Mnemosphere

What is Mnemosphere?

Mnemosphere is a research workspace for people who work with AI all day. It puts ChatGPT, Claude, Grok, and other frontier models in one place so you can compare answers side by side, run prompts in parallel, and move faster. You can turn any answer into a clickable mindmap, highlight key parts, add linked notes, and keep long threads organized with an index. It also lets you chat with YouTube videos, run multiple deep research jobs at once, and use critique mode to spot weak assumptions or missing context. The product is built for researchers, founders, students, and anyone who wants better thinking, not just faster answers.
