What we are building

Record less. Keep what matters.

The whole idea in one sentence: today's tools record everything and clean up later; Cull decides first, and only writes down what everyone agreed to. Not a notetaker, not a dashboard, but the layer that stands between what a machine perceives and what it is permitted to keep, say, and do.

VS
RECORD EVERYTHING, CLEAN UP LATER · the industry today
  • Everything is saved the moment it is captured
  • Every voice is transcribed, consenting or not
  • Voiceprints are kept indefinitely
  • Deletion happens afterward, if ever
  • The original recording still exists somewhere
  • When something goes wrong, the system keeps more
DECIDE FIRST, KEEP WHAT MATTERS · how Cull works
  • Sound and video live only in a seconds-long buffer
  • Each person's consent is checked before anything is saved
  • Non-consenting speech is discarded, never transcribed
  • No voiceprint without separate written permission
  • The unapproved original is never written at all
  • When something goes wrong, the system keeps less, by design

How it works, in five steps:

1 SENSE sound and video arrive in a short-term memory buffer // seconds long, never a disk 2 ATTRIBUTE the system works out who is speaking, live // before a word is transcribed 3 DECIDE did this person consent? what does policy and law say? // answered per speaker, in the moment 4 RELEASE or DESTROY approved speech is saved; everything else is gone for good 5 ATTEST every notice, consent, stop and deletion is written into a tamper-evident ledger
01 · The product
Shipping first for meetings: six promises, each one a feature.

Announce: everyone hears that capture may begin, including late joiners and dial-ins. Ask: one click or a spoken yes, and silence never counts as yes. Decide: each speaker's words kept or discarded, person by person. Obey: anyone can say “Cull.ai, stop,” even a guest with no account. Forget: voice data destroyed when the meeting ends. Prove: a one-click report of exactly what happened.

02 · The artifact
The document nobody else can produce.

The compliance report: who was told, who agreed, what was kept, what was destroyed, all verifiable, none of it editable after the fact. A general counsel's first question is “how do I prove this?” Our answer is a document they can hand to a regulator, not a promise on a policy page.

03 · The demo
Ten seconds, live.

Kill the process mid-meeting: zero recoverable audio or transcript of any non-consented speaker. That is the patent choke point, running in front of you. Watch it →

04 · The moat question
Why the big AI labs will not build this.

Their business runs on holding data; our promise is that the vendor holds nothing, inside the customer's walls, even offline, even on a robot. They optimize the cloud API; our system works with the network cable pulled. No large lab wants recording-law liability in fifty states. And every improvement in their models makes our layer cheaper and sharper: foundation models are our input, not our rival.
