About Semi
FREE TO START
Save up to 20 snippets for free, no account, no time limit.
UPGRADE ONCE, NOT EVERY MONTH
Other text expanders charge $3-8 every month, forever. If you outgrow the free plan, Semi's upgrade is a one-time purchase for unlimited snippets. Pay once, use it as long as you want.
EVERYTHING RUNS IN YOUR BROWSER
No account required, no cloud sync required, no data sent anywhere. Your snippets are stored locally (with optional Chrome sync across your own devices, built into Chrome itself, not a server we run).
HOW IT WORKS
1. Click the Semi icon and add a snippet: a shortcut (like addr) and the text it should expand to.
2. Anywhere you type, type ; followed by your shortcut, then hit space, tab, or enter.
3. Your shortcut is replaced with the full text automatically.
WHERE IT WORKS
Semi works in standard text fields across the web, including Gmail, Notion, Slack, X, and most forms and text boxes. Some highly custom editors (like Google Docs) aren't supported.
