SumizAI and Nottodbox side by side: price, licence, platforms and what each one actually does. ## What Nottodbox is Nottodbox is a free, open-source app from Türkiye that brings together three things many users keep in separate tools: rich-text notes, a to-do list, and a personal diary. Instead of installing three different apps — one for notes, one for tasks, one for a journal — Nottodbox offers one place for all three, available on Linux (including via Flatpak and Flathub), macOS, and Windows. Key features: The rich-text editor supports popular formatting options, so notes can include bold text, lists, headings, and other elements typical of a modern editor rather than plain text alone. Three separate modules — notes, to-dos, and a diary — run within a single app but each keep an organizational structure suited to their type of content. The app is fully open source under the GPL-3.0 license, meaning full code transparency and the option for any interested developer to audit it. Distribution through Flathub and Flatpak makes installation easy across many Linux distributions without manually resolving dependencies. Who it's for: Nottodbox appeals to Linux users looking for a lightweight, open-source alternative that combines notes and tasks without needing separate apps for each. People who value open source software on principle, regardless of specific feature sets, will find a product aligned with that philosophy here. Users keeping a simple diary alongside a task list will appreciate having both coexist in one interface instead of switching between apps. Use cases: In practice, Nottodbox works well for daily planning — a to-do list next to notes with ideas and a short diary entry about how the day went, all visible in one place without switching windows. A Linux user who installs software mainly through Flatpak will appreciate that Nottodbox is natively available there, without fiddling with packages outside the official repository. Someone migrating from closed, commercial notes apps to a fully open-source software stack will find Nottodbox one piece of that migration. Pricing and business model: Nottodbox is entirely free and open source under the GPL-3.0 license — there are no fees, no premium plans, and no feature restrictions tied to payment. That model is typical of community projects, developed more out of a need for a specific tool than an intent to build a commercial business around it. Limitations and what to watch for: As a smaller, niche open-source project, Nottodbox lacks the extensive documentation and large support community found in more well-known notes apps, so troubleshooting may require reading the source code directly. The absence of a native mobile app limits use to desktops and laptops, with no quick way to jot a note down from a phone on the go. AI notes while working on Linux: Nottodbox has no built-in AI model integration, but users running locally hosted AI assistants on Linux — a common scenario in this community, which values independence from commercial cloud services — can manually paste interesting fragments of conversations in as ai notes entries in Nottodbox's notes module. That manual process fits the app's philosophy: full user control over what goes into their notes and how, without automatic integrations tied to external, often closed AI services. What's worth checking before choosing: Before committing to Nottodbox as your main tool, check the current state of development on its repository — how often updates and bug fixes land, which in smaller open-source projects tends to be uneven over time. Bottom line: Nottodbox is a free, open-source combination of notes, tasks, and a diary for Linux users who value independence from closed software. Anyone who wants ai notes from conversations with a local AI assistant to land there automatically has to rely on manual copying instead, since the app has no such integration built in. The philosophy of one simple tool: Many notes apps grow over time to include dozens of features rarely used by the average person — integrations, plugins, advanced formatting options. Nottodbox stays deliberately modest: three modules, a clearly defined purpose for each, with no ambition to become a sprawling productivity platform. For some users that modesty is a feature, since it means a shorter learning curve and less risk of the app becoming too complicated to want to use every day. Community and project development: Like many smaller open-source projects, Nottodbox develops through the contributions of a small group of enthusiasts rather than a team employed by a commercial company. That means the pace of new features tends to be irregular, but at the same time the direction of development is genuinely shaped by users submitting suggestions directly in the code repository, rather than a marketing department deciding what will sell best. Cross-platform without compromise: It's rare for a smaller open-source project to support Linux, macOS, and Windows simultaneously from the same codebase, but that's exactly what Nottodbox offers. For a user switching between a work computer running Windows and a personal laptop running Linux, that means being able to use the same familiar tool regardless of which machine they're sitting at, without having to learn two different apps. Syncing files between those systems, however, requires your own solution, such as a third-party file cloud, since Nottodbox doesn't offer a built-in cross-device sync service. Why the license matters: The GPL-3.0 license Nottodbox is built on guarantees not just free access to the code, but every user's right to modify and redistribute the app, as long as they preserve the same licensing terms. That's a stronger form of openness than licenses that allow a modified version to be closed off — it means Nottodbox and all its derivatives stay open forever, which for part of the open-source community is a value in itself, independent of the app's specific features. Comparison with SumizAI: Nottodbox and SumizAI share an appreciation for simplicity, but differ in where content comes from. Nottodbox is a manually kept, open-source notebook combining three content types in one app. SumizAI generates ai notes directly from a conversation with an AI model — answers worth keeping land automatically as Markdown files in a vault the user owns. Anyone who values full open-source control over every part of their notebook will pick Nottodbox; anyone who wants ai notes from AI conversations without manual copying will find SumizAI the better-fitting tool. **Key facts** - Price: Free - License: Open Source - Origin: Türkiye - 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 Nottodbox 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. - Nottodbox is open source (GPL-3.0), and SumizAI is not. If reading the source is what decides it for you, that is a real argument for Nottodbox. 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 Nottodbox 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. - Nottodbox also does tasks. SumizAI does not — no boards, no due dates, no projects. It files knowledge, not work. - AlternativeTo lists no mobile version of Nottodbox. SumizAI runs on macOS, Windows, iOS and Android.
