ParseCraft
Document intelligence: align existing converters, parsers, and OCR/VLM models behind one workflow and one typed output format
ParseCraft is a thin aggregation and alignment layer for document intelligence. Capable converters, parsers, and OCR/VLM models already exist, but each emits a different shape — and many ship demo-grade wrapper code pinned to an outdated Python version and dependency set. ParseCraft keeps every tool isolated behind a backend, translates its output into a single typed intermediate representation (IR), and projects that IR to deterministic Markdown. You get one workflow and one output format, while every heavy runtime stays optional.
The IR is the source of truth. Backends read a document and produce typed pages and chunks; every rendering — Markdown today, HTML/JSON/consumer trees later — is a projection of that same IR, never parsed back into state.
Requirements
- Python 3.13 (GIL only — the free-threaded
3.13tbuild is not supported) - Python 3.14 or newer, including free-threaded builds (
3.14t) - uv (recommended) or pip to install the package
Install and Quick Start
Install the released package and list the available backends:
uv add parsecraft # or: pip install parsecraft
uv run parsecraft backends
First release: 2026.9.2. The current version is on
PyPI.
Building from a source checkout, running the test suite, and working on the codebase are covered in the development setup.

# No backends registered. (no third-party backend installed yet)
See the CLI reference for every command, flag, exit code, and environment variable.
How it works
source document → backend (analyze / convert) → typed IR → Markdown projection
- Backends are the extension point. A third party ships a
BackendFactoryunder theparsecraft.backendsentry-point group; the core package does not change to add one. - One typed IR.
DocumentResult,PageResult, andStructuredChunkmove between layers, and Markdown is a deterministic, dependency-free projection. - Heavy runtimes stay optional. Model weights, CUDA, and OCR/VLM stacks load only inside a backend factory, so importing ParseCraft stays offline-clean.
- Failures are typed. A failed pass records a
PassFailurerather than silently dropping a page.
Continue with the architecture overview, the IR model, the backend catalog, and the backend authoring guide.
