How it works
Three steps to a cited answer.
01
Connect your tools.
Pick your sources. Lanternfish syncs in minutes and keeps every permission.
02
Ask like you’d ask a colleague.
No query language, no prompt tricks. Type the question the way you would say it out loud.
03
Check the receipts.
Every sentence links to where it came from, so you can verify in one click.
Features
Built for answers you can defend.
