# SumizAI vs NeatNotes

Looking for a NeatNotes alternative? SumizAI and NeatNotes side by side: price, licence, platforms and what each one actually does.

## What NeatNotes is

NeatNotes is a free Windows app for note-taking on an infinite canvas, combining handwriting recognition, a math problem solver, PDF annotation, and Obsidian Vault Mirror sync — all running 100% locally, with no cloud and no account required. This approach puts NeatNotes in opposition to most modern notes apps, which by default assume sync through the vendor's cloud — here, data stays exclusively on the user's disk from the very first moment.

Key features:

An infinite canvas lets users freely arrange notes, drawings and annotations across two-dimensional space, without the constraints of rigid pages or linear documents, which works great for visual note-taking and mind mapping. Handwriting recognition turns handwritten notes written with a stylus or mouse into searchable text, especially useful for people who prefer handwriting over typing. A built-in math solver lets users solve equations and math problems written by hand on the canvas, making NeatNotes a practical tool for students in STEM fields. PDF annotation lets users highlight, comment on and draw directly on PDF documents imported into the notes app, with no need for a separate PDF reader and annotator. Obsidian Vault Mirror sync lets the notes app's content be reflected in an Obsidian vault, bridging the world of visual canvas notes with the world of text notes in Markdown format.

Who it's for:

NeatNotes mainly reaches students and pupils, especially in fields requiring written mathematical formulas, who use a tablet or a touchscreen laptop running Windows. It's a tool for people who value privacy and want certainty that their notes never leave the local disk, while still wanting advanced features like handwriting recognition and math problem solving.

Use cases:

A math or physics student can take handwritten lecture notes on a tablet, using the built-in solver to instantly check the correctness of problems being worked through in real time. Someone reading academic papers in PDF can import them into NeatNotes, highlight key passages and add their own comments directly in the document margin. A user already using Obsidian for text notes can add NeatNotes as a complement for visual note-taking, mind mapping and sketching, with content synced to the same Markdown vault.

Pricing and business model:

NeatNotes is entirely free, though it remains closed-source (proprietary) software rather than an open-source project. The complete lack of any fees, combined with full offline functionality and no account requirement, makes NeatNotes a rare example of a fully free, advanced notes app with no hidden subscription model.

Limitations and what to watch for:

NeatNotes is available on Windows only, ruling out Mac, Linux and mobile device users — a significant limitation for anyone working across a multi-platform environment. As a closed product with a like count of zero recorded on AlternativeTo at the time of writing, NeatNotes may have a smaller support community and slower feature development than more established alternatives in the notes app market.

AI notes and NeatNotes:

NeatNotes focuses on visual, handwritten and mathematical notes created directly by the user, not on conversation with an AI model. Anyone who'd like to store ai notes from conversations with assistants like ChatGPT in NeatNotes would have to paste the content of such conversations in manually as plain text on the canvas — the app has no built-in AI model integration or mechanism for automatically creating ai notes from a conversation.

Why locality matters for handwritten notes:

Handwritten notes, especially ones containing math formulas or diagram sketches, tend to be especially personal and detailed — their content often reflects a user's train of thought in a way plain text doesn't capture. Keeping such data purely local, without sending it to a vendor's cloud, is a meaningful security argument for many people, especially when notes relate to research work, unpublished results, or materials under academic confidentiality.

The canvas as a thinking space:

Unlike a notes app built around linear pages, NeatNotes' infinite canvas lets users lay out thoughts spatially — grouping related concepts closer together, drawing arrows connecting different fragments, leaving blank space for later additions. For people whose thinking process is inherently non-linear, that spatial freedom tends to feel far more natural than the rigid page-by-page structure of a typical digital notebook.

Bridging the visual and text worlds:

The Obsidian Vault Mirror feature deserves particular attention, since it solves a real problem for many users combining visual and text note-taking — instead of maintaining two entirely separate note systems, NeatNotes lets users keep one coherent vault where visual canvas notes coexist with text notes in Markdown, accessible through the same Obsidian tool.

What's worth checking before choosing:

It's worth testing handwriting recognition against a sample of your own handwriting, since the quality of this feature can vary depending on a given person's legibility and writing style. It's also worth checking exactly how sync with Obsidian Vault Mirror works, especially if you plan to rely on it as your main way of bridging visual and text notes.

The math solver in practice:

The built-in math solver sets NeatNotes apart from many other canvas-based notes apps — instead of just storing a handwritten equation as a static image, the app can interpret and solve it, turning the notes app from a passive archiving tool into an active math-learning helper. For a student checking their own homework solution or preparing for an exam, this feature cuts the time needed to verify calculation correctness, though it obviously doesn't replace independently understanding the solving method. It's worth remembering this feature has nothing to do with saving ai notes from conversations with language models — it's a separate, dedicated math function.

Bottom line:

NeatNotes is a solid, fully free and local tool for visual note-taking on an infinite canvas, especially valuable for STEM students on Windows. It's a notes app for manually creating content, not for gathering ai notes from AI conversations.

Comparison with SumizAI:

NeatNotes and SumizAI represent different approaches to note-taking. NeatNotes is a local, free visual notes app on an infinite canvas with handwriting recognition and a math solver. SumizAI is a notes app built around conversation with an AI model, where answers worth keeping become ai notes saved as Markdown files in a vault the user owns. Anyone who needs a visual notes app for handwriting and math on Windows will appreciate NeatNotes; anyone who wants ai notes to be created automatically from a conversation with AI will find SumizAI a better fit.

## 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.

## Where they differ

- AlternativeTo's description of NeatNotes 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.
- NeatNotes is free and SumizAI costs a dollar a month after a seven-day trial that takes no card. A dollar is what it costs to run accounts and licences without reselling the model; if free is the requirement, NeatNotes wins that row outright.
- AlternativeTo's description of NeatNotes 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.
- NeatNotes offers a visual surface — a canvas, whiteboard or map. SumizAI has no canvas: the structure it maintains is a written table of contents in `base.md`, up to six levels deep, rebuilt as notes arrive.
- NeatNotes supports handwriting or drawing. SumizAI is typed text only.
- AlternativeTo lists no mobile version of NeatNotes. SumizAI runs on macOS, Windows, iOS and Android.
