Audacity is a free, open-source, cross-platform audio editor. It's a multi-track recorder and waveform editor that handles everything from capturing a single voice memo to cleaning up podcast episodes, digitising old recordings, and assembling layered audio. It works on uncompressed audio for editing and exports to MP3, WAV, FLAC, OGG, and more. This guide covers macOS Tahoe (Apple Silicon), Fedora 43 KDE, and Windows 11.

Darktable is a free, open-source RAW photo processor and digital darkroom — a full alternative to Adobe Lightroom. It works non-destructively: your original files are never modified, and every edit is stored as a set of instructions in a sidecar file or its internal database. It supports a huge range of RAW formats and runs on macOS, Linux, and Windows.

GIMP (GNU Image Manipulation Program) is a free, open-source raster image editor — a capable alternative to Adobe Photoshop. It handles photo retouching, digital painting, graphic design, and image compositing. It's one of the most mature open-source applications available, with a large plugin ecosystem and scripting support (Python-Fu and Script-Fu).

KDenLive (KDE Non-Linear Video Editor) is a free, open-source video editor that supports multi-track editing, a wide range of formats (including ProRes, H.264, HEVC, and more), a GPU-accelerated preview, and a comprehensive effects library. It's a capable alternative to DaVinci Resolve for most editing tasks, and it's particularly well-integrated on KDE Plasma.

Notion is an all-in-one workspace that combines notes, databases, kanban boards, wikis, and calendars in a single app. It can replace a collection of separate apps — or become a chaotic mess if you don't have a clear structure from the start. This guide walks through installation, core concepts, and practical workflows.

Obsidian is a local-first Markdown note-taking app built around the idea of linked notes. Unlike Notion, all your data lives as plain .md files in a folder on your computer — no account required for basic use, no internet dependency, and no vendor lock-in. It's fast, highly extensible through plugins, and particularly well-suited to building a personal knowledge base or "second brain".
