Imagine a tool that turns your scattered ideas, notes, and projects into a connected web of knowledge that sharpens your thinking every time you open it.
In 2026, Obsidian stands out as one of the most loved note-taking tools globally, used by knowledge workers, creators, and researchers who demand privacy, flexibility, and deep customization in managing their information.
I’m Riten, founder of Fueler, a platform that helps freelancers and professionals get hired through their work samples. This article walks you through Obsidian’s usage, revenue, valuation, and growth in 2026 using a mix of confirmed data and carefully framed estimates.
Note: Obsidian is a private, bootstrapped company that does not publicly disclose most of its financial and user metrics. Wherever exact data is unavailable, estimates are clearly labeled and should be interpreted directionally. The estimates are derived from community discussions, third-party datasets, and SaaS benchmarking comparisons.
Obsidian is a local-first, Markdown-based note-taking and knowledge management app designed to give users full ownership of their data while enabling powerful interconnections through backlinks and graph views.
Unlike cloud-first tools, Obsidian stores notes locally as plain text files. This ensures that users retain complete control over their data without being locked into proprietary formats.
It is widely praised for its flexibility and plugin ecosystem, making it suitable for everything from personal journaling to complex research systems and second-brain workflows.
Bidirectional linking
Obsidian allows users to create two-way links between notes, enabling a web-like structure of knowledge. This helps uncover relationships between ideas and supports non-linear thinking.
Graph visualization
The graph view provides a visual representation of all notes and their connections. It allows users to identify clusters of ideas and navigate their knowledge base intuitively.
Extensive plugin ecosystem
Obsidian has a large and active plugin ecosystem with over 1,000 community-built plugins. These extend functionality across task management, spaced repetition, publishing, and automation.
Local-first storage
All notes are stored locally as Markdown files. Users can choose how and where to sync, ensuring full ownership and portability of their data.
Cross-platform support
Obsidian works across Windows, macOS, Linux, iOS, and Android, offering a consistent experience across devices.
Obsidian does not publish official user metrics. However, based on publicly available insights such as community size, plugin downloads, and public mentions, it is estimated that:
Unlike typical SaaS tools, Obsidian’s growth is not driven by paid acquisition. Instead, it relies on:
Users often build large knowledge vaults containing thousands of notes, supported by fast search and performance even on local storage.
It is important to note:
What is widely observed, however, is high user depth. Users tend to integrate Obsidian deeply into their workflows, which naturally increases long-term retention.
Geographically, Obsidian has strong adoption in North America and Europe, with increasing traction in Asia and South America, particularly among technical and research-oriented users.
Community discussion also highlights a key differentiator:
Even if the company disappeared, users retain full control of their data (Reddit Discussion)
Obsidian follows a freemium model.
The core product is free, and revenue is generated through optional paid services.
Obsidian Sync
End-to-end encrypted syncing across devices
Obsidian Publish
Allows users to publish notes as websites
Commercial License
Required for business and organizational use
Obsidian does not publicly disclose its revenue.
Any numbers available online are third-party estimates and vary significantly.
Based on multiple sources and SaaS benchmarking:
What is confirmed:
Because of its niche positioning and loyal user base, Obsidian benefits from strong subscription retention, though exact figures are not publicly available.
There is no publicly known valuation for Obsidian.
Since the company is bootstrapped and has not raised venture capital, it does not have a market-defined valuation.
Any valuation figures found online are hypothetical and typically derived using SaaS revenue multiples. These should not be treated as factual.
What is more important than valuation in Obsidian’s case is:
This gives the company long-term strategic flexibility.
Not natively.
Obsidian does not include built-in AI features in its core product.
However:
This means AI functionality exists within the ecosystem, but it is not controlled or provided directly by Obsidian.
Obsidian does not release official engagement metrics.
However, several indirect signals indicate strong product engagement:
These signals suggest:
Rather than optimizing for daily usage metrics, Obsidian appears to optimize for long-term knowledge accumulation and user ownership.
While exact numbers are not disclosed, Obsidian’s growth can be understood through ecosystem expansion and adoption trends.
It is important to clarify:
What is clearly visible is that growth is:
Obsidian’s pricing reflects its philosophy of being free at its core, with optional paid upgrades for convenience and support.
The full Obsidian app is completely free to use with no limits.
It includes local storage, plugins, themes, and full functionality without requiring any subscription.
Sync Standard
Sync Plus
This allows users to turn their notes into fully functional websites with built-in hosting, search, and customization.
This is not a feature unlock, but a way for users to support Obsidian’s development and get early access to insider builds and community perks.
Previously required for business use, the commercial license is now optional. Individuals and companies can use Obsidian for work for free, and the license acts as a way to support the company.
Obsidian is fundamentally different from most SaaS tools:
This model aligns with Obsidian’s broader philosophy of being user-first, privacy-focused, and independent.
Unlike traditional productivity tools, Obsidian is built around personal knowledge management (PKM). Its local-first Markdown system attracts users who want full ownership of their information while building interconnected knowledge systems.
Below are the most common real-world use cases across different user groups.
Developers use Obsidian as a personal technical knowledge base rather than a simple note-taking app. The ability to link ideas, code snippets, and documentation makes it ideal for long-term learning and problem solving.
Common developer workflows include:
Because notes are stored locally as Markdown files, developers appreciate the flexibility and long-term portability of their knowledge.
Students use Obsidian to transform traditional note-taking into a structured learning system. The bidirectional linking feature helps connect concepts across subjects, improving understanding and memory retention.
Typical student use cases:
Many students adopt Obsidian as a “second brain” to manage knowledge beyond exams.
Researchers rely on Obsidian to handle large volumes of information and citations. Instead of scattered documents, Obsidian enables a connected research environment.
Research workflows often include:
The local-first architecture is particularly valuable for researchers handling sensitive or proprietary information.
Writers and content creators use Obsidian to develop ideas over time rather than managing isolated documents. Linking notes helps writers discover patterns, themes, and story connections.
Common creator workflows:
This approach supports creative thinking by turning notes into an evolving knowledge network.
Obsidian has become a central tool within the PKM movement — users focused on building structured thinking systems and lifelong learning environments.
Popular PKM use cases include:
The philosophy behind Obsidian aligns with users who prioritize knowledge ownership, flexibility, and long-term thinking over cloud-dependent productivity platforms.
Obsidian represents a different kind of SaaS success story.
Its growth is built on:
User trust
Local-first architecture and privacy-first design
Community ecosystem
Plugins, themes, and shared workflows
Clear positioning
Focused on serious knowledge work rather than mass-market productivity
Instead of optimizing for rapid scale, Obsidian optimizes for depth and longevity.
This results in:
