Overview

HireOS is a bring-your-own-key AI resume optimizer. Users paste a job description and their current resume; the platform rewrites and tailors the resume against the role using the user's choice of AI provider, then renders a clean, ATS-friendly PDF. A companion Chrome extension lets users trigger the flow from any job listing page.

The Challenge

Job seekers apply to tens of roles but manually tailoring a resume for each posting takes 20–30 minutes. Existing tools are expensive subscriptions with locked-in AI providers and no transparency over what model is being used.

Solution

Built a bring-your-own-key model supporting five AI providers (OpenAI, Anthropic, Gemini, Groq, Mistral) — users pay only their own API costs. Cloudflare Workers handle the AI proxy layer for low-latency edge inference. The PDF renderer produces pixel-perfect output with customizable templates. The Chrome MV3 extension auto-fills job context from LinkedIn and other job boards.
