ContextStack is a visual tool that generates structured Markdown context files for LLM-powered software projects. Help Cursor, Claude, GPT and other AI tools understand your architecture, stack, and coding rules.

LLMs fail when they don't understand your project context. Writing prompts for every request is fragile, time-consuming, and doesn't scale.
Long prompts get truncated, forgotten, or misinterpreted. Your carefully crafted instructions disappear after a few exchanges.
Prompts live in chat history. You can't track changes, share with teammates, or maintain consistency across projects.
Every new session requires re-explaining your stack, conventions, and preferences. That's wasted time and tokens.
Different prompts produce different results. Without shared context, AI outputs vary wildly across your team.
Instead of rewriting prompts, ContextStack generates structured Markdown context files that can be reused, versioned, and shared across LLM tools.
Pick from 180+ pre-configured blocks covering languages, frameworks, patterns, and coding conventions.
Select technologies and rules visually. No more writing lengthy system prompts from scratch.
Export LLM-friendly context files that work with any tool. Version them in Git like any other code.
Generate comprehensive project context in under 2 minutes. Use it across all your AI-powered tools.
Select Frontend, Backend, Fullstack, Mobile, or Data/ML. The interface adapts to show relevant options.
Pick your stack, frameworks, patterns, and coding rules from visual blocks. Configure options as needed.
Download clean, structured context files ready to use with Cursor, Claude, GPT, or any LLM tool.
The generated context files can be used with any tool that supports Markdown context.
ContextStack transforms how developers work with AI coding assistants.
Define what you want, not how the AI should think. Your context becomes a source of truth.
Context files live in your repo. They persist across sessions, tools, and team members.
Track context changes like code. Review, diff, and rollback your project rules.
Everyone uses the same context. AI outputs become consistent across your organization.
Generate LLM-friendly context files in minutes. No signup required.
