SumizAI and TreeProjects side by side: price, licence, platforms and what each one actually does. ## What TreeProjects is TreeProjects is a free notes app for Windows, built to replace an uncontrolled pile of loose files and notes with one searchable, freeform personal knowledge base. The maker's stated promise is simple: productivity within a few minutes of installing, without the long onboarding typical of more elaborate knowledge-management systems. Key features: Freeform, unstructured note organization lets you write down thoughts without a pre-imposed folder hierarchy or rigid tagging system — structure emerges naturally as you work, rather than being designed upfront. The search function scans the entire note database, letting you quickly find a fragment from months ago without remembering which document it's in. A simple, lightweight interface focuses on writing and searching, without a bloated menu of features most users never touch anyway. The app is free and ready to use right after download, with no account registration or a trial period with limitations. Who it's for: TreeProjects appeals to Windows users looking for a simple, free tool for capturing and finding notes without investing time in learning an elaborate system. People tired of a pile of text files scattered across different folders on disk, who want one place for every loose thought, piece of documentation, or idea, find a natural solution here. Users wary of paid subscriptions or cloud accounts will appreciate the simple model of a local, free app. Use cases: In practice, TreeProjects works well for collecting loose notes from daily work — meeting ideas, fragments of technical documentation, reminders for later — without needing to decide in advance exactly where each note should go. Someone running several small projects at once can save notes for each of them in the same database, relying on search instead of manual folder navigation. A freelancer collecting research fragments for different assignments uses TreeProjects as a quick working notebook, returning to it through keyword search. Pricing and business model: TreeProjects is entirely free, available as closed-source (proprietary) software with no charge for download or use. No subscription model and no paid tier means the app's full functionality is available right away, without the free-versus-premium split typical of many modern notebooks. Limitations and what to watch for: Windows-only availability means Mac and Linux users have no access to the app at all, a significant limitation for people working across multiple operating systems. No built-in cross-device sync mechanism means accessing the same notes on a second computer requires setting up an external tool yourself. Closed source code also means that, unlike many competing open source notebooks, there's no way to verify exactly how the app processes and stores data. AI notes without built-in integration: TreeProjects has no built-in AI model integration, so preserving a ai notes entry from a conversation with an assistant means copying a fragment of the response and pasting it directly into the note database, then relying on search to find it again later. With a large number of such pasted ai notes entries, it's worth developing your own way of marking them — a fixed title prefix, for instance — to make them easier to tell apart from manually written notes while searching the database. The philosophy of no structure: Unlike notebooks that force folders, tags, or wiki-style linking, TreeProjects rests on the assumption that text search is a sufficient navigation mechanism, as long as it's fast and reliable. This minimalist approach works well for people who see organizing notes into folders as wasted time — time spent deciding where to file something can instead go toward the writing itself, then simply typing a remembered fragment into search later. A fast start with no entry barrier: Because TreeProjects requires no setup before first use — no accounts, no sync settings, no theme or plugin choices — a new user can start writing notes literally seconds after installing. By comparison, more elaborate notebooks with a plugin ecosystem often need at least some basic configuration before they become genuinely useful in daily work. Risk at large scale: The advantage of a fast start comes at a cost at scale — after a few years of collecting notes with no structure at all, the sheer number of documents in the database can mean even good search returns too many results to quickly find a specific ai notes entry or other record. People planning to build a multi-year archive should consider at least a minimal note-naming convention, despite the lack of an enforced folder structure. Search as the only navigation mechanism: Because TreeProjects has no alternative navigation path besides text search, the quality and speed of that mechanism directly determines whether the app stays convenient as the database grows. AI notes pasted in with no additional marking get searched right alongside everything else, which in practice is usually enough until note counts reach the thousands. What's worth checking before choosing: Before fully switching to TreeProjects, it's worth checking whether freeform, unstructured organization actually fits your working style — for some people it's a liberating simplicity, for others used to folders and tags, it can become a source of chaos once note counts grow large. Bottom line: TreeProjects is a simple, free tool for Windows users who want to start capturing and searching notes quickly with no fuss about setup. Anyone who wants ai notes from AI conversations to land there automatically, organized and tagged, rather than requiring manual pasting and tagging, should consider a tool built around that workflow. Comparison with SumizAI: TreeProjects and SumizAI differ mainly in content source and approach to structure. TreeProjects is a freeform note database the user fills by hand, relying on search instead of hierarchy. 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, with native support across multiple operating systems, not just Windows. Anyone who values the simplicity of a free, local note database on Windows will pick TreeProjects; anyone who wants these notes from AI conversations to arise automatically and be available regardless of operating system will find SumizAI the better-fitting tool. **Key facts** - Price: Free - License: Proprietary - Origin: Poland, EU - Category: 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 TreeProjects 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. - TreeProjects 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, TreeProjects wins that row outright. - AlternativeTo's description of TreeProjects 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. - AlternativeTo lists no mobile version of TreeProjects. SumizAI runs on macOS, Windows, iOS and Android. - Both are run from the EU: SumizAI's operator is registered in Poland and the servers are in Germany.
