The agent-native platform to shape better buildings

Any building. Every discipline. One shared model.

tangram is purpose-built for architects and engineers.

One shared building model connects design, engineering analysis, code checks and documentation, and works with the tools you already use.

You describe or draw your intent. AI agents take on the repetitive work and run deterministic engineering tools: the numbers come from the tools, never from the AI. Actions are traceable, results are auditable, and you stay in control.

Teams get instant feedback on structure, quantities and code checks, with cost and carbon next, so they can design better, more sustainable buildings.

From a plot to a real building

In a fraction of the time.

Capabilities

Design and engineering, on the same model.

The studies, discipline by discipline: what’s live today, and what’s coming. No vaporware, every live capability is something you can use now. We build on the French regulatory framework first, with the rest of Europe following fast on the shared Eurocode base, and other regions in preparation.

Architects

Keep your design intent, and iterate faster.

Every discipline works on your model, so ideas survive every exchange and each change carries through to the sheets.

  • Agentic modeling and documentation

    Live

    Sketch or describe it, and agents model the building with you, every element yours to edit by hand; plans, sections, elevations, schedules and sheets are drawn from the model. IFC in and out, PDF out.

  • Cost and carbon

    Coming

    Cost and carbon from the model’s quantities as the design moves, to compare options while they are still open.

  • Spatial design and compliance

    Coming

    Functional layouts generated with you, hand in hand with the fire safety and accessibility checks.

  • 3D rendering

    Roadmap

    Rendered views of the project, straight from the model.

Engineers

More engineering. Less repetition.

Let AI agents handle repetitive modeling and analysis tasks, so you can focus on the engineering decisions that matter.

  • Agentic modeling and documentation

    Live

    Agents model the structure with you, and the analytical model follows the building, supports and loads kept; general arrangement drawings, member schedules and the calculation note are drawn from the model. IFC in and out, PDF out.

  • Cost and carbon

    Coming

    Cost and carbon of the structure from the quantities of every member, to compare schemes, sections and materials.

  • Structure

    Partly live

    Load takedown, steel to Eurocode 3, concrete to Eurocode 2, partial, with the rest of structural engineering following.

  • Thermal, MEP, fluids, geotechnical

    Roadmap

    Each study on the same model as the structure.

Features

Built around the way you work.

You hold the pen.

  • Draw it yourself, or ask an agent

    Every action can be taken by hand or by an agent, on real building objects. AI never locks you out, it extends what you can do.

  • AI proposes. You decide.

    You drive, agents propose and act, every number is measured on the model, never written by the AI, and every step can be undone.

  • Start from a sketch or a sentence

    Model it yourself, or just describe it, a sketch, a file, whatever you have. Agents do the clicking; you check, correct, and decide.

Run it your way.

  • In your browser, nothing to install

    Runs locally in your browser and renders on your GPU, so there’s no lag and no install. Your plans, sections and quantities redraw automatically as the model changes.

  • Your projects, where you choose

    Your projects stay yours. The engine can run locally, nothing is forced onto our servers, and a shared model can live on your own infrastructure.

  • With the AI you already use

    LLM-agnostic by design. tangram runs on frontier models, never locked to one vendor, so it improves as the best models do.

Your tools. Your team.

  • Drive the model from a chat

    tangram already works inside Claude, drive your model from a Claude session, with agents acting on real building objects without leaving the chat. More integrations are on the way.

  • Open formats, in and out

    IFC in and out, PDF sheets out, with more wiring every week. The aim: tangram plugs into every tool you already use.

  • Everyone on the same model

    Coming soon

    Already one model for the whole team. Coming soon, everyone works on their own copy, always in sync, with every change signed, dated and traceable.

Questions

What people ask us.

How can I trust the numbers?

The AI produces no numbers. Areas, volumes and drawings are measured on the model, and every quantity points back to its elements.

Do I need to install anything?

No: tangram opens in a recent desktop browser.

Which AI do I need?

Frontier models, with no lock-in to one vendor: your Anthropic, OpenAI or Z.ai key, or tangram driven from a Claude session. Connecting from ChatGPT is in progress.

Where is my data?

In your browser and in the files you export (IFC, PDF, .tangram).
