Translation that has the full context.
Generic translation is context-blind. Subsume learns your terminology, your speakers, and your house style—then delivers context-informed translation, live, in 100+ languages on any device.

Terminology, speaker conventions, and session context applied live.
What it is
Subsume is a context-aware translation engine for live speech. It learns your terminology, speakers, and style and applies them to the live translation path—so multilingual audiences get output shaped for your event instead of a stateless pass. Real-time captions and optional AI dubbing come built in.
What it solves
- Accessibility for hard-of-hearing audiences
- Language barriers for multilingual attendees
- Readable, polished captions for live settings
- No-install viewer links for phones and projectors
Who it's for
Designed for event organizers, educators, creators, houses of worship, and teams that want reliable live captions and translations for in-person or remote audiences.
The engine
Context, layer by layer.
Generic machine translation is stateless—it forgets everything between sentences. Subsume applies five context signals at defined points in the workflow, with recurring-session lessons carried forward where the product supports them.
Glossary
Your terminology, carried forward. Names, acronyms, and domain terms can stay consistent, and learned terms merge back into a recurring template after a session.
Speaker
Per-speaker profiles. Timing and cadence adapt to how each person actually talks, so translations land in natural, complete lines.
Style
A live style brief. Formality, tone, and house conventions—honorifics, capitalization, phrasing—are captured and applied across every language.
Domain
Domain priming. Flag a session as medical or faith-based content and the engine adapts—medical-tuned speech recognition, theological terminology—so terms of art survive, not just words.
Coaching
A feedback loop. A quality monitor critiques translations and synthesizes useful lessons back into the template for the next recurring session.
In the product
What context-aware actually means.
Context is not a label added after translation. You can see where it enters the workflow, when it is applied, and what carries into the next recurring event.
Tune the event
Choose the source and audience languages, describe the topic, then run Tune to generate a language-specific refinement guide.
Attach speaker context
Pick one speaker profile to apply key terms, repeat corrections, and learned cadence at the source before translation.
Apply context live
The live path combines the guide, glossary, speaker context, recent captions, and style signals for each audience language.
Carry useful lessons forward
Learned terms and synthesized coaching can merge back into the template; a separate digest can produce a polished record.
Human control still matters
Hosts choose the topic, guide, profile, audience languages, and output mode. AI translation remains probabilistic; use qualified human review when a clinical decision, legal obligation, or other high-stakes outcome depends on exact wording.

How it works
Three steps to live translation.
Set the context, translate while you speak, and share one no-install audience experience.
Create a session
Pick source and audience languages, describe the topic, then Tune the per-language guides before you go live.
Translate while you speak
Speak naturally. Captions and translations update in real time with your selected context applied.
Share with your audience
Viewers open a link or QR code on any device, choose their language, and read or listen when dubbed audio is enabled.
