🛠️ Stack

• Void — The full-stack foundation: routes, auth, D1 and background jobs on Cloudflare.
• Jev by TypeSafe — Compares each post with your bio and project, rates how relevant it is, and finds where your common ground appears in the post.
• Cloudflare AI Gateway — Model requests, logging and unified billing.
• Cloudflare Browser Run — Reads project pages and captures each post so its common ground can be highlighted.
• React — The interface and its reusable components.
• Motion — Transitions, gestures and feedback as you browse and keep people.

🌱 Why this exists

X’s published algorithm includes a mutual-follow boost: extra weight for predicted replies to original posts from people you mutually follow.

Our bet is simple: find people with shared interests, and give each other a reason to keep reading and replying. hashtagconnect helps make that first connection.

How it works

🔎 Browse	✨ Find common ground	🤝 Connect
Explore #connect posts in their original X embeds.	Sign in to see how each post relates to your bio and project, with the common ground highlighted in the post.	Keep people in your Stash, then open their profiles on X.

A project link in your bio fills out your context automatically. You can also add a link yourself, and review or edit your context in Settings.

Status: a side project, built because I wanted to use it myself.

Built by AI agents, steered by a human. Developed with Codex and Claude Code; product direction and final decisions stay human.

Run locally

Requires Node.js 24.21.0 or newer and pnpm 11.25.0.

pnpm install --frozen-lockfile
cp env.example .env
pnpm exec void db migrate
pnpm run dev

Open http://127.0.0.1:5173. Before committing, run pnpm test and pnpm check.

For sign-in, configure an X OAuth Web App with this callback:

http://127.0.0.1:5173/api/auth/callback/twitter

Add its client ID and secret to .env. For scans, fill in the Cloudflare AI Gateway credentials in env.example. Project reading and embed captures use Browser Run: set your Cloudflare account in void.config.ts and authenticate Wrangler.
