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.

Cereals and bread from Gujarat, India
Split Bengal gram (chana dal) and rice are soaked, ground separately and mixed into a batter that ferments with no added starter. The risen batter is steamed open in a greased pan into a spongy, mildly sour cake, then tempered with mustard seed and cut. Made in 5 steps over 36 h – 38 h. The longest step, soak the dal and the rice separately, takes 18–20 h (Sharma A 2018) and runs at 16–23 °C (Sharma A 2018). Salt is 0.8 % (Sharma A 2018). Leuconostoc mesenteroides and Enterococcus faecalis do most of the fermenting.

Total time across the recorded steps: 36 h – 38 h
What changes: Water soaks into the dal and rice and softens them
Output: soft, swollen grains.

Dhokla is made like idli, but with Bengal gram (chana dal) in place of black gram, and the batter is steamed open in a flat pan instead of in covered idli moulds.
In the optimisation study, fermenting raised the biogenic amine content of the batter, and steaming for 20 min lowered it again, so the batter is always steamed before eating.

A dish called dukkia appears in a Jain text of 1066 CE, and the word dhokla in the Varnaka Samuchaya of 1520 CE.
