SumizAI and Buho side by side: price, licence, platforms and what each one actually does. ## What Buho is Buho is an open-source note-taking app built on MauiKit, a framework developed by the KDE community, and maintained by Nitrux Latinoamericana S.C. — a Mexico-based company also behind the Nitrux OS Linux distribution. The app lets you take quick notes, save links, and create "books" and pages for notes from classes or reading. Key features: Notes are organized into books and pages, giving a simple hierarchy without having to build an elaborate tagging system. Saving links straight into the notebook makes it easy to collect sources while researching without switching between apps. Auto-save on closing the program protects freshly typed content without manually clicking "save." As a MauiKit app, Buho shares a consistent visual language with the rest of the Maui apps and integrates naturally with Plasma Mobile on Linux phones. Who it's for: Buho appeals to Linux users — especially on Plasma and Plasma Mobile — looking for a lightweight notebook integrated with the rest of the system, without depending on web or cloud notebooks from big tech companies. Students taking class notes and anyone wanting to quickly jot down a thought or a link without opening a full text editor will find a tool matched to that scope. Use cases: In practice, Buho works well for quick note-taking during a lecture, for collecting links to articles read throughout the day in one place, and for organizing a whole semester's notes into separate "books" per subject instead of one flat list of everything. Pricing and business model: Buho is entirely free and open source, released under the LGPL v3 license, in line with the model typical of most MauiKit apps and the wider KDE ecosystem. Limitations and what to watch for: The app is available mainly for Linux (desktop and Plasma Mobile) — no native Windows, macOS, or iOS version limits its usefulness for people working across a mixed set of operating systems. As a smaller, niche community project, Buho doesn't offer advanced features like cloud sync or real-time collaboration found in commercial notebooks. AI notes kept in simple "books": Buho has no built-in AI-model integration, but the simple book-and-page structure lets you quickly paste a fragment of an assistant conversation as a ai notes entry and file it under the right subject or topic. That ai notes entry gets saved locally alongside the rest of the notes from that context. MauiKit as the foundation of a consistent ecosystem: Buho is one of several apps built on MauiKit — a UI framework designed so apps look and behave consistently whether launched on desktop, tablet, or a Plasma Mobile phone. For a user, that means learning Buho partly transfers to knowing other Maui apps. What's worth checking before choosing: Before installing, check whether Buho is available in your Linux distribution's repositories or via AppImage if your distro doesn't package it by default. Bottom line: Buho is a lightweight, free notebook for the Linux/KDE ecosystem, organized around simple books and pages. Anyone needing a more advanced place for ai notes from AI conversations available across more platforms should consider a tool with broader platform reach. Comparison with SumizAI: Buho and SumizAI differ in platform reach and where content comes from. Buho is a hand-written notebook available mainly on Linux. SumizAI generates these notes directly from a conversation with an AI model and runs on macOS, Windows, iOS, and Android — answers worth keeping land automatically as Markdown files in a vault the user owns. Anyone who wants a simple notebook integrated with Linux will pick Buho; anyone who wants these notes from AI conversations to build an archive on any platform will find SumizAI the better-fitting tool. **Key facts** - Price: Free - License: Open Source - Origin: Mexico - Category: Note-taking ## 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 Buho 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. - Buho is open source, and SumizAI is not. If reading the source is what decides it for you, that is a real argument for Buho. 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. - AlternativeTo's description of Buho 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.
