## Hex

Hex starts from a simple observation: dashboards tell you what happened, but they rarely answer the follow-up question. Its core is the Hex Agent, a conversational interface that plans a query, reasons over your organisation's context and returns an answer with the charts, tables and code that produced it. Because every answer is grounded in a semantic model and the underlying warehouse tables, users can inspect the SQL, check assumptions and trust the number before acting on it. The agent is reachable from the web workspace, from Slack, and from developer tools such as Claude and Codex via CLI and integrations.
Underneath the conversational layer sits a genuine notebook and app-building environment. Analysts write SQL, Python and R in the same project, chain cells into reproducible pipelines, and then turn selected cells into polished, parameterised data apps and dashboards that stakeholders can interact with. Hex 4.0 pushes this further with generative dashboards, AI app building and a Context Engine that keeps the company's definitions, metrics and semantics in one place. A Context Studio surfaces where the agent lacked grounding, and an Evals framework lets teams run graded test suites against the agent to measure accuracy over time.
That governance angle is what separates Hex from raw chat-with-your-data tools. Instead of an unsearchable answer in a side panel, you get a shareable, versionable artefact with lineage, plus a feedback loop that compounds context quality. It is used by data teams at a wide range of companies for self-serve exploration, executive reporting, embedded dashboards and operational analytics, with free, paid and enterprise tiers covering individuals through to regulated organisations needing SSO and advanced security.

**Pricing & Plans:** Freemium with a free tier to get started, paid plans for growing teams, and enterprise pricing (quoted on request) that adds governance, SSO and advanced security. A free trial is available for paid tiers.

- **Conversational Hex Agent:** Ask a question in plain language and get a reasoned answer with the SQL, charts and tables behind it, available in the Hex workspace, in Slack and from developer tools.
- **Notebooks and app builder:** Write SQL, Python and R side by side in one project, then turn cells into interactive, parameterised data apps and dashboards without a separate BI authoring tool.
- **Context Engine and Context Studio:** Centralise metrics, semantics and corporate definitions so answers stay consistent, and see exactly where the agent lacked grounding so you can fix it.
- **Evals for agent accuracy:** Run graded, rubric-based test suites against the agent to measure answer quality and catch regressions as your data and context evolve.
- **Generative dashboards and governance:** Produce dashboards from natural language, embed them where teams work, and manage access with enterprise-grade permissions and security.

**Strengths:** Unifies exploration, notebooks, dashboards and app building so teams stop paying for four overlapping tools; Answers are grounded in a semantic model and warehouse tables, and stay inspectable rather than opaque; Slack, CLI and developer-tool integrations meet users where they already work; Context Studio and Evals turn context quality into something measurable and improvable

**Limitations:** The full value depends on having a reasonably well-modelled warehouse, so it is heavier to adopt than a simple chat tool; The notebook-plus-agent surface is feature-rich enough to need onboarding for non-technical users; Governance and advanced security features are reserved for higher-priced and enterprise plans

## Lang (by Capacity)

Lang.ai started life as a standalone conversation intelligence product that helped teams mine unstructured customer conversations for patterns, escalation drivers and revenue signals. It has since been folded into Capacity, an AI-powered support automation platform, and the lang.ai domain now redirects to capacity.com/lang. Existing users and new buyers alike access Lang's capabilities as a module of the wider Capacity stack rather than as a separate subscription.

Functionally, Lang turns customer conversations into decision-ready intelligence. You ask questions about interactions in plain English and the Assistant answers using data drawn from voice, chat, SMS and helpdesk systems, giving a 360-degree view of ticket metadata, workflow performance and bot usage. Dashboards can be assembled from live interaction data and shared with stakeholders on a recurring schedule, so reporting stops being a manual chore. As part of Capacity, these analytics feed Auto QA, CSAT scoring, interaction summaries and agent coaching.

Capacity itself is a substantial platform: 20,000+ customers, 1.5 million users and more than 36 billion automated interactions, founded in 2017 in St. Louis. Lang's conversation intelligence is positioned as the analytics brain inside that ecosystem, complementing AI agents, real-time agent assist and outbound campaigns. Pricing is not published and is quoted per engagement through a demo request.

**Pricing & Plans:** Paid via custom quote. Lang's capabilities are now delivered as part of the Capacity platform, priced per engagement through a demo request rather than published tiers.

- **Natural-language insight queries:** Ask questions about customer interactions in plain English and get answers instantly, without manual reporting or complex analysis.
- **Executive-ready dashboards:** Turn live customer interaction data into presentation-ready dashboards and share them with stakeholders on a recurring schedule.
- **Unified data intelligence:** Unlike siloed tools, the Assistant sits on top of your voice, chat, SMS and helpdesk ecosystem for a 360-degree view of ticket metadata, workflow performance and bot usage.
- **Interaction intelligence:** Uncover trends, escalation drivers and performance insights across every customer conversation, at scale.
- **Part of the Capacity platform:** As part of Capacity, Lang's analytics feed Auto QA, CSAT scoring, interaction summaries and agent coaching.

**Strengths:** Plain-English querying removes reliance on analysts and manual reporting; Draws on voice, chat, SMS and helpdesk data for a genuine 360-degree view; Automatic dashboards suit recurring executive reporting; Backed by Capacity's 20,000+ customer platform and 250+ integrations

**Limitations:** Lang AI is no longer sold as a standalone product; it is now part of Capacity's broader platform; Pricing is quote-based and not published, which slows evaluation; Deepest value is realised by teams already running Capacity or similar helpdesk stacks; Rolling out conversation intelligence across all channels takes setup and data hygiene work
