SumizAI vs Notestudio

What Notestudio is

What Notestudio is

Notestudio is a Spanish handwriting notes app for Mac, iPhone and iPad that combines the charm of traditional handwriting with the capabilities of a digital tool. Instead of a keyboard, the primary input method is a stylus or finger, and the app tries to make that experience feel as close to writing on real paper as possible, with appropriate virtual-pen resistance and natural line behavior.

Key features

Flexible paper styles let you pick a background matched to the kind of note — ruled lines for writing, a grid for technical sketches, a blank page for free-form drawing. Advanced drawing tools include multiple pen widths and styles, an eraser that works precisely on a selected area, and the ability to mix drawing with text on the same page. A smooth, customizable interface lets you adapt the tool layout to your own working style instead of forcing one rigid scheme on every user. The app integrates well with Apple Pencil, using pressure and tilt sensitivity to render handwriting more naturally.

Who it's for

Notestudio appeals to people who think visually and prefer a stylus over a keyboard — designers sketching ideas, students taking notes with charts and diagrams, or artists who want a sketchbook and a notebook combined in one place. People who tried switching to digital notes but missed the physical gesture of handwriting will find a tool built specifically around that experience.

Use cases

In practice, Notestudio works well for sketching a design concept in a meeting, where a drawing explains more than a paragraph of text. A student taking notes in a math lecture can freely mix handwritten formulas with handwritten diagrams, something typing on a keyboard wouldn't allow. Someone keeping a visual journal combines short handwritten notes with quick sketches of what they see around them that day. An architect or interior designer can sketch a preliminary room layout directly on a tablet while talking with a client.

Pricing and business model

Notestudio runs on a freemium model — the basic version is available at no cost, with the option to unlock additional paper styles, tools, or more note storage in a paid plan. That model lets new users test whether handwritten note-taking on a tablet suits them before committing to a full purchase.

Limitations and what to watch for

The app is Apple-only, so Windows and Android users have no access to it. Handwritten note-taking, despite its strengths for sketching, tends to be slower than typing for long text notes, and searching handwritten pages is generally less reliable than searching plain text unless the app offers solid handwriting recognition.

AI notes and handwritten work

Notestudio has no built-in AI model integration, so anyone wanting to keep an ai notes entry from a conversation with an assistant has to handwrite it out or paste it in as a screenshot image, which doesn't play to the app's real strength of drawing. For many users the natural workflow is keeping ai notes from AI conversations in a separate text-based tool, and reserving Notestudio for sketches and notes that genuinely need a hand rather than a keyboard.

What's worth checking before choosing

Before investing in Notestudio, check that your tablet supports a pressure-sensitive stylus — without one, much of the app's appeal doesn't come through. It's also worth testing the free version on a typical note-taking task of your own to judge whether the speed of handwriting on screen works for you.

Bottom line

Notestudio is a solid tool for people who value handwritten note-taking and sketching on a tablet, within the Apple ecosystem. Anyone who wants ai notes from AI conversations to land automatically as ready, searchable text files should look for a tool built around text rather than drawing.

Notebook structure and organization

Notes in Notestudio are organized into notebooks and pages, letting you group related sketches and notes by topic, much like a physical binder holding several notebooks. Switching between notebooks happens with a quick gesture, so moving from work notes to a personal sketchbook doesn't require navigating a complicated menu. The ability to import photos and PDF documents as a page background lets you annotate directly on existing material by hand, for instance marking up corrections on a scanned contract printout.

A daily notation ritual

Many Notestudio users describe their workflow as a return to a handwriting habit they'd missed since the days of paper notebooks — fewer notification distractions, more focus on the thought being written down at that moment. That ritual is especially valued by people who've noticed that handwriting helps them remember a note's content better than typing alone, a finding backed up by independent research on memory retention.

Complementing a digital archive

Someone who keeps a parallel digital text notebook with ai notes generated from AI conversations can treat Notestudio as a complement to that archive — a place for visual notes that would be hard to describe in text alone, like an architectural sketch or a hand-drawn mind map. Pairing two tools this way, one for text and ai notes, the other for drawing, lets each medium do what it does best instead of forcing one app to be everything at once. The ai notes themselves from such a conversation are best kept separately, in a text-based tool, with Notestudio reserved for what text alone can't capture.

Building drawing skill along the way

Regular use of Notestudio also tends to build drawing skill as a side effect of ordinary note-taking — even simple diagrams or arrows connecting ideas grow more precise over time when the tool offers none of the resistance of a physical pencil needing sharpening or an eraser leaving crumbs behind. For people learning conceptual sketching, in a design course for instance, the app can serve as a digital scratchpad where mistakes cost one undo gesture rather than a sheet of paper, a low cost of experimentation that encourages attempts many people simply wouldn't make on paper for fear of wasting it.

Comparison with SumizAI

Notestudio and SumizAI address entirely different note-taking needs. Notestudio is a canvas for handwriting and stylus drawing. SumizAI generates ai notes straight from a text conversation with an AI model — answers worth keeping land automatically as Markdown files in a vault the user owns, with no stylus and no manual retyping. Anyone who sketches and writes by hand will pick Notestudio; anyone who wants these notes from AI conversations to be created automatically as searchable text will find SumizAI the better-suited tool.

What SumizAI is

A note-taking application built around a conversation with an AI model. You ask a question, the answer streams back, and the answers worth keeping become Markdown notes — filed into a vault that is a folder on your own disk.

A vault is a directory holding base.md, a generated table of contents up to six levels deep, and a notes/ folder with one .md file per note. Before a note is written it is checked against the ones already there, so the fourth note about the same idea gets merged instead of added. Links between notes are ordinary Markdown links to files that exist.

The model is never ours: you bring your own API key to one of seven providers — Anthropic, OpenAI, Gemini, Groq, OpenRouter, a local Ollama or your own server — and pay that provider directly. A question sends the table of contents plus at most five relevant notes within a 24,000-character budget, and the app shows you which five it used.

Every answer kept this way becomes one of these ai notes, ready to search again months later without hunting back through old chats.

Side by side

Where they differ

• AlternativeTo's description of Notestudio does not mention an AI model. That is the whole starting point in SumizAI: you have a conversation with a model on your own API key, and the answers worth keeping become notes without you filing them.
• Notestudio is freemium: there is a free tier and a paid one, and the line between them is the thing to read before committing. SumizAI has one plan at a dollar a month, so there is no feature held back for a higher tier — and an unpaid account still opens and exports every vault it already has.
• AlternativeTo's description of Notestudio does not mention Markdown, so check what format your notes end up in before you fill it up. SumizAI writes standard .md files to a folder you picked, and an unpaid account can still export all of them.
• Notestudio supports handwriting or drawing. SumizAI is typed text only.
• Both are run from the EU: SumizAI's operator is registered in Poland and the servers are in Germany.
