SumizAI and Plainva side by side: price, licence, platforms and what each one actually does. ## What Plainva is Plainva is an open-source, local-first editor for plain Markdown vaults, released under the AGPL-3.0 license by a German team. Its main goal is opening existing Obsidian-compatible vaults directly from cloud storage, with no import, conversion, or file migration, while preserving full file ownership for the user. It's a tool for people who want to move away from closed notes apps without abandoning their existing collection of notes. Key features: Plainva opens a Markdown vault directly from a cloud folder (iCloud Drive, Dropbox, or another locally synced drive), without copying files into its own closed format. Obsidian compatibility means plugins, internal links, and the folder structure familiar from that popular notes app work here without extra setup. The app runs on Mac, Windows, and Linux, making it a genuine alternative independent of a single operating system. Open source code under AGPL-3.0 means anyone can verify how the app handles data and submit a fix or even fork the project. Who it's for: Plainva appeals to Obsidian users who want a lightweight, open-source alternative without giving up their existing note vault. People who value full control over their files and are wary of paid, closed notes subscriptions will find a tool aligned with that philosophy here. Developers and open-source enthusiasts who prefer apps with visible source code will appreciate the project's transparency. Use cases: In practice, Plainva works well when someone already has an extensive Markdown vault in Obsidian but wants to try a lighter, open-source editor without migrating files — they simply point it at the same cloud folder. A project team keeping documentation in Markdown files can use Plainva as a quick preview across different computers without installing heavier software. Someone moving from a paid notes app to an open-source setup can keep their existing files without rewriting anything. Pricing and business model: Plainva is entirely free and open source under AGPL-3.0. The absence of a subscription model means the developers maintain the project more out of a passion for local, open note-taking tools than an intent to build a commercial business, which is typical of many projects in this niche. Limitations and what to watch for: The app has no official mobile version, so accessing the vault from a phone requires a different tool or a cloud file browser. Because the project is relatively young and small (zero likes on AlternativeTo at the time of writing), development pace and community support may be slower than with larger, established alternatives. AI notes while working with a vault: Because Plainva works directly on .md files in the cloud, saving a ai notes entry from a conversation with an AI model there is simple — just add a new text file to the vault, and Plainva will show it in its structure as soon as the cloud syncs. There's no built-in mechanism, though, that automatically captures such a ai notes entry from an assistant conversation without manually copying the content. What's worth checking before choosing: Before switching to Plainva as your primary editor, check whether your Obsidian plugins and extensions have equivalents, and make sure your chosen cloud sync service works reliably across all your devices. Bottom line: Plainva is a lightweight, open-source gateway to Obsidian-compatible Markdown vaults, without locking data into one app. Anyone who wants ai notes from AI conversations to land there automatically, without manually saving every file, should consider a tool built specifically around that workflow. The local-first philosophy: Plainva fits into the broader "local-first" movement of tools that reject the model where an app vendor is the sole gatekeeper of user data. Instead, files live wherever the user puts them — on disk, in a cloud they choose, in any version control system — and the app is merely a window for viewing and editing them, not their owner. This philosophy has real practical weight: even if the Plainva project were abandoned, the vault's files would remain fully readable and usable in any other Markdown editor. Project development and community: As a younger, smaller open-source project, Plainva develops at a pace tied to volunteer developer engagement rather than a corporate product's release schedule. For users, that means new features may appear irregularly, but a reported bug or feature request goes directly to the people responsible for the code, without the layers of customer support typical of larger companies. Frictionless trial: The biggest practical advantage of Plainva for someone already using Obsidian is that trying the new editor carries no risk — just point it at the same vault folder, with no export, import, or background file copying. If Plainva doesn't meet expectations, going back to the previous tool is just as instant, because the source files never left their original format or location. Cross-platform consistency: Availability on Mac, Windows, and Linux matters especially for technologically mixed teams, where one member works on Linux, another on macOS, and a third on Windows — everyone can open the same file vault without needing to install different tools depending on the operating system. That sets Plainva apart from many notes apps that treat one operating system as the priority and the rest as an afterthought with limited functionality. For organizations employing developers on different setups, that's a real onboarding time saver — there's no need to document separate installation instructions for each operating system individually. Format as a portability guarantee: Because Plainva doesn't invent its own file format and simply works on plain Markdown, any file from the vault can be opened in any text editor in the world — from a system notepad to a professional IDE. That portability matters long-term: notes saved today will remain readable a decade from now, regardless of the fate of Plainva itself or even the whole category of local Markdown editors. Comparison with SumizAI: Plainva and SumizAI agree that notes should be plain files owned by the user. They differ in where the content comes from — Plainva is an editor for notes the user already has and writes themselves, while SumizAI generates ai notes directly from a conversation with an AI model, turning answers worth keeping into ready Markdown files. Anyone who already has an Obsidian-compatible vault and wants an open-source editor will pick Plainva; anyone who wants ai notes to arise automatically from an AI conversation will find SumizAI the better-fitting tool. **Key facts** - Price: Free - License: Open Source - Origin: Germany, EU ## 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 Plainva 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. - Plainva is open source (AGPL-3.0), and SumizAI is not. If reading the source is what decides it for you, that is a real argument for Plainva. 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. - 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 Plainva. 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.
