PlusB

PlusB is an all-in-one AI assistant platform that combines multiple frontier models and creative tools in a single workspace for people who don't want to juggle separate subscriptions. Instead of paying for ChatGPT, Claude, and Gemini individually, PlusB lets you chat with GPT-5.5, Claude, and Gemini side by side, then switch to adjacent tasks without leaving the app. Concrete capabilities span text chat, AI image generation, AI video creation, code writing and debugging, deep research, and automated presentation building. That breadth positions it as an "AI OS" — a hub where a knowledge worker, developer, marketer, or student can research a topic, generate supporting images, draft and debug code, and assemble a slide deck in one continuous flow. Because it aggregates several third-party models under one interface, PlusB is best for users who value consolidation and model comparison over the deepest single-vendor feature set. The product is early-stage (a Product Hunt launch with a YC application association), so long-term reliability, model version currency, and documentation depth are still unproven. Pricing is not published on the sources available, so verify current plans and any free tier directly on the PlusB site before committing.

Knowledge workers, developers and students use PlusB to chat with multiple AI models and generate images, video, code, research and slides in one app.
