Frequently Asked Questions

At launch, Coriolis runs concrete design to AS 3600:2018. Eurocode (EN 1992-1-1:2004) and US (ACI 318-19) concrete support is on the roadmap, along with the cold-formed steel codes — AS/NZS 4600:2018, AISI S100-16, and EN 1993-1-3:2006. Calculation results cite the code clause they derive from, where the calculation maps to a specific clause.

We verify Coriolis against published design standards, independent reference solutions and worked examples, and we run a benchmark suite continuously against the engine. Results cite the code clause they derive from where the calculation maps to a specific clause, and those citations carry through to the PDF reports. Each tool's user guide describes what that tool is designed for, together with the limitations we have identified for it. Coriolis is a design aid — results must be independently checked by the engineer of record before they are relied on.

Yes. Generate professional PDF reports with a single click. Reports include full calculation breakdowns with code clause references, suitable for checking and project documentation.

Coriolis supports the Model Context Protocol (MCP), allowing AI assistants like Claude to run analyses, create sections, and generate designs programmatically. This lets you automate repetitive tasks and explore design alternatives faster.

Integraph is a structural engineering software company based in Australia. We build browser-based design tools for professional engineers, focused on accuracy, usability, and modern workflows.

Integraph is the company; Coriolis is our structural design application. You sign in to Coriolis at app.integraph.com.au with an Integraph account.

Yes. All data is stored on AWS infrastructure with encryption at rest and in transit. We follow industry best practices for data security and access control.

Coriolis is a browser-based application and requires an internet connection. However, your work is automatically saved as you design, so you never lose progress.

Yes. The GCS — General Cross Section tool is free — no credit card required. Every other tool comes with a 14-day free trial with full access, so you can try it before you subscribe.

Basic and Pro plans are priced per tool, per user. Each Basic-plan tool is £9 per user per month, so subscribing to two of them comes to £18. The GCS — General Cross Section is always free. Prices are exclusive of GST, VAT or other applicable sales tax, which is calculated and added at checkout based on your location.

You can subscribe from anywhere Stripe operates, including the EU and the UK. On most purchases Link, a Stripe service, is the merchant of record — it calculates and remits any sales tax, issues your tax invoice, and appears on your statement as LINK.COM* INTEGRAPH.

Coriolis works in all modern browsers including Chrome, Firefox, Safari, and Edge. We recommend using the latest version for the best experience.

Yes. All platform features are accessible via a RESTful API. We also support the Model Context Protocol (MCP) for AI assistant integration. See the API & MCP page for details.

The Pro tier includes programmatic access via REST and MCP. Each call is metered in credits against a per-user balance — the balance refills at the start of every billing period, and the included allowance scales with how many Pro entitlements you're paying for. If you exhaust it mid-period, you (or your billing-org owner) can approve a top-up via Stripe Checkout. Credits you buy do not expire, though spending them needs a current Pro entitlement — if yours lapses the credits are retained, not forfeited, and become spendable again when it resumes. When the balance hits zero, the API returns a clear error instead of running up an overage charge, so spend stays bounded. Per-call prices are published live and surfaced on every response. See the API & MCP page and the Subscriptions and trials doc for details.
