Free tools
LaTeX tools that run in your browser
Free, no sign-up, no upload of your work. The validator, equation preview, and table generator run entirely in your browser; lab search and deadlines query open datasets (OpenAlex, ccf-deadlines). Your source never leaves the page, the same local-first posture the Oleafly desktop app takes with your documents.
Lab search
Search millions of research institutions worldwide with publication counts and official links, powered by the open OpenAlex dataset.
BibTeX validator
Paste a .bib file and catch missing required fields, duplicate keys, and duplicate DOIs before they become [?] in your PDF.
Live LaTeX playground
Type LaTeX and watch it render as you type: mixed prose and math, align, matrices, cases. Loads any example from the Learn course.
Equation preview
Type LaTeX math and see it rendered instantly. Switch between inline and display mode and copy ready-to-paste code.
Table generator
Fill a visual grid and get clean tabular code out, with booktabs rules, per-column alignment, and a caption.
Conference deadlines
Live countdowns to CS conference submission deadlines, with CCF and CORE ranks, from the open ccf-deadlines dataset.
In the desktop app
Heavier conversions live in the free app
Some conversions need a real compiler or your own AI key, so they run in the free, open-source desktop app instead of the browser. Your projects stay as plain files on your disk there too.

Reconstruct many text-based PDFs into editable LaTeX projects locally, figures extracted, no AI required. Built into the free desktop app.
Word to LaTeX
Import a .docx through a managed Pandoc and get a compiling LaTeX project with images preserved. Built into the free desktop app.
Image to LaTeX
Photograph an equation or table and insert it as LaTeX using your own AI key. Built into the free desktop app.
