score — visual ring + rationale before you apply
• Human-like form fill — Greenhouse, LinkedIn Easy Apply, Indeed, Workday, Lever, Ashby
• Application tracker — status, notes, CSV export
• Bulk job queue — paste URLs, batch-generate applications
• Freemium — 15 free applications; Pro via license key
• Optional cloud sync — encrypted backup across devices (Supabase); API keys stay local (docs/SYNC_AND_AUTH.md)
• Admin dashboard — separate deploy for staff (user / admin / developer roles) — docs/ADMIN_DASHBOARD.md · Deploy commands
• Dashboard — full-tab workspace (DASHBOARD.md)
