• Rewrites prompts for a chosen model
• Modes for different tasks
• Free open models or your own key

Mexger apps

• CAD Studio — Free AI CAD in your browser: describe a part and get parametric solids with exact booleans, ISO holes, involute gears and assemblies. Measure, section, explode, sketch in the air with your hands, and export watertight STL and STEP.
• Aimplify — Describe a gadget and AI designs the circuit and code, checked by wiring rules and the real Arduino compiler. Simulate Arduino and Raspberry Pi Pico, analog circuits with ngspice, Verilog on FPGAs, then turn it into a routed PCB with Gerbers for JLCPCB or PCBWay. Free.
• UlChats — Import a WhatsApp chat and talk with an AI that has learned their voice from your whole history together — with memory you can see and edit, and care built in. Encrypted before it is stored.
• Textem — Share a 4-digit code that works once; they enter it, you accept. End-to-end encrypted chats, photos, voice notes, view-once media, and voice and video calls — messages that disappear when you want them to.
• PromptArm — Write a raw prompt, pick a mode and a model, and PromptArm rewrites it into a form that gets the most out of the AI you are calling. Free with open models.
• Discover — AI apps, models and skills in the store.
