SumizAI and Markpad - Markdown Editor side by side: price, licence, platforms and what each one actually does. ## What Markpad - Markdown Editor is Markpad is a simple, lightweight Markdown viewer and editor available on Windows, macOS, and Linux, released under the permissive BSD-3-Clause licence by a Canadian team. Unlike sprawling knowledge-management apps with link graphs and plugins, Markpad focuses on one thing — quickly opening, viewing, and editing individual Markdown files, with no unnecessary interface, database, or cloud sync forcing an account. It's closer to the "small, well-made program" philosophy than to a platform aiming to replace one user's entire notes workflow. Key features: Markpad combines two roles — viewer and editor — in one lightweight app, meaning a Markdown file can be both quickly previewed in rendered form and edited immediately without switching programs or opening a separate window. The "Text Editor" and "Note-taking" categories in the AlternativeTo listing show the app targets both developers editing README files or documentation and people writing personal notes in Markdown day to day. The open BSD-3-Clause licence allows unrestricted use and modification of the code, including in commercial projects, making Markpad an attractive starting point for developers who want to build their own customized editor without writing everything from scratch. Availability across three major operating systems without heavy dependencies means the app launches quickly even on older hardware, where heavier editors can hang. Who it's for: Markpad is a natural choice for developers who need a quick preview of README.md files or technical documentation without opening a full IDE just to check formatting. It also suits people writing simple text notes who don't need advanced features like a database, tagging, or cross-device sync — just fast access to files on disk. Developers interested in open code can treat Markpad as a base for their own experiments thanks to the liberal BSD licence, forking the project for their own needs. Use cases: A typical scenario is quickly checking how a README will look on GitHub before committing — Markpad renders Markdown locally, with no need to push changes to a repository just to see a preview. A technical writer can use the app to draft short documents without the distractions typical of heavier editors with side panels and toolbars. Someone keeping a simple task list or journal in a single Markdown file gets a tool that opens instantly and requires no account setup or configuration on first launch. Thanks to availability on Windows, macOS, and Linux, the same file can be opened across different machines without changing tools or getting used to a different interface. Pricing and business model: Markpad is entirely free and open source under the BSD-3-Clause licence — one of the most permissive open-source licences, allowing commercial use, modification, and redistribution of the code without licensing fees or an obligation to disclose changes. There's no subscription model or premium tier here — the whole thing is maintained as a community project with no pressure to monetize. Limitations and what to watch for: Markpad's minimalism, while its strength, also means the absence of features users accustomed to more elaborate apps might expect — there's no note tagging, no full-text search spanning multiple files at once, no sidebar with a directory tree built into the app. This is a tool for working with individual files, not for managing an entire notes library at once, which for people with hundreds of Markdown files may not be enough without an additional organization system at the file-system level. The lack of a mobile app limits use to desktops and laptops — editing notes from a phone on the go isn't an option. Because the app has no AI layer at all, it offers no ai notes functionality in any form — no summaries, no suggestions, no automatic content tagging. For anyone looking for a full-fledged knowledge-management system with links between notes, Markpad may turn out too simple and works better as a companion to another, more elaborate tool than as the sole home for all notes. What's worth checking before choosing: Before choosing Markpad, think about how many Markdown files you actually have and whether you'll need to search across all of them at once — if so, the editor alone, without an external file system or search tool, may prove insufficient in the long run. Also check the GitHub repository's activity to gauge whether the project is still maintained, since there's no commercial model forcing regular releases. Anyone counting on ai notes built into the editor should assume upfront that Markpad doesn't offer that feature and isn't planning to, since its entire value lies in simplicity. Bottom line: Markpad works great as an "open, check, fix" tool for individual Markdown files, especially in the hands of developers used to fast, lightweight programs. It isn't, however, a platform for building an elaborate knowledge base or for using ai notes functionality — anyone looking for the latter should head straight for tools that combine a conversation with an AI model with automatically saving answers as Markdown files. Comparison with SumizAI: Markpad and SumizAI share Markdown as a common denominator, but they represent different approaches to notes. Markpad is a minimalist tool for manually viewing and editing individual files — there's no artificial intelligence layer, so ai notes functionality doesn't exist within the app itself and would need to be bolted on externally. SumizAI starts from a conversation with an AI model, and answers worth keeping automatically become Markdown files in the user's private vault, with no manual writing. Anyone who needs a fast, lightweight tool for viewing and editing Markdown files on any system will find a solid answer in Markpad; anyone who wants their ai notes to emerge from a dialogue with a language model instead of manual writing will benefit more from SumizAI, while keeping the same open Markdown files on disk, portable between any tools. **Key facts** - Price: Free - License: Open Source - Origin: Canada - Category: Text Editor, 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 Markpad - Markdown Editor 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. - Markpad - Markdown Editor is open source (BSD-3-Clause), and SumizAI is not. If reading the source is what decides it for you, that is a real argument for Markpad - Markdown Editor. 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. - AlternativeTo lists no mobile version of Markpad - Markdown Editor. SumizAI runs on macOS, Windows, iOS and Android.
