Spec score 8.7 #4 of 31 in Outliner Software

What it is

Indenta is a free outliner note app for structured notes with Markdown, backlinks, tags, and tasks. Notes are trees of nestable, collapsible lines that can be rearranged or explored by zooming into a branch. Wiki-links, automatic backlinks, saved searches, tags, and date-based search help organize notes. Any line can become a task, and a task view gathers open tasks across notes; the journal stores each day as a branch in one note. Notes stay 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 and import an Indenta ZIP or individual Markdown files. Optional sync can transfer notes directly between devices through end-to-end encrypted WebRTC, or use Google Drive. Indenta runs in a browser and can be installed with Chrome or Edge, or added to an iOS home screen through Safari. It has no paid tiers or stated feature or device limits.
