Why "Bring Your Own Model" Matters for RPA Documentation

When your RPA documents contain sensitive process data, you need to control where that data goes. Here's why BYOM AI tools are the right choice for enterprise automation teams.

The Data Privacy Problem with AI Writing Tools


Most AI-assisted writing tools work the same way: you paste your content in, it goes to a cloud server, the model generates a response, and you get the output back. Simple. But for enterprise RPA teams, that model has a serious problem.


Your PDDs, SDDs, and process notes contain:


  • Internal system names and architecture details
  • Business process logic that may be commercially sensitive
  • Employee names and roles
  • Customer-facing processes with compliance implications
  • Sometimes: data samples and field values from production systems

  • Pasting any of this into a consumer AI tool likely violates your organisation's data handling policies, your client's NDA, or both.


    The Bring Your Own Model Approach


    BYOM (Bring Your Own Model) means the AI tool connects to a model endpoint that you control — rather than a shared cloud service. The tool handles the document structure, the prompts, and the output formatting. You supply the model.


    In practice, this means:


    Azure OpenAI — if your organisation already has an Azure OpenAI agreement, data stays within your Azure tenant. The same Microsoft enterprise data protection you already have applies. No data leaves your existing boundary.


    Ollama or LM Studio — run a model entirely on your own machine. The data never leaves your network at all, even in transit. GPT-4 level quality is available locally on modern hardware (Llama 3.3, Mistral, Phi-4).


    Your own OpenAI or Anthropic key — data goes to OpenAI or Anthropic under your API agreement, not through a third-party SaaS vendor's shared account.


    Why This Matters More Than You Think


    When you use a SaaS AI writing tool, you are trusting:


    1. That the SaaS vendor doesn't log your prompts

    2. That the SaaS vendor doesn't use your data for model training

    3. That the SaaS vendor's security posture is adequate

    4. That their data processing agreement covers your use case


    With BYOM, you remove that dependency entirely. Your data goes where you already decided it's allowed to go.


    What DocForge Does


    DocForge is a desktop application — it runs on your machine, not in a browser tab backed by a cloud server. You configure your own AI endpoint in Settings:


  • Your own OpenAI API key → data goes to OpenAI under your agreement
  • Azure OpenAI endpoint + key → data stays in your tenant
  • Ollama running locally → data never leaves your machine
  • Any OpenAI-compatible endpoint → works out of the box

  • DocForge itself never sees your content. It connects directly from your machine to the model endpoint you specify.


    The Cost Advantage


    As a side effect, BYOM is also significantly cheaper than SaaS AI tools. GPT-4o-mini costs roughly $0.15 per million input tokens. A full PDD generation — even with a detailed transcript — typically uses 2,000–4,000 tokens. That's less than $0.001 per document.


    Compare that to AI writing tool subscriptions at $20–$50/month, and the economics are clear — especially if you're generating dozens of documents per month across a delivery team.


    Enterprise-Ready From Day One


    DocForge was built for RPA consultants who work with enterprise clients. Data privacy isn't an afterthought — it's the architecture. BYOM means you can use DocForge with confidence in any environment, from a regulated financial services client to a healthcare provider with strict data residency requirements.
