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.

Ogiri egusi is a pungent, oily seasoning paste from melon seeds. The seeds are boiled to loosen their coats, shelled, boiled again, wrapped in leaves and kept warm for three to seven days while Bacillus bacteria break down their protein and fat and the mass turns alkaline. Made in 6 steps over 3.3 days – 7.3 days. The longest step, ferment warm in the parcels, takes 3–7 days (Oladeji O.A 2025) and runs at 36–40 °C (Oladeji O.A 2025). Bacillus subtilis and Bacillus species (B. subtilis, B. licheniformis, B. megaterium and others) in Nigerian seed condiments generally do most of the fermenting.

Ogiri egusi uses oily melon seeds where iru uses locust beans. The seeds need only short boils, not the long boil that hard locust beans need, and the paste is softer and oilier.
Market ogiri can carry S. aureus, E. coli and Enterobacter, and it is easily colonised by moulds. Aflatoxin B1 was found in nearly half of market samples, some above the EU limit of 2 µg/kg, so start from clean, sound seed and cook ogiri into the dish.
Hazards the sources name: Staphylococcus aureus, Escherichia coli, Enterobacter and Candida albicans, isolated from market ogiri; Aflatoxin-producing Aspergillus; aflatoxin B1 in 48 % of 31 market ogiri samples (3–4 µg/kg) and ochratoxin A in all of them.
Every number is labelled with how it is known. How this atlas is made
Melon-seed ogiri is made by small producers and sold in local markets such as Okitipupa, Ondo State. It remains uncontrolled solid-state fermentation, so the product varies from place to place.
