README
OmniTool - developed by gksonlabs
**150 developer and everyday tools in one window**, with the full LabsCode editor built in and an AI assistant, Omni Agent, that can run the tools for you.
JSON, regex, hashes, unit and color conversion, a graphing calculator, a to-do list, ping and a process viewer, QR codes, a typing test: every tool has a catalog number from No. 001 to No. 150, and Ctrl+K finds any of them. Ask Omni Agent "generate 10 UUIDs and save them to a file" and it runs the ID generator, shows you the file and saves it only once you say yes.
