The Problem

Every repo holds a product. Most builders never see it.

Developers ship tools that other developers build on top of. Every public repo is a signal — a stack, a capability, a narrative waiting to be extracted. The problem isn't access. It's depth.

Surface-level scanning returns surface-level results. What you need is a tool that actually reads the codebase — structure, patterns, dependencies — and reasons through what it finds before it writes a word.

#2 Mark File

A CLAUDE.md written by extended thinking.

Not pattern matching. Not template filling. The engine uses Claude Fable 5 to understand how your codebase actually works before writing a single line.

→ powered by Claude Fable 5
#3 Build Ideas

Three launch-ready concepts. Every scan.

Each idea comes with a domain, a pump.fun ticker, a value prop, and the build angle — derived directly from what the repo can do. Not generic. Specific to the codebase.

Intelligence Score

Deep repo analysis. In seconds.

MARK doesn't skim. It reads manifest files, scores your stack against 59 curated patterns, and builds a structured intelligence profile before writing a single word.

How it works

From tab open to build idea in thirty seconds.

01 / Scan

Read the manifest

MARK reads package.json, CMakeLists, Cargo.toml — whatever defines the stack. No cloning. No uploads. Server-side in under ten seconds.

02 / Score

Match 59 patterns

Your stack scores against a curated library of 59 skill patterns. The result is a ranked profile of what the codebase can do and how to work with it.

03 / Generate

Two outputs, one click

A production-ready CLAUDE.md drops into your terminal. Three pump.fun-viable utility ideas land in tab two. Rescan any repo, anytime.

Features

Built for the crypto builder workflow.

Every feature is optimised for one thing: getting from "interesting repo" to "live utility on pump.fun" faster than anyone else.

01
Universal

Any public repo

GitHub URL is all you need. MARK works on repos in any language — C++, Python, Rust, TypeScript, Go — and doesn't require a token or install.

02
Instant

30-second full scan

Manifest fetch is parallel. Pattern matching is deterministic. Generation runs on the server. You get results in under half a minute.

03
Structured

CLAUDE.md ready to use

The output isn't a summary — it's a Claude Code context file. Drop it in any repo and Claude understands the stack immediately.

04
Actionable

3 launch ideas per scan

Each idea includes a domain suggestion, pump.fun ticker, value prop, and estimated build time. The angle is always derived from actual repo capabilities.

05
Free tier

5 scans daily, no card

Free to use. No credit card. No account. Rate-limited per IP at 5 scans per 24 hours so it stays accessible without burning API costs.

06
Portable

Download as ZIP archive

One click packages CLAUDE.md, matched skill files, and a setup guide into a ZIP. Everything Claude Code needs to hit the ground running.

Powered by Claude Fable 5 Extended Thinking

Fable 5 thinking. Not a scan. A read.

Most repo tools skim the surface — file names, dependency counts, keyword matches. MARK uses Claude Fable 5— Anthropic's latest and most capable reasoning engine: a mode that thinks step by step, revisits its own conclusions, and builds deep architectural understanding before generating a single word.

The result is a CLAUDE.md powered by Fable 5 extended thinking that Claude Code actually uses — not a generic template, but a file that reflects how your specific codebase works and what your agent needs to contribute.

→ initializing Claude Fable 5 extended thinking pass...
→ Fable 5 analysis: whisper.cpp is a native C++ ggml port, not an API wrapper
→ adjusting build instructions: users must run 'make' first, not npm install
→ Fable 5 reasoning: generating 3 verified utility concepts based on Swift UI & C++ integration
