SumizAI and Notedrafts side by side: price, licence, platforms and what each one actually does. ## What Notedrafts is Notedrafts is a note-taking app built for people who don't want to choose between writing, drawing, and working on a large canvas — instead of three separate tools, they get one that moves smoothly between document types. Notedrafts adapts to the way you work: one moment it's marking up and commenting on a PDF, another it's sketching on a sprawling canvas that scrolls in any direction, and another still it's writing in a long, vertical layout reminiscent of a classic notebook. The app is available on Mac, making it a tool for people already working in that ecosystem who want one place for several forms of note-taking. Key features: PDF annotation lets users highlight passages, add margin comments, and draw arrows pointing at specific spots in a document, invaluable when reviewing long source material. A large, flexible drawing canvas breaks free of a single page's limits — users can stretch a sketch in any direction, building a mind map or diagram with no boundaries set in advance. The long vertical note layout resembles a traditional lined notebook and suits classic, sequential writing where the order of thoughts matters. The ability to mix drawing with text in one document lets users combine hand-drawn sketches with typed text without switching between separate apps. Who it's for: Notedrafts reaches students taking lecture notes that combine text and diagrams, designers sketching visual ideas alongside written descriptions, and people reviewing PDF documents who want to leave comments directly on the source material. Anyone working with a tablet or stylus on a Mac will find Notedrafts a natural tool for handwritten work paired with classic text note-taking. Use cases: In practice, Notedrafts works well for reviewing a PDF contract and marking clauses that need a lawyer's attention, with comments placed directly next to the relevant paragraphs. Designers sketch an interface layout on a large canvas, adding text notes alongside explaining the reasoning behind each decision. Math or physics students combine handwritten equations with a step-by-step text explanation in a single document. People preparing a presentation sketch an initial storyboard on the canvas before turning it into finished slides in another tool. Pricing and business model: Notedrafts runs on a freemium basis — the basic version is available at no cost, with limits on document count or canvas size, while full functionality requires a paid subscription. This setup lets users try all three working modes (PDF, canvas, vertical notebook) on real documents before deciding to invest in the paid tier. Limitations and what to watch for: Being Mac-only means people working across multiple platforms — combining a Windows computer with an Android phone, say — won't find a consistent cross-platform experience here. The flexibility of three distinct note-taking modes (PDF, canvas, notebook) is also a strength and a weakness at once — without consistency in which mode is used for what, material can end up scattered across different formats inside the same app. Fitting into AI conversations: People using AI assistants to analyze PDF documents often first ask a model to summarize or explain a difficult passage, then move the conclusions as ai notes directly into an annotation at the relevant spot in the document in Notedrafts. The app itself has no built-in AI assistant, so such ai notes have to be pasted in by hand after the conversation wraps up in a separate tool. What's worth checking before choosing: It's worth checking how Notedrafts exports mixed documents combining drawing and text — not every export format keeps both elements fully readable outside the app itself. It's also good to test performance on very large PDF files before building an entire document-review workflow at work around it. Bottom line: Notedrafts is a solid choice for Mac users who want one tool for text notes, PDF annotation, and hand-drawn sketches. Anyone who wants ai notes from AI assistant conversations to land in an archive automatically, rather than through manual copying, should consider pairing Notedrafts with a tool built specifically around that workflow. Comparison with SumizAI: Notedrafts and SumizAI differ fundamentally in where a note starts. Notedrafts starts from a document — a PDF, a canvas, or a blank page — that the user fills with content. SumizAI starts from a conversation with an AI model, where answers worth keeping automatically become ai notes saved as Markdown files in the user's own vault. Anyone who needs a rich, visual environment for annotation and drawing on a Mac will pick Notedrafts; anyone who wants ai notes from everyday AI conversations to turn into finished, portable files without manual copying will find SumizAI a more direct solution to that specific problem. Organizing material over time: People using Notedrafts for longer projects — a college semester or a multi-stage document review, say — accumulate dozens of files across three different modes over time. It's worth settling on a simple naming convention early, because mixing PDFs, canvases, and vertical notebooks without any order makes finding one specific note from months ago time-consuming, even with a decent built-in search. Stylus work versus keyboard work: Notedrafts clearly favors stylus or touchscreen finger input for canvas mode — people who type exclusively on a keyboard may find the drawing mode itself less useful and focus mainly on PDF annotation and the vertical notebook, where classic typing works best. That's worth weighing when choosing which device the app will be used on most. Working on the go: For people working away from a desk — on a train, at a conference, between meetings — the vertical notebook and quick PDF annotation tend to work better than the full canvas, which is more comfortable to use on a larger screen in calmer conditions. Many users naturally split their work this way: notes taken on the go land in the vertical notebook, while proper sketching waits until they can sit down at a bigger screen with a stylus in hand. Storage and backup: Since Notedrafts combines three different content types in one app, it's worth checking exactly how its backup mechanism works — whether it syncs automatically to the cloud or requires periodic manual export. Losing months of accumulated PDF annotations and sketches to a missing backup would sting far more than losing a plain text file, so it's worth sorting this out right at the start, before building a large archive of material inside the app. **Key facts** - Price: Freemium - License: Proprietary - Category: Note-taking, Digital Painting ## 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 Notedrafts 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. - Notedrafts is freemium: there is a free tier and a paid one, and the line between them is the thing to read before committing. SumizAI has one plan at a dollar a month, so there is no feature held back for a higher tier — and an unpaid account still opens and exports every vault it already has. - AlternativeTo's description of Notedrafts 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. - Notedrafts offers a visual surface — a canvas, whiteboard or map. SumizAI has no canvas: the structure it maintains is a written table of contents in `base.md`, up to six levels deep, rebuilt as notes arrive. - AlternativeTo lists no mobile version of Notedrafts. SumizAI runs on macOS, Windows, iOS and Android.
