ChatGPT or Liminary

Choose between a conversational thinking partner (ChatGPT) or a persistent memory system (Liminary).

Choose Liminary if you're tired of re-uploading the same documents to every new AI session and want your AI to actually remember you.

ChatGPT is the most widely used AI tool in the world. Millions of professionals use it daily to draft, brainstorm, analyse, and iterate. Its conversational interface and reasoning capabilities have changed how knowledge workers approach their craft.

But ChatGPT has a fundamental limitation that every serious user has encountered: it forgets everything between sessions. Every conversation starts from zero. The context you carefully built yesterday, the documents you uploaded, the nuances you explained about your client, all gone.

Where ChatGPT stops

ChatGPT is a conversation engine. It's excellent at generating, analysing, and refining content within a single session. Projects and Custom GPTs add some persistence by letting you upload files and set instructions. But the knowledge doesn't follow you outside of ChatGPT, and it certainly doesn't surface while you're writing in Google Docs or preparing for a meeting.

The consultants we interviewed described the pattern clearly. They upload the same client documents at the start of every session. They re-explain their methodology, their tone preferences, their client's situation. One told us: "I spend more time getting the AI ready than I spend writing."

ChatGPT is also a single tool. If you switch to Claude for synthesis or Gemini for research (as many professionals do), none of your ChatGPT context comes with you. Your carefully trained Custom GPT, the voice it learned, the preferences it absorbed, all locked inside one platform.

Where Liminary goes further

Liminary is not a replacement for ChatGPT. It's the persistent knowledge layer underneath it.

Save your research, your client documents, your meeting transcripts, and your web bookmarks into Liminary collections. That knowledge persists across sessions, across days, and across tools. When you write in Google Docs, Recall surfaces relevant context from your entire knowledge base without you asking for it.

You can keep using ChatGPT for what it does best: reasoning, drafting, and conversation. Liminary ensures you never have to re-upload, re-explain, or re-establish context again.

What Liminary adds that ChatGPT doesn't

Persistent knowledge base. Your research, documents, and meeting notes accumulate over time and remain queryable indefinitely. Nothing resets overnight.

Recall in Google Docs. Relevant knowledge surfaces in the sidebar while you write. ChatGPT requires you to leave your document, switch to ChatGPT, ask a question, and bring the answer back.

Chrome extension. Save anything from the web to your knowledge base with one click. No copying and pasting into chat windows.

Google Meet integration. Meeting transcripts flow directly into your collections. In ChatGPT, you would need to manually paste a transcript into a conversation.

Competitive intelligence agents. Agents monitor companies and topics on a schedule. ChatGPT has no background monitoring.

Fact-check and gap detection. Liminary cross-references your writing against your saved sources. ChatGPT generates content but cannot verify it against your specific research.

Shareable collections. Build knowledge bases that colleagues or clients can browse and query. ChatGPT conversations are private by default.

1.4x more accurate on multi-document retrieval. In our benchmarking, Liminary scored 88.9% accuracy on multi-document questions versus 81.8% for GPT-5.4 with medium effort, and responded in 7.3 seconds versus 32 seconds.

Who should use what

ChatGPT is an excellent thinking partner for individual conversations, drafting, and analysis. Keep using it for what it does well.

Liminary is for the knowledge that should persist between those conversations: your research, your client context, your accumulated expertise. If you find yourself re-uploading the same documents to ChatGPT every week, re-explaining your client's situation every session, or wishing your AI remembered what you told it yesterday, Liminary eliminates that overhead.

Many professionals use both: ChatGPT for real-time reasoning, Liminary for persistent knowledge and ambient recall.
