Fluent now has 70 lessons across 8 modules — and every core lesson is free, forever.
Two new modules just launched:
- Module 0: Foundations of Agentic Engineering (10 lessons) — tool-agnostic principles every developer needs: how LLMs work, instruction file architecture, context window management, prompt engineering for code, agent steering, reviewing AI-generated code, cost and token economics, security, and the AI-native developer mindset.
- Module 7: Cross-Tool Literacy (6 lessons) — the AI coding agent landscape beyond Claude Code: Cursor deep dive, GitHub Copilot workflows, open-source agents (Aider, Cline, Continue), the AGENTS.md universal standard, and multi-tool workflow patterns.
Both modules are fully translated into English, German, and Hebrew.
The core course is free. All 70 lessons, terminal simulations, quizzes, code playgrounds, progress tracking, streaks, and badges — no paywall. Fluent Pro adds power tools on top: MCP ecosystem, CLAUDE.md linter, code review training, skill assessment, cost & context control, showroom publishing, spaced repetition, and more.
