A full LaTeX compiler with an inline code runner (20 languages), built-in symbolic math solver, chemistry rendering, AI assistance, and image-to-code conversion. Everything runs in your browser — no signup, no install, no Overleaf account.
▶
Run code inline New
Select any lstlisting block with [language=X] and click ▶ Run. Output (stdout or stderr) is captured and inserted as a green or red-bordered LaTeX box, right after the code. 20 languages supported — Java, Python, C, C++, C#, Go, Rust, JavaScript, Ruby, PHP, Bash, and more. Multi-file projects work: adjacent blocks with name= group automatically. Same engine as the dedicated /online-X-compiler tools.
Σ
Math solver
Select any \int, \frac{d}{dx}, \lim, or matrix operation (\det A, A^{-1}, eigenvalues, …) and hit Σ Solve. The answer and a full step-by-step derivation are inserted as LaTeX into a fresh solution-001.tex. Powered by nerdamer + SymPy for partial fractions, trig substitutions, L'Hôpital, cofactor expansion, and more — optional pgfplots graph or geometric viz included.
⚛
Chemistry rendering
Select any \ce{H2O} or \ce{2H2 + O2 -> 2H2O} and choose Lewis dot, SMILES 2D, or 3D geometry. The structure renders as an image with a property table (geometry, polarity, mol. weight, hybridization, etc.) inserted as a ready figure.
✨
AI assistant
Describe LaTeX in plain English and get code (Ctrl+Shift+A). When compilation fails, click AI Fix on the error to repair it automatically. Rewrite selections as formal academic, concise, or expanded tone.
📷
Image to LaTeX
Drag a screenshot of a math equation, table, or matrix into the editor — vision AI converts it into LaTeX source you can edit. Works for handwritten equations, textbook scans, and whiteboard photos.
⚡
Real-time PDF preview
Full TeX Live distribution on the server — every package you need (mhchem, tikz, hyperref, booktabs, listings, … thousands more). Compile with Ctrl+Enter, preview as native PDF or page-by-page canvas.
⌨
Smart editor
170+ autocomplete commands, syntax highlighting, bracket matching, symbol picker (Greek, math, arrows), multi-file projects with \input{}, voice-to-LaTeX dictation, and inline error markers.
💾
Auto-save, no signup
Projects auto-save to browser localStorage. Switch between multiple documents, rename, export .tex or PDF. No account, no email, no tracking — your work never leaves your browser unless you compile.
Try it now: pick Run Code for a multi-language tour with single-file and multi-file examples, Calculus or Linear Algebra for Σ Solve, or Chemistry for Lewis / 2D / 3D rendering.
