MindStash is a curiosity companion that captures links, screenshots, voice notes, and ideas, then uses AI to title, summarize, tag, and connect them into a personal knowledge graph. It resurfaces what matters with timely Sparks, reveals connections across media, and compiles a weekly digest so nothing gets lost. Available on iOS with web and Android, it can also connect your saved context into assistants like ChatGPT and Claude via MCP, turning scattered inspiration into work you can act on.
