In plain words
Edna is a browser-based note-taking app designed for developers and power users. It supports markdown, plain text, and code with a minimalist interface that prioritizes writing space. Notes can be stored locally in the browser or on disk, and optionally encrypted with passwords. The app combines features from Obsidian and Notational Velocity, requiring no installation while keeping data private and secure.

In the maker’s words, at launch
I took a small break from coding SumatraPDF and wrote a note taking application that is perfect for me: https://edna.arslexis.io/ Edna is a note taking app for developers and power users. A cross between Obsidian and Notational Velocity. Markdown, plain text, code, works in browser so no installation required, private (notes are stored in your browser or disk) and secure (can encrypt notes with a password). The story so far. I was always attracted to editors with minimalistic UI, like https://mak.ink/, simplenote, Notational Velocity. I like having most of the screen estate for writing because writing and editing is what note taking apps are for. But: most of them are very thin on features and UI. I saw Heynote and it was one of those minimalistic writing UIs with not many features. I liked their concept of dividing notes into blocks so I forked Heynote and started coding. The goal was to combine writing-oriented, minimalistic main UI while also providing on-demand UI for features and efficient operation. Things like context menu, type-down note switcher, command palette, quick access shortcuts, plenty of keyboard shortcuts. Another goal was privacy and security. The notes never leave your computer and can be encrypted with a password. It also makes the code simpler because I don't need any backend storage, user accounts and auth etc. Sadly, only Chrome and Edge provide the necessary file system api, on other browser you can only store notes in local storage, which means no sharing between computers or accessing the notes with other software. 40 working days and 528 commits later, here's what I've added: * added support for multiple notes * ability to store notes on disk * and if you store notes in a directory managed by DropBox, OneDrive etc., you get sharing of notes between computers * Ctrl + P: UI for switching between notes, creating new notes, deleting notes, inspired by Notational Velocity * Ctrl + Shift + P: command palette like in vs code * context menu to access frequently used functionality * Ctrl + E to open note from history (list of recently opened notes) * ability to assign Alt + 0 ... Alt + 9 quick access shortcuts * ability to encrypt notes with a password * export all notes to a .zip file * automatic, daily backup of notes to a .zip file (optiona, see Settings) * Ctrl + B to navigate between blocks * re-designed Settings UI * added ability to execute Go blocks * support Svelte and Vue in code blocks * ported the UI code from Vue to Svelte 5, just because I could * converted from desktop app to run in the browser (Ctrl is on Windows, on Mac it's ⌘). I've been using it daily while working on it. 94 notes and counting. I still have ideas for improvements but it has all the core features for productive work.

Many years ago, I made VJ softwares (to mix live visuals in clubs) for unexpected platforms like the Game Boy Advance, the Playstation 2 and the Raspberry Pi. This year, I’m back with a new web-app: Pikimov. Inspired by Photopea (a free Photoshop clone), I created this web-based motion design & video editor as an alternative to After Effects, to fill empty void. It's free, without signup, without cloud uploads (your files stay on your machine), and your projects are not used for AI models training.
