What is Model Context Window?
How much conversation, code, and history a model can consider at once. Long builds need compaction and stable model selection so decisions survive across sessions.

Session Compaction
Summarizing long build conversations so work continues within context limits without losing decisions. Compaction plus model lock keeps multi-session projects coherent.
Chat Mode vs Act Mode
BYOB’s two gears: Chat Mode reasons, explains, and plans without touching files; Act Mode edits code, connects services, and moves the project forward. Strategy first, implementation when decided.
Preflight Plan
The setup pass before generation: refining the prompt, identifying features, proposing UX direction, and choosing data options. Planning first is what separates coherent apps from random screens.
One-Click Deployment
Publishing a site to production hosting without manual configuration. BYOB deploys to an edge network with rollback to known commits when a release misbehaves.
Custom Domain
Your own address (you.com) instead of a builder subdomain, with automatic SSL. The trust baseline for anything commercial: subdomains convert worse and rank no better.
Visual Editing
Clicking page elements in a live preview and asking the AI to refine text, spacing, or layout. It keeps non-developers in flow while the underlying code stays standard and editable.
