Bring your own key
Any OpenAI-compatible endpoint — stored locally, called directly from your browser.
Fast picks: gpt-4o-mini · llama-3.3-70b (Groq) · gemini-2.0-flash. Big "thinking" models spend minutes before the first word — that's the model, not the connection.
AI INSIDE YOUR GENERATED APPS (NEW BUILDS ONLY)
Applied when Kiln creates a brand-new site — never injected into edits or redesigns of existing pages.
BRAND KIT — APPLIED TO EVERY NEW BUILD
Use brand kitPalette, fonts and tone below are injected into every build prompt.
APP LOGO — SHOWN EVERYWHERE IN KILN
Custom logoUpload Untitled106_20260913185017.png (or any image) — auto-resized & saved locally. Kiln also auto-loads that exact filename if it sits next to this HTML file.
IMAGE MODEL — AI FOR KEY SHOTS, FREE STOCK FOR THE REST
Only the top hero/brand images use your endpoint; every other image slot becomes a free keyword-matched stock photo (no key, no cost) or a CSS gradient. Set 0 to never spend AI images. Unlimited slots per site.
Auto-fill images after each buildParallel generation while the HTML streams; leftovers filled automatically.
Reasoning modeLet the model think before writing. Sharper results, slower start. Unsupported endpoints are retried without it.
Keys are saved only in this browser and sent straight to your chosen endpoints — no middleman.

Applied to every new build when enabled.

Import a site
Fetch a live URL or paste HTML — then edit it with AI.
Direct fetch first; if the site blocks browsers (CORS), public proxies are tried automatically.
OR PASTE HTML
Imported as a new project — content is preserved exactly.
Missing pages detected
These are linked from your site but were never generated.
On GitHub Pages these links would show a 404. Generate them with AI (matching your site's design), or export now with styled placeholder pages that link back home.
