A conversation about your business
A customer sends a message. You check a few details, look at your calendar, prepare a response, and copy the information into another system. By lunchtime, you’ve repeated that process several times.
Which parts really need your attention, and which parts follow a predictable pattern?
Hi, I’m Jorge, the person behind Kai Digital. Through ClientRain, I offer AI automation, focused AI security audits, and guided app building. Everything starts with a conversation about your business.
We choose one process worth improving, agree a manageable scope, and test the result. You stay involved where your judgment matters, with explanations that help you understand the choices along the way.
How I approach your business →Three ways to work together
Organize incoming requests, prepare draft replies, or update a dashboard. Start with one useful workflow and keep a person in control of important decisions.

10 launch spots · 15 minutes · No cost
We are opening 10 free 15-minute consultations for new clients. Tell me about your business and leave with a practical next step. One consultation per business; spots are allocated in order of complete requests and confirmed by email, subject to scheduling availability.
We meet face to face over Google Meet, in English, Spanish or German. We discuss your goal, see whether we are a good fit, and recommend where to start. The consultation does not include development, implementation or security testing. No card and no obligation to purchase.
Complete the short intake form to request a spot. Sending a request does not confirm a spot. If the round is full, we will tell you and you can freely choose another option.
Explore paid sessions →Your app. Your know-how.
Bring an idea for a customer portal, an internal dashboard, or a tool that helps your team stay organized. We can build it together, with explanations along the way.
Ask “Why are we doing it this way?” or “Could we make that simpler?” Understanding those choices helps you maintain your app and decide what to build next.
Choose one problem and a useful first version.
You work in your own accounts while I explain the decisions.
Practice a change, test it, and leave with notes you can use again.

Security for AI-enabled work
The audit starting at USD 490 covers a focused review of configuration, permissions and data flow for one AI app or agent, with a report and walkthrough. Active testing, source-code review, multiple systems, remediation and retesting require a separate scope and quote. Testing requires written authorization. This is a scoped assessment, not certification or a guarantee of security.
An inventory of the agreed scope, evidence-backed findings, priorities, recommendations and review limits. If you need active testing, we define and authorize it explicitly before work begins.
Reference framework: OWASP Top 10 for LLM Applications (2025). Applied where relevant to scope; this does not imply OWASP certification.
Discuss my AI systemFrom a goal to useful work
01 / CONTEXT
Tell me what repeats, which tools you use, and what you would like to improve. We start with examples that do not contain sensitive data.
02 / SCOPE
We define the scope, deliverables, timing and price before project work begins. You know what we are testing and how we will evaluate it.
03 / WORK
Is it saving time? Are the results accurate? What happens with an unusual request? Use what we learn to choose the next step.
Before we begin
Guided building is the starting point: you work on your app while I explain how to design, test and change it. If you prefer to delegate, implementation is scoped and quoted separately.
You can start without programming experience. We choose suitable tools and a manageable first version. You will still need time to practice and check the results.
We agree the app, workflow, accounts and permitted activities before work begins. Typical topics include prompt injection exposure, sensitive data, tool permissions, output handling and approval boundaries. Coverage and untested areas are listed in the report.
For a scoped project, we confirm the deliverables and full price before sending a payment request. For a guided session, use the available payment link or request one by email. After payment, propose three times; your appointment is confirmed by email. Payment alone does not reserve a time.
ClientRain is operated by KAIDIGITAL SPA, a Chilean technology company. We work remotely with US and international businesses, primarily in English. Spanish and German are also available.
