Analysts have to make sense of foreign-language broadcasts, field and intercepted audio and captured documents — yet sending any of it to a cloud translation service is a non-starter when the source is sensitive. TransCastAI transcribes and translates speech, recordings and documents entirely on-device, so the material is understood in English without ever leaving your machine.
A sample of the everyday capabilities that matter for Defence & Intelligence.
Every transcription and translation runs on the analyst's own machine. No cloud, no external API, no audio or documents crossing your security boundary.
Not just text. Monitor live foreign broadcasts, transcribe field and intercepted audio, and translate captured PDFs and files — all in one workspace.
Military, geopolitical and technical terms are trained into the models, so domain language and named entities come out right rather than as broad-strokes machine translation.
English ⇄ Farsi and English ⇄ Arabic today, both directions — with Chinese, Russian and Ukrainian in training — tuned for the foreign-source-into-English work analysts do most.
TransCastAI runs entirely on-device on macOS today (Apple Silicon and Intel) — nothing is uploaded, no account is required to start, and the material never touches a third-party server. Private-server, cloud and fully air-gapped deployments are on the roadmap for teams that need a shared, offline enclave with no internet reachable at all. The product is designed to ISO 27001 and NIST CSF controls; we do not claim certification.
The on-device engine works with no internet connection — no external API calls, no telemetry — so it runs inside closed networks and in the field, today, on macOS.
Domain terms — military, geopolitical, technical — are trained directly into the models, not bolted on, so field vocabulary and named entities translate consistently.
Live broadcasts, field recordings and intercepted audio are transcribed and translated directly, alongside PDFs, Office files and other captured documents.
Nowhere. All transcription and translation happens on the analyst's own machine — no uploads, no external API, no telemetry — and no account is required to start, so no data trail leaves your security boundary. Private-server and fully air-gapped deployments for shared teams are on the roadmap.
Specialist military, geopolitical and technical terminology is trained directly into the models, so domain terms and named entities come out consistently rather than as literal machine translation. English ⇄ Farsi and English ⇄ Arabic are supported today in both directions, with Chinese, Russian and Ukrainian in training, and terminology can be extended for your specific domain.
TransCastAI is on-device on macOS today (Apple Silicon and Intel); a Windows edition is in development, and private-server, cloud and air-gapped deployments are on the roadmap. It is built to ISO 27001 and NIST CSF controls — we do not claim certification. Licences are per device; start a conversation and we'll scope a pilot and pricing for your team.
Start a private, on-device trial on your own hardware — no account, nothing uploaded — or talk to us about a pilot, specialist terminology for your domain, and roadmap deployments for air-gapped teams.
