True redaction removes the text and images from the file — not a black box on top. Plus real in-place text editing, fill + sign, reorder pages, and OCR.
LaunchEdit text in place, sign, redact, fill forms, and reorganize PDF files in your browser — all on your device. No upload, no subscription.
Drop two versions of a contract or drawing set. Moved notes read as moves, changed values light up digit by digit, and hidden text is named.
LaunchSide-by-side or overlay PDF diff driven by one engine that reads each file into a structured model — text, vector geometry, images, form fields, annotations — and compares the models. Moves show as moves, edits show only where they happened, and any PDF type works without picking a mode.
Drop a Gerber ZIP, an ODB++ .tgz or an IPC-2581 .xml and inspect every layer — compare revisions, snap-to-pad measure, run DRC and preview the board in 3D.
LaunchOpen Gerber, Excellon, ODB++ and IPC-2581 PCB files. Inspect layers, measure traces, run DRC, export to PNG / SVG / DXF.
Open a .step / .stp part and it measures itself: volume, thinnest wall, draft and undercuts on load, and a hole list with a BOM in one click. Measure, section, export STL.
LaunchOpen a STEP / STP part and it measures itself — volume, thinnest wall, draft and undercut checks on load, plus hole detection with a BOM. Measure, section, export STL. Rust + WASM B-rep kernel, runs in your browser.

Fish and seafood from Korea
pink-grey shrimp in brine; essential kimchi seasoning. Made in 4 steps over 40 days – 5.6 months. The longest step, main fermentation, takes 10 days – 2.6 months (Lee S.H. et al 2014). Salinivibrio, then Staphylococcus and Halomonas do most of the fermenting.

| Temperature | 15 °CMeasured[s1] | Early phase (days 0-10) |
| Acidity | pH 6.7Measured[s1] | Main fermentation |
| tiny shrimp Acetes japonicus (4-6 cm) |
| solar salt |
| Starter: spontaneous |
Total time across the recorded steps: 40 days – 5.6 months
What changes: Solar salt draws water out of the fresh shrimp

32% salt let potential pathogen genera survive; 20% gave off-flavours. Stop low-salt batches within 30-80 days.
