AFAIK

AFAIK — AFAIK stands for "as far as I know".

In simple English

AFAIK is a handy hedge in Slack: "AFAIK the API doesn't support bulk updates yet." It tells the reader your answer is based on what you know now, so they may want to double-check. It is honest and polite, and it protects you if things have changed. In formal writing, use "as far as I know" or "to my knowledge".

How to say it: People don't say AFAIK aloud. In meetings, say "as far as I know..."

AFAIK full form: as far as I know. Here is how to use it to answer questions when you're not 100% sure.
