Step 0: Start with one prompt

Claude chose what to make and wrote this prompt, with the Rainbrand MCP connected.

Use Rainbrand and Heart Aerospace’s brand to turn Heart’s own line, “X1 is the proof. ES-36 is the product.”, into three concept pieces: a silent 4:5 video of X1’s first flight made from Heart’s own photographs, a 50 × 70 cm thank-you poster for the terminal at Plattsburgh International Airport, where X1 flew, and an interactive ES-36 route check that compares the distance between two airports with the aircraft’s published range. Take every fact from Heart’s own pages and label the work as concepts.

Step 1: Add a brand

Added to Rainbrand from heartaerospace.com (opens in a new tab), with the logo and photos from its pages. A sample of what Claude could use:

Step 2: Ask for Briefs

Claude added 9 of Heart’s own images to the Brand Library, then asked for 2 Briefs: one for the video and poster, one for the route check.

For the video and the poster

Claude asked for

rainbrand · create_brief

task: “Make two concept pieces marking the first flight of Heart Aerospace's X1, using Heart's own flight-test photography and only facts from Heart's published account (its 13 August 2026 newsroom release and the /x1 page). (1) A silent 4:5 video of about 24 seconds for Heart's LinkedIn and Instagram feeds. It follows the flight of 12 August 2026 at Plattsburgh International Airport, New York, through Heart's photos in order: taxi, takeoff and climb, sunrise over Lake Champlain, touchdown. Short on-screen lines carry the published facts: a 27-minute flight, 1,100 ft above ground, more than one megawatt of electric power, about $5 of electricity, the largest battery-electric aircraft ever flown. It ends on Heart's own line 'X1 is the proof. ES-36 is the product.' and the logo. (2) A 50 x 70 cm portrait poster for the passenger terminal at Plattsburgh International Airport, where X1 flew: a thank-you to the airport and its community that says what happened on their runway, with one hero photograph and the same facts. Keep X1 battery-electric and distinct from the ES-36. I need the logo rules for photography and dark fields, the display and text typefaces, the palette, flight-test imagery to use, the voice for short headlines, the limits on claims, and the photo terms.”

For the route check

Claude asked for

rainbrand · create_brief

task: “Design a responsive web tool concept, 'ES-36 route check', for regional airline network planners, airport teams and journalists. They pick two airports from a list of about 80 in North America and Europe and see the great-circle distance between them, and whether it falls within the ES-36's published all-electric range (125 mi / 200 km) or its hybrid range (745 mi / 1,200 km). A ring diagram centred on the departure airport shows every other airport in the list inside each range. The tool must present the ranges as Heart's published aircraft specifications, not guarantees for any route or condition; say that entry into service is targeted for 2031; and say it is a concept, not a Heart Aerospace product. I need the website look (layout, colours, type, buttons and form controls), where and how the logo sits, ES-36 imagery for the header, the voice for short interface copy and result lines, and which range and emissions claims are allowed.”
