Keeping AI knowledge up to date
AI knowledge is only useful if it is current. Here is how to keep a brain fresh - re-syncing connected sources, re-uploading changed files, and re-indexing - so answers reflect reality.

Create a brainThe fastest way to lose trust in an AI assistant is a confidently wrong answer built on out-of-date knowledge. A brain is not a one-time upload - it is a living asset that needs to track reality. This article covers how to keep a brain current and why freshness is a core part of knowledge quality.
The freshness loop
How to keep sources current
- Connected sources: re-sync a Google Drive folder or a GitHub repository to pull the latest content
- Uploaded files: replace a document when it changes, so the brain does not answer from an old copy
- URLs and notes: update the reference when the underlying page or fact changes
- Ownership: the brain’s owner is responsible for triggering updates when their domain moves on
Why freshness is a quality issue
Out-of-date knowledge does not fail loudly. The assistant still answers confidently - it is just wrong, because the fact it retrieved is no longer true. Treating freshness as part of a brain’s quality, with a clear owner responsible for it, is what keeps the assistant trustworthy over time.
Tie updates to the moments knowledge actually changes - a policy revision, a launch, a reorg - rather than a vague plan to review "sometime". A brain owner who updates on those triggers keeps the whole thing honest.

Create a brainFrequently asked questions
How do I keep a brain up to date?
Keep its sources current. Re-sync a connected Google Drive folder or GitHub repository to pull the latest content, re-upload a file when it changes, and update URLs or notes when the underlying fact changes. The brain re-indexes the updated content so answers reflect the current version.
What happens if a brain goes out of date?
The assistant keeps answering confidently, but from stale facts - which is worse than not answering at all. That is why freshness is a quality issue: a brain with a clear owner who updates it when the underlying knowledge changes stays trustworthy.
Who is responsible for keeping a brain current?
The brain’s owner. Ownership and freshness go together - the owner is the person accountable for re-syncing sources and re-uploading changed files when their domain moves on, so the knowledge does not drift from reality.
