About

PrimeThink

Features
Read full description

PrimeThink is the AI workspace that keeps your context yours, independent of any single AI provider. Most AI tools capture your institutional knowledge and lock it inside their model. PrimeThink flips that. It sits above the models as a context and reasoning layer, so your workflows, documents, and organisational memory stay with you while you switch freely between Claude, GPT, Gemini, Mistral, DeepSeek, and open-source models. On mobile, that means asking questions of your own data in plain language instead of navigating complex dashboards. Pull up records, capture meetings, and turn them into reusable memory your team can act on later. Full productivity, from your pocket. What PrimeThink solves: - AI fragmentation: one platform instead of a dozen disconnected tools, with a shared workspace where people and AI assistants work together in real time. - Vendor lock-in: a model-agnostic architecture that keeps you free to choose the best model for each task, and to change your mind. - Technical barriers: build working applications by describing them in natural language, no code required, so domain experts create workflows directly. - Context ownership: your knowledge lives in the platform, not the model, giving you a durable layer that outlasts any provider. PrimeThink turns scattered AI usage into a single, governed workspace: collaborative, model-neutral, and built to keep humans in control of the intelligence they use.
