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) ## PERSYS PERSYS is dedicated hardware rather than an app or a cloud subscription. It is positioned as a complement to your laptop and phone, not a replacement: a box that sits at home and acts like your own personal cloud, holding files and running AI inference locally. Because inference happens on the device, conversations with the assistant are not sent to external servers, and the system stays usable without an internet connection. The software stack is open source for transparency, and the device ships with AI-native applications built for the hardware: Private Chat, Deep Search, Smart Notes, Document Library, Private Gallery and Media Player. The specification is deliberately simple. Two storage tiers are offered, 1 TB and 2 TB, with 8 GB or 16 GB of memory respectively, dual WiFi and 27 W power draw in a matte white enclosure with a stand included. PERSYS is sold directly by AdulisAI, Inc. with support documentation, a GitHub presence and community links. **Pricing & Plans:** Hardware purchase, no subscription mentioned. The 1 TB model is listed at $300 and the 2 TB model at $330, with the stand included. Prices are as shown on the vendor site and may change. - **On-device AI inference:** Models run locally, so chats and prompts are processed on the device rather than in a remote data centre. - **Works without internet:** Chat, search, notes and the document library remain accessible with no connection, making the device useful offline. - **Large local storage:** Choose 1 TB or 2 TB of solid-state storage for photos, videos and documents, all kept inside the device. - **AI-native apps:** Private Chat, Deep Search, Smart Notes, Document Library, Private Gallery and Media Player are built for the hardware from the ground up. - **Open source software:** The stack is published openly so users and researchers can verify what the device actually does with their data. **Strengths:** Conversations and files never leave your hardware; Fully usable offline, including AI chat and search; Open source software aids transparency and trust; Straightforward pricing with no subscription required **Limitations:** On-device models are typically less capable than the largest cloud models; You buy dedicated hardware upfront, a bigger commitment than an app; Documentation pages were not reachable at the time of the check [Profile (Markdown)](https://openaitools.app/tool/persys.md) ## Frequently Asked Questions ### How do Glean and PERSYS compare in monthly traffic?
