## 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

## OpenTag

OpenTag is an AI coworker built for team chat, primarily Slack, with Microsoft Teams support announced as coming soon. Instead of sending you to yet another dashboard, you mention the agent in a thread and the result comes back to the same conversation. It can research and answer questions from company knowledge, Slack history, meeting notes, Notion, Google Drive and the open web, then go further and write copy, briefs, summaries and reports, read Linear issues and GitHub repositories, and analyse product data from PostHog, Stripe and ad platforms.

Two design choices set it apart. First, it is model-agnostic: rather than binding you to one vendor, OpenTag routes each request to whichever of 40+ models is the best fit using reliability, speed, capability and cost as criteria, so routine work does not burn frontier-model tokens. Second, it runs tasks as sandboxed cloud agents scoped to the tools a task actually needs, with each request limited to the permissions of the person who asked, so teammates never have to share credentials and private channels stay private. Actions with meaningful consequences are surfaced for approval before anything is changed.

Over time the tool also builds a living company wiki from conversations and connected sources, updating pages when decisions change and keeping institutional knowledge available even after the person who held it leaves. Recurring requests can be promoted into automations that run on a schedule or fire on events such as a new message, meeting or email. OpenTag offers a free starting point and paid plans, with pricing available on its site and a demo available for larger rollouts.

**Pricing & Plans:** Free to get started via app.tryopentag.com sign-up; paid plans and a demo option are listed on the OpenTag pricing page.

- **Slack-native AI coworker:** Mention OpenTag in a thread and the answer or completed work returns to that same channel, with no separate app to babysit.
- **40+ model routing:** Each request is routed to the most suitable model from families such as GPT, Claude, Gemini, DeepSeek, Grok, Kimi, Qwen, Llama and Mistral, targeting large cost savings versus sending everything to a frontier model.
- **50+ tool integrations:** Connect Slack, Google Workspace, Notion, Confluence, Linear, ClickUp, GitHub, HubSpot, Stripe, PostHog, Fireflies, Granola and dozens more so work moves from question to action.
- **Approval-gated actions:** Consequential steps are presented for review, and you can approve, adjust or decline before anything in a connected system changes.
- **Living company wiki:** Conversations and connected sources are distilled into an organized, source-linked wiki that updates when decisions change.

**Strengths:** Works inside Slack rather than forcing a new interface; Model-agnostic routing can cut cost per task versus a single frontier model; Permission-scoped agents and approval gates keep sensitive actions in human hands; Broad integration catalogue covering engineering, sales, finance and analytics tools

**Limitations:** Core experience is Slack today; Microsoft Teams support is not yet available; Value depends on connecting your tools and knowledge sources properly; The 70% cost-saving figure is a routing target rather than a guaranteed customer average
