Direito Facil IA is a WhatsApp based assistant that helps people with limited educational background to access Brazilian social services easily by just having a conversation with Direito Facil. Unique features of the App are:

  • Fact based grounding in the answers by restricting it to the Vertex AI Search App
  • Portuguese Simples based language simplification for users
  • WhatsApp features - text, voice and location pins work seamlessly.

Future improvement

  • Allow the agent to help fill out forms on behalf of the users based on information provided by them. Basically close the loop end to end.

The App works using a Python FastAPI backend coupled with multiple other services like the ones listed below. AI assisted coding tools like codex and antigravity were used to create the Application.
Gen AI Model: Gemini 3.1 Pro
Vertex AI Search App for grounding answers to a curated dataset
Cloud TTS (Chirp HD) service for sending voice messages to users

We did all the data research and prepared cleaned up datasets we could directly feed to the RAG engine. We also examined several parts of our tech stack for feasibility of implementation but did not start coding until saturday night.

Twillio Sandbox acocunt came in handy when we could not get WhatsApp Business Account set up. ngrok helped us run the app from our computer instead of deploying to the cloud.
