Have you ever thrown something away because you didn't know how to fix it? A hole in your favorite sweater. A loose sole on a sneaker. An open seam on a bag you use every day. You still want to keep it, but buying a replacement feels easing than figuring out the repair. That's why I built Mendlet. Mendlet is an AI repair assitant that helps you turn a photo of the damage into an easy to follow repair plan. It first highlights the affected area, suggests the materials you'll need and walks you through the repair. Behind the scenes, Muse Spark analyzes the damage and creates the instructions, while SAM 3.1 marks the damaged area in your photo. If you get stuck, you can ask a question by voice. Muse Voice transcribes your question and Spark answers it in the context of the repair. Muse Image generates a preview of what the repaired item should look like. Mendlet supports textiles, shoes and selected low-voltage electronics. When a repair isn't suitable for guided DIY work, it can recommend professional help or replacement.
