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 [Profile (Markdown)](https://openaitools.app/tool/glean.md) ## Rerun Rerun is an open-source SDK and visualizer built for multi-rate, multimodal data, and it markets itself as the data layer for physical AI. Engineers use it to log sensor streams, computer-vision outputs, 3D transforms, and time-series metrics from the first recording through to large-scale review. Because it is a flexible framework rather than a locked platform, teams can extend the viewer with their own views and tools at each stage of the pipeline. The SDK ships with Python, Rust, and C++ APIs, so it fits into existing robotics and perception stacks without a rewrite. Data is stored as column-chunks in rrd files, which supports full dataframe or SQL queries over any recording, down into the columns, time ranges, and values inside it rather than only metadata. Beyond the free tooling, Rerun offers Rerun Hub, a production backend that catalogs recordings, indexes byte ranges, and turns object stores into a queryable, streamable foundation. Hub supports running transforms on the edge or close to the data and streaming datasets directly to GPUs for training without an export step. **Pricing & Plans:** The Rerun SDK and viewer are open source and free to use. Rerun also offers Rerun Hub, a production backend, whose pricing is arranged separately with the team. Check the Rerun website and GitHub repository for current terms. - **Multimodal data visualization:** Log, store, and view images, point clouds, 3D transforms, and time series together in one viewer. - **Open-source logging SDK:** Record multi-rate, multimodal data as column-chunks in rrd files, or convert from other formats. - **Query and transform:** Run full dataframe or SQL queries over robotics data, down into columns, time ranges, and values. - **Edge and stream transforms:** Add derived columns and evolve schemas without breaking history, on the edge or near the data. - **Rerun Hub backend:** A hosted backend with catalog, byte-range indexing, and retrieval that turns object stores into a queryable dataset. **Strengths:** Open-source core with permissive use across research and production; Handles multimodal and multi-rate data in one viewer; APIs for Python, Rust, and C++; Query and transform data without an export step **Limitations:** Requires coding in Rust, Python, or C++ to get full value; The hosted Rerun Hub backend is a newer, additional product beyond the free SDK; Visualization work is aimed at engineering teams, not general business users; Advanced production features assume existing logging pipelines [Profile (Markdown)](https://openaitools.app/tool/rerun.md) ## Frequently Asked Questions ### How do Glean and Rerun compare in monthly traffic?
