Hook Lab

Five versions of your opening line, judged before you post.

You rewrite your first line nine times, post the ninth, and still wonder if version four was the one. Test hooks on Claude before you test them on your audience.

Show the prompt ▾
Create an interactive, AI-powered artifact called Hook Lab that can call Claude from inside the app. I'll paste a draft hook or opening line, pick a platform (LinkedIn, X, Instagram, or YouTube) from a dropdown, and choose a vibe (bold, curious, contrarian, or friendly). When I click 'Spin 5 variations', ask Claude to rewrite my hook five ways — a question, a bold claim, a story tease, a surprising stat angle, and a contrarian take — and show them as side-by-side cards, each with a one-line note on why it might stop the scroll. Add a 'Face-off' button that asks Claude to pick the strongest two and explain why. Let me star favorites and copy any card with one click. Keep all state in React, no login or saving needed. Style it playful and punchy: big type, rounded cards, one bright accent color.

You get: A little writing gym where one pasted hook becomes five comparison cards with verdicts. This app thinks for itself — it calls Claude from inside the artifact, and it works on the Free plan.

Your data: Nothing is saved between visits, so copy your winning hooks out before closing the tab — the starred cards make that a one-click job.

Remix it

  • Add a 'Steal this format' library of 10 classic hook templates I can fill in with my own topic.
  • Let me paste three past hooks that flopped so Claude can diagnose the common problem.
  • Add a character counter with per-platform limits so I know when a hook runs too long for X.

Newsletter Section Planner

Every issue mapped out before you write a word.

Newsletter dread is rarely about the writing — it's staring at a blank doc wondering what goes where. A standing section map turns 'write the newsletter' into 'fill in six boxes.'

Show the prompt ▾
Create an interactive artifact: a newsletter issue planner. Start with editable recurring sections — Intro, Main Story, Quick Tips, Tool of the Week, Community Corner, and CTA — that I can rename, reorder, add, or delete. Each section gets a title field, a notes box for the idea, a target word count, and a status toggle (idea, drafting, done). Show a progress bar across the top and a running total of target words for the whole issue. Add an idea parking lot column on the side where I can jot loose ideas and drag them into a section. Include a 'Copy plan as text' button that formats the whole plan as tidy Markdown I can paste anywhere. Keep everything in React state, no login needed. Friendly visual style: soft colors, card-based layout, satisfying checkmarks when a section flips to done.

You get: A card-based planning board with your recurring sections, word budgets, status toggles, and an idea parking lot — plus a one-click Markdown export of the whole plan.

Your data: The plan lives only while the tab is open — hit 'Copy plan as text', stash it in your notes, and paste it back next session (Pro users can publish the artifact and add built-in persistent storage instead).

Remix it

  • Let me paste last issue's exported plan back in to duplicate its structure for the new issue.
  • Add a content balance meter that warns me when the issue is all links and no original writing.
  • Turn the parking lot into a priority list with a 'this week / someday' toggle on each idea.
