Mnemosphere

Mnemosphere is an AI research workspace that puts leading models from multiple labs into one interface. Users can compare answers from several models side by side, run parallel prompts, and launch multiple deep-research tasks at once. It also adds tools that are useful for long research sessions, including one-click mindmaps, AI answer critique, inline highlighting, notes, conversation indexes, and YouTube transcript intelligence. Files such as PDFs, spreadsheets, images, code, and webpages can be added as context. Mnemosphere also supports web search with cited answers. It is designed for researchers, founders, analysts, product managers, and other professionals who need to compare model responses and turn large amounts of information into structured insights.
