Formula snippets: write an equation once, use it everywhere

Some equations follow you around. The loss function you put in every paper. The Navier–Stokes momentum equation you write on every slide deck. The Bayes rule you paste into every student handout. Each time, you go looking for the last file you used it in.

Formula snippets keep them in one place.

What a snippet is

A snippet is a single piece of LaTeX, usually an equation, saved on its own with a live rendered preview. You can:

• Copy the LaTeX straight into any project
• Share it by link with a co-author or student
• Download it as an image, PNG or JPEG, at the resolution you choose

Try one without an account

Go to the Luzbase homepage, type an equation into the snippet box and click Create snippet. That's it. No sign-up.

Because there's no account to tie it to, Luzbase gives you a secret key for a guest snippet. Save it: it's how you prove the snippet is yours. If you sign up later, use Claim ownership and the snippet moves into your account.

One thing to know: snippets created without an account are public, and anyone with the link and secret key can view, edit or delete them. That's fine for a quick share. For anything you want to keep, sign in.

Images for slides and documents

Getting a clean equation into PowerPoint, Keynote or Google Slides is still oddly hard. The image download handles it:

• PNG or JPEG
• Text colour and background colour, so it matches a dark slide theme
• Transparent background for PNG, so it sits on any slide
• DPI, so it stays sharp on a projector

Write the equation in LaTeX once, export it at 300 DPI, and it looks the same on the slide as in the paper.

Explore public snippets

Explore lists public snippets from other Luzbase users. It's a good place to find a correctly typeset version of a standard result instead of writing it from memory. Mark the ones you use as Favourites and they show up next to My snippets.

Private snippets

On Pro, snippets can be private, visible only to you. You can still share one with a private link and reset that link at any time if it travels further than you meant. That's useful for unpublished results you want to send to one collaborator.

A small habit that adds up

Next time you write an equation you've written before, make it a snippet. After a month you'll have a personal library of your field's notation, typeset the way you like it.
