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.

Soft drinks from El Salvador
Atol shuco is a slightly sour atol of fermented dark 'negrito' maize from El Salvador. It is seasoned with salt, alguashte (ground squash seed), cooked beans and chilli and served in a gourd. Only a press account of one San Salvador stall describes it; no study of its fermentation was found.
A short entry: the sources we found record only what is said here about Atol shuco itself. Its own sources do not record how it is made, so the steps and scenes below are those of Atole agrio (sour atole), the closest documented soft drinks ferment, shown as a guide to the method, not as a record of Atol shuco.
| Fermented 'negrito' maize | [s1] |
| Salt | [s1] |
| Alguashte (ground squash seed) | [s1] |
| Cooked beans | [s1] |
| Chilli, to taste | [s1] |
Total time across the steps of Atole agrio (sour atole): 2 days – 6 days
What changes: Maize soaks for days and lactic bacteria sour it
Output: soured, softened kernels.

The only source read describes it as a fermented-maize atol served with beans, alguashte and chilli, and gives no process to compare with other sour maize drinks.
Every number is labelled with how it is known. How this atlas is made
A San Salvador stall, La Zarquita, began almost three decades ago when the mother of the Lozano sisters started selling atol shuco in Plaza Gerardo Barrios; the sisters say the recipe came down from her and their grandmother (El Diario de Hoy, 8 March 2026).
