How do I convert a picture of an equation to LaTeX?

Upload the photo to the free LetX Equation to LaTeX converter at eq2latex.letx.app. It runs OCR and returns LaTeX code with a live KaTeX preview so you can verify the output matches before copying.

What is the easiest way to make a LaTeX table?

Paste your data as CSV into the free LetX Table Generator — it outputs a booktabs-formatted tabular environment you copy straight into your document. No hand-typing & separators or \\ line breaks.

How do I get BibTeX from a DOI?

Paste the DOI into the free LetX Citation Generator. It fetches the metadata and exports a BibTeX entry ready for your .bib file, alongside formatted APA, MLA, or IEEE citations.

Will paraphrasing tools break my LaTeX code?

Generic ones often do — they rewrite \cite{}, \ref{}, and math as if they were prose. Use a LaTeX-safe paraphraser like the LetX Paraphrasing Tool, which locks LaTeX commands and equations before rewriting.

5 Free LaTeX Tools That Save Hours of Typing

The most tedious LaTeX work — transcribing equations, typing &-separated table rows, hand-writing BibTeX — is exactly what these five free tools eliminate. Each one outputs copy-ready LaTeX, and each has an "Open in LetX" button that drops the result into a compiling project.

1. Equation to LaTeX — stop transcribing math

Snap a photo of handwritten or printed math and the Equation to LaTeX converter returns the code with a live KaTeX preview to verify against the original. You can also type plain English — "integral of x squared from 0 to 1" — and get:

\int_0^1 x^2 \, dx = \frac{1}{3}

Pairs well with the math symbols reference when you only need one symbol, not a whole expression.

2. LaTeX Table Generator — CSV in, booktabs out

Paste a CSV into the Table Generator and get a clean booktabs table — the academic standard — without hand-typing separators:

\begin{tabular}{lcc}
  \toprule
  Method & Accuracy & F1 \\
  \midrule
  Baseline & 81.2 & 0.79 \\
  Ours     & 89.6 & 0.88 \\
  \bottomrule
\end{tabular}

The tables guide covers captions, labels, and multi-column cells when you need more.

3. Citation Generator — DOI to BibTeX in seconds

Paste a DOI, ISBN, or URL into the Citation Generator and the metadata auto-fills — export as APA, MLA, IEEE, or a BibTeX entry for your .bib file. No more typos in author names breaking \cite{}. See BibTeX vs BibLaTeX for which bibliography system to use.

4. Markdown to LaTeX — draft fast, publish properly

Draft in Markdown, then run it through the Markdown to LaTeX converter — headings, lists, and emphasis map to LaTeX commands, and math is protected so $...$ survives intact. No Pandoc install needed; the full guide covers the Pandoc route too.

5. LaTeX-safe paraphrasing — edit prose, not commands

Generic rewriting tools mangle \cite{}, \ref{}, and equations. The LetX Paraphrasing Tool preserves LaTeX commands while rewriting the surrounding prose in five modes — your document still compiles afterward.

All 20 free tools — these five plus summarizers, calculators, PDF utilities, and more — live at letx.app/tools.
