Liminary is an AI-native knowledge management and recall tool that turns everything you save—web pages, PDFs, YouTube videos, meeting transcripts, and ChatGPT/Claude/Gemini conversations—into a connected knowledge graph that acts as working memory. Built for research-heavy knowledge workers like consultants, analysts, investors, journalists, and founders, it proactively surfaces your own relevant saved sources as you write in tools like Google Docs and Notion, rather than making you search. Its main differentiator is proactive, source-grounded recall with built-in fact-checking against your own library instead of the open web.

Generates and rewrites AI content so it reads naturally and passes AI-detection tools. Used for business writing, articles, and content that needs a human tone — one of the fastest-growing tools in recent mentions.
