Your API keys are pasted across .env files, a Notepad note, and a Slack DM. Kavranta keeps them in one place and links copies together. Change DATABASE_URL once and every env file that shares it updates too. Values stay masked and never enter AI chat; your assistant asks a local broker for names and presence, not the secrets. Example: edit DATABASE_URL in .env, and .env.local and .env.production sync too. Ask an AI to check config and it sees which keys exist, not what they are.
