## 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

## SpecsPlain

SpecsPlain is a small, focused browser extension built for developers who spend time inside specification documents. Standards like the ECMAScript (TC39) spec describe behavior through terse, formally worded algorithms that are precise but hard to read quickly. SpecsPlain inserts an Explain control directly into the specification page; clicking it sends the surrounding algorithm to Google's PaLM AI, which returns a plain-language walkthrough of the steps.

The extension is deliberately narrow in scope. At version 1.0.0 it targets the ECMAScript spec, and its stated goal is to make formal algorithm definitions easier to follow without leaving the page you are already reading. It is published by individual developer He-manth (h3manth.com) and installs as a standard Chrome extension that requires permission to read website content so it can process the spec text on screen.

SpecsPlain is free with no account or paid tier advertised. It is best treated as a convenience layer for spec reading rather than a full documentation platform: it does not host docs, track changes, or manage projects. Its listed Chrome Web Store privacy disclosure notes that it handles website content, and the developer declares that data is not sold to third parties or used for unrelated purposes.

**Pricing & Plans:** SpecsPlain is free. It is distributed as a no-cost Chrome extension with no advertised subscription or paid plan.

- **In-page Explain button:** Adds an Explain control to the specification document so you can request an explanation without switching tabs or tools.
- **PaLM AI powered explanations:** Uses Google's PaLM AI to convert formal spec algorithms into readable, step-by-step descriptions.
- **ECMAScript (TC39) focused:** Tuned for the ECMAScript specification, turning dense algorithmic text into something a developer can follow quickly.
- **Human-readable algorithm output:** Generates an explanation of what each step in an algorithm does, rather than restating the formal notation.
- **Minimal, lightweight install:** A small extension with a simple one-click workflow and no account setup required.

**Strengths:** Completely free with no sign-up required; Works directly inside the spec page you are already reading; Turns dense algorithmic notation into readable explanations; Very small, lightweight extension

**Limitations:** Limited to the ECMAScript (TC39) specification at version 1.0.0; Depends on Google's PaLM AI, so quality varies with the model output; No ratings yet and a very small user base, so community feedback is minimal
