SumizAI and ProNotes side by side: price, licence, platforms and what each one actually does. ## What ProNotes is ProNotes extends the functionality of Apple Notes, macOS's built-in notes app, by adding AI support, Markdown formatting, and other enhancements missing from the original Notes app. Instead of forcing the user to migrate their entire notes archive to a brand-new app, ProNotes lets them stay with Notes — with all their history, Apple ecosystem integration, and habits intact — while gaining features Apple doesn't offer natively. Key features: AI support built directly into the Notes workflow lets you generate summaries, improve text, or ask questions about a note's content without leaving the app. Markdown formatting gives access to syntax native Notes doesn't fully support — headings, nested lists, code blocks — which is especially valuable for technical users used to writing in that format. Additional interface enhancements address small but annoying gaps in the original app, like better tag management or faster search. Because ProNotes runs as a layer on top of the existing app, all iCloud sync across Apple devices remains intact. Who it's for: ProNotes appeals to long-time Apple Notes users who have already built up a sizable notes archive and don't want to migrate to a different app, but still feel the lack of AI features or full Markdown support. Developers and technical users writing documentation in Notes will appreciate formatting support the original app doesn't offer. Users deeply embedded in the Apple ecosystem, for whom iCloud sync and system-wide integration are a priority, will find a way to extend the app's possibilities without losing that integration. Use cases: In practice, ProNotes works well for writing technical documentation directly in Notes, where code and nested-list formatting is essential and switching to a separate document app would waste time. Someone keeping a long, sprawling project note can ask the built-in AI for a summary to quickly recall the project's state without rereading everything from scratch. A student taking lecture notes directly in Notes gains access to formatting features that make organizing material for later much easier. Pricing and business model: ProNotes is a paid app available as a one-time purchase with no subscription model. This business model appeals to users who prefer a single upfront cost over recurring monthly fees, especially for a tool that extends the functionality of an already-owned, free system app. Limitations and what to watch for: ProNotes is Mac-only, so the integration doesn't extend the same range of enhanced features to the Notes version on iPhone or iPad. Because the tool runs as a layer on top of an existing system app, its future compatibility depends partly on how Apple develops the Notes app itself in future macOS versions — internal structural changes may require ProNotes updates. AI notes directly in a familiar environment: ProNotes directly addresses the need to tie ai notes to an existing archive — instead of keeping AI-generated notes in a separate app, the built-in AI support lets you create and store such ai notes right alongside the rest of your notes in Apple Notes, keeping one coherent place for all your knowledge. What's worth checking before choosing: Before buying, check whether ProNotes's Markdown and AI features actually cover your specific formatting needs, and make sure you primarily use a Mac, since the extension doesn't work on other Apple platforms. Bottom line: ProNotes is a way to add AI and full Markdown to Apple Notes without leaving a familiar environment and without losing iCloud sync. Anyone who needs a more extensive, portable ai notes archive that goes beyond one company's ecosystem should consider an alternative approach to storing such entries. Extension instead of replacement: ProNotes's philosophy differs from most notes apps, which ask users to fully migrate and abandon their existing tool. Instead, ProNotes works as an add-on that enriches an existing, familiar app, minimizing the barrier to entry — there's no need to learn a new interface or move years of accumulated notes, just install the extension and immediately gain new features right where you already work. Preserving the Apple ecosystem: For many Mac users, a key strength of Notes is its seamless integration with the rest of the system — Siri, widgets, cross-app sharing, watch sync. ProNotes deliberately doesn't interfere with those mechanisms, focusing purely on adding missing editing features, which means the rest of the user experience stays exactly as familiar as before. The risk of depending on Apple's decisions: Because ProNotes isn't an official Apple product, but an independent extension built on top of Notes's internal structure, there's a risk that a future macOS update could introduce breaking changes until ProNotes's developer ships their own fix. That's a typical risk for any tool built as a layer on someone else's product, worth keeping in mind when planning long-term reliance on such an extension. Offline work and access speed: Because Apple Notes works locally with background sync, rather than as an app requiring a constant internet connection, ai notes created with ProNotes's built-in AI remain accessible even without network access — only generating new AI content itself requires a connection, but viewing and editing already-saved notes always works. That's a meaningful difference from cloud-only tools, where losing connection means losing access to saved content entirely. A quiet return to simplicity: After years of experimenting with increasingly elaborate notes apps, some users come back to Apple Notes precisely because it's simple and always at hand on every Apple device — ProNotes lets them keep that simplicity as a foundation, adding only the features that are genuinely missing instead of replacing it with something complicated from the ground up. Comparison with SumizAI: ProNotes and SumizAI represent different philosophies. ProNotes extends the existing Apple Notes app with AI and Markdown, staying within the closed iCloud ecosystem. SumizAI builds ai notes from the ground up as open Markdown files in a vault the user owns, independent of any single platform. Anyone deeply embedded in the Apple ecosystem who wants to keep their existing Notes archive will pick ProNotes; anyone who wants ai notes from AI conversations to land in a fully portable, open format independent of one vendor will find SumizAI the better-fitting tool. **Key facts** - Price: Paid - License: Proprietary - Category: AI Writing ## 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 - Both mention AI. The difference is whose key it runs on: SumizAI never resells inference — you connect one of seven providers (Anthropic, OpenAI, Gemini, Groq, OpenRouter, a local Ollama or your own server) with your own API key and pay that provider directly. Check what ProNotes does with the model bill before comparing prices. - ProNotes is paid software. Compare the two numbers directly: SumizAI is one dollar a month, one plan, and your AI provider bills you separately for the model you chose. - Both keep Markdown, which makes moving between them mostly a matter of copying files. In SumizAI a vault is a directory holding `base.md` — a generated table of contents — and a `notes/` folder with one `.md` file per note. - AlternativeTo lists no mobile version of ProNotes. SumizAI runs on macOS, Windows, iOS and Android.
