Raycast replaces Spotlight and a dozen other utilities behind a single CMD+Space hotkey — app launcher, clipboard manager, window manager, snippets, calculator, and more. All free.
Fuzzy search with frecency ranking. Type a few letters, hit Enter — faster than Spotlight, and it learns your habits.

One of the best built-in features. By default, macOS only holds one thing in your clipboard — with Raycast you get a seemingly unending history that even survives a restart. Text, images, colors, links — all searchable. If a screenshot or image contains text, you can search for that text too. Pin the most used items and reuse whenever you want. It may sound silly, but I use clipboard history multiple times a day.

Snap windows to halves, thirds, quarters with custom hotkeys. I often work with two windows side by side — one left, one right. My shortcuts: Ctrl+Opt+← for left half, Ctrl+Opt+→ for right half, Ctrl+Opt+↑ for full screen. Replaces Rectangle, Magnet, and similar apps.

Text expansion with keywords. Type a short keyword, and it expands to a full text block. Supports dynamic placeholders like {cursor} to position your cursor after expansion — e.g. console.log({cursor}) places you right between the parentheses. Some of mine:
\mail → nurs.asanov@pm.me\li → https://www.linkedin.com/in/nursultan-asanov/\raddr → 3rd Floor, 1 Ashley Road, Altrincham, Cheshire, United Kingdom, WA14 2DTclg → console.log()Inline math and unit conversions right in the launcher. Press Enter to copy the result to clipboard.

Instant file search with inline preview. Faster than Finder search and shows file contents without opening them.
Quick notes that float on top of all windows. Supports markdown, checklists, and character counts. Free plan limits you to 5 notes — enough for me, bigger and detailed notes go in Notion.

Custom URL shortcuts with parameters. Type "gh {query}" to jump straight to a GitHub repo, or "jira {ticket}" to open a Jira issue. Some of mine:
g → Google searchhdr → HDRezka searchyou → YouTube search
If you find yourself doing the same actions repeatedly, scripting in Raycast can help automate them, reducing friction and saving time. Navigate to Extensions > Create Script Command, write a simple script in Bash, Python, or Node.js, and assign a keyword or shortcut to trigger it instantly. Step-by-step guide

Search within your screenshots by text content — Raycast OCRs them so you can find any screenshot by what's written on it. Not a full system search, it's a dedicated command you invoke from the launcher.
Free extensions from the Raycast Store I use daily.
Raycast has a great YouTube channel where Pedro shares tips and ways to get the most out of the app.
Even if you never touch extensions, snippets, or window management — just using Raycast as a launcher, calculator, and clipboard history alone is already a massive upgrade over the default macOS experience.
