ChemAI — LaTeX Chemistry Editor
Type LaTeX (use \ce{...} for formulas) to render chemical equations. Export to PNG/PDF, copy LaTeX, and use templates/autocomplete.
Designed for chemists, educators, and students, the editor supports mhchem, MathJax, and plain-text output so you can publish balanced reactions anywhere.
Your LaTeX input autosaves locally in this browser so you can pick up where you left off.
Mode:
Start typing
\ce{ and press Ctrl+Space to open autocomplete.Rendered output will appear here.
Worked Examples & Templates
Use these LaTeX snippets with \ce{} (mhchem) for fast, accurate chemical typesetting. Follow the steps to render and export.
1) Balance and typeset a combustion reaction (Ethanol)
- Insert into the editor:
\ce{C2H5OH + 3O2 -> 2CO2 + 3H2O} - Click Render (MathJax mode) to see a beautifully typeset equation.
- Export with Export PNG or Export PDF for reports or slides.
Tip: Use -> for forward reactions, <=> for equilibrium, and include states like (g), (l), (s), (aq).
2) Equilibrium reaction with an expression for Ka
- Reaction:
\ce{CH3COOH + H2O <=> CH3COO^- + H3O^+} - Expression:
$$K_a = \frac{[\ce{CH3COO^-}][\ce{H3O^+}]}{[\ce{CH3COOH}] }$$ - Click Render to typeset both the reaction and the math expression.
Charges use superscripts: \ce{Fe^{3+}}; isotopes: \ce{^{14}_6C}; hydrates: \ce{CuSO4\cdot5H2O}.
3) Redox half‑reaction in acidic solution
- Insert:
\ce{MnO4^- + 8H^+ + 5e^- -> Mn^{2+} + 4H2O} - Switch to Plain text mode if you need quick unicode subscripts/superscripts for emails or chats.
- Use Copy LaTeX or Copy Plain Text to reuse in other editors.
Quick insert templates
- Precipitation:
\ce{AgNO3(aq) + NaCl(aq) -> AgCl(s) v + NaNO3(aq)} - Gas evolution:
\ce{2HCl(aq) + Na2CO3(aq) -> 2NaCl(aq) + H2O(l) + CO2(g)} - Acid–base:
\ce{CH3COOH + NaOH -> CH3COONa + H2O} - Complex ion:
\ce{Cu^{2+} + 4NH3 <=> [Cu(NH3)4]^{2+}}
Need symbols? Try \alpha, \beta, \Delta H, or matrices/align with standard LaTeX math. If a line doesn’t show math, wrap it in $$ ... $$.
Key Features for Chemistry Formatting
ChemAI's LaTeX chemistry editor is built for instructors, researchers, and lab analysts who need clean, standards-aligned markup for digital and print publishing.
- Chemically aware autocomplete surfaces mhchem snippets for acid–base, redox, and organic mechanisms as you type.
- Instant MathJax preview renders balanced chemical equations, isotopes, and equilibrium expressions without leaving your browser.
- One-click exports provide high-resolution PNG and vector-ready PDF downloads for slide decks, lab manuals, or journal figures.
- Plain-text fallback keeps unicode subscripts and superscripts intact for LMS discussions, chat apps, and email summaries.

Frequently Asked Questions
How do I render mhchem formulas correctly?
Use \ce{...} around chemical expressions and click Render. The editor loads MathJax with mhchem extensions, so charges, states, isotopes, and equilibrium arrows display automatically.
Can I export high-quality graphics for publications?
Yes. Choose Export PNG for slide decks or Export PDF for vector-based figures that stay sharp in journals and posters.
Does the editor save my LaTeX between sessions?
