Live captions · Translation

One voice. Every language. Live.

Live captions and translations your audience can follow on any device.

Reach the world.

No credit card required.

Subsume translates live speech into more than 155 language variants.

How it works

From speech to every screen, in moments.

01

Speak

Start a session and talk. Speech becomes clean, punctuated captions in real time — with AI tidying fillers and phrasing as you go.

02

Translate

Every line streams into the languages your audience chose — 155+ regional variants, refined by AI that learns your terminology.

03

Share

Your audience scans a QR code or opens a link. No installs, no apps — captions follow on any phone, tablet, or projector.

Self-improving

Every session starts smarter than the last.

Subsume keeps learning between sessions — the vocabulary it hears, the pace each speaker talks at, the translation style your audience prefers. It all syncs back automatically when a session ends.
