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?¹ The first version searched a team’s wiki and printed the page it found the answer on.²

“Searches the wiki, prints the page. That is all it does.”
Today more than 3,000 teams use it to read what their company has already written.³ 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.⁴
