## 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

## ReadTheory

ReadTheory began as a free adaptive reading comprehension program and has grown into a full practice and assessment platform used by teachers, schools, and districts worldwide. Students read short passages and answer comprehension questions at their current level; the system adjusts difficulty after each answer, so a reader is always working just beyond their comfort zone rather than being stuck on content that is far too easy or far too hard. Teachers see live feedback data and can identify exactly where comprehension breaks down.

Reporting is one of its strongest draws. A single dashboard shows growth, mastery, and gaps at the student, class, school, and district level, expressed in Lexile measures, grade levels, and ELA standards. Beginning, middle, and end-of-year benchmark assessments are included at no extra cost, and schools report meaningful gains on state assessments after consistent use.

The content side combines a large human-written library of fiction and nonfiction with an AI worksheet builder that generates passages and questions on any topic in seconds. ReadTheory also keeps a strong offline component: passages, quizzes, graphic organizers, and worksheets can all be printed for small groups, substitute teaching, or any lesson where screens are not the answer. Onboarding is lightweight, with classes set up in about five minutes and no lengthy training required, and the platform is designed around student privacy and FERPA compliance.

**Pricing & Plans:** ReadTheory is free to start for individual teachers, students, and parents, and the company describes its core practice as free. Paid plans exist for schools and districts that need school-wide and district-level reporting, administrative tools, and broader support; specific pricing tiers should be confirmed with ReadTheory directly or through their sales team.

- **Adaptive leveled practice:** A quick benchmark assessment finds each student's true reading level in around 14 minutes, then the difficulty adjusts continuously as they practice.
- **AI worksheet builder and text library:** Generate reading passages and questions on any topic in seconds, or choose from thousands of standards-aligned fiction and nonfiction texts written by real authors.
- **Progress and standards reporting:** One dashboard shows growth, mastery, and gaps across every student, class, school, and district, reporting in Lexile, grade, and ELA standard terms.
- **Printable resources:** Passages, quizzes, graphic organizers, and worksheets are available to print for small groups, substitute days, and screen-free lessons.
- **Built-in benchmarks and privacy:** Beginning, middle, and end-of-year benchmarks are included at no extra cost, and the platform is FERPA compliant with transparent data practices.

**Strengths:** Free core adaptive reading practice for teachers and students; Automatic grading and instant feedback save substantial teacher time; Reporting covers students, classes, schools, and districts in Lexile, grade, and ELA standard terms; Built-in BOY, MOY, and EOY benchmarks at no extra cost
