Description
SideKick Brain turns the material you trust into something you can ask.
Create a brain, give it sources, and ask it questions. It answers using only the material you gave it, and it shows you which source each part of the answer came from, so you can check it rather than take its word.
WHY IT IS DIFFERENT
Most AI apps answer from everything they were ever trained on, and you cannot tell where any of it came from. SideKick Brain works the other way around. It answers from your material first, cites it, and when your question is not covered it tells you so plainly and clearly labels what follows as general knowledge. It will not put words in a person's mouth that are not in your sources.
WHAT YOU CAN BUILD
A brain about a person you want to learn from, built from their interviews and talks. A brain for a subject you are studying. A brain for your own notes and research, so the thing you read six months ago is still there when you need it. Keep up to three brains and switch between them.
HOW IT WORKS
Create a brain and name it. Add material by giving it a topic to research, or by pasting a link to a page you want it to read. Ask your question. The answer arrives with its sources listed underneath, each with a date.
You can edit a brain's name, persona and style at any time, and delete a brain and everything it learned whenever you want.
FREE
SideKick Brain is free, with three brains. There is nothing to buy inside the app.
PRIVACY
Your brains and the material you add are tied to your account. Questions and sources are sent to AI providers to produce answers, and the app asks for your agreement before your first question.
