Edbrowse is a combination editor, browser, and mail client that is 100% text based. The interface is similar to /bin/ed, though there are many more features, such as editing multiple files simultaneously, and rendering html. This program was originally written for blind users, but many sighted users have taken advantage of the unique scripting capabilities of this program, which can be found nowhere else. A batch job, or cron job, can access web pages on the internet, submit forms, and send email, with no human intervention whatsoever. edbrowse can also tap into databases through odbc. It was primarily written by Karl Dahlke.
The inspiration for this program came from Karl's many years of experience as a blind computer user.

LosslessCut aims to be the ultimate cross platform FFmpeg GUI for extremely fast and lossless operations on video, audio, subtitle and other related media files. The main feature is lossless trimming and cutting of video and audio files, which is great for saving space by rough-cutting your large video files taken from a video camera, GoPro, drone, etc. It lets you quickly extract the good parts from your videos and discard many gigabytes of data without doing a slow re-encode and thereby losing quality. Or you can add a music or subtitle track to your video without needing to encode. Everything is extremely fast because it does an almost direct data copy, fueled by the awesome FFmpeg which does all the grunt work.
Lossless cutting of most video and audio formats. Losslessly cut out parts of video/audio (for cutting away commercials etc.) Losslessly rearrange the order of video/audio segments. Lossless merge/concatenation of arbitrary files. Lossless stream editing.
In the AUR. Uses Electron.

SilverBullet is an extensible, open source personal knowledge management system. Indeed, that’s fancy talk for “a note-taking app with links.” However, SilverBullet goes a bit beyond just that. Runs in any modern browser (including on mobile) as a PWA in two modes (online and synced), where the synced mode enables 100% offline operation, keeping a copy of content in the browser, syncing back to the server when a network connection is available.

Optimized for keyboard-based operation. Plugins supported.

This is Ennuizel, an audio editor for web browsers! Ennuizel is based on libav.js, which is in turn based on FFmpeg.
Although Ennuizel is perfectly usable as an interactive audio editor, its design intent is to be used as middleware for platforms providing other web-based audio systems. For instance, Ennuicastr uses Ennuizel to provide automatic mastering.
