Obsidian Review 2026: Is This Local-First Knowledge App Right for You?

Obsidian released version 1.13 for desktop and mobile on July 30, 2026. The release is not a dramatic AI rebrand or a move away from local Markdown. It improves several everyday parts of the workspace: finding settings, working with images, capturing content on iOS, navigating Bases, managing Sync files, and recognising actions that cross a security boundary. That combination matters more than a flashy isolated feature because it reduces friction around the repeated actions that determine whether a knowledge system remains usable.

The desktop Settings panel has been rebuilt with search, keyboard navigation, and a new settings API for plugin developers. Core settings and core-plugin settings can now be found by name or description. Community-plugin settings appear in search only after their developers migrate to the new API, so buyers should not assume every installed setting is immediately searchable. Settings can open in a separate window, navigation works with arrow keys and Enter, and users can return focus to search with Ctrl-F or Cmd-F. Obsidian also lets users exit Restricted Mode without automatically re-enabling plugins, which is useful when troubleshooting a vault or testing whether a plugin caused a problem.

Image handling received a more visible upgrade. Images can open in a full-screen viewer, users can move between images embedded in the current note, and Live Preview provides direct keyboard selection, deletion, copy, cut, resize, reset, and edit controls. These changes should make image-heavy research, design references, field notes, recipes, and documentation easier to inspect. They do not turn Obsidian into a full image editor or digital-asset manager. File locations, rights, captions, alternative text, compression, backup, and Publish behaviour still require a deliberate workflow.

The mobile release adds an iOS Share Sheet that can save content from Safari, YouTube, social apps, and other sources without first opening Obsidian. Users can define several Locations, with each Location pointing to a vault, folder, and template. This is a meaningful capture improvement because it reduces the distance between finding something and placing it into the correct research or project structure. It can also increase inbox debt. A strong setup should use a small number of destinations, preserve the original source, capture only necessary material, and schedule review rather than sending every interesting item into permanent storage.

Mobile 1.13 also adds tab reordering, tablet split resizing, a column-resize menu for Bases tables, and improved handling of long documents and text selection. The release raises the minimum iOS version to iOS 15. Anyone managing older devices should check operating-system support before treating the new Share Sheet as a universal team feature. Plugin behaviour can also remain different across desktop and mobile, so a workflow should be tested on the actual devices used in production.

Several security changes deserve more attention than their release-note size suggests. Obsidian URI actions now show a confirmation dialog before firing, and trusted actions can be placed on an allow list. The app warns before loading HTML resources from a network drive, warns when users choose to synchronise plugins, and uses clearer language when an unrecognised vault contains plugins. These prompts reflect the real Obsidian security model: a vault can be local and still contain third-party code, embedded network content, executable URI actions, or configurations that spread to other devices.

The correct response is not to approve every prompt once and forget it. Review which URI actions are allowed, keep Restricted Mode enabled for untrusted vaults, test community plugins in a copy, and synchronise plugins only when their code and update path are acceptable on every connected device. Sensitive organisations should maintain an approved plugin list, version and change controls, dedicated model-provider rules, incident ownership, offboarding steps, and independent backups.

Sync usability also improved. The Sync sidebar can now search files, select several records with keyboard or mouse controls, drag files into other views, and delete through the keyboard. This can make version investigation and recovery faster, but convenient deletion increases the need to understand retention. Obsidian's privacy summary says remote Sync or Publish data remains for one month after a subscription expires, then is deleted, while manually cancelling deletes remote service data immediately. Local vaults remain unaffected. Buyers should test restoration and keep an independent backup before cancelling or changing a shared workspace.

Obsidian published smaller Catalyst builds on August 5 and August 7 after the public 1.13 release. Those early-access builds include incremental fixes and a Bases column-resize command, but Catalyst status means they should not be described as the stable public baseline. Teams should use the July 30 public release for procurement and documentation unless they have consciously chosen beta testing, defined rollback, and checked plugin compatibility.

The AI distinction remains unchanged. Obsidian 1.13 does not add a bundled chat assistant, model allowance, or general agent. The official Web Clipper Interpreter can call a model chosen by the user, including local options, and community plugins can add broader AI experiences. In both cases the model, context, costs, retention, training terms, output quality, and security boundary depend on the selected provider and plugin. That flexibility is valuable, but it transfers more evaluation responsibility to the user.

WhatAI's take: version 1.13 strengthens Obsidian's position as a durable, user-controlled knowledge workspace. Searchable settings reduce configuration friction, image tools improve real editing, iOS capture closes a mobile gap, and the new warnings make plugin and URI risk harder to ignore. The best evaluation is still outcome-based. Build one small vault, capture real work for thirty days, retrieve information under time pressure, restore a deleted note, test a second device, and measure plugin maintenance. Obsidian wins when its local files and customisation make thinking easier without turning the workspace itself into the project.

WhatAI Decision Box

Obsidian is a free local-first workspace built around Markdown files, links, properties, Bases, Canvas, plugins, and offline access. It can become a personal knowledge base, research system, writing environment, project tracker, documentation hub, or digital garden while keeping the primary vault on the user's device.

The core app is free for personal and commercial use, and the old mandatory work licence was removed in February 2025. Optional purchases include Sync from $4 per user monthly on annual billing, Publish from $8 per site monthly, a $25 one-time Catalyst licence, and an optional $50 annual Commercial supporter licence.

Obsidian does not bundle a general-purpose AI assistant or model allowance into the core app. The official Web Clipper Interpreter can call a user-chosen local or external model, while most vault chat, semantic search, drafting, and automation features come from third-party community plugins. Review every plugin and provider before giving it sensitive notes or an API key.

Obsidian Pros & Cons

How to Get Results with Obsidian: Step-by-Step Workflow

1. Define the knowledge outcome

   Choose one outcome such as research recall, project documentation, writing, study notes, meeting follow-up, or a personal CRM. Define what must be easier after thirty days.

2. Create a minimal local vault

   Choose a controlled device location, confirm file permissions and storage ownership, and begin with only a small inbox, projects area, references area, and archive.

3. Design portable note conventions

   Set simple rules for filenames, links, headings, properties, source URLs, dates, attachments, and status. Prefer readable Markdown before adding plugin-specific syntax.

4. Build capture templates

   Create daily-note, meeting, source, project, and decision templates. Configure Web Clipper templates to capture only the content and metadata required for the chosen workflow.

5. Connect notes deliberately

   Link a note only when the relationship will help future retrieval or thinking. Use backlinks, properties, tags, and Maps of Content for different jobs rather than duplicating one hierarchy everywhere.

6. Add one Base or Canvas

   Use a Base when structured properties need filtering or calculation. Use Canvas when spatial arrangement helps explain a problem. Verify that every view still points to understandable source files.

7. Secure sync and backups

   Decide whether Sync or another approved method is needed, enable secure account recovery, test version restoration, and maintain a separate scheduled backup that is not merely another live mirror.

8. Review plugins and AI

   Add only plugins that solve measured requirements. Check source, permissions, network use, maintenance, provider terms, API-key storage, data sent, model cost, failure behaviour, and an uninstall path.

9. Pilot across real devices

   Test capture, editing, search, links, Bases, attachments, conflicts, offline work, mobile use, restore, export, and plugin consistency with representative notes before expanding the vault or team.

10. Measure retrieval and maintenance

    After thirty days, measure whether information is found faster, decisions are clearer, writing is easier, and repeated work is reduced. Remove structures and plugins that create more maintenance than value.

Obsidian Gotchas and Limits to Know Before You Start

• Obsidian's core app is free for commercial use; a Commercial licence is optional support, not a work-use requirement.
• The $50 Commercial licence and $25 Catalyst licence do not include Sync or Publish.
• Sync and Publish prices are separate, and team cost scales by Sync users and Publish sites.
• Sync Standard limits one vault to 1 GB total storage, 5 MB per file, and one month of history.
• Sync Plus limits ten vaults to 10 GB total storage, 200 MB per file, and twelve months of history before any storage upgrade.
• The seven-day refund applies to Sync and Publish, while Catalyst, Commercial, and Obsidian Credit are non-refundable.
• Cancelling Sync or Publish can delete remote service data immediately, although local vaults remain unaffected.
• End-to-end encrypted Sync does not replace device encryption, account security, safe recovery, access control, or independent backups.
• A mirrored sync folder is not automatically a backup because deletion, corruption, and mistakes can propagate.
• Shared vault collaboration is not the same as live cursor-based co-editing and can still produce file conflicts.
• Community plugins are third-party code and are outside the official core software covered by Obsidian's terms.
• Plugins may access or modify vault files and may connect to external services, so directory listing is not a complete security guarantee.
• Synchronising plugins can spread one risky or broken configuration across devices.
• Most AI chat, semantic search, drafting, and agent workflows in Obsidian come from community plugins, not a native Obsidian model service.
• Web Clipper Interpreter sends the chosen page context and prompts directly to the selected model provider unless a local model is used.
• External AI providers can charge separately and apply their own retention, training, residency, and acceptable-use terms.
• AI summaries, extracted metadata, links, tags, and answers can be incomplete or wrong and require source review.
• Markdown portability does not preserve every plugin query, theme, Canvas layout, Base view, embed, or wikilink behaviour in another app.
• Bases creates views over files and properties, not a hosted relational database with transactions and enterprise permissions.
• Large vaults, heavy plugins, complex queries, many embeds, or low-powered mobile devices can affect performance.
• The official CLI requires the Obsidian 1.12.7 or later installer and normally controls a running app.
• Publish makes selected content available through a hosted service, and password protection does not replace a formal confidential-document system.
• Publish users are responsible for source rights, privacy notices, analytics configuration, accessibility review, and lawful public content.
• The mobile experience and plugin support can differ from desktop, especially for complex community workflows.
• Folder structure, properties, tags, links, plugins, and templates can become a maintenance project if they are designed before a real retrieval need exists.
• No public official Obsidian affiliate programme was verified as of August 9, 2026.

Which Obsidian Feature Fits Your Use Case

Starter Prompts for Obsidian

What is Obsidian?

Obsidian is a local-first note-taking and knowledge-management application. It stores most note content as Markdown files in a vault folder on the user's device, then adds links, backlinks, properties, search, graph views, Bases, Canvas, plugins, themes, Sync, and publishing tools.

Is Obsidian free?

Yes. The core desktop and mobile apps are free without a time limit or account requirement. Obsidian states that free use covers personal, commercial, nonprofit, education, and government purposes. Sync, Publish, Catalyst, and Commercial support are optional purchases.

Do businesses need an Obsidian Commercial licence?

No. Obsidian made the Commercial licence optional on February 20, 2025. Work and commercial use are now free. The $50 per-user annual Commercial licence supports development and may provide supporter recognition, but it is not required to use the app for business.

How much does Obsidian Sync cost?

Sync Standard costs $4 per user per month on annual billing or $5 monthly. Sync Plus costs $8 per user per month annually or $10 monthly. Standard includes one synced vault, 1 GB storage, a 5 MB file limit, and one month of history. Plus includes ten vaults, 10 GB, a 200 MB file limit, and twelve months of history.

How much does Obsidian Publish cost?

Publish costs $8 per site per month when billed annually or $10 on monthly billing. The public page includes up to 4 GB of hosting, custom domains and themes, search, graph navigation, backlinks, password protection, metadata controls, and priority support.

Does Obsidian have built-in AI?

The core note application does not include a general AI chat assistant or bundled model credits. The official Web Clipper has an optional Interpreter that connects to a model selected and funded by the user. Most other Obsidian AI experiences are community plugins, not native Obsidian services.

Can Obsidian use ChatGPT, Claude, Gemini, or local models?

Yes, through the Web Clipper Interpreter or community plugins that support those providers. The user normally supplies an API key or local runtime. Model fees, retention, training terms, data location, context sent, and output accuracy depend on the selected provider and plugin.

What are Obsidian Bases?

Bases is a core plugin for database-like views of notes and properties. It supports table, list, card, and map views plus filtering, sorting, grouping, and formulas. The source data remains in local Markdown and YAML properties, while each view is stored in a .base file or embedded block.

Is Obsidian private?

The core app stores vault data locally and Obsidian says it collects no telemetry from desktop or mobile apps. Privacy changes when users activate Sync, Publish, embedded websites, community plugins, browser capture, external storage, or AI providers. Each connection should be reviewed separately.

Is Obsidian Sync end-to-end encrypted?

Yes. Obsidian says Sync uses AES-256 end-to-end encryption, including file names, and the service has undergone independent security audits. This protects the remote Sync service, but users still need secure devices, accounts, recovery practices, access controls, and independent backups.

Are Obsidian community plugins safe?

They are third-party code, not part of the core Obsidian software. Directory policies and review processes reduce risk but do not eliminate it. A plugin may read or change vault files and may use the network. Keep Restricted Mode on for sensitive vaults unless each plugin, permission, update path, and provider is acceptable.

Can teams collaborate in Obsidian?

Yes, through shared Obsidian Sync vaults and collaborative Publish workflows. The experience is based on synchronised files and is not identical to simultaneous cursor-based editing in Google Docs or Notion. Test conflicts, permissions, deletion, ownership, offboarding, and plugin consistency before a team rollout.

Does Obsidian work offline?

Yes. Local vaults can be created, searched, linked, and edited offline. Sync catches up after the device reconnects. Features that require a provider, including Publish, external AI calls, plugin downloads, embedded websites, and some community-plugin services, still need network access.

Does Obsidian have an API?

Obsidian provides a developer API for plugins, an official CLI, Obsidian URI actions, and local files that other programs can process. It is not a conventional hosted notes REST API. The CLI usually controls a running app, and plugin or script access must be secured like any local automation.

Can I move my Obsidian notes elsewhere?

Most note content is portable Markdown stored in ordinary folders. Standard text, headings, links, and files are easier to migrate than a cloud-only database. Plugin-specific syntax, wikilink behaviour, properties, Canvas files, Bases views, themes, queries, and automation may need conversion in another application.

Does Obsidian have an affiliate program?

No. In the official community forum, an Obsidian team representative said on May 30, 2026 that the company was not interested in pursuing a referral or affiliate programme. Use a direct non-affiliate link unless Obsidian later publishes current application and commission terms.

What are the best Obsidian alternatives?

Notion offers easier hosted collaboration and built-in workspace AI, Capacities focuses on object-based knowledge, Logseq offers an open-source local-first outliner, and Evernote emphasises capture and conventional notebooks. Compare file ownership, offline depth, collaboration, AI governance, plugins, mobile experience, migration, and total maintenance time.
