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.

Glutinous rice is soaked, steamed, cooled and dusted with powdered ragi, a dry starter cake of moulds and yeasts. Wrapped in leaves or covered, it ferments for two or three days into a soft, sweet, slightly sour and alcoholic paste with its own juice. Made in 5 steps over 9.6 days – 14 days. The longest step, keep cold, takes 7–10 days (Darniadi S. et al. 2023). Rhizopus (about 83 % of fungal reads in tape ketan) and Mucor and Amylomyces rouxii do most of the fermenting.

Tapai is eaten as a sweet paste, not pressed or strained into a drink. Mould and yeast work together on the steamed rice in two to three days, while rice wines go on for weeks.
Tapai contains alcohol, which rises to about 7 % in two to three days. Keep it in the fridge and eat it within about a week.
