Slash That vs Espanso: which text expander fits you?
Espanso is a free, open-source text expander loved by developers. Slash That is a browser extension built for people who write to customers, patients and clients all day. Here's how they compare, and who each one is for.
- Choose Espanso if you're comfortable editing configuration files, want a free tool that works in every desktop app, and like scripting your own snippets.
- Choose Slash That if you want to be up and running in 30 seconds without touching a file, with a visual editor, AI rewriting, one-click translations, and templates your whole team can share.
Side by side
| Slash That | Espanso | |
|---|---|---|
| Price | Free for 10 templates. Lite $29 / year, Pro $59 / year. | Free and open source (GPL-3). Donations welcome. |
| How you create templates | A visual editor in your browser. No files, no syntax. | Text configuration files you edit by hand. A graphical editor is planned. |
| How you trigger text | Type / and a few letters. A menu shows matching templates with a preview. | Type a keyword like :sig, or press Alt+Space to search. |
| Where it works | Chrome, anywhere you type on the web. Edge, Firefox and Safari are coming. | Most desktop apps on Windows, macOS and Linux. |
| AI | Built into the editor: shorten, make warmer or more formal, fix grammar, translate. | Not built in. Possible through your own scripts. |
| Multiple languages | Each template holds its language versions. /noshow.fr inserts the French one. | A separate snippet for each language. |
| Sync between devices | Automatic. Your templates follow your account. | Do it yourself: move the config folder into Dropbox, Google Drive or Git. |
| Team sharing | Shared folders on the Enterprise plan. Update once, everyone gets it. | Share config files or packages yourself. |
| Power features | Fill-in fields like {{first_name}}. | Forms, dates, shell commands and scripts, community packages on the Espanso Hub. |
1. Setup: 30 seconds vs a config file
Espanso follows a Unix-style philosophy: your snippets live in text files that you edit and reload. That's powerful and transparent, and many developers love it. For a salesperson, a receptionist or a paralegal, it's a real barrier.
Slash That is a browser extension with a visual editor. Sign in, write a template, give it a shortcut and use it straight away. Nothing to install on your computer and no syntax to learn.
2. Finding the right message
Both tools let you avoid memorising everything. Espanso has a search bar on Alt+Space. In Slash That, the search is the trigger itself: type / and a few letters, and matching templates appear with a preview right where you're typing.
3. AI and translations
Slash That has AI built into the editor. Draft a message, then click Shorten, Warmer, More formal or Fix grammar, or add a French, German or Spanish version in one click. Espanso doesn't include AI rewriting; you could wire something up with scripts, but you'd be building it yourself.
4. Teams and syncing
Espanso is a personal tool at heart. To use your snippets on another computer, you move the configuration folder into a synced folder like Dropbox or a Git repository. Sharing with colleagues works the same way, by hand.
In Slash That, templates are saved to your account and follow you to any computer. On the Enterprise plan, teams share folders of templates, so when someone improves one, everyone has the new version.
5. Where Espanso is the better choice
We'd rather you pick the right tool. Espanso wins clearly when:
- You want it free. Espanso costs nothing and is open source.
- You work outside the browser. It expands text in most desktop apps on Windows, macOS and Linux. Slash That currently works in Chrome.
- You like to script. Shell commands, custom scripts, forms and community packages make it extremely flexible.
- You want everything local. Your snippets stay in files on your own machine.
The verdict
Espanso is a brilliant free tool for developers and tinkerers who are happy in configuration files. Slash That is built for everyone else: people who write to customers all day in Gmail, LinkedIn, their helpdesk or CRM, and want a visual editor, AI rewriting, translations and team sharing without any setup.
