Talk to LaTeX — Speak math. See it typeset.

Watch sound become math

From a mumble to a manuscript,
in one breath.

This runs live, right here. Your voice is inhaled as noise — and exhaled as perfect, typeset mathematics.

Talk to LaTeX listening…

In action

It knows the classics by heart.

Name a standard object and it inserts the real thing — not a placeholder. These are all genuine, live-rendered output.

say “insert the Minkowski matrix” — get exactly this

How it works

Hear · Think · Type.

Three steps, milliseconds apart. You never touch a keyboard for the math.

01

Hear

Hold the hotkey and speak naturally — fillers, false starts and all. A live level-meter shows it’s catching every word, then OpenAI Whisper transcribes it.

Sonnet 4.6balanced

Haiku 4.5fastest

02

Think

Claude turns the transcript into correct LaTeX — resolving “x over y plus one,” honoring “scratch that,” and choosing the right model automatically.

42 Let $f(x)=\int_0^1 e^{-x^2}\,dx$

03

Type

The compiled LaTeX is pasted straight at your cursor — in Overleaf, your editor, anywhere — and your clipboard is restored untouched.

Features

Small details, big fluency.

Everything tuned so the common case feels instant and the hard case still feels right.

Push-to-talk or hands-free

Hold the key for a quick phrase, or double-tap to toggle hands-free for a long derivation. Tap once to send, Esc to cancel — nothing gets pasted by accident.

Named objects, for real

Say “the Pauli matrices,” “the identity matrix,” or “Euler’s identity” and it writes the actual object in LaTeX — never a text placeholder.

Auto model routing

Short and simple? It uses Haiku for Wispr-speed. Matrices, integrals, proofs? It escalates to Opus — automatically, with no added latency.

Understands corrections

Change your mind mid-sentence. Say “scratch that, start now” and everything before it is dropped — only what you meant gets written.

Local history

Every dictation — what you said and the LaTeX it became — is saved locally, so nothing you’ve typeset is ever lost.

Made for Overleaf — and everywhere else

It pastes at your cursor system-wide, so it drops cleanly into Overleaf, your local TeX editor, Markdown notes, Slack — anywhere you can type. Inline $…$ for short bits, a full equation environment for the showstoppers, decided for you.

Get it
