Liminary is an AI-native knowledge platform built for consultants, fractional strategists, and small professional services firms.

It captures content from anywhere you work โ€” articles, PDFs, YouTube videos, AI chat conversations, emails โ€” through a Chrome extension and web app. Instead of just storing what you save, Liminary's AI automatically surfaces the right knowledge when you need it, without you having to search. It synthesizes insights across everything you've collected, fact-checks claims against your sources, detects gaps in your research, and helps you create client deliverables grounded in what you actually know. Use Claude, Gemini, ChatGPT is the same brainstorming session all from one place in Liminary.

If you've ever lost a key stat you know you read somewhere, scrambled to pull together supporting evidence for a recommendation, or wasted hours re-finding research across scattered tabs and tools, Liminary solves that. Save anything.

Your knowledge finds you when you need it.

Questions & Answers

As answered by people managing Supermemory and Liminary.

What makes your product unique?

Liminary's answer:

Liminary is the only tool that covers save, organize, recall, and create in one AI-native workflow. Most tools handle one piece: bookmark managers save links, note apps organize, AI chatbots generate. But none of them connect your actual saved research to what you produce. Liminary does. It ingests anything (articles, PDFs, videos, AI conversations), then proactively surfaces the right knowledge when you need it, without you searching. It also fact-checks your outputs against your sources and flags gaps in your research, something no other tool in this space does.

Why should a person choose your product over its competitors?

Liminary's answer:

If you use Feedly or similar tools to monitor industry trends, you can read but not synthesize or create from what you save. If you use Guru or Glean, you get knowledge retrieval for teams, but it's built for internal company knowledge, not the external research consultants gather for client work. If you use ChatGPT or Claude alone, you get generation but no access to your own saved research, which means hallucinations and no source citations. Liminary connects all of that: capture from anywhere, AI recall with 4x better accuracy than ChatGPT + Google Drive, and creation tools that let you go from research to deliverable without leaving the product.

How would you describe the primary audience of your product?

Liminary's answer:

Independent consultants, fractional strategists, and small professional services firms (1 to 5 people) who bill for their perspective. These are professionals who synthesize large volumes of research into client deliverables like strategy decks, positioning docs, market analyses, and recommendations. Their work depends on the quality and accuracy of the information they bring to the table.

Which are the primary technologies used for building your product?

Liminary's answer:

Liminary is built on an AI-native architecture using semantic ingestion that preserves meaning at sub-document granularity, a context detection engine that predicts what knowledge is relevant to your current work, and an MCP-ready infrastructure that allows integration with other AI tools and agents. Available as a Chrome extension and web app.

  • Building an autonomous Slack agent with OpenCode
    Memory. I use Supermemory for this. Before, Pipa loaded context files and knew to update them. A memory tool adds teammate-like recall: goals, preferences, latest business state, and small details that should carry across runs. Good memory tools also know how to supersede and delete memories, which matters once the agent has more autonomy. - Source: dev.to / about 1 month ago
  • Build a Real-Time Voice RAG Agent for Your Documentation
    We wire everything up with Vision Agents as the voice agent framework, Stream for WebRTC audio and video, OpenAI Realtime for speech in and speech out, Anam so the agent shows up as a face on the video, and Supermemory so answers come from search over your uploaded documents instead of guesswork. The code stays small and most of the behavior lives in one registered function that asks the memory store for relevant... - Source: dev.to / 2 months ago
