Indenta

Indenta is a free outliner note app for creating structured notes with Markdown, tasks, links, and tags. Notes are built as nested, collapsible lines that can be rearranged or viewed by zooming into a branch. Wiki-links, automatic backlinks, tags, saved searches, and date-based search help organize and find material. Any line can be turned into a task, and a task view gathers open tasks across notes. A journal can keep each day as a branch in one note.

Notes are saved in the browser's IndexedDB on the user's device, and the installed Progressive Web App works offline. Users can export notes as Markdown files in a ZIP, or import an Indenta ZIP or individual Markdown files. Optional syncing is available directly between devices over end-to-end encrypted WebRTC, or through Google Drive. Indenta runs in a browser and supports web, Windows, macOS, Linux, Android, and iOS. It has a free plan with no stated feature or device limits and no paid tiers. The maker says it does not run analytics or track app use, though third-party ads may appear on the site and in some parts of the app.

Indenta combines an outline-based note structure with tasks, journaling, search, and optional sync. Its device-based storage makes keeping exports or a Google Drive backup important for recovery.

Indenta suits people who want to organize notes as nested outlines and connect them with links, tags, and searches. It may also fit users who need offline access, task lists, or a daily journal structure.

Indenta is a browser-based outliner for people who want notes, tasks, and a daily journal in one structured workspace. It is best suited to solo users who value offline access and are comfortable taking responsibility for their own backups. The trade-off is that losing access to a device can mean losing its notes unless they have been exported or synced.

Overview

Indenta makes each note a tree of nestable lines. You can collapse branches to see the shape of an idea, zoom into one section, or rearrange lines as it develops. Markdown, wiki-links, automatic backlinks, and tags support connected notes, while saved searches and date-based search help bring older material back into view. That combination favors people who organize by outlining and linking rather than by keeping a collection of flat documents.

Tasks and journaling follow the same structure. Any line can become a task, and a dedicated view collects open tasks from across notes, keeping actions near their context. The journal stores each day as a branch in one note. These are useful extensions for personal work, though Indenta's appeal rests on bringing them into an outliner rather than offering separate, specialized task or journal systems.

Key features

Offline work and data custody

Notes are stored in the browser's IndexedDB on the device, and the installed Progressive Web App works fully offline. That makes Indenta a practical option for working without a connection, but device-local storage also puts recovery in the user's hands: the developer cannot see, restore, or reset notes. Markdown exports in a ZIP and imports of Indenta ZIPs or individual Markdown files provide a portable backup route, but they require a habit of exporting.

Sync and privacy

Optional peer-to-peer sync transfers notes directly between devices through an end-to-end encrypted WebRTC connection. Google Drive sync is another option, placing notes in the account's hidden appDataFolder, which Indenta says only it can access. Both offer ways to keep notes beyond one device, but the Drive option depends on a Google account and neither changes the importance of maintaining a recoverable copy.

Indenta says it does not run analytics or track app use. Its site and, in some places, the app may show third-party ads, so the no-tracking claim should not be confused with an entirely ad-free experience.

On-device AI

The AI feature uses Chrome's Prompt API and requires desktop Chrome with its built-in model available. It is therefore a narrow extra, not a reason to choose Indenta if you primarily use another browser or a phone.

Pricing

Indenta's Free plan costs nothing. There are no paid tiers, feature gates, device limits, or trial clock, so its outlining, organization, offline use, and sync options are not split across plans. That makes it suitable for personal users who want to use the same app across supported platforms without a subscription. The main cost is not a plan cap but the responsibility to export or arrange backup for device-stored notes.

Platforms

Indenta runs in a browser and supports web, Windows, macOS, Linux, Android, and iOS. The guide describes installing it through Chrome or Edge, and adding it to an iOS home screen through Safari. That broad reach suits users moving between desktop and mobile, although the desktop-Chrome requirement for the AI feature makes that capability less portable than the core app.

Who it's for

Choose Indenta if you think in nested outlines, want notes linked to tasks and daily entries, and value an offline-capable workspace without a paid tier. It is a weaker fit for anyone who expects a vendor to recover lost data, wants an app that does not show third-party ads in some places, or needs the AI feature outside desktop Chrome.

Pros and cons

• Pros: Nested, collapsible notes can be zoomed into and rearranged, helping users keep detail and overview in one structure.
• Pros: Tasks, journal branches, backlinks, tags, and saved searches connect planning and retrieval to the same notes.
• Pros: The Free plan has no stated feature or device limits, and the installed app works offline.
• Cons: Device-based storage leaves recovery to the user; forgetting to export or set up sync can make a lost device costly.
• Cons: AI requires desktop Chrome with its built-in model, limiting its usefulness for users on other browsers or mobile.
• Cons: Third-party ads may appear on the site and in some parts of the app.

Verdict

Indenta is a strong choice for solo users who want a free, offline-capable outliner that keeps linked notes, tasks, and journaling together. Its device-local storage is the defining compromise: choose it if you will maintain exports or sync, and look elsewhere if you need someone else to recover your notes.
