Liminary

Liminary is an AI knowledge companion built specifically for consultants, strategists, researchers, and other professionals who make high-stakes recommendations grounded in real research. It combines a browser extension for one-click content capture with an AI layer that surfaces relevant saved knowledge proactively, fact-checks claims against sources, and helps create deliverables — all without using your data to train AI models. The team behind Liminary includes ex-Dropbox security, ML, and search engineers.

What It Is

Liminary sits at the intersection of knowledge management and AI-assisted research synthesis. Unlike general-purpose AI chat tools, it grounds every answer in sources you have explicitly saved — articles, reports, PDFs, AI chat transcripts, and videos — and traces each insight back to a specific source with one-click access. The core workflow runs from capture (via browser extension) through recall and fact-checking to deliverable creation and team collaboration.

Who It's Built For

The product is explicitly positioned for knowledge workers who bill for their perspective: management consultants, strategy consultants, market researchers, HR consultants, venture capital investors, executives, and think tank researchers. The homepage features testimonials from users in these roles describing how Liminary surfaces relevant work from past projects and connects insights across client engagements. The FAQ also addresses ethical academic research use cases.

How the Recall and Fact-Check Workflow Works

• Save: The browser extension captures web pages, PDFs, AI chat histories, and videos with a single click; users can annotate content with their own notes as they read.
• Recall: An AI layer proactively surfaces relevant saved material when you start a new project, including work from months-old engagements.
• Fact-check and gap detection: Available on higher tiers, this feature checks claims against saved and external sources and flags missing evidence.
• Watchlists: Users can set up monitoring for any client or project topic; Liminary tracks new information automatically.
• Create and collaborate: A writing assistant helps produce deliverables; projects can be shared with team members.

Accuracy and Privacy Claims

Liminary's own benchmark blog post claims the tool is "4x more accurate than ChatGPT at retrieving the right answer across internal and external sources," with a linked methodology page. Every answer distinguishes between user-saved data and external sources. The company states that client data is encrypted, siloed to the user's workspace, and never used to train AI models — a deliberate design choice for professionals handling confidential client information.

Deployment Model

Liminary is accessed via a web app at my.liminary.io combined with a browser extension available on both the Chrome Web Store and Firefox Add-ons store. The Chrome extension is rated 5 out of 5 stars on the Chrome Web Store according to the homepage. There is no desktop app or self-hosted option mentioned in the available sources.

Current Status

As of mid-2026, Liminary is actively publishing benchmark comparisons (including posts comparing performance against Claude Projects and Ask Gemini dated May 2026) and blog content, indicating ongoing product development. The about page still references "beta access," suggesting the product may still be in an early-access phase, though the pricing page offers a standard free trial and paid plans without explicit beta restrictions.
