## Meaning

AFAIK stands for "as far as I know". It means you believe something is true, but you are not completely sure.

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".

## When you hear it

A new teammate asks in Slack whether the staging server resets every night, and you think it does but have not checked recently.

## Examples

- **answering a question in Slack:** "AFAIK the old endpoint still works, but it's deprecated."
- **in a code review:** "AFAIK this library is no longer maintained. Maybe worth replacing?"
- **in a planning call chat:** "AFAIK the design isn't final yet, so let's not estimate it today."

## What native speakers say

- "AFAIK, staging resets every night."
- "AFAIK nobody is working on that ticket."
- "Not AFAIK, but check with Priya."

## Common mistakes

- ✗ "AFAIK I am sure the deploy finished." → ✓ "The deploy finished. / AFAIK the deploy finished." (AFAIK means you're not fully sure. Don't combine it with "I am sure".)
- ✗ "As AFAIK, it's fine." → ✓ "AFAIK, it's fine." ("As far as" is already in AFAIK.)
- ✗ "AFAIK (in a client contract email)" → ✓ "To my knowledge, the integration supports SSO." (AFAIK is chat shorthand. Write it out for clients.)

## Be careful

AFAIK is a hedge. If the answer really matters, check and confirm instead of guessing.
