30-second silent screen recording, looped: drop a sample file → the three-panel result appears → open the QC breakdown → Copy. Poster frame: the result view.

Drop. Inspect. Export.

1 · Drop anything

Notebooks, Word, slides, spreadsheets, PDFs, emails — several at once. Parsing happens in your browser; your files never leave it.

2 · Inspect the fidelity report

Original, Markdown, and a report of what was detected — counts, warnings, a weighted eight-check QC score. Silent loss becomes visible loss.

3 · Export for the destination

Token-lean chat paste, RAG chunks with stable anchors, Obsidian callouts, or a faithful archive — with exact token counts on demand.

media slot · fidelity tour

15-second clip: the fidelity panel up close — counts count up, the QC breakdown expands, one warning is read.

What’s really inside your files

One guide per format — the file’s anatomy, what breaks when a model reads it raw, and the exact element mapping applied.

From the Context Lab

Field notes on feeding documents to LLMs — measured, honest, reproducible.

The lecture notes that made a smaller model smarter

Same workspace, same questions — the only change was PDF → Markdown. A case study with numbers.

case study

LLMs don’t just read Markdown — they speak it

Ask a model anything: it answers in headings and code fences. Feed its native register back.

The ten rules the converter encodes — usable by hand, linkable in reviews.
