Feature-by-feature
Simplify focuses on job search automation: its Copilot Chrome extension autofills applications on LinkedIn, Indeed, and Glassdoor, while the AI resume builder tailors resumes to job descriptions and provides an ATS score with missing keyword identification. The job tracker bookmarks roles from 50+ job boards, and the networking copilot finds hiring managers to send emails. GitBook, in contrast, is a documentation platform with a block-based visual editor and bi-directional Git Sync. Its standout features include GitBook Agent (proactive stale content detection and editing, Ultimate plan), AI Assistant (embeddable Q&A chatbot, Ultimate+), and AI Insights (analytics on user/agent queries). GitBook auto-generates API docs from OpenAPI specs and supports MCP server for AI agent interoperability, llms.txt, and Google OKF standards. While Simplify aids active job hunting, GitBook ensures documentation is always current and consumable by AI agents.
Pricing compared
Simplify is entirely free, with no premium tiers—ideal for budget-conscious job seekers. GitBook operates on a freemium model: its free tier restricts to 1 user, making it impractical for teams. Paid plans start at $8/user/month for Premium (includes AI search) and scale up to Ultimate (around $12/user/month) and Ultimate+ (custom pricing), which unlock GitBook Agent, AI Assistant, AI Insights, and integrations. GitBook also charges per word for translations on Premium but includes them on Ultimate. For teams, costs can add up with per-site plus per-user pricing, while Simplify's zero cost is unbeatable for individuals.
