AI Integration · Security
AI features can save your team hours every week, but only if client data stays protected. These eight principles show how to add them safely.
Adding an AI feature to a business app is now one of the most requested upgrades: summarise this document, draft this reply, sort these incoming files. The technology is easy to connect. The harder part is doing it in a way that does not leak client information, run up a surprise bill or put unchecked AI output in front of a customer.
This guide is written for founders and owners of firms that handle sensitive information, such as law, accounting and consulting practices. It covers the risks, eight design principles, practical use cases and a simple way to start. It is general guidance, not legal advice, so check your own confidentiality and regulatory obligations.
The five risks to design around
- Exposed keys. If your AI provider key sits in the browser, anyone can use it and you pay the bill.
- Sensitive data sent unnecessarily. Every field you pass to a model is data leaving your system.
- Confident mistakes. AI can produce fluent, wrong answers. In legal and financial work that matters.
- Runaway cost. Usage is billed per request, so a loop or a heavy user can get expensive fast.
- No audit trail. If you cannot say who asked what and when, you cannot investigate a problem.
Eight design principles
1. Call the AI from the server side only
In Bubble, make AI requests from backend workflows and store the provider key as a private credential in the API Connector. The browser should never see it. See our security best practices for the wider picture.
2. Send the minimum necessary data
Pass only what the task needs. Strip names, account numbers and identifiers where the task does not require them, and refer to records by internal ID rather than by personal detail.
3. Understand the provider’s data terms
Read how your chosen provider handles data sent through its business or API offering, including retention and whether it is used for training. Terms differ between providers and plans and change over time, so verify them before sending anything sensitive.
4. Keep a person in the loop
For anything client-facing, let the AI draft and a human approve. The goal is to remove the blank page and the repetitive work, not the professional judgment.
5. Log every AI request
Record who triggered it, when, which feature used it and the approximate cost. This gives you accountability and cost visibility from day one.
6. Put limits on usage
Cap requests per user or per plan, and set alerts for unusual volume. Remember there are two costs: the provider’s usage charge and your Bubble workload. See workload units explained.
7. Apply privacy rules to AI results too
A summary of a confidential matter is itself confidential. Store AI outputs against the record they belong to, and make sure the same access rules that protect the record protect the output.
8. Test with hostile and messy inputs
Uploaded documents can contain instructions that try to steer the model, a problem known as prompt injection. Test with unusual, empty and adversarial inputs before launch, and avoid giving the AI the ability to take actions on its own without confirmation.
Practical use cases and their safeguards
| Use case | Risk level | Safeguard |
|---|---|---|
| Summarise matter notes or meeting notes for staff | Medium | Staff-only, reviewed before use, minimum data sent |
| Classify incoming documents (invoice, contract, ID) | Low to medium | Human confirms the category before filing |
| Draft routine client updates | Medium | Always approved by a person before sending |
| Extract fields from invoices or forms | Medium | Show the source beside the result for checking |
| Answer common questions from the firm’s own guidance | Medium to high | Limit to approved content, show sources, escalate to a person |
| Give clients legal or tax advice unattended | High | Do not do this |
A sensible way to start
- Choose one workflow that is repetitive and low risk.
- Write down what data it needs and what it must never see.
- Build it with the safeguards above, for staff use only.
- Run it for a few weeks, measure the time saved and review the mistakes.
- Only then consider client-facing features.
A pilot like this is usually a small project, and it works best when it sits inside a proper system with roles and privacy rules rather than a loose plugin. Builds start at $3,500, and our Discovery Sprint can scope the AI feature and the system around it for $345, credited toward the build.
Frequently asked questions
Is it safe to put client data into ChatGPT-style tools?
It depends on the data, the provider’s terms, your obligations and how the integration is designed. Treat it as a deliberate decision, not a default. When in doubt, send less data and check with your regulator or counsel.
Can I use more than one AI provider?
Yes. A well-designed integration keeps the provider behind your own backend, so you can switch or add providers without rebuilding the app.
What does AI usage cost?
Providers bill per usage, and the amount depends on how often it is used and how much text is processed. Logging and limits keep it predictable.
Will the AI replace my staff?
In our experience the better framing is that it removes repetitive drafting and sorting so skilled people can spend time on judgment and clients.
