hibi

Product Introduction

1. Definition: Hibi is a free, open-source, cross-platform desktop application for writing and note-taking, categorized as a local-first knowledge management and document editor. It operates directly on files within a user's local filesystem.
2. Core Value Proposition: Hibi exists to provide writers, developers, and knowledge workers with a highly customizable and flexible writing environment that prioritizes user control, data ownership, and extensibility beyond standard markdown editors. Its primary value is combining the organizational approach of apps like Obsidian with the powerful, plugin-driven editing experience of a code editor like VSCode, all while keeping user data in local folders.

Main Features

1. Local-First File Management: Hibi does not use a proprietary database or cloud sync as its primary storage. It reads from and writes directly to markdown and other text-based files in user-designated folders on their computer. This enables seamless integration with existing file structures and version control systems like Git.
2. Multi-Format Document Support: While markdown is a core format, Hibi's architecture supports writing, editing, and live-previewing documents in other markup and typesetting languages through its addon system. This includes technical formats like Typst and LaTeX for academic writing, and MDX for developers.
3. Extensible Addon System: Functionality is modular. The app ships with core features, but users can enable, disable, or install community-built addons to introduce new tools, themes, syntax highlighting for languages, export capabilities, and workflow integrations. This allows users to tailor the editor from a simple writing pad to a powerful documentation workspace.

Problems Solved

1. Pain Point: The lock-in and lack of control associated with cloud-based note-taking apps (e.g., Notion) or apps that use proprietary data vaults. Hibi solves the problem of data portability and long-term access.
2. Target Audience: Technical writers, developers documenting code, academics writing papers, fiction/non-fiction authors, and AI power users who need to manage prompts and context files. It targets users comfortable with file systems who reject vendor lock-in.
3. Use Cases: Writing a novel where chapters are separate markdown files; maintaining developer documentation that can be exported to a static site; drafting a LaTeX academic paper alongside research notes; creating a centralized workspace for managing system prompts and outputs for various AI agents.

Unique Advantages

1. Strengths & Limitations (Pros & Cons):

   • Pros: Complete data ownership and portability (files are plain text). High degree of customization via open-source code and addons. Free and open-source software (FOSS) with no pricing tiers. Low barrier to entry for users familiar with markdown and file explorers.
   • Cons: Currently in alpha stage, meaning it may have bugs, instability, and missing features compared to mature alternatives. Requires user comfort with manual file management. As a hobby project, development pace and support may be inconsistent. The addon ecosystem is nascent compared to established platforms.

2. Key Alternatives & Differentiation:

   • vs. Obsidian: Both are local-first, markdown-centric knowledge bases. Differentiation: Obsidian focuses on linking notes (graph view) and has a massive, mature plugin community. Hibi differentiates by emphasizing a flexible, editor-first experience for a wider variety of document formats (Typst, LaTeX) out of the box and positions itself as a writing app first.
   • vs. Visual Studio Code: Both are extensible, open-source editors. Differentiation: VSCode is an Integrated Development Environment (IDE) optimized for coding. Hibi is a streamlined derivative focused purely on the writing and document editing workflow, with pre-configured setups for authors and non-developers.
   • vs. Typora: Both offer clean, live-preview markdown editing. Differentiation: Typora is a closed-source, paid editor focused exclusively on markdown. Hibi is free, open-source, and uses an addon system to support multiple markup languages and tool integrations, positioning itself as a more extensible workspace.

Frequently Asked Questions (FAQ)

1. Is Hibi really free, and what is the catch? Yes, Hibi is completely free and open-source software (FOSS) published under the MIT license. There is no subscription, premium tier, or planned monetization. The "catch" is that it is alpha software, meaning users may encounter bugs and should not rely on it for critical, stable production work.
2. Where are Hibi notes stored, and how do I back them up? Hibi notes are stored as standard markdown (.md) or other text files in the folders you open within the app. Backing up is as simple as using your preferred method (e.g., cloud sync like Dropbox, version control with Git, manual copying) on those folders, as Hibi does not manage storage.
3. Can I use Hibi for academic writing with citations and equations? Yes, through its addon system. Hibi supports LaTeX, a standard for academic typesetting. You can write LaTeX documents directly and use its syntax for equations. For advanced bibliography management, you would typically compile the LaTeX externally, as Hibi acts as the editor, not a full LaTeX compiler suite.
4. How does Hibi compare to using a full IDE like VSCode for writing? Hibi provides a more focused and pre-configured environment for writers. It reduces the configuration overhead by centering on document formats and writing tools, whereas VSCode requires significant extension setup and is cluttered with development-centric features. Hibi offers a streamlined user experience tailored for non-programming writing tasks.
5. Is Hibi suitable for team collaboration? Not directly within the app. Since Hibi works on local files, collaboration must be managed externally using tools like Git for version control, Nextcloud for file sync, or by sharing folders on a network. It lacks built-in real-time co-editing or cloud-based sharing features found in apps like Notion or Google Docs.
