FliTree Open the app

A learning tool that files itself.

Ask a chatbot the same thing twice and you get two answers in two chats. Ask FliTree, and it works out where the answer belongs before it writes a word — then puts it there.

The problem

A chat log is a pile, not a place.

Three things go wrong with a chatbot the moment you use one to actually learn something.

  • Ask again, answered again. The same question in a new chat gets a fresh answer, with no memory that you already asked it.

  • Follow-ups fork. A clarifying question opens another chat instead of improving the answer you were reading.

  • Nothing is related to anything. There is no organisation, so two chats on the same subject sit in a list with no sign that they belong together.

How it works

It decides where something goes before it writes it.

1

It reads the tree first

Before generating anything, FliTree looks at the directory structure you already have and decides where the new material should go. Nothing lands loose.

2

It sizes the question, then outlines

It checks the scope of what you asked. A question that needs a whole subject behind it gets an outline — parent topics, subtopics, in the order that teaches it completely — rather than one answer that stops where the prompt did.

3

Follow-ups edit, they don't fork

Ask a follow-up and it changes the content in place. The page you were reading gets better. You do not end up with a second chat that half-repeats the first.

4

Pages get written when you ask for them

The outline can run ahead of the prose. A topic can sit in the tree as a name you have not opened yet, and stay that way until you want it.

Also

Two things you can ask any page for.

Definitions

Ask it to define a term and the definition becomes part of the material.

Quiz yourself

Ask for questions on what you have covered, and check whether it actually went in.
