SumizAI and Rook side by side: price, licence, platforms and what each one actually does. ## What Rook is Rook is a notes app for Mac built with code in mind — instead of being a general-purpose notebook with optional support for code blocks, Rook puts programming at the center of the experience, offering syntax highlighting, automatic language detection, and graphic themes tuned specifically for reading and writing code. It's a tool for developers who want to keep code fragments, snippets, and technical notes in a place optimized for that specific kind of content, rather than a general notebook that treats code as plain text. Key features: Syntax highlighting with automatic language detection means a pasted code fragment is instantly readable without manually picking a language from a list — Rook recognizes on its own whether it's Python, JavaScript, or something else, and applies the right coloring. Markdown support lets users combine code fragments with descriptive documentation in the same note, especially useful when documenting technical solutions. Fast local storage and full-text search enable instantly finding a specific code fragment among hundreds of saved snippets. Hierarchical organization lets users group notes into folders and subfolders matching a project's structure. Four graphic themes tuned specifically for reading code reduce eye strain during long sessions of reviewing technical fragments. Smart-paste features automatically format inserted text for the note's context, and optional AI integration support opens the door to expanding functionality down the line. Who it's for: Rook appeals to macOS developers who need a fast, local place to save code fragments, terminal commands, and technical working notes. People juggling several programming languages at once appreciate automatic syntax detection, which saves time on every new snippet. Freelancers and technical consultants serving different clients use the hierarchical organization to keep separate note collections for each project. Use cases: In practice, Rook works well for saving useful terminal commands that are easy to forget between work sessions — instead of searching for them again in documentation or terminal history, a developer has them ready in a searchable notebook. A developer solving a recurring code problem saves the working solution as a snippet with a short note on context, so they don't have to solve the same problem again in six months. A team documenting an internal API combines sample code fragments with Markdown descriptions, building an easily searchable technical knowledge base. Pricing and business model: Rook is available for free as a closed-source macOS app. The absence of a subscription model or paid premium features means full functionality — syntax highlighting, search, hierarchical organization — is available right away with no extra fees, a rarity among specialized notes tools aimed at developers. Limitations and what to watch for: The app is Mac-only, so developers working on Windows or Linux have no access to it. The focus on code and snippets means Rook isn't the best choice for keeping elaborate, interlinked text notes in a knowledge-graph style — it's a tool for specific, technical entries, not for building a personal knowledge base with cross-topic linking. A simple but deliberate feature scope: Rook deliberately doesn't try to be everything at once — instead of adding project-management features or version-control integration, it focuses solely on making saving and finding code fragments as fast as possible. That discipline of scope is a common trait of small, niche tools built by individual developers for themselves first, before becoming a product for a wider audience. For many users, it's exactly that simplicity, not a feature list, that drives loyalty to the app through years of daily use. AI notes while coding with an assistant: Rook mentions optional AI integration support, but without a dedicated automatic-save mechanism, developers using AI assistants to generate or explain code paste valuable fragments of the conversation in manually as new notes. Such a ai notes entry — an explanation of a complex regex generated by an AI model, say — lands in the same searchable notebook as the rest of the snippets, but requires manual copying out of the assistant's chat window. Origin and market niche: Rook was built in Morocco, showing that specialized developer tools today come from very different corners of the world, not just traditional tech hubs. Within the snippet-manager category, Rook competes with elaborate code-editor extensions, but stands out as a standalone notes app rather than a plugin tied to one IDE — ai notes and snippets stay accessible regardless of which code editor someone happens to use on a given day. Themes built for long sessions: The four available graphic themes aren't just a cosmetic option — developers spending many hours a day reading code and technical notes notice a real difference in eye strain with well-chosen contrast and a color palette suited to long evening or late-night work sessions. AI notes and folder organization: It's worth planning from the start where in Rook's folder hierarchy manually pasted ai notes from assistant conversations should live — a separate folder for that material, distinct from hand-written snippets, makes it easier later to tell at a glance what was model-generated from what is the author's original solution. What's worth checking before choosing: Before making Rook your main technical notebook, check whether working Mac-only will be a limitation if you also use other systems, and whether a focus on code fragments fits your note-taking style better than a general text notebook would. Bottom line: Rook is a focused, free tool for Mac developers who need a fast, searchable place for code and technical notes. Anyone who wants ai notes from AI assistant conversations while coding to land there automatically, without manual copying, should consider a complementary tool built around that workflow. Comparison with SumizAI: Rook and SumizAI address different kinds of notes. Rook is a specialized notebook for code and technical snippets, free and limited to macOS. SumizAI generates ai notes from any conversation with an AI model — not just technical ones — turning valuable answers into Markdown files in a vault the user owns, accessible regardless of operating system. A developer can use Rook to store vetted, manually chosen code snippets and SumizAI to build a broader archive of these notes covering both technical questions and everything else they ask AI models in daily work. **Key facts** - Price: Free - License: Proprietary - Origin: Morocco - Category: Snippets 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 - Both mention AI. The difference is whose key it runs on: SumizAI never resells inference — you connect one of seven providers (Anthropic, OpenAI, Gemini, Groq, OpenRouter, a local Ollama or your own server) with your own API key and pay that provider directly. Check what Rook does with the model bill before comparing prices. - Rook is free and SumizAI costs a dollar a month after a seven-day trial that takes no card. A dollar is what it costs to run accounts and licences without reselling the model; if free is the requirement, Rook wins that row outright. - 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 Rook. SumizAI runs on macOS, Windows, iOS and Android. - Both search. SumizAI's search reads the whole note — title, summary, body and the original question and answer — rather than titles alone.
