Search over a thousand math and text symbols by name or meaning, or draw the one you're thinking of. Click any symbol to copy its command.
Type what the symbol is called or what it means: not equal, infinity, therefore, subset, degree, euro. You can also paste the character itself, like ≤ or ∀, and the search finds its command.
If you don't know the name, draw it in the box. Recognition runs on your device using Detexify's community handwriting samples, so it's instant and works offline once loaded. Click a result to copy its command.
Most symbols are maths and must sit inside math mode: $\alpha$ in a sentence, or inside \[ ... \] and equation for displayed formulas. Typing \alpha outside math mode stops the compile with “Missing $ inserted”.
Text symbols such as \textdegree, \S or \textregistered go straight into running text. Each symbol on this page says which mode it needs.
The angle is $\theta = 45^\circ$, so $\sin\theta \approx 0.707$. \[ \forall \varepsilon > 0 \; \exists \delta > 0 : |x - a| < \delta \Rightarrow |f(x) - f(a)| < \varepsilon \]
Core LaTeX and amsmath cover the common Greek letters, operators, relations and arrows. Many others live in packages: amssymb (for example \mathbb, \therefore, \leqslant), stmaryrd, wasysym, marvosym, textcomp and more. When a symbol needs one, it's shown next to the command.
Add the package once to your preamble with \usepackage{amssymb}. In Samskrift's editor, inserting a symbol from the palette adds the package for you.
Relations: \leq ≤, \geq ≥, \neq ≠, \approx ≈, \equiv ≡, \sim ∼, \in ∈, \subseteq ⊆. Operators: \times ×, \cdot ·, \pm ±, \div ÷, \cup ∪, \cap ∩.
Arrows: \to →, \Rightarrow ⇒, \iff ⟺, \mapsto ↦. Big operators: \sum ∑, \prod ∏, \int ∫, \oint ∮. Misc: \infty ∞, \partial ∂, \nabla ∇, \forall ∀, \exists ∃, \emptyset ∅.
\usepackage{...} to your preamble.Samskrift is a collaborative LaTeX editor in your browser: these tools are built in, the PDF compiles next to your source, and your co-authors can type in the same file.
