## Glean

Glean addresses a problem most enterprises hit after their first wave of AI adoption: models are powerful but isolated from the context of the business. The platform builds an enterprise context layer by indexing and understanding content across the tools a company already runs on, then uses that grounding to improve both answer quality and efficiency. Because fewer irrelevant tokens need to be sent to a model, the same question costs less to serve.

The product surface spans four areas: enterprise search, an AI assistant for everyday work, an agent platform for automating long-running processes, and Glean Protect for security and governance. Administrators also get model routing and an AI gateway, letting them decide which models handle which requests without rebuilding integrations. Everything inherits the access permissions of the source systems, so answers stay within each employee's existing rights.

Glean serves large organisations across finance, healthcare, retail, technology, and government, with published customers including Booking.com, Zillow, and Ericsson. It holds SOC 2 Type II, ISO 27001, ISO 42001, HIPAA, GDPR, and TX-RAMP Level 2 attestations, and reports 275+ connectors, 40+ supported language models, and 99.9%+ uptime on core services.

**Pricing & Plans:** Contact for pricing. Glean is licensed to organisations based on seats, connectors, and deployment scope, and is evaluated through a demo rather than self-serve purchase.

- **Permission-aware enterprise search:** Ask a question in plain language and get a cited answer assembled from documents, tickets, wikis, and messages across every connected system, with permissions respected.
- **Agent builder and orchestration:** Reusable agents handle multi-step workflows such as onboarding, account research, or incident follow-up by orchestrating actions across business apps.
- **Model routing and AI gateway:** Glean automatically picks and routes requests to the right model and reasoning level, giving teams access to 40+ LLMs through a single governed gateway.
- **Grounded content and analysis:** Draft on-brand documents, summarise meetings, analyse data, and create content grounded in company context rather than generic model knowledge.
- **Governance and observability:** Administrators get usage controls, spend visibility, audit logging, and compliance-ready governance for every AI interaction.

**Strengths:** Answers cite source systems and inherit their permissions, which removes the main blocker to enterprise-wide rollout; One platform covers search, assistant, and agents instead of three separate vendors; Model routing and token efficiency directly reduce the cost per AI query at scale; 275+ pre-built connectors shorten integration work considerably

**Limitations:** Enterprise pricing is quote-based, so budget planning requires a sales conversation; Full value depends on connecting many internal data sources, which takes IT effort; Smallest teams may find the platform more than they need

## Review Express

Review Express is a Chrome extension built around one of the most repetitive tasks in research: getting through a long paper fast enough to decide whether it matters. Instead of a general-purpose summariser, it ships with pre-engineered prompts aimed specifically at scientific papers, and lets you choose a summary mode that matches why you are reading - a broad overview, the key findings, or something in between.

The published version works on highlighted text. You select a passage on a journal site or any web page, trigger the extension, and get a summary in your chosen mode. You can also ask direct questions about the selection, which is handy when you need to check whether a paper actually supports a specific claim before citing it. The developer notes that the extension consults the surrounding article text as well as your selection, so summaries are more contextual than the highlight alone would suggest.

Review Express is a small, early-stage project - the public version is 0.1.x and the developer describes more features as forthcoming. It is currently English-only in the interface, and it is an independent tool rather than something published by a journal, university, or AI vendor. For a research workflow where you read many abstracts and papers in a day, that narrow focus on scientific summarization is the main reason to try it.

**Pricing & Plans:** Freemium. The extension is free to add from the Chrome Web Store, and the developer also operates a web app at review-express-v1.vercel.app that offers a download and a sign-in, suggesting account-based paid or expanded usage. No specific plan prices or free-tier limits were published on the pages checked, so exact quotas should be confirmed in the app itself.

- **Prompts built for scientific papers:** A pre-engineered prompt library tuned for journal articles, so summaries focus on the parts researchers actually need rather than generic gist.
- **Multiple summary modes:** Pick from different summary modes depending on whether you want an overview, the key findings, or a specific angle on the passage.
- **Ask questions about the selected text:** Go beyond summarizing by asking targeted questions about the text you have selected, useful for checking whether a paper supports a claim.
- **Journal articles and general web pages:** Works on journal sites as well as ordinary web pages, so long reports, documentation, and news articles are fair game.
- **In-browser workflow:** Runs inside Chrome on the page you are already reading, with no separate app or dashboard to switch to.

**Strengths:** Prompts are purpose-built for scientific papers instead of generic summarization; Several summary modes let you match the output to your reading goal; Question answering on selected text helps verify claims before citing; Works on journal sites and ordinary web pages alike

**Limitations:** Currently only summarises text you highlight, not entire documents in one pass; English-only interface; Early-stage release with a small user base and further features still promised
