privateslm.dev — site

Static site: privateSLM landing, circuitAI landing, and the on-device AI blog.

Domain privateslm.dev is purchased through Vercel Domains. Hosting is migrating from GitHub Pages to Vercel to avoid manual DNS config (Vercel domains attach to Vercel projects with zero DNS records) and to avoid two live copies of the same site (duplicate content is bad for SEO):

1. Import this repo as a Vercel project (Framework Preset: Other — no build step, it's plain static HTML).
2. Project Settings → Domains → add privateslm.dev. Since the domain is owned by the same Vercel account, it attaches without copying any DNS records.
3. Once the Vercel deployment is confirmed working, disable the GitHub Pages deployment for this repo so privateslm.dev is the single canonical origin.

MegaBrain promotion

Every page carries an orange bar across the top ("For business · MegaBrain — Private AI for your business") that stays in view while the page scrolls, and every blog post ends with a banner in the same colour. Both come from scripts/promo.py:

python3 scripts/promo.py

It is idempotent, and gen_blog_meta.py and gen_model_pages.py call it when they finish, so new and regenerated pages get it without a separate step. The wording and the link are in that script; the colours are in assets/style.css under "MegaBrain promotion". A hand-written page needs nothing but <body> on its own line.

Blog posts (SEO)

Every post needs a <title>, a meta description, a canonical link and a date in <div class="meta"> ("July 20, 2026 · 8 min read"). The rest is generated — run this after adding or editing a post:

python3 scripts/gen_blog_meta.py

It writes the Open Graph tags, the Twitter card and the BlogPosting structured data into the post's <head> (between the seo:start / seo:end comments — do not edit by hand) and adds the post to sitemap.xml. The preview image is the first image in the article, or assets/og-default.png. To mark a revision, write "Updated October 11, 2026" in the meta line.

Model & compare pages (SEO)

models/*.html are generated — never edit by hand. Regenerate whenever models.json changes:

python3 scripts/gen_model_pages.py

The script also appends any missing /models/ and /compare/ URLs to sitemap.xml and refreshes the "## Model pages" section of llms.txt. compare/*.html are hand-written; keep every competitor claim verifiable and update the "Updated " line when facts change.

Search engines and assistants

ChatGPT's web search reads Bing's index, so a page Bing has not crawled does not exist for it.

• llms.txt is the site in one text file for assistants. The top (the summary and "Facts") is written by hand and must match the app and the App Store: when a price, a pack or a minimum OS changes, change it here, in the home page's facts table and FAQ, and in its JSON-LD. scripts/gen_model_pages.py rewrites only the "Model pages" section (models and every compare/*.html, by its <title>).
• IndexNow: the key is served at /b554a11595e2c5a99c976126fb9e55bb.txt. After a deploy, python3 scripts/indexnow.py sends the whole sitemap to Bing and the other IndexNow engines; python3 scripts/indexnow.py /compare/x.html sends one page.
• vercel.json sends /circuitai/ to circuitapp.app: CircuitAI became Circuit, an app blocker, in September 2026. circuitai/index.html does the same for hosts without that rule (GitHub Pages).
• privateslm.app is not ours. It was registered at GoDaddy on 2026-02-23 by someone else and shows a parking page; every domain we own is in Vercel. Never link to it — the site is www.privateslm.dev.
