Goodnotes: AI Notes, Docs, PDF

Goodnotes: AI Notes, Docs, PDF analysis by Appwee

I approached Goodnotes: AI Notes, Docs, PDF as a replacement for the loose collection of notebooks, marked-up documents, and study files that usually ends up scattered across a phone or tablet. It is a free productivity app from Goodnotes, built around handwriting, document annotation, organization, synchronization, and AI assistance. That combination makes it more ambitious than a basic notes app, but it also means the best experience depends on how you like to work.

My first impression is that it makes the most sense for people who think visually. If you enjoy writing with a stylus, circling important lines in a PDF, drawing arrows during revision, or keeping separate notebooks for different subjects, the layout feels natural. If you mainly type short reminders and expect instant, frictionless text entry, a simpler notes application may suit you better.

The app is free to download and carries an Everyone age rating. It has passed five million installs, although its average rating sits at 3.4 from roughly thirty-four thousand ratings, so I would not describe it as universally loved. That mixed response is useful context: Goodnotes can be very effective in the right workflow, but it is not automatically the best note-taking choice for every phone, tablet, or user.

What to expect before you start writing

The central idea is a digital notebook that can hold handwritten pages, imported documents, and study material in one place. I found the experience closer to carrying a set of organized binders than to opening a conventional text editor. You create or open a document, write on the page, add marks to existing material, and return to your library when you need another subject or project.

That distinction matters. A traditional notes app usually prioritizes quick typing, checklists, and lightweight reminders. Goodnotes prioritizes the page itself. The page gives handwriting room to breathe, which is especially helpful for mathematics, diagrams, language practice, lecture notes, and planning sessions where a rigid text field gets in the way.

PDF marking is another major part of the experience. Rather than switching to a separate document viewer, I can keep a reading file beside my notes and annotate it in the same general workspace. For a student, that can mean highlighting a passage and adding a handwritten explanation immediately beside it. For someone handling forms or reference documents, it can reduce the need to print pages just to make temporary notes.

The AI element is best treated as an assistant inside a broader note system, not as the reason to install the app by itself. I would use it when I already have notes or documents that need help being understood, organized, or reviewed. I would not expect it to replace careful reading, especially when the source material is technical or when accuracy matters more than convenience.

Goodnotes is available at no upfront cost, with optional in-app purchases ranging from forty-nine cents to ninety-nine dollars and ninety-nine cents per item. That makes it sensible to begin with the free experience and see whether the writing and document workflow actually fits before spending anything. The app was released on August 3, 2023, and supports operating systems from version 9 onward.

Who will get the most from it

I would point first-time users toward this app if they regularly annotate PDFs, keep handwritten study notes, or want one place for several long-running notebooks. It is also appealing to people who dislike the feeling of typing every thought into a small text box. A stylus can make the app feel more immediate, particularly when the goal is to sketch a thought rather than polish it.

It can also work well for a person who moves between planning and reference material. I might keep a meeting outline in one notebook, open a supporting PDF beside it, and write decisions directly onto the page. That is more coherent than taking a screenshot, opening a separate editor, and later trying to remember which file contains the useful comment.

I would be more cautious if your main requirement is a fast, searchable list of short notes. Goodnotes introduces the idea of pages, notebooks, and documents, which is valuable for structured work but unnecessary for a grocery list or a quick password-free reminder. People who prefer keyboard-heavy workflows may also find that the handwriting-first design asks them to adapt rather than simply continue typing as usual.

The first setup: keep it simple

After installing, I recommend resisting the temptation to build a perfect filing system. Start with one notebook for the immediate task that made you download the app. If you are studying, create a notebook for the current subject. If you are testing PDF annotation, use one document that you already understand. This gives you a meaningful way to judge the app instead of spending your first session arranging empty folders.

Before importing a large collection, decide what belongs in Goodnotes and what should remain elsewhere. I prefer using it for material that benefits from visual attention: lecture slides, reading packets, worksheets, diagrams, and planning pages. I would keep tiny temporary reminders in a lighter notes tool if I need them to appear instantly without navigating through a notebook.

The first practical choice is whether you are creating a fresh handwritten page or working on an existing document. For a new page, choose a notebook and begin with a small task, such as writing a short outline or drawing a simple concept map. For a PDF, open a file that you genuinely need to read and mark only the first page or section. This prevents the common mistake of importing everything and then wondering where to begin.

I also suggest testing your preferred input method immediately. Write a few lines, erase part of one line, and add a mark in the margin. That small test tells you more than a long tour of menus. You will quickly learn whether the pen response feels comfortable on your device and whether the controls are easy to reach while writing.

Your first meaningful success

A useful first session should end with something you can use later. My recommended exercise is a one-page reading note. Open a short PDF, mark one important sentence, write a brief explanation beside it, and add a question at the bottom. Then place that document in a clearly named notebook or collection. You have now tested reading, annotation, handwriting, navigation, and organization in one compact workflow.

For a student, the same exercise can become a revision sheet. Read a page of course material, underline the central idea, and write the explanation in your own words rather than copying the source. The value is not merely that the page looks tidy. The act of deciding what deserves a mark and what deserves a note creates a more active study process than passively scrolling through a document.

For everyday planning, try a handwritten weekly page with three sections: things that must happen, things that would be useful, and questions that still need an answer. This is a better test than writing a single sentence because it shows whether you enjoy returning to a page and updating it. If you dislike that process, the app may not become part of your routine no matter how many tools it offers.

One less obvious advantage is the ability to preserve context. A typed note that says “check section two” is easy to forget when separated from the source. A handwritten comment placed beside the relevant PDF passage keeps the reason for the reminder visible. I find that especially helpful when reviewing material after several days, because I do not have to reconstruct what a vague note meant.

Small habits that improve the workflow

Use names that describe the purpose of a notebook, not just the subject. “Biology” is broad; “Biology exam review” tells you why the notebook exists. For work documents, include the project or meeting context. This becomes increasingly important as your library grows, because a handwriting app can become just as cluttered as a desk if every file receives a generic label.

Keep source documents and personal synthesis visibly distinct. I like to annotate the original PDF lightly, then create a separate page for explanations, questions, and conclusions. That two-stage method avoids covering every inch of the source with marks while still preserving the original material. It also makes later revision faster because the summary page contains the ideas I actually need to remember.

Another useful trade-off is deciding when to use handwriting and when to type. Handwriting is excellent for diagrams, calculations, quick emphasis, and thoughts that are still forming. Typed text is better for long explanations that you expect to edit repeatedly. Treating Goodnotes as handwriting-only can make longer projects tiring; treating it as a normal word processor misses much of its appeal.

I would also use AI after I have created a reasonably clear body of notes, rather than asking it to rescue an unstructured pile of fragments. A focused set of pages gives assistance something more useful to work with. I still compare any generated help with the original document, especially for study material, because convenience should not replace checking the source.

Where new users commonly feel confused

The biggest adjustment is understanding that the app is organized around documents and pages rather than a single endless stream. If you are used to opening one search box and typing, the library can initially feel like an extra step. I found it easier once I stopped trying to make every note live in the same place and instead gave each ongoing activity its own home.

PDF annotation can also create confusion about what has actually been changed. A mark written on a page may look like part of the document while remaining an annotation layered over it. For that reason, I recommend keeping the original file untouched when it matters and using a working copy for heavy markup. That simple habit protects you from turning a clean reference document into a page covered with temporary comments.

Synchronization is another area where expectations should be realistic. The appeal of using the app across devices is obvious, but a workflow that depends on current copies should be checked rather than assumed. When I finish an important set of notes, I make sure the latest version is visible where I expect it before deleting or reorganizing anything elsewhere. This is a sensible precaution for any app handling valuable documents.

Handwriting recognition and AI help can make notes more useful, but they do not remove the need for clear input. Sloppy writing, unusual symbols, crowded diagrams, or highly specialized terminology can produce results that need correction. I see these tools as time-savers for reviewing and reshaping material, not as a guarantee that every handwritten page will become perfect searchable text.

The purchase options deserve attention too. The app is free to try, but optional items can cost anywhere from forty-nine cents to ninety-nine dollars and ninety-nine cents. I would not buy anything during the first few minutes. First create a notebook, annotate a real document, return to it later, and decide whether the workflow has earned a place in your routine.

How it compares with familiar alternatives

Compared with a basic phone notes app, Goodnotes offers a more deliberate visual workspace. The ordinary notes app wins for speed: open it, type a sentence, close it. Goodnotes wins when the note needs a page, handwriting, document context, or a longer life. I would keep both types of tool available rather than forcing every reminder into a digital notebook.

Compared with a word processor, Goodnotes feels better for marking up existing material and mixing writing with sketches. A word processor remains stronger for long, polished documents with extensive editing. If your final output must be a carefully formatted report, I would draft the structure in the tool that handles text best and use Goodnotes for research notes, visual planning, or source annotation.

Compared with a paper notebook, the app is easier to search, duplicate, organize, and connect with digital documents. Paper still has a wonderfully immediate feel and never asks about file organization or purchases. Goodnotes is most convincing when your work already begins with PDFs or needs to travel with you digitally. If you rarely handle documents and simply enjoy writing on paper, the switch may not offer enough benefit.

Compared with a dedicated PDF reader, Goodnotes is more useful when reading and responding are part of the same task. A specialized reader may feel leaner for simple viewing, while this app earns its space when you want to write, highlight, and build study material around what you read. That difference is the key question: are you only consuming documents, or are you actively working on them?

A realistic day-to-day example

Imagine preparing for a class or work presentation. I would import the reference PDF, skim it once, and mark only claims that need explanation. On the next pass, I would write short comments beside those passages, then create a separate page containing the main points, unresolved questions, and a rough speaking order. Finally, I would use the notes as the basis for a short rehearsal rather than rereading the entire source.

That workflow shows where the app is stronger than a loose set of screenshots. The source, reactions, and summary remain connected. If I later remember only part of an argument, I can return to the marked passage instead of searching through a camera roll. The app does not do the thinking for me, but it makes the trail of thinking easier to preserve.

For a less academic example, I might use it to plan a home project from a reference document. I can mark the relevant measurements, sketch an arrangement, and keep a checklist on a neighboring page. The benefit comes from combining visual notes with the document that prompted them. A plain checklist would be faster for simple errands, but it would not hold the same context.

Who should skip it

I would skip Goodnotes if you want a minimal, text-first app for fleeting reminders or if you strongly prefer a physical notebook and rarely work with digital documents. I would also hesitate if your projects require extensive collaborative editing in the style of a shared word processor. The app’s strengths are personal organization, handwriting, annotation, and study-oriented review; they should not be confused with every kind of document work.

It may also be a poor fit for someone who expects AI to produce reliable answers without checking the underlying notes. The assistant can be useful as a second pass, but the responsibility for understanding and verifying important material remains with me. Students should be especially careful not to turn convenient summaries into a substitute for reading.

Finally, consider your device and input preferences. The minimum supported operating system is version 9, but compatibility alone does not guarantee a comfortable writing experience. If your screen feels cramped or your stylus control is awkward, the page-based design may become frustrating. Try a small real task before committing to a large archive or an optional purchase.

My next-step recommendation

Start with one notebook, one genuine PDF or planning task, and one finished page. Do not measure the app by how many tools you can find. Measure it by whether you can return to your work later and understand what you wrote, why you wrote it, and where the supporting document belongs.

After that first success, build a modest structure around your actual routines: one place for study, one for active projects, or one for documents you annotate often. Add AI assistance only when it solves a clear problem, such as turning a dense set of notes into review prompts or helping you inspect material you have already read. This keeps the advanced features useful instead of distracting.

My overall view is positive but selective. Goodnotes is a capable digital notebook for people who want handwriting and documents to live together, and its five-million-plus install base shows that this style of work has a broad audience. The 3.4 average from about thirty-four thousand ratings also reminds me that the experience can be uneven depending on expectations, device, and workflow.

I would recommend giving it a focused trial rather than making a blind commitment. If your first annotated page feels more natural than your usual screenshot-and-notes routine, you have found a strong reason to keep using it. If typing quick reminders remains faster and clearer, there is no need to force a handwriting-centered app into your day. The best reason to choose Goodnotes is not the number of features; it is the way it keeps active thinking attached to the pages and documents that matter.
