SumizAI and Zettlr side by side: price, licence, platforms and what each one actually does. ## What Zettlr is Zettlr is a free, open-source writing platform that brings together note-taking, academic citations, LaTeX and Word templates, and the Zettelkasten method for building a linked knowledge base, all in one place. The app was built for people writing academic texts and long documents — from a single note to an entire book — without switching between a separate citation manager, a word processor, and a notes app. Key features: Zotero integration lets users insert academic citations directly while writing, without manually copying footnote numbers or formatting a bibliography. LaTeX and Word templates allow exporting the same document to a format suited for a journal submission or to a plain Word file for a collaborator who doesn't know LaTeX. The built-in Zettelkasten method lets users link short, atomic notes to each other, building a network of connected ideas instead of a linear document. Snippets speed up typing repetitive elements, and code syntax highlighting makes writing technical documentation inside the same tool easier. Multi-language support and a choice of themes, including dark mode, adapt the interface to individual preferences. Who it's for: Zettlr mainly appeals to researchers, PhD students, and students writing papers that require rigorous source citation, as well as technical writers combining prose with code fragments. People who prefer the Zettelkasten method for organizing thoughts but don't want to give up the ability to export to LaTeX or Word for formal publication find a rare combination of both worlds in Zettlr. Use cases: In practice, Zettlr works well for writing a doctoral dissertation, where hundreds of Zotero citations need inserting throughout the writing process, and the final document has to go to LaTeX matching the university's template. A researcher collecting notes from papers they've read can link them with the Zettelkasten method, building a map of the literature they later draw on when writing the actual text. A technical writer documenting a software project combines prose with highlighted code fragments in one document, exporting finished documentation to Word format for the team. Pricing and business model: Zettlr is completely free and open source under the GPL-3.0 license. The code is publicly available, letting the community submit fixes and extensions, and giving users confidence the app won't disappear from the market because of one company's business decision. The complete absence of fees makes Zettlr accessible to students and researchers on a tight software budget. Limitations and what to watch for: The wealth of academic features — citations, LaTeX templates, Zettelkasten — means a steep learning curve for anyone looking for a simple notes app without such ambitions. Zotero integration requires configuring both tools beforehand, which can be a barrier for less technical users. Exporting to LaTeX assumes at least a basic familiarity with that typesetting system if you want to customize the template to your needs. AI notes in academic work: Zettlr has no built-in AI model integration, so a researcher wanting to keep a ai notes entry from a conversation with an assistant — a paper summary generated by a language model, say — has to copy it manually into a new note and link it to the rest of the material themselves using the Zettelkasten method. For anyone regularly using AI for preliminary literature analysis, that means an extra, repeatable step for every new ai notes entry. What's worth checking before choosing: Before switching to Zettlr, check whether the LaTeX template required by your university or target journal is compatible with the app's export, and test the Zotero integration on a small sample of citations before building an entire larger writing project on top of it. Bottom line: Zettlr is a rare combination of a Zettelkasten notebook with full support for academic writing — citations, LaTeX, and Word export. Anyone who wants ai notes from AI conversations to land in that knowledge base automatically should consider a tool built specifically around that workflow. Project structure as a file tree: Zettlr organizes notes as plain Markdown files in a folder structure the user designs themselves — there's no hierarchy imposed from above. For a large research project, that means keeping separate folders for literature, personal notes, and chapter drafts, while Zettelkasten links still connect everything regardless of where a file physically sits on disk. Anyone who also collects ai notes from AI conversations can keep them in a dedicated project folder, still linking them into the rest of the material with the Zettelkasten method. Export as a bridge between worlds: Being able to export the same document to LaTeX, Word, or a plain PDF makes Zettlr act as a bridge between the academic world, which demands formal templates, and everyday writing, where ease of composition matters most. An author can write in simplified Markdown through the whole creative process and only generate a format-compliant version right before submission. AI notes collected along the way then become ordinary source material, just like the author's own notes. Community and long-term support: Zettlr is developed by an active community of volunteer programmers and researchers who use it daily, which translates into regular updates and quick responses to bug reports. That continuity matters especially for academic users whose writing projects — dissertations, books, long-term research — span years, and whose tool needs to stay stable and supported the whole time, without the risk of a commercial company suddenly shutting the product down. Migrating from other notes apps: Because Zettlr works on plain Markdown files, moving an existing collection of notes from another file-based notes app — Obsidian, say — usually comes down to copying the folder and opening it in Zettlr, with no content lost. Internal links in Zettelkasten format may need minor syntax adjustments, but the note content itself stays fully readable and editable from the first moment after migration. It's worth backing up the whole folder before the first open in a new tool, just in case of unexpected differences in syntax handling — the process itself usually takes a few minutes even with thousands of existing notes, far less than migrating from tools built on closed databases, where export is often incomplete. Zettlr, thanks to relying on an open file format, simply doesn't have that problem. Comparison with SumizAI: Zettlr and SumizAI both respect open text formats, but serve different purposes. Zettlr is an elaborate environment for writing long, formally cited academic documents, built by hand by the author. SumizAI generates ai notes straight from a conversation with an AI model — answers worth keeping land as Markdown files in a vault the user owns, without citations or LaTeX templates, but without manual retyping either. A researcher writing a paper in Zettlr can use SumizAI alongside it to collect quick ai notes from AI working sessions, which they later fold into the main document by hand. **Key facts** - Price: Free - License: Open Source - Origin: Germany, EU - Category: Note-taking, Text Editor ## 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 Zettlr 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. - Zettlr 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 Zettlr. 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 Zettlr 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. - Zettlr is described in terms of linking notes together. SumizAI links them too, but deliberately without a syntax of its own: a link is an ordinary Markdown link, `[Title](file-name.md)`, and the model may only point at a file that actually exists. There are no wiki-style `[[…]]` links to lose on export. - AlternativeTo lists no mobile version of Zettlr. SumizAI runs on macOS, Windows, iOS and Android. - Zettlr's description mentions searching the web. SumizAI does not browse: the material a question can draw on is your own vault — the table of contents plus at most five notes — and whatever the model already knows. - Both are run from the EU: SumizAI's operator is registered in Poland and the servers are in Germany.
