PDF to MP3 — landing page micro-audit

Format of the $19 BTC micro-audit: 3 prioritized fixes, before → after, plus 1 metric to watch.

What the page says today

“Convert PDF to MP3”

“Control the playback sentence by sentence. Get more time to think and understand the text much faster.”

“Drop your PDF here”

Fix 1 (highest impact) — Hero: sell the control, not the format conversion

Before: H1 “Convert PDF to MP3” is commodity; the product edge is sentence-level control + Ask/Explain.

After:

H1: “Listen to any PDF — one sentence at a time.” Subline: “Pause, replay, ask, or get a simpler explanation before you move on.”

Fix 2 — CTA: drop-zone alone hides the OpenAI-subscription path

Before: Show HN push was “use your OpenAI subscription”; landing leads with upload only.

After:

Primary: “Drop a PDF to start”; secondary link: “Or connect your OpenAI subscription”.

Fix 3 — Offer: what is free vs paid is unclear above the fold

Before: No price or plan next to the drop zone.

After:

Micro-line: “Try with a short PDF free — connect OpenAI for longer books” (adjust to real plan).

Metric hypothesis

If Fix 1 + 2 ship, watch first successful PDF listen completions for 2 weeks against the current page; hypothesis only, no data from PDF to MP3.
