## Liminary

Liminary targets a familiar professional failure mode: you do the research, then spend the first hour of the next project re-finding it. The tool acts as a persistent memory layer. Articles, reports, PDFs, videos and AI chats are saved with one click while you browse, and you can add your own notes and context as you read, so the stored knowledge reflects your thinking and not just the source text.

Retrieval is the differentiating part. Rather than waiting for you to search, Liminary proactively surfaces what is relevant while you write, and it now includes Magnet, a meeting sidekick that pulls in the right material in real time. Answers are grounded in your saved sources, with every insight traceable to a citation and every source one click away. Fact-checking and gap detection run against your own material rather than the open internet, so you can verify claims and spot missing pieces before someone else does.

Security is positioned as a core feature rather than an afterthought: data is encrypted, siloed to your workspace, and never used to train AI models, with the team crediting ex-Dropbox security, ML and search engineers. The product is aimed at consultants, researchers, analysts and small teams whose recommendations carry professional risk if the underlying facts are wrong.

Practicalities: Liminary ships as browser extensions for Chrome and Firefox with a rated 5-out-of-5 presence on the Chrome Web Store, and the vendor publishes benchmark posts on long-term memory evaluation. Pricing structure beyond a free download is presented on the site; check there for current plan tiers.

**Pricing & Plans:** Free download available to get started. Subscription tiers for professional and small-team use are listed on the Liminary site. Check the official pricing page for current plan details, since published tiers may change.

- **One-click saving anywhere:** Capture web pages, PDFs, videos, reports and LLM chats while you browse, then annotate them with your own notes and context.
- **Proactive recall:** Instead of waiting for a search, Liminary surfaces the relevant saved material while you write and inside meetings.
- **Magnet meeting sidekick:** A meeting companion that pulls in the right information at the right moment, then saves the summary, full transcript and your notes for later recall.
- **Sourced, traceable answers:** Every answer points back to where it came from, internal or external, so you can verify claims rather than trust a black box.
- **Fact check and gap detection:** Validate claims against your own saved sources and find what is missing in a draft, including directly inside Notion.

**Strengths:** Proactive recall means relevant knowledge finds you instead of requiring a search; Answers stay traceable to saved sources, which suits high-stakes professional work; Captures many source types in one place: pages, PDFs, videos and AI chats; Explicit privacy stance: encrypted, siloed per workspace and never used for model training

**Limitations:** Value depends on you actually saving sources, so the habit has to be built first; Overlaps with note tools like Notion, which can mean deciding where knowledge should live; Full plan structure is not fully clear from the landing page alone, so pricing needs checking

## SuperMemory

Supermemory is a memory and continual-learning layer built for AI agents and applications. Its premise is that raw model intelligence is no longer the bottleneck: models are highly capable but do not learn from live interaction on their own. Supermemory closes that gap by owning the infrastructure for storing what a system has learned and bringing it back to the model at the right moment.

Architecturally, raw data such as chats, URLs and structured content enters Supermemory, where a purpose-built learner model extracts, merges, infers and forgets information. The resulting learnings are stored in a vector-graph database with an understanding of entities, sources and time. When an agent makes a request, the most relevant memories are injected back into the model's context via hooks, rather than relying on embeddings or stuffing whole histories into the prompt.

Because the memory sits outside any single model provider, it travels across models and tool harnesses and is exposed programmatically. Official access is offered through an API, plugins and MCP, so it can be wired into common agent and coding environments. The company targets both individual developers and large organizations, reporting production usage at high scale and offering self-hosted and air-gapped deployments for teams with strict data-residency or compliance needs.

**Pricing & Plans:** Free plan gives $0/month with $5 of credits renewed monthly. Pro is $19/month ($20 credits), Max is $100/month ($130 credits), and Scale is $399/month ($600 credits) for production teams with advanced PDF extraction and self-hosting. Enterprise is custom with air-gapped deployment, SOC 2, HIPAA BAA and SLA. Credits draw from all meters at the same rates, and unchanged content is not re-billed.

- **Continual-learning memory engine:** A dedicated learner model extracts, merges, infers and forgets facts, storing each learning in a vector-graph database that understands entities, sources and time.
- **Real-time context injection:** Learnings are injected into the model's context in real time via hooks, so agents recall relevant information without stuffing full histories into the prompt.
- **Any model, any harness:** Memory lives outside any single model provider, so it carries across models and harnesses and is delivered through the API, plugins and MCP.
- **Deduplicated, usage-based billing:** Mandatory memory is only billed once: repeated or unchanged content is not charged again, and the same rates apply on every plan.
- **Enterprise security and deployment:** Air-gapped self-hosting, SOC 2 Type II certification, HIPAA BAA on higher tiers and GDPR compliance, with custom contracts and DPAs available.

**Strengths:** Purpose-built memory model handles extraction, merging, inference and forgetting automatically; Works with any model or harness through API, plugins and MCP, avoiding provider lock-in; Strong benchmark and production claims, including low-latency recall tuned for agent loops; Real enterprise options: SOC 2 Type II, HIPAA BAA, GDPR, self-hosting and air-gapped deployment

**Limitations:** The primary interface is developer-oriented (API, MCP, plugins), so non-technical users have a steeper learning curve; Pricing is credit-based, which makes it hard to predict spend without modeling your own ingestion and query volumes; Advanced PDF extraction and self-hosting are reserved for the higher-priced Scale and Enterprise tiers
