SumizAI and NoteDiscovery side by side: price, licence, platforms and what each one actually does. ## What NoteDiscovery is NoteDiscovery is a lightweight, self-hosted note-taking application that puts complete control over the knowledge base in the user's hands. Instead of relying on a cloud provider storing data on its own servers, NoteDiscovery runs on infrastructure chosen by the user - a personal VPS, a home NAS, or a self-hosting platform such as Cloudron. The project originates from Spain, within the European Union, which matters to many European users and organizations for reasons of data-processing jurisdiction and compliance with local privacy regulations. The application pairs a modern, aesthetically pleasing interface with the deployment simplicity typical of open-source self-hosted tools. Key features and functionality: The central element of NoteDiscovery is its discovery function - the application doesn't just store content, it actively helps surface related entries based on content and context, rather than relying solely on manual tagging and folders. The user interface is designed with readability and speed in mind - a minimalist layout keeps attention on the notes themselves rather than on elaborate menus and side panels. Because the software is open source under the MIT license, the source code is fully available for review and modification, letting technical teams adapt the application to their needs or verify exactly how data is processed. Support for the Cloudron platform significantly simplifies deployment - administrators can install NoteDiscovery with a single click from the Cloudron panel instead of manually configuring a server, database, and reverse proxy. Who it's for: NoteDiscovery is aimed primarily at technical users and IT administrators who already run their own self-hosted infrastructure and want to add a note-taking tool without handing data to an external provider. Small teams and non-profit organizations for whom data privacy is a priority appreciate being able to fully control where their notes physically reside. Self-hosting enthusiasts who run home servers with tools like Nextcloud or Home Assistant can add NoteDiscovery as a natural extension of their ecosystem of private services. Freelancers and consultants working with sensitive client data gain assurance that their notes never pass through third-party servers. Use cases: In everyday work, NoteDiscovery serves as a personal knowledge base - a place for research notes, project ideas, and loose thoughts that over time form a coherent structure thanks to the related-entry discovery feature. Technical teams use the application as internal process documentation, accessible only on the company's internal network, without risk of leakage through a public cloud. IT system administrators keep configuration-change and troubleshooting logs in NoteDiscovery, confident that the history stays under their control even if they switch cloud providers. Home technology enthusiasts use the app as a digital notebook for DIY projects, recipes, or travel plans, hosted on the same server as their other home services. Pricing and business model: NoteDiscovery is fully free and open source under the MIT license, meaning there are no licensing fees for the software itself. The only cost the user bears is the hosting infrastructure - a VPS, a home NAS, or a Cloudron subscription if the user opts for that more convenient deployment path. This business model, typical of open-source projects, lets the community freely develop and audit the code while letting organizations avoid the vendor lock-in characteristic of closed SaaS services. The absence of any paid tier also means all features are available immediately, with no artificial gap between a free plan and a premium one. Comparison with SumizAI: NoteDiscovery and SumizAI represent different philosophies for working with information. NoteDiscovery is a tool for storing and discovering one's own notes, run on private infrastructure, without built-in integration with language models. SumizAI, by contrast, focuses on aggregating and comparing responses from multiple AI providers in one place, as a cloud-based service. Users who value full data sovereignty and are willing to maintain their own server will naturally choose NoteDiscovery to store their notes, while for conversations with AI models and analysis of answers from multiple sources they'll reach for a solution like SumizAI - the two applications can coexist in a daily workflow, each filling a different role. AI notes and a personal knowledge base: People doing intensive research use NoteDiscovery to build a personal archive of ai notes and source material that grows more valuable over time thanks to the related-entry discovery feature - the more ai notes enter the system, the easier it becomes to surface months-old entries that turn out relevant in a new context. Because the application runs locally, on a personally owned server, the ai notes history stays fully under the owner's control even when sensitive material accumulates over the long term. IT teams using NoteDiscovery as an internal wiki appreciate being able to freely search their ai notes archive without the licensing limits typical of commercial cloud tools. For people who combine their work with locally hosted AI models, NoteDiscovery can serve as a complementary ai notes repository alongside the actual answer-generation process - results of conversations with a model can be manually saved as organized notes, building a personal knowledge base over time that is independent of any cloud service. The open source code also lets technically advanced users extend NoteDiscovery with their own scripts to import these notes from other tools, easing migration of an entire archive without losing the structure and context of the entries. **Key facts** - Price: Free - License: Open Source - Origin: Spain, 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 NoteDiscovery 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. - NoteDiscovery is open source (MIT), and SumizAI is not. If reading the source is what decides it for you, that is a real argument for NoteDiscovery. 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 NoteDiscovery 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. - NoteDiscovery can be self-hosted. SumizAI has nothing to host on the desktop — the vault is a folder on your machine — and if you want the model on your own hardware too, a local Ollama is one of the seven providers it speaks to. - AlternativeTo lists no mobile version of NoteDiscovery. 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.
