## 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

## Vizzy

Vizzy is a browser-based data visualization tool built around a simple idea: large language models are good at reasoning about data but poor at drawing it. Vizzy splits the job. You describe your data to an LLM, or hand it a raw export, and ask for a structured chart or map definition. Then you paste that JSON into Vizzy, which takes care of rendering it as a real, interactive visualization.

Because the output is declarative JSON rather than a specific chart type, the same approach covers bar charts, line charts, scatter plots, tables and geographic maps over a base layer. Vizzy can also ingest the underlying data directly in JSON, CSV or XML, so you are not limited to hand-crafted specs; uploading a dataset and a matching spec is often the fastest path from raw numbers to something you can look at.

The project markets itself as open source and rapid, targeting people who want a quick visual answer rather than a full dashboard build. Its homepage ships with a set of ready-made demo datasets — scripts from the TV show The Office, changes in same-sex marriage legislation across U.S. states over time, U.S. state obesity rates with shape geometry, CDC cause-of-death coverage versus news mentions, and a U.S. national parks dataset with geographic and activity detail. Those examples double as templates showing what kinds of data the tool handles well.

**Pricing & Plans:** Vizzy is presented as an open-source project with no visible paid plans, sign-up gate or pricing page. Treat it as a free, self-hostable tool rather than a commercial subscription product.

- **Render LLM-authored chart specs:** Paste JSON generated by ChatGPT, Claude or another LLM and Vizzy draws the corresponding chart, graph, map or table.
- **Multi-format data input:** Load data as JSON, CSV or XML, so exports from databases, spreadsheets and APIs can all feed the same viewer.
- **Charts, graphs and maps:** Go beyond bar and line charts with geographic map rendering for location-based datasets.
- **Sample datasets included:** Built-in examples such as U.S. national parks, state obesity rates, same-sex marriage legislation timelines and CDC causes of death let you try the tool instantly.
- **Data storytelling focus:** The project is aimed at exploring unusual or journalistic datasets quickly rather than being a full BI platform.

**Strengths:** No account or installation needed to start visualizing; Splits work sensibly: LLM for reasoning, Vizzy for rendering; Supports JSON, CSV and XML inputs plus maps, not just basic charts; Open source, so it can be self-hosted and inspected

**Limitations:** A small, minimally maintained project with limited documentation; No built-in AI chat — you still need an external LLM to generate specs; Not a substitute for a full BI or dashboarding platform
