About the app & 20 tutorialsLEARN BY DOING / 02
From an idea to something you made.
Choose a small goal and start with one tutorial.
Aquarell getting started: create a canvas, draw in layers and export PNG
Start with a simple drawing exercise to learn canvas settings, the role of each layer, brush adjustments and PNG or native-project export in Aquarell.
ManYue getting started: import local comics and read offline
Start with your own CBZ, CBR or PDF to learn local comic import, shelf selection, offline reading and common issues in ManYue.
VectorPaint getting started: build an icon from shapes and export SVG
Start with a small icon made from circles and rectangles to learn canvases, fills and strokes, layer organisation and the choice between SVG and PNG.
Book Isle getting started: import your first EPUB and resume reading
Import a local EPUB, jump between chapters, save your position and check offline access, without mistaking a remote cover for downloaded text.
iCouldPlay getting started: add a local video to your media library
Import your own video from Files, check the local source, picture, sound and viewing progress, and understand the relationship between the library and original file.
Yearn getting started: import your own first game and exit safely
Begin with a ROM you supply, then import it, confirm its platform, check controls, save manually and verify after exit for a clear first-use workflow.
IN MOTION / CREATIVE PROJECTS
Watch a piece take shape.
Recorded workflows, with written steps to follow at your own pace.
Cloud Mountains, Evening Ferry: paint an ink landscape with Aquarell MCP
Build distant mountains with pale washes, add rock contours and texture, then paint an old pine, a riverside pavilion and a small boat through Aquarell MCP. Follow the native brushes, open space, editable text, saving and export of a 1600×1100 px, 19-layer landscape, with a full-app tutorial video.
Midnight Orchid: build a moonlit conservatory with VectorPaint MCP
Six pale pink orchids surround a glass conservatory at night, with a moon, stars and reflections in deep blue-green. Create editable paths, gradients and text through VectorPaint MCP, keep the original and export a native 1200×900 px PNG, with a real-canvas creation video.
