Never lose the thread of a conversation again. BLUF listens to the conversation you are already in and hands you one short line at a time: what the other person actually means, and where the conversation is going. It is built for the listener. It never tells you what to say. BLUF never records and never stores audio. Sound is held in memory for the moment it takes to read a sentence, then released. Speech recognition and reasoning both run on your iPhone, so nothing about your conversation is uploaded anywhere. WHAT IT DOES One line, not a transcript. The point of what was said, while it is still useful. It stays quiet. No line during small talk. It speaks when there is something worth saying. It holds the details you are most likely to miss: a deadline, a condition, a number. It shows how the talking was shared, as plain arithmetic. WHAT IT WILL NOT DO BLUF reads words. It does not judge mood, does not analyse tone of voice, and cannot tell you whether someone is being honest. That was a deliberate decision, not a missing feature. It is not a recorder, so there is no transcript to keep. It is not a medical device and must not be relied on for medical or legal instructions. HONEST ABOUT THE LIMITS A line reaches you about two to three seconds after the words are spoken, because a sentence cannot be read before it finishes. BLUF can also be wrong, and the failures found in our own testing are published rather than buried. Read them at luminaracorp.art before you rely on it. USE IT OPENLY BLUF is meant to be used in the open, and it ships a line you can send or say so the room knows. Recording and listening laws vary and the law here is unsettled, so telling people costs you nothing. REQUIREMENTS BLUF does all of its work on the device, which means it needs a recent iPhone with Apple Intelligence available. If your iPhone cannot run it, BLUF says so before you are charged. SUBSCRIPTION BLUF Focus is $6.99 per week, billed weekly, or $69.99 per year, billed yearly. TERMS AND PRIVACY Terms of Use (EULA): https://luminaracorp.art/terms Privacy Policy: https://luminaracorp.art/privacy Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel any time in your Apple ID settings.
