Before you start.
Does MasterTells join my calls?
No, by design. No stranger in your meeting, and your audio never leaves your devices. Record on your iPhone or Mac, or import the transcript your call already made.
What is a tell?
A pattern in how someone communicates: a strength or a blind spot, backed by the moments it happened. It can show up in one conversation and be confirmed across many. There's no fixed list: MasterTells finds and names each one in your own conversations.
What is a recap?
A short summary of every conversation, ready in seconds: what it was about, what was decided, what was left open, and who committed to what.
Does it work for in-person conversations?
Yes. Put your iPhone on the table and tap Record: meetings, one-to-ones, team talks and family dinners alike.
Can I import from Zoom, Google Meet or Teams?
Yes, and from Webex, Otter.ai, Rev, WhatsApp, Slack and more. Import a call's transcript or captions, a chat export, or a Word, PDF or text file.
Can I share what MasterTells finds?
Yes. Turn any conversation into a polished PDF report, or share a single section as a PDF or text.
Which languages does it understand?
English, Spanish, French, German, Italian, Portuguese, Japanese, Korean, Chinese and Cantonese.
Who can see my conversations?
Only you and the people you share them with. Not even MasterTells can read what you store.
What do I get for free?
Recaps for 5 hours of conversation a month, unlimited recording and transcription, and basic stats. No credit card needed.
How are hours counted?
Each conversation counts its words at 150 a minute, or its recording's length if shorter, and at least 5 minutes. Failed analyses count nothing, a recap comes free with Tells, and unused hours of Tells carry over.
What if I forget my password?
Signed in on your iPhone, change it in Account › Password and recovery. On a new iPhone, iCloud Keychain and a code sent to your email let you in, or your 12-word recovery phrase. If all are lost, nothing can be recovered: the keys never reach MasterTells.
How do I delete my account?
In the app, open Account, then Delete account. Transfer the spaces you share first, or they're deleted for everyone. Nothing readable is left, not even in backups. It can't be undone.
