Self-hosting
Deploy the SmileSub subtitle system on your own server or private cloud — footage, subtitles and account data stay under your control
Why self-host
Data stays inside your network
Media, subtitle text and account data live on your own servers and never reach our database. A good fit for teams with content-security, trade-secret or privacy requirements.
Configuration-level customization and white-label
Interface copy, branding, default parameters and integrations can be adjusted. You receive a container image and a licence file, not the source code; source-level licensing is available separately.
Recognition engine can run locally
Choose the cloud engine (faster, higher accuracy) or run recognition locally on your own hardware so footage never leaves the network. Local inference requires a GPU (16GB VRAM recommended); throughput depends on your machine.
Core advantages
Licence plus annual maintenance — not a one-off buyout
The first year includes deployment assistance, updates and support. From year two, renewal is 15% of the licence price per year. If you do not renew, updates stop but the product keeps working.
You decide the data boundary
The cloud recognition engine is the default, and on that path audio does leave your network (we do not retain it). When footage must never leave, switch to the local recognition engine.
Multilingual recognition + smart translation
Speech recognition covers Chinese, English, Japanese and Korean as source languages; translation covers 20 languages, and can connect to a service you specify.
Multiple export formats
Export to mainstream subtitle formats such as SRT, VTT and ASS, ready for all kinds of editing software.
Dedicated technical support
Deployment assistance, training, troubleshooting and version upgrades, with a 1–2 business day response on working days.
Scalable architecture
Containerized with Docker, so scaling clusters, load balancing and distributed processing are straightforward.
Who it is for
Media production companies
High daily volume of video subtitle work
Educational institutions
Automatic subtitles for course videos
MCNs / independent creators
Batch production of short-video subtitles
Corporate training
Subtitles for internal meeting and training videos
