## Glasp

Glasp started from a simple observation: most people highlight things they never look at again. Instead of trapping highlights inside one app, Glasp makes them social. Install the extension, highlight a paragraph on any site or a line in a YouTube transcript, and it lands in your Glasp profile where you can add notes and tags. Because highlights are public by default unless you make them private, a feed of what like-minded people are reading and marking emerges — you can follow other users, see what resonates, and discover sources you would not have found on your own.

Your library becomes the raw material for AI features. Glasp can summarize a long article, a PDF or a YouTube video so you can decide whether it deserves reading, and it can organize what you have already saved into themes. The standout feature is the AI clone: by training on your own accumulated highlights and notes, it produces something that answers in the shape of your interests and reading history. There is also a digital-legacy angle, letting you hand your accumulated knowledge to someone else.

Glasp is free to start, with paid tiers for heavier use and greater AI capacity. Its real niche is learners, researchers, students and content curators who treat annotation as a public, collaborative practice rather than a private bookmark folder — and who want their saved material to do work for them later instead of gathering dust.

**Pricing & Plans:** Freemium. A free tier covers the core highlighting, saving and sharing features with limited AI usage; paid plans add higher AI limits and additional capacity. Check glasp.co for current tier pricing, as it is not published in our listing data.

- **Web and YouTube highlighting:** Mark up passages on any website or lines in a YouTube transcript from a browser extension, then keep them in one searchable library.
- **Social learning feed:** Highlights are shared publicly by default, so you can follow other users, react to their picks and discover sources through people with similar interests.
- **AI summarization:** Generate summaries of long articles, PDFs and YouTube videos to judge relevance fast and to digest what you have already saved.
- **Your own AI clone:** Trained on your accumulated highlights and notes, the AI clone answers in the shape of your reading history and areas of interest.
- **Notes, tags and Kindle import:** Add your own commentary and tags to every highlight, and bring in Kindle highlights so your reading lives in one place.

**Strengths:** Turns throwaway highlighting into a genuinely reusable, searchable library; The social feed surfaces sources through people rather than an opaque algorithm; AI summarization and the AI clone are built on your own saved material, not generic content; Works across web pages, YouTube, PDFs and Kindle imports in one place

**Limitations:** Public-by-default sharing is not for everyone; private lives behind a toggle you have to remember; The AI clone only becomes useful after you have accumulated a real body of highlights; Free-tier AI usage is limited, so heavy summarization pushes you to a paid plan

## 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
