Quick Start

Three steps to your first book.

Foldif appears as a small FAB in the corner of every supported AI page. Start here.

1

Pin or fold a conversation

Open any chat on ChatGPT, Claude or Gemini, then click the Foldif FAB. Drop the conversation into a folder, or pin it to the top.

Shortcut:Ctrl+Shift+F
2

Highlight what matters

Select any text in an AI response. Pick a color. Foldif remembers it forever — across reloads, devices and platforms.

Shortcut:H
3

Compile your first book

When you have a handful of highlights, open Book Builder. Drag chapters into order, add a cover, export as PDF or HTML.

The Knowledge Loop

From conversations to a real book.

The differentiator nobody else has: a clean pipeline from a single highlight to an exportable, beautifully laid-out book.

To build a habit, focus on three things: frequency, cue stability, and reward immediacy.

1. Highlight
Five colors. One click. Survives reloads.
“frequency”

Habit science says daily reps beat weekly bursts — try anchoring this to coffee.

2. Annotate
Margin notes that travel with your highlights.
Vol. 1
