Know what you're aiming for
Learning objectives tell you what you should be able to explain, calculate or compare by the end of each chapter, section or part.
How Preplani works
Turn any book, article or video into a learning plan, then actually finish it.
Start with a goal. Add the resources you already have. Preplani breaks it into chapters, sections or parts with objectives, checklists and quizzes, and every task you tick moves you closer to the goal.

One goal, three resources. Tick a task and its chapter, section or part, the plan and the goal update together.
Read-later apps save what you read. Highlighters save what you marked. Neither tells you whether you're getting closer to what you set out to learn.
Preplani starts with why you're learning, not what you're reading. Every book, article and video you add sits under a goal, so all your progress ends up in one place.
Step 01Set a goal
Start with what you want to be able to do
A goal is the subject you're working toward, like “Learn Python” or “Prepare for the PMP exam”. Give it a reason, a category and a deadline if you have one. Everything you add later rolls up here.
- One goal can hold a book, a few articles and a video course
- Optional deadline keeps the pace honest
- New learners set a goal first, so imports always have a home
Free: 5 active goals (8 after the short survey). Premium: unlimited.

Step 02Import a resource
Bring the resources you already have
Add a book file, an article link or a video link to your goal. A four-step wizard takes you from source to finished plan on one page.
- Books: PDF, EPUB, MOBI or AZW, or straight from Google Drive
- Articles: any web URL
- Videos: YouTube and 300+ platforms
- Chrome extension: save the page you're on to a goal in one click
Step 03
AI structure
More than a summary. A plan you can work through.
For every book chapter, article section or video part, Preplani writes what you should be able to do, what to practice, and how to check yourself. Then you edit it before anything is saved.

Find the critical path in practice question 4
Define float in one sentence, in your own words
An activity has ES = 4 and LS = 9. What is its total float?
5 days. Total float = LS − ES.
Which technique adds resources to shorten the critical path?
Crashing. Fast-tracking runs tasks in parallel instead.

Learning objectives
2–3 per chapter, section or part, written with action verbs like explain, calculate, compare.
Checklist items
3–5 concrete tasks for each one, so there's always something to do next.
Quiz questions
2–3 for each one, with answers, to check you really understood it.
Prerequisites
1–3 concepts to brush up on before you start.
Plans are written in the source's own language, and each chapter, section or part comes with an estimated time.
Step 04Work through your plan
Tick tasks. Progress takes care of itself.
Each chapter (books), section (articles) or part (videos) has its objectives, checklist, notes and a short quiz. Ticking an item updates it. When the last item is done, it completes and the plan and goal move with it. No manual updates.
- Attach notes to a chapter, section or part, or to a single checklist item
- Grade yourself on the quiz before moving on
- Open the book, article or video in Read & Watch mode next to your checklist

Batch Normalization
Explainwhy normalizing activations stabilizes training
Implementa BN layer with learnable γ and β
Distinguishtraining-time and inference-time statistics
Insight
Batch statistics add a little noise — that's why BN also regularizes.
Self-check · 1 of 2
Why are γ and β learned instead of fixed?
So the network can undo the normalization when that works better.
Steps 05–06Notes & review
Save what matters. Review what you'd forget.
Notes belong to the chapter, section, part or task they came from. The revision deck brings them back just before you'd forget them.

Step 07See progress
Know what to do next as soon as you sign in
The dashboard shows your next unfinished chapter, section or part, the three plans you touched last, your streak and this week's activity, so you can pick up where you stopped.
- Streak counts days with at least one completed task
- Last 7 days of activity at a glance
- Every active goal with its overall progress
The added value
Built around how skills actually stick
Reading something once rarely changes what you can do. Each part of a plan moves you from knowing about something to being able to use it.
Do something with it today
Checklist items turn reading into small exercises, and quizzes show you what didn't stick yet.
Still know it next month
The revision deck brings your notes back on a schedule, so finishing a book means remembering it too.
Free vs premium
Everything works for free. Premium makes it sharper.
Both plans get the same structure: chapters, sections or parts, with objectives, checklists, quizzes and prerequisites. Premium uses Claude Sonnet 4.6, which writes richer objectives and better questions, especially for technical material.

FAQ
Questions about getting started
Yes. New accounts start by setting a goal, so every resource you add has somewhere to go. Each goal can hold several plans, like a book, a few articles and a video course.
Books as PDF, EPUB, MOBI or AZW, uploaded directly or from Google Drive. Any article URL. Videos from YouTube and 300+ other platforms.
Yes. You see the full structure before confirming, and you can rename, reorder, add or remove chapters, sections, parts and checklist items.
Ticking a checklist item updates its chapter, section or part. When every item is done, it completes on its own, and the plan and goal update with it.
Notes are due for review after a set interval. You go through them one card at a time and they come back on a schedule.
Pick the skill. Bring the resources. Preplani builds the plan.
