🛠️ 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.
