You will get Ari AI Agent, Manage everything via dashboard or WhatsApp. Same system.
Project details
Ari is an AI system that lets you manage your workflows from a single dashboard or directly through WhatsApp.
Track tasks, calendar, finances, reminders, and more in one place. Use the dashboard when you want full visibility, or send a message or voice note on WhatsApp when you want something done.
“Show my tasks for today”
“Update my expenses”
“What’s on my calendar?”
Ari doesn’t just respond, it executes.
Behind the scenes, it connects with tools like Google Sheets, Calendar, and other APIs to automate real workflows. No app switching. No manual updates.
This isn’t a chatbot or a demo system. It’s built to reduce operational work and bring everything into a single, working system. Also supports both cloud APIs (OpenAI/Gemini) and local LLMs (Ollama) for privacy-conscious applications.
Tech Stack: Python, FastAPI, React, OpenAI/Gemini/Ollama, WhatsApp Business API, Whisper (Voice processing), Google Workspace APIs.
