## Casper AI

Casper AI is a browser extension aimed at people who spend their day absorbing information: analysts, strategists, policy watchers and business developers. Once installed in Chrome, it works on the page or PDF you are already looking at, using AI models to condense long articles, reports and papers into short summaries you can actually finish. The stated goal is to remove the reading bottleneck before a meeting, an exam or an investment decision.

The extension goes a step beyond plain summarization. It is designed to help you highlight the most important new insights, pull structure out of dense documents and turn what you learned into short notes you can share with teammates and stakeholders. Because it lives in the toolbar, the workflow is: open the source, summarize, and send the takeaway, without moving content into a separate tool.

Casper AI is distributed through the Chrome Web Store by its developer and offers in-app purchases on top of its free tier. It has a sizeable user base and a strong average rating, and it explicitly targets non-technical users who want AI assistance without building a prompt workflow themselves. Expect it to save time on reading-heavy tasks rather than to replace expert judgement on the documents themselves.

**Pricing & Plans:** Casper AI is listed as freemium in the Chrome Web Store with in-app purchases available alongside the free extension.

- **Web page summarization:** Condense long articles and pages into short summaries directly from the browser, without copying text into another app.
- **PDF summarization:** Work through reports and papers in PDF form and pull out the central points rather than reading cover to cover.
- **Insight highlighting:** Surfaces the most important new information in a document so you can focus attention where it matters.
- **Shareable notes:** Turn what you have read into concise notes you can forward to colleagues and stakeholders.
- **Chrome toolbar workflow:** Runs as a lightweight extension inside Chrome, so summarizing is one action away on any page you visit.

**Strengths:** Summarizes both web pages and PDFs from the same browser extension; 10,000+ users and a strong average rating in the Chrome Web Store; Designed for non-technical professionals, with no prompt engineering required; Share-oriented output makes it easy to brief teammates

**Limitations:** Requires Chrome, since it is delivered only as a browser extension; Summaries are only as good as the source document, so critical review still matters; Some capability sits behind in-app purchases rather than the free tier

## 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
