Last quarter I doubled my conversion rate by removing the pricing page from the funnel entirely. Counterintuitive, I know. The thinking: pricing pages are objection generators. When prospects see a number before they see value, they anchor on cost…

I doubled conversions by deleting our pricing page.

Sounds nuts. Here's the thinking:

Pricing pages are objection generators. Prospects see the number before they see the value, and anchor on cost.

What changed when we removed it? Sales calls got shorter. Closes got bigger. Curious how you'd test this.

Deleted our pricing page last quarter.

Conversions doubled.

Here's why pricing pages are killing your funnel:

Questions, answered

How is this different from ChatGPT?

ChatGPT doesn't know your voice. You'd spend 30 minutes per platform crafting a prompt, and even then output reads generic. Letterfork extracts your style once and reuses it forever — and ships platform-native formats (X thread pacing, LinkedIn hooks, IG hashtags) without you specifying them.

Which platforms are supported?

Five at launch: LinkedIn posts, X (Twitter) threads, Substack Notes, Threads, and Instagram captions. Reddit and Medium are on the roadmap.

Can I edit the output?

Yes — every output is plain text, copy-pasteable. We don't auto-publish; you stay in control.

Do you train on my newsletters?

No. Your past newsletters are used to extract a one-time style description that lives in your account. We never train models on your content, and your data is never shared.

What if my newsletter is paywalled?

Paste the full text directly. Letterfork's URL parser only works on publicly visible newsletter pages.
