Liminary
AI research memory with source-level accuracy for professionals.
Liminary earns our recommendation for consultants, analysts, and researchers who need bulletproof source provenance. Its proactive recall and fact-checking in Notion and Gmail reduce friction, and the recent Firefox support broadens reach. However, the free tier is tight and mobile/offline access is nonexistent. For broader platform support, consider Recall or Mem; for simpler memory, NotebookLM may suffice.

Skip Liminary if you need offline/mobile access, prefer manual note-taking, require on-premise deployment, or are budget-conscious and can't justify $29/month for Pro.
Going past 200 saved documents on the free Explorer tier forces an upgrade to Pro at $29/month, which is a significant jump for casual users.
Liminary's freemium model fits individual professionals wanting to test the workflow for free, but Pro at $29/month is comparable to other AI research tools like Recall or Mem (which often have similar pricing). For teams, Team at $50/user/month is pricier than some alternatives, but the shared knowledge base and integrations may justify it. Cheaper alternatives exist for simple note-taking (Notion, Obsidian), but they lack Liminary's source-level traceability.
In short
Liminary — AI research memory with source-level accuracy for professionals. Best for Management consultants creating client deliverables with multiple sources, Strategy professionals synthesizing research across engagements, Market researchers tracking industry trends and whitepapers. Free to start; paid plans from $29/mo.

About Liminary
Liminary is a browser extension (Chrome and Firefox) that acts as a persistent research memory for professionals who make high-stakes recommendations. It automatically captures content from web pages, PDFs, AI chats, YouTube, and email threads, then proactively surfaces relevant insights when you need them—without manual tagging. Designed for consultants, analysts, and researchers, it stores everything in a searchable knowledge base, with every insight tracing back to its original source. Key capabilities include one-click capture with annotation, proactive recall, a writing assistant with fact-checking and gap detection (now available in Notion), a live meeting assistant (Magnet) that pulls in relevant information during calls and saves summaries, Gmail drafting from chat, and watchlist monitoring for new information on clients or projects. Liminary claims 3.4X better retrieval accuracy than ChatGPT across internal and external sources, and supports collaborative workspaces (up to 10 people on Pro, 50 on Team). It integrates with Slack, Granola, and Claude via MCP. Data is encrypted, siloed per workspace, and never used to train AI models. The free Explorer tier is limited to 200 documents and 10 uploads per day, while Pro at $29/month unlocks unlimited sources, advanced recall, and unlimited meeting assistant usage. Liminary now also supports Firefox (added April 2026). Recent updates include Gmail drafting, Notion fact-checking, and a live meeting assistant. Compared to general-purpose AI tools like ChatGPT or Claude, Liminary is purpose-built for knowledge workers who need traceable, fact-checked deliverables, positioning itself as a research memory layer rather than a chatbot.
Behind the Verdict
Liminary is a browser extension that implements a research memory layer specifically for professionals who must produce fact-checked, source-backed deliverables. Unlike general AI assistants that answer from a black-box model, Liminary ties every insight to an original source, which is a decisive advantage when your reputation depends on accuracy. The tool's strength is its proactive recall: it surfaces relevant past research without you asking, which we found genuinely useful in multi-client consulting scenarios. The recent addition of Gmail drafting and Notion fact-checking means you can now draft and verify in the tools you already use. The Magnet meeting assistant is a thoughtful add-on that captures meeting context and pulls relevant knowledge in real time. However, Liminary is inherently a browser-extension experience—there's no mobile app or offline mode, so if you work across devices or need access without internet, this won't fit. The free Explorer plan is tight (200 documents, 10 uploads/day, 3 composer uses), and the Pro tier at $29/month may be hard to justify for casual users. Data privacy is a strong point: your data is encrypted, siloed per workspace, and never used to train AI models—important for client confidentiality. Overall, Liminary is excellent for knowledge workers who prioritize traceability, but it's not for everyone.

Where the pricing makes sense
The company stage and team size where Liminary's pricing actually pencils out — and where peers do it cheaper.
Liminary's freemium model fits individual professionals wanting to test the workflow for free, but Pro at $29/month is comparable to other AI research tools like Recall or Mem (which often have similar pricing). For teams, Team at $50/user/month is pricier than some alternatives, but the shared knowledge base and integrations may justify it. Cheaper alternatives exist for simple note-taking (Notion, Obsidian), but they lack Liminary's source-level traceability.
Setup time & first value
How long it actually takes to get something useful out of Liminary — broken out by persona, not the marketing-page minute.
For most users, getting value takes under 30 minutes: install the extension, save a few sources, and set up a watchlist. First proactive recall appears within hours of use. Meeting assistant (Magnet) setup is quick but requires granting mic access and linking your calendar. Notion fact-checking setup takes about 5 minutes to connect your workspace.
Switching to or from Liminary
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From NotebookLM: Export your sources as PDFs and upload them directly to Liminary; you'll gain source-level traceability and proactive recall that NotebookLM lacks.
- →From a manual folder of PDFs: Drag-and-drop upload your PDFs into Liminary and use the automatic organization and search to find insights faster.
- ↗To Notion: Export your saved notes or use the Notion integration to copy summaries; you'll lose proactive recall but gain full manual control.
- ↗To a general AI like ChatGPT: You can copy conversations and sources into ChatGPT, but you'll lose source provenance and proactive surfacing.

Featured Head-to-Head Comparisons
Liminary vs Praktika
If you're a consultant or researcher drowning in sources, Liminary's auto-capture, fact-checking, and meeting sidekick make it the clear choice.

These tools address completely different needs—choose based on whether your bottleneck is information retention or language fluency.
Liminary vs Surge Ai
Liminary is the right choice for individual professionals who need to manage and recall research without manual effort, especially if you use Chrome and want integration with Gmail, Notion, and meetings. Surge AI is built for enterprise AI teams that require expert human feedback to train and evaluate frontier models; it is not a tool for personal productivity. Choose Liminary for knowledge work, Surge AI for AI alignment and RLHF.
