CoworKit analyzes your real conversations and builds an optimized CLAUDE.md from your actual usage patterns — not what you think you do.
Analyze My Chats →Blog posts, Twitter threads, YouTube videos. The knowledge exists but it's fragmented across 100 sources with no structure.
Everyone knows CLAUDE.md matters. Nobody knows what to put in it. The gap between knowing and doing is where productivity dies.
Prompt engineering is 2024. Context engineering is 2026. The model is rarely the bottleneck. Your setup is.
Describe how you work and what you need. Get a structured, scored CLAUDE.md system prompt — tailored to your role, voice, and workflow. Writers, founders, researchers, consultants: it works for all of you.
Pre-built starting points for the most common workflows: daily work assistant, writing & content, research & analysis, learning & study, business strategy. Click once to prefill, then personalize.
Every generated prompt gets scored across five dimensions: clarity, specificity, output format, persona & tone, and constraints. Actionable tips show you exactly what to improve.
Learn how to get dramatically better results from Claude. How to structure your context, set tone expectations, define output formats, and tell Claude what NOT to do. The craft behind the prompts.
CoworKit builds yours in 60 seconds.
Build my CLAUDE.md — it's free →Everything you need to know about CLAUDE.md and Claude custom instructions.
CLAUDE.md is a custom instruction file that Claude reads before every conversation. It tells Claude who you are, how you work, what tone to use, and what kind of output you need — so you stop re-explaining yourself every time you open a new chat.
Think of it as a permanent briefing for your AI assistant. Once it's set, Claude knows your role, your preferences, and your standards without you having to repeat them.
Use the free generator above. Describe your role and how you use Claude — the generator builds a structured, scored CLAUDE.md in under two minutes. No technical knowledge needed.
If you already have a CLAUDE.md, use the "Optimize Existing" tab. Paste your current file, and you'll get a quality score plus a rewritten version with specific improvements.
Easiest: claude.ai Projects. Go to claude.ai → Projects → open or create a project → click "Set project instructions" → paste your CLAUDE.md contents. Claude will use it for every conversation in that project automatically.
Desktop app: Open Settings → "Claude instructions" → paste. Applies to every new conversation.
Quick option: Paste it at the start of any conversation. Claude will follow it for that chat.
Claude ignores instructions when they are too vague, too long, or buried in the conversation. The fix is a well-structured CLAUDE.md placed in your project instructions — it's specific, loaded before every chat, and far harder for Claude to miss than a mid-conversation instruction.
After generating your CLAUDE.md here, score it: anything under 70 usually has missing specificity or unclear output format — both fixable in under five minutes.
CLAUDE.md is a plain-text file that holds your personal system prompt — the persistent context Claude reads before every conversation. "System prompt" is the broader technical term; CLAUDE.md is the file convention used in Claude Projects and the Claude desktop app.
CoworKit generates a CLAUDE.md formatted for direct use in claude.ai Projects, where it has the most impact.
Yes — CoworKit is built for everyday Claude users, not developers. Writers, founders, consultants, researchers, marketers, and students all use it. You describe your work in plain language; the tool handles structure, scoring, and format.
