You'll need an Anthropic API key. Get one at console.anthropic.com.

Your API key stays in your browser only — it is never sent to our servers. This project is fully open source so you can verify this yourself.

How it works

1. Discover — Scans the web for articles published in the last 2 days in your niche. Returns up to 4 trending topics with real sources, verified URLs, and fresh angles.

2. Discuss — Chat with an AI thought partner. It challenges your thinking, finds data, pulls perspectives from X/Reddit, and proposes an outline when you're ready.

3. Publish — Generates an X thread (or long-form post for Premium users), a LinkedIn post, and an Obsidian note with sources. Everything is editable before you copy.

Features

• Real source verification (AI checks every URL)
• Markdown rendering in chat with Raw/Copy toggle
• Editable draft outputs with character counts
• Session persistence (resume where you left off)
• Draft history (last 50 saved locally)
• Model selection (Economy / Balanced / Quality, or per-stage Advanced)
• X Premium long-form support with 280-char fold indicator
• User persona config (audience, tone, industry)
• Responsive design (works on mobile)
• Accessibility hardened (ARIA, focus indicators, touch targets)
