AI Interior Design Assistant: Redesign a Room From a Telegram Chat
A Telegram bot I built that acts like an interior designer. You send a room photo and chat with it, and it generates a redesign, edits it on request, marks up the blueprint, and answers questions, all in the chat.
The idea
I wanted an interior designer you can just talk to. Send a photo of your room, say what you want, and get a real redesign back, without an app, a login, or a call. So I built it as a Telegram bot.
How it works
Everything runs through Telegram. You message the bot, and the first thing it does is work out what you are actually asking for. It routes plain messages, quick button taps, and uploaded files down different paths so each one is handled properly.
For the design itself, you can set the details with quick taps: the room, the style, the palette, the mood, and the blueprint. The bot takes your room and your choices and generates a new design with Gemini’s image model, then sends the finished image straight back into the chat. Ask for a change and it edits the last design instead of starting over, so you can go back and forth until it looks right.
It can also mark up a blueprint. It annotates the plan, converts it to a file, and sends the marked-up version back, so the visual and the layout stay in sync.
Behind the chat there is a design assistant with a knowledge base and memory. It answers questions, keeps track of the conversation so it does not forget what you already told it, and captures a brief as you go. Typing indicators and clean replies make it feel like you are messaging a person, not a form.
Why it is built this way
The hard part of a project like this is not generating one image. It is handling a real back-and-forth: taps, text, and files all mixed together, edits that build on the last result, and enough memory that the bot stays in context. Routing every kind of input to the right path and keeping state between messages is what makes it feel like an assistant instead of a one-shot image tool.
The result
A full interior design loop that lives inside a chat. You send a room, shape the direction with a few taps, and get back a design you can keep refining, plus a marked-up blueprint and answers to your questions, all without leaving Telegram.
