“The report projects 40% growth in Q3, driven primarily by the new product line.”

— an AI assistant, answering from memory

BrainyKit — answer

Revenue grew 12% in Q3, led by the services segment. [1] The growth follows the pricing change announced in June. [2] Two regions still missed their targets, citing supply delays. [3]

A note from the author —

Thanks for scrolling all the way down. Before you go, three honest tips:

Start small. Make one project from one folder you actually care about — meeting notes, a contract, your thesis sources. BrainyKit is at its best when the stakes are real.

Click the citations. Every claim points back to a passage; the habit of checking is the whole point of the app.

The first model download takes a few minutes. Make tea. After that, everything — asking, highlighting, dictating — works with the network cable unplugged.

If your sources don’t contain an answer, BrainyKit will tell you so. That’s not a bug. That’s the product.
