How I built a ServiceTitan chatbot with Lovable
I ran an HVAC company, not a software company. I built my own private ServiceTitan chatbot with Lovable, without writing code by hand. Here is exactly how it fits together, and how you can build your own tools the same way.
The whole idea in 40 seconds
What the video shows
- ServiceTitan holds your data.
- Titan Connect reads it, read only.
- You ask questions in plain English.
What is Lovable?
Lovable is an AI app builder. You describe what you want in plain English in a chat, and it builds a real web app: the screens, the database, the sign-in, and the hosting. You keep changing it by chatting, the same way you'd explain a job to a new hire.
Why this matters for contractors
You know the problem
You know which questions you ask every Monday morning. That is the hard part, and you already have it.
No coding background needed
If you can describe a process step by step, you can describe an app.
You own it
The app lives in your own Lovable account, not in some vendor's software.
Other tools a contractor could build with Lovable
- A membership renewal tracker
- A quote or price calculator for your techs
- An internal dashboard for your managers
- A hiring and onboarding checklist app
How Titan Connect fits together
ServiceTitan
your data: jobs, invoices, estimates, memberships, equipment
AI chat
ask in plain English. Pick Gemini, Claude, or ChatGPT models, running on Lovable AI
- Read only
- It never writes back to ServiceTitan.
- Your copy
- It runs in your own Lovable workspace with its own database.
- Honest answers
- When data is missing (for example, equipment records with no install date), it says so instead of guessing.
Step by step: how to build your own
This is the same path I took. You can follow it from scratch for free, or use the course to skip straight to a working copy.
Step 1. Write down your questions first
Before you touch any software, list the 10 questions you wish you could just ask ServiceTitan. Examples: Which estimates are still unsold? Which members are due for a visit with nothing scheduled? Which installed equipment is aging with no replacement quote? Which marketing campaigns actually pay off? These questions become your app.
Step 2. Create a Lovable account and start a project
Describe the app in plain English. Here is a prompt you can start with:
Example promptBuild a private, read-only dashboard and chat app for my ServiceTitan data. It should have a setup wizard where I paste my ServiceTitan API credentials, pull my jobs, invoices, estimates, memberships, customers, locations, and installed equipment into my own database, refresh that data on a schedule, and let me ask questions about it in plain English. It must never write anything back to ServiceTitan.Step 3. Get ServiceTitan API access
You need ServiceTitan admin rights. You create an app inside your own ServiceTitan account, give it read-only access, and it gives you a few credentials. You can turn that connection off yourself, any time.
Step 4. Keep your credentials secret
Store them in Lovable's backend secrets, never pasted into the page or the code, and never in a chat with anyone.
Step 5. Pull your data into tables
Ask Lovable to create one table per area (jobs, invoices, estimates, memberships, equipment, and so on) and to fill them from ServiceTitan. Start with a short date range so pulls finish fast, then widen it.
Step 6. Build starter reports for your most common questions
Saved reports answer in a couple of seconds, so your Monday questions don't wait on the AI to figure things out each time.
Step 7. Add the chat, and make it honest
Tell Lovable the chat must answer only from your data, show the numbers it used, and say plainly when something isn't in the data. A tool that makes up a number is worse than no tool.
Step 8. Check it against numbers you already trust
Before you act on an answer, compare a few results to the ServiceTitan reports you already know. Fix what doesn't match, one change at a time.
What I learned building it
- Make one change per message so you can see what broke.
- Use Lovable's plan mode to talk through a big change before it writes code.
- Be specific: name the table, the field, and the exact answer you expect.
- Keep it read only. Don't give a tool write access to your ServiceTitan unless you truly need it.
Two ways to start
Build it yourself
Use this guide, start a Lovable project, and build your own version from scratch.
Start building on LovableStart from my working app
Buy the DIY ServiceTitan Chatbot course and you get a remix of my working Titan Connect app: a ready-made copy in your own Lovable workspace. You start from an app that already works instead of building from scratch. The course walks you through remixing it and connecting it to your ServiceTitan, click by click.
