How WortKai works, step by step.

Follow one dictation from your voice to finished text. The yellow dot is your data moving through the system: your PC, your Supabase server, OpenAI, and back into the app you're typing in.

    Where everything runs.

    Four building blocks. Your text and history stay on your PC; the server only passes requests to the AI after checking who you are and your limits.

    Your PC: WortKai app
    • Listens for the shortcut, double-tap Space and Ctrl+C
    • Keeps the mic ready; cuts speech into pieces at pauses
    • Cleans text locally (fillers, digits) and pastes it
    • History, notes and dictionary stay on the PC
    • Sign-in session encrypted by Windows
    Supabase: your server
    • Google sign-in and tokens (renewed hourly)
    • Edge function: the only door to the AI
    • Checks invite list and daily limits, books usage
    • Holds the OpenAI key; it never reaches a PC
    Next: usage dashboard in Grafana, EU region
    OpenAI: the models
    • Speech-to-text: gpt-4o-mini-transcribe, gpt-4o-transcribe after the server update
    • Text: gpt-4.1-mini for clean-up, translation and notes
    • Rewrite: gpt-4.1 (falls back to mini)
    Next: EU data processing
    Cloudflare: delivery
    • wortkai.com website (Worker, Access login)
    • App updates from R2 at wortkai.com/updates
    • Apps check every 4 hours and after waking
    • Private finance page
    Next: Payload CMS for texts and blog
