SumizAI and LynxPrompt side by side: price, licence, platforms and what each one actually does. ## What LynxPrompt is LynxPrompt is a self-hosted and federated platform for AI IDE/tools rules and commands, available via WebUI and CLI. Generate, browse, store, and share AGENTS.md, CLAUDE.md, and more. The application comes from Spain, within the European Union, is fully open source under the Apache 2.0 license, available on macOS, Windows, Linux, as an online service, for self-hosting, and via Docker. Key features and functionality: Federation as the platform's architecture means different LynxPrompt instances can communicate and exchange content with each other, similar to other federated systems, instead of forcing one centralized instance for the entire community. Support for both a web interface and a command line (CLI) gives users flexibility in choosing their preferred way of interacting with the platform, matched to their working style. Generating files such as AGENTS.md or CLAUDE.md supports the growing ecosystem of AI tools using standardized configuration files to define coding assistants' behavior. Browsing, storing, and sharing features for these files create a complete lifecycle for rules and commands - from creation, through archiving, to sharing them with a community or team. Who it's for: LynxPrompt is aimed primarily at developers using AI coding-assistance tools who want to effectively manage configuration files defining those assistants' behavior. Technical teams standardizing how AI tools are configured within their organization use LynxPrompt as a central repository of proven rules and commands. People who prefer self-hosting their infrastructure instead of relying on external commercial services appreciate LynxPrompt's open-source nature under the Apache 2.0 license. Developers sharing their AGENTS.md or CLAUDE.md configurations with the broader development community use the platform's federated architecture to reach users beyond their own local instance. Use cases: A development team standardizing how it works with an AI coding assistant creates a shared AGENTS.md file in LynxPrompt, making it available to every team member through the central repository. A developer looking for proven CLAUDE.md configuration patterns browses the platform for examples shared by other users in the federated network. An organization preferring full control over its infrastructure deploys LynxPrompt on its own server via Docker, instead of using a service hosted by an external provider. A developer working mainly from the command line uses LynxPrompt's CLI interface to quickly generate and manage configuration files without leaving the terminal. Pricing and business model: LynxPrompt is entirely free and open source under the Apache 2.0 license, with no licensing fees for downloading and deploying the platform. This model, typical of open-source infrastructure tools, lets the developer community freely use the platform and contribute to its development, regardless of whether they choose the self-hosted version or the one available as an online service. Comparison with SumizAI: LynxPrompt and SumizAI operate in different areas of the AI tool ecosystem. LynxPrompt is a specialized platform for managing configuration rules and commands for AI coding tools, with no integration with conversational chat. SumizAI, by contrast, is a platform enabling conversations with multiple AI providers at once, unrelated to managing coding assistants' configuration files. A developer using LynxPrompt to manage their AI tools' configuration might additionally use SumizAI when they need general AI consultation not directly related to configuring a coding assistant. AI notes about effective configurations: Developers using LynxPrompt often keep ai notes documenting which AGENTS.md or CLAUDE.md configurations worked best for specific projects, building a library of proven patterns over time to use in the future. The platform's federated architecture means such a ai notes base can draw inspiration from configurations shared by other users across the wider network, extending beyond knowledge accumulated solely within one organization. Teams standardizing their approach to AI tools use ai notes as justification for configuration decisions, making it easier to onboard new team members to already established conventions. The CLI interface means adding further these notes can happen without leaving the terminal, in the same place a developer manages the configuration files themselves. **Key facts** - Price: Free - License: Open Source - Origin: Spain, 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 - Both mention AI. The difference is whose key it runs on: SumizAI never resells inference — you connect one of seven providers (Anthropic, OpenAI, Gemini, Groq, OpenRouter, a local Ollama or your own server) with your own API key and pay that provider directly. Check what LynxPrompt does with the model bill before comparing prices. - LynxPrompt is open source (Apache-2.0), and SumizAI is not. If reading the source is what decides it for you, that is a real argument for LynxPrompt. 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. - LynxPrompt 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 LynxPrompt. 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.
