SumizAI and TriliumDroid side by side: price, licence, platforms and what each one actually does. ## What TriliumDroid is TriliumDroid is an unofficial Android client for Trilium Notes — the open-source notebook with a hierarchical note tree covered earlier in this catalog. The app isn't a standalone notebook; it's a mobile window onto the same data store a user runs on a Trilium server (their own or self-hosted) — it lets you browse and edit the note tree from a phone instead of being limited to the desktop version alone. Key features: Access to the full note tree from a phone lets you browse the hierarchy built on a computer without moving content into a separate mobile app. Editing notes on the go syncs with the same Trilium server the computer connects to, so changes show up on both sides almost immediately. Distribution through F-Droid, a store for open-source Android apps, means no dependency on Google Play and a smaller footprint of data collected by the app. The simplicity of the mobile interface focuses on readable browsing and quick edits rather than replicating every desktop feature. Who it's for: TriliumDroid appeals to existing Trilium Notes users who want access to their note store from a phone as well as a computer. People self-hosting their own Trilium server, who value full control over their notebook's infrastructure, naturally reach for this client to close the last gap — mobile access — without handing control over to an outside cloud service. Use cases: In practice, TriliumDroid is useful for quickly adding a thought to an existing branch of the note tree while away from home, instead of waiting to get back to a computer. Someone maintaining project documentation in Trilium can check the details of a specific note during a meeting outside the office, with a phone instead of a laptop at hand. A user self-hosting a Trilium server on their own NAS or VPS connects to it through TriliumDroid from anywhere with internet access, keeping full ownership of their data. Pricing and business model: TriliumDroid is free and open source under the AGPL-3.0 license, same as Trilium Notes itself. No fees, subscriptions, or ads — the app is maintained by the community around the Trilium project, and its development depends on volunteer developer contributions. That model is typical of unofficial mobile clients built around a larger open-source parent project. Limitations and what to watch for: As an unofficial client, TriliumDroid may not keep up with every new feature introduced in the main desktop version of Trilium — some advanced capabilities, like scripts or elaborate views, tend to be available only on the computer. The app requires a running Trilium server to connect to — on its own, it isn't a standalone offline notebook without an already-configured backend. Distribution through F-Droid also means updates can arrive with a delay relative to releases on GitHub, depending on that particular store's publishing process. AI notes on a mobile device: TriliumDroid has no built-in AI model integration, but it lets you add ai notes from conversations with an assistant straight from your phone into the same hierarchy maintained on the computer — just copy a fragment of the conversation from a mobile AI assistant app and paste it in as a new note in the right tree branch. That works, but it stays entirely manual — there's no automatic mechanism that captures an AI conversation and saves it as a ai notes entry without copying and pasting. Unofficial status as a deliberate choice: The fact that TriliumDroid is an unofficial client rather than a product from the same team as Trilium Notes is sometimes mistaken for a weakness — in practice it reflects a typical development model for AGPL projects, where different parts of the ecosystem (server, desktop client, mobile client) can be maintained by different people drawn from the same community. For the user, that means the quality and pace of the mobile app's development depend on the activity of a specific group of volunteer developers, independent of what's happening with the main server project. Privacy as a side effect of architecture: Because TriliumDroid connects directly to a Trilium server chosen by the user rather than a central service controlled by the app's makers, the privacy of notes depends entirely on where and how that server is hosted. For people self-hosting their own infrastructure, that's a major advantage — no third party has visibility into note content, including any ai notes pasted in there from conversations with AI assistants. It's also worth remembering that the more devices connect to the same server — phone, tablet, computer — the more important it becomes to properly secure the server itself, since it, not the individual clients, is the single point every piece of data passes through. What's worth checking before choosing: Before relying on TriliumDroid as your main way of accessing notes on the go, make sure your Trilium server is reachable from the internet securely (through a VPN or an HTTPS reverse proxy, for instance), since the mobile app connects to the same backend as the desktop version. The daily rhythm of switching devices: In practice, many Trilium users develop a natural division of labor: longer editing sessions and building out the tree structure happen at the computer, while TriliumDroid mainly handles quick additions and browsing throughout the day. That split works well, since a phone's smaller screen isn't ideal for browsing an elaborate hierarchy with many nesting levels at once, but is more than enough for jotting down one thought or checking a specific note. Bottom line: TriliumDroid is a practical bridge between the elaborate, hierarchical Trilium notebook and everyday life with a phone in your pocket. Anyone who wants ai notes from AI assistant conversations to land in the note tree automatically, rather than through manual copying from a phone, should consider a tool built around that workflow. Comparison with SumizAI: TriliumDroid and SumizAI solve different problems within the notes ecosystem. TriliumDroid gives mobile access to an existing, manually built note tree in Trilium. SumizAI generates ai notes directly from a conversation with an AI model, saving them as Markdown files in a vault the user owns, regardless of whether the conversation happened on a phone or a computer. Anyone who already has a Trilium store and wants phone access will pick TriliumDroid; anyone who wants ai notes from AI conversations to arise automatically, without manual copying between apps, will find SumizAI the better-fitting tool. **Key facts** - Price: Free - License: Open Source ## 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 TriliumDroid 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. - TriliumDroid 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 TriliumDroid. 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. - AlternativeTo's description of TriliumDroid 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.
