Multisense — AI Chatbot App with GPT Integration
A Flutter AI chatbot app with real-time GPT conversations, multi-modal input (text, image, audio, PDF), smart chat history categorisation, and Stripe-gated premium model access.
The problem
General chat apps take text and nothing else. Users wanted to ask about an image, a voice note or a PDF, and still find the thread a week later.
The hard part
Four input modes normalised into one conversation model, with chat history that categorises itself instead of growing into a flat log, and Stripe gating premium model access at the server so the paywall isn't a client-side check.
Outcome
Delivered end to end, including the Stripe-gated premium tier.
Where it lives
Client-owned build, listing managed by the client.
