SumizAI and TextTree side by side: price, licence, platforms and what each one actually does. ## What TextTree is TextTree is a local-first writing and thinking tool built for people juggling several strands of text at once — instead of one document at a time, it lets users open and edit several text files side by side, while organizing ideas as visual cards laid out on a canvas. The app runs in the browser but is local by design: data stays on the user's device rather than on a vendor's server. Key features: Folder management keeps related text files grouped together in a structure that mirrors how the user actually thinks, rather than a rigid scheme imposed by the app. Editing multiple text files side by side makes it easier to compare versions, move fragments between documents, and write with the full context of neighboring notes visible on screen. Organizing ideas as visual cards lets users spread loose thoughts across a canvas and group them by theme before they become organized prose. The app's local nature means content isn't uploaded to an outside server for storage, setting TextTree apart from typical cloud notebooks. Who it's for: TextTree appeals to writers and thinkers who need room for the early stage of the creative process — when ideas are still loose and need to be physically (or at least visually) spread out before settling into a coherent text. People working on several documents at once, different chapters of the same piece for instance, will appreciate editing multiple files side by side without switching between browser tabs or app windows. Use cases: In practice, TextTree works well for writing a longer piece split into sections, where the author wants to see a fragment of a previous chapter while writing the next one. Someone planning an article's structure can lay out loose ideas as cards on the canvas, group them by theme, and only then rewrite them as organized text in a separate file. A student preparing notes from several sources at once can keep each source in its own text file, visible next to the main document where the synthesis takes shape. Pricing and business model: TextTree is available for free as a closed-source browser app. No fees and no requirement to create a paid account lower the barrier to entry for anyone wanting to try the tool with no financial commitment — a typical model for smaller, niche apps built more out of passion than an intent to monetize heavily. Limitations and what to watch for: Being available only as an online app means no desktop or mobile version with a native interface, which for some users used to separate apps on each device can be a limitation. The visual card format, while helpful for brainstorming, won't replace a full-fledged editor for people writing very long, linear texts start to finish without a free-arrangement stage. AI notes across multiple files at once: TextTree has no built-in AI model integration, but its architecture of several files open in parallel lends itself well to manually collecting ai notes from different conversations with an assistant — one conversation in one file, another in the next, both visible side by side while synthesizing conclusions. That requires manually copying content from the chat window into the right file, though, with no automatic mechanism to capture a conversation as a ready-made ai notes entry. The canvas as a working notebook: Visual cards in TextTree function much like a physical corkboard with sticky notes — they let users physically move thoughts relative to each other, spotting connections that are easy to miss in a linear document. The same mechanism suits organizing ai notes gathered from several different conversations with an AI assistant — each ai notes entry as a separate card, moved and grouped alongside related topics before it makes it into the final document. Simplicity as a feature: Unlike elaborate notebooks with dozens of features, TextTree stays deliberately simple — text files and cards, no tagging system, no database, no elaborate plugins. For people overwhelmed by the complexity of bigger tools, that simplicity is exactly what they're looking for. What's worth checking before choosing: Before making TextTree your primary writing tool, check whether working entirely in the browser, with no offline mode or native app, fits your working environment, especially if you often work without a stable internet connection. The daily habit of writing things down: Regular use of TextTree builds, over time, a habit of pausing briefly on a thought before it disappears into the day's next tasks. That habit works well regardless of where the thought comes from — a personal reflection or a fragment of an AI conversation worth keeping as ai notes. Anyone who consistently moves such fragments into TextTree builds, over time, a personal archive to return to on the next writing project. No account as a deliberate choice: TextTree requires no sign-up or login to start using it — you open the page and start writing. That approach contrasts with most modern productivity tools, which lead with a registration screen before showing a single feature. For people wanting to quickly try a tool without creating yet another account and handing over an email address, skipping that barrier is a real advantage, even if it also means no cross-device sync without extra setup. Bottom line: TextTree is a lightweight tool for the early stage of writing, combining work across multiple text files with visually arranging ideas. Anyone who wants ai notes from AI conversations to land in such a system automatically, without manually copying between the chat window and a file, should consider a tool built specifically around that workflow. Comparison with SumizAI: TextTree and SumizAI address different stages of working with text. TextTree helps spread out and organize your own, hand-written thoughts early in building a document. SumizAI generates these notes directly from a conversation with an AI model — answers worth keeping land automatically as Markdown files in a vault the user owns, ready for further work, including in tools like TextTree. Anyone who writes a lot out of AI conversations can treat SumizAI as the first step of gathering material, and TextTree as the place where that material takes final shape. **Key facts** - Price: Free - License: Proprietary - Origin: Japan - 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 TextTree 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. - TextTree 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, TextTree wins that row outright. - AlternativeTo's description of TextTree 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. - TextTree runs in the browser. SumizAI is a desktop and mobile application, and on the desktop the vault is a folder on your own disk rather than a document in someone's cloud.
