## 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

## Perplexity

Perplexity is an AI-native answer engine and autonomous research platform designed to replace traditional keyword search and fragmented browser tab workflows. Instead of returning a ranked list of blue links, Perplexity interprets complex natural-language queries, crawls live web indexes, academic databases, financial filings, and social discussions in real time, and synthesizes direct, structured answers anchored by numbered inline citations. Beyond conversational search, the platform has evolved into a broader agentic ecosystem encompassing Perplexity Computer for autonomous multi-step tasks and the Comet AI browser assistant.

Under the hood, Perplexity orchestrates its proprietary web-grounded Sonar model family alongside frontier third-party reasoning models—allowing paid subscribers to route queries through Claude Opus 4 and Sonnet 4, OpenAI's o3-pro and GPT series, or Google's Gemini models, or run parallel evaluations via Model Council. Its Deep Research mode autonomously decomposes intricate questions, conducts dozens of iterative searches across hundreds of primary sources, and compiles exhaustive, exportable briefing reports in minutes. Users can also organize ongoing projects inside Perplexity Spaces, which fuse uploaded private documents (PDFs, CSVs, docs) with live web grounding and custom system instructions.

Perplexity serves an expansive audience ranging from students and journalists to equity analysts, legal researchers, and software engineers. Individual users can rely on the free tier for everyday fact-checking, step up to Perplexity Pro ($20/month) for daily deep research and model switching, or subscribe to Perplexity Max ($200/month) for uncapped high-compute agentic runs. Organizations adopt Enterprise Pro ($40/seat/month) and Enterprise Max ($325/seat/month) for SOC 2 compliance, zero data training guarantees, and internal knowledge connectors, while developers integrate real-time grounded citations into custom software via the Sonar REST API.

**Pricing & Plans:** Offers a permanent Free tier with unlimited Quick Searches, 3 Pro Searches per day, and 1 Deep Research query per month; Perplexity Pro costs $20/month ($200/year) and Perplexity Max costs $200/month ($2,000/year) for individuals. Team plans start at $40/seat/month ($400/seat/year) for Enterprise Pro and $325/seat/month for Enterprise Max, alongside usage-based Sonar API billing.

- **Deep Research Autonomous Reports:** Executes multi-step iterative web and document research across hundreds of sources, cross-checking facts and generating structured, citation-backed analytical reports that can be exported as PDFs or shared as interactive Perplexity Pages.
- **Multi-Model Routing & Model Council:** Lets Pro and Max subscribers switch dynamically between Perplexity's in-house Sonar models and top external models (including Claude 4, o3-pro, and Gemini) or compare multi-model reasoning outputs side by side.
- **Perplexity Spaces & Hybrid RAG:** Provides dedicated project workspaces where users upload local PDFs, spreadsheets, and text files, configure custom assistant instructions, and run queries that combine private document retrieval with live internet search.
- **Perplexity Computer & Comet Assistant:** Extends Perplexity from passive Q&A into agentic execution, turning high-level user requests into completed workflows, multi-tab browser actions, and automated data synthesis via the Comet ecosystem.
- **Sonar Web-Grounded Developer API:** Exposes Sonar, Sonar Pro, Sonar Reasoning Pro, and Sonar Deep Research over standard HTTP endpoints so developers can embed low-latency, live-cited web intelligence directly into third-party applications.

**Strengths:** Every generated statement links directly to numbered, verifiable web or document sources, drastically reducing ungrounded LLM hallucinations.; Deep Research mode delivers comprehensive, multi-page synthesis reports at a fraction of the time required for manual desk research.; Broad model optionality lets subscribers use Sonar, Claude, OpenAI, and Gemini models under a single $20/month subscription.; Focused search scopes (Academic, Finance, Web, Social) and Spaces allow clean separation between general browsing and domain-specific knowledge work.

**Limitations:** The Free tier is tightly restricted to 3 Pro Searches per day and just 1 Deep Research query per month with no manual model selection.; Power users requiring heavy agentic Computer runs or uncapped o3-pro/Opus-level research must jump from $20/month Pro to the steep $200/month Max tier.; Synthesized summaries can still inherit inaccuracies if underlying top-ranked web sources contain outdated or biased reporting.
