The AI Text Expander You Can Talk To
Repetitive typing slows you down. Lightning Assist lets you expand snippets, run AI commands, and dictate with your voice — inside any app on Windows, macOS & Linux.
One App. Three Superpowers.
The average knowledge worker retypes the same responses 15 times a day. Lightning Assist cuts that to zero — with a hotkey, a snippet, or your own voice.
Instant Text Expansion
Type a short keyword, press your hotkey, and watch it expand into full emails, code blocks, or templates. No more copy-pasting. Read our productivity blog for tips and tutorials.

How It Works — 4 Steps, Under 2 Minutes
No config files. No scripting. Just create, assign, type, and trigger.
- Step 1
Create a snippet
Write the text you want to reuse — an email reply, a code block, a support response — and give it a short keyword like ty1 or sig.
- Step 2
Pick a trigger hotkey
Choose which hotkey activates your snippet — one press is all it takes.
- Step 3
Type your keyword anywhere
In any app — your email client, browser, IDE, Slack, or even a terminal — just type the keyword.
- Step 4
Press the hotkey — done
Your keyword is instantly replaced with the full snippet. That's it. No popup, no menu, no delay.
Terminal Resources — same flow, works in your CLI
Create snippets that expand inside PowerShell, CMD, bash, or any terminal. Same idea: keyword + trigger. You get a separate hotkey for terminal so your app shortcuts and terminal shortcuts don’t clash. One tool for both.
Stop Typing the Same Things Over and Over
Text expansion, AI commands, and voice dictation — all in one app. See pricing or read the blog for tips.
