About
We build tools that show their work.
Lanternfish began in 2023 as a weekend script that answered one question: where did that number come from? The first version searched a team’s wiki and printed the page it found the answer on.
Today teams use it to read what their company has already written. We still hold to the first rule: no sentence ships without a source, because a tool that can’t show its work shouldn’t be trusted with yours.

0
Sentences shipped without a source.
What we believe
Three rules we keep.
01
Cite it.
If we can’t point to a source, we don’t say it. An empty answer is better than a confident guess.
02
Respect every permission.
Your tools already decide who can see what. Lanternfish follows those rules on every question and never gives anyone more access.
03
Keep the work visible.
Receipts, sync status and audit logs are part of the product, so you can always see what was read and why.
