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.

Alcoholic drinks from Vedic India
Surā is the grain drink of the Vedic texts, brewed for rituals such as the Sautrāmaṇī. A ritual manual of about 500 BC has cooked rice mixed with powdered sprouted barley, sprouted rice, popped rice and nagnahu, heaped around a drainage frame in a jar for three nights, then strained. McHugh reads it as a semi-solid malt brew that was not distilled.
A short entry: the sources we found record only what is said here about Surā itself.
| Rice paddy, half pounded and cooked wet, half parched | Parched grains that burst are lājā (popped rice)[mchugh2021] |
| Sprouted barley (śaṣpa), powdered1 measure | [mchugh2021] |
| Sprouted rice (tokman), powdered2 measures | [mchugh2021] |
| Popped rice (lājā)3 measures | [mchugh2021] |
| Nagnahu, powdered4 measures | Bought ready-made; a later section of the text glosses it as urad lentils[mchugh2021] |
| Starter | malt for saccharification, perhaps also a complex ferment starter (nagnahu, kiṇva) |
Total time across the recorded steps: 3 days
What changes: Starting materials: sprouted barley, sprouted rice, rice paddy and powdered nagnahu
Output: sprouted barley and rice, paddy, powdered nagnahu.

Surā is the grain drink of the Vedic texts, brewed for rituals such as the Sautrāmaṇī. A ritual manual of about 500 BC has cooked rice mixed with powdered sprouted barley, sprouted rice, popped rice and nagnahu, heaped around a drainage frame in a jar for three nights, then strained. McHugh reads it as a semi-solid malt brew that was not distilled. Made in 6 steps over 3 days. The longest step, heap the mash around the kārotara and leave three nights, takes 3 days (McHugh J. 2021).

Surā combines malt (sprouted barley and rice) with an added ferment powder. It ferments as a semi-solid mash rather than a liquid wort, and it was not distilled.
Every number is labelled with how it is known. How this atlas is made
The Ṛgveda mentions surā, and Vedic ritual manuals describe brewing it for the Sautrāmaṇī. The recipe used here is from the Baudhāyana Śrauta Sūtra, thought by many scholars to date from about 500 BC.
