## 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

## PeerReview

PeerReview is a minimal Chrome extension whose entire purpose is captured by its tagline: summarize any text with just a click. Highlight a paragraph, invoke the extension, and it returns a condensed version of the passage without redirecting you to a separate summarization app or web service.

The extension is built on Gemini's Prompt API and Summarizer API, the browser-native interfaces Chrome exposes for on-device language model work. That choice makes PeerReview a lightweight layer over capabilities Chrome already provides rather than a standalone AI service with its own servers and accounts. It is published as an open-source project, and its store listing explicitly invites contributors.

PeerReview is at an early stage: version 0.0.1, published in December 2024, with a small install base. The developer has disclosed that it does not collect or use user data, and the package is only a few kilobytes. Treat it as a steerable open-source utility for students, translators, developers and heavy readers who already run a compatible Chrome build and want faster reading rather than a full productivity suite.

**Pricing & Plans:** Free. The Chrome Web Store listing shows no paid tiers; PeerReview is distributed free of charge as an open-source project.

- **One-click summarization:** Select a passage and click once to replace hunting through menus with an immediate summary.
- **Gemini Prompt & Summarizer APIs:** Uses Gemini's Prompt API and Summarizer API, Chrome's built-in on-device AI interfaces, rather than a custom backend.
- **Works on any highlighted text:** Skims pages, drafts and pasted text and returns the gist without taking you out of the tab.
- **Open source:** A public open-source project that welcomes outside contributions and code review.
- **Privacy-friendly by default:** Small package (about 6.7 KB) with virtually no interface overhead, and the developer states no data collection.

**Strengths:** One-click workflow keeps you inside the page you are reading; Built on Gemini's browser-native APIs, so no external accounts or API keys to manage; Open source, so the behaviour is auditable and improvable by contributors; Developer declares that no user data is collected or used

**Limitations:** Very early proof-of-concept (v0.0.1) with no visible release history or roadmap; Depends on on-device Gemini APIs, so behaviour varies by Chrome version and hardware; No accounts, sync or team features, and effectively no vendor support
