SumizAI and QOwnNotes side by side: price, licence, platforms and what each one actually does. ## What QOwnNotes is QOwnNotes is a free, open source plain text notepad with Markdown support and a to-do list manager, available on Linux, macOS, and Windows, that has spent over a decade building a reputation as a solid, low-demand tool for people who value control over their own data. The app is designed to work together with ownCloud's notes app, making it a natural choice for people already using that platform to self-host their data, though it works just as well as a standalone notepad with no cloud sync at all. Key features: Notes in QOwnNotes are stored as plain text files with Markdown formatting, guaranteeing they'll remain readable in any other text editor even if the app itself were to stop being developed. A built-in to-do list manager lets you turn note fragments into tracked tasks alongside the rest of the content, with no need for a separate app. ownCloud integration enables two-way syncing of notes across multiple devices through your own, self-hosted server, instead of relying on a commercial third-party cloud. The GPL-2.0 license guarantees the source code stays available for inspection and modification by the community forever. Who it's for: QOwnNotes appeals to people who value the simplicity of a plain text file over a flashy but closed commercial notepad interface. ownCloud users who already self-host their data and want notes to live in the same ecosystem as their files and calendar will find a natural partner here. Developers and open source enthusiasts for whom code transparency matters, along with people who've already lost notes to a commercial app shutting down and are looking for a solution resistant to that scenario, are a key audience for this notepad. Use cases: In practice, QOwnNotes works well as the central notepad for someone running their own ownCloud server at home, where notes sync automatically between a laptop, a desktop, and a phone with no third-party company in the middle. A developer writing technical documentation in Markdown can use QOwnNotes as a lightweight editor integrated with a task system, tracking TODOs directly within note content. Someone archiving notes for decades ahead appreciates the guarantee that plain text files will stay readable regardless of what happens to the app itself. Pricing and business model: QOwnNotes is entirely free and open source under the GPL-2.0 license, with no fees, subscriptions, or feature limits in exchange for financial support. The project's development relies on voluntary contributions from a community of developers and optional donations from users who appreciate the tool, rather than the commercial model typical of most modern notes apps. Limitations and what to watch for: QOwnNotes's interface is functional but clearly falls short of the polish of modern, commercial notepads designed by large UX teams — the priority here is simplicity and stability, not visual flair. Full sync across devices requires your own ownCloud server, which can be an entry barrier for non-technical users needing extra setup beyond the notes app itself. AI notes alongside an existing structure: QOwnNotes has no built-in AI model integration, but since notes are plain text files, pasting a ai notes entry from a conversation with an assistant is as simple as creating a new Markdown file in the right folder — instantly visible in the app's interface and synced through ownCloud along with the rest of your notes. For users collecting ai notes from many conversations with different assistants, this file-based structure makes searching and organizing that content easier later on. What's worth checking before choosing: Before switching to QOwnNotes, check whether you already have (or are willing to set up) your own ownCloud server, if cross-device sync matters to you — without it, the app works as a local notepad on a single computer. Bottom line: QOwnNotes is a proven, open source tool for people who value the simplicity of plain text files and full control over their own sync infrastructure. Anyone who wants ai notes from AI conversations to land automatically in that structure without manually creating files should consider a tool built specifically around that workflow. Over a decade of steady development: More than 100 likes on AlternativeTo for a notepad in a niche dominated by much more recognizable brands shows that QOwnNotes has built a loyal, technical user community over years of consistent, unhurried development rather than aggressive marketing. That longevity is itself an argument — a tool that has survived over a decade without losing developer support offers more confidence it will still be around years from now, unlike many flashy notes startups that disappear as quickly as they appeared. Scripting and customization: QOwnNotes offers the ability to extend functionality through scripts, letting advanced users tailor the app's behavior to their own specific needs — from automatic formatting to integrations with external tools. That flexibility, typical of open source projects built with a technical community in mind, lets QOwnNotes evolve into a highly personalized working environment, something closed commercial apps usually don't offer without official vendor support. Multilingual interface and support: The project, maintained by a community of volunteers from Austria and more broadly from Europe, offers interface translations into multiple languages, and its discussion forums and documentation are actively maintained by users from different countries. For someone who prefers communicating directly with a tool's creators rather than through a formal, official customer support channel, that community structure can be more accessible and faster at resolving minor issues than standard support procedures in commercial apps. Comparison with SumizAI: QOwnNotes and SumizAI share a philosophy of plain text files as the foundation of notes, but differ in where the content comes from. QOwnNotes is a hand-written notepad integrated with your own ownCloud infrastructure. SumizAI generates ai notes automatically from a conversation with an AI model — answers worth keeping land as Markdown files in a vault the user owns, with no manual file creation or naming. Anyone who already has an ownCloud ecosystem and wants to keep notes there will pick QOwnNotes; anyone who wants ai notes from AI conversations to arise without manual work will find SumizAI the better-fitting tool. **Key facts** - Price: Free - License: Open Source - Origin: Austria, EU - Category: Note-taking, Todo List Manager ## 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 QOwnNotes 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. - QOwnNotes is open source (GPL-2.0), and SumizAI is not. If reading the source is what decides it for you, that is a real argument for QOwnNotes. The guarantee SumizAI offers instead is structural rather than legal: the notes are Markdown files in a folder you chose, so they open in any editor whether or not the application is running. - 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. - QOwnNotes also does tasks. SumizAI does not — no boards, no due dates, no projects. It files knowledge, not work. - AlternativeTo lists no mobile version of QOwnNotes. SumizAI runs on macOS, Windows, iOS and Android. - Both are run from the EU: SumizAI's operator is registered in Poland and the servers are in Germany.
