Newsletter creators spend 3-4 hours per issue rewriting their content for LinkedIn, X, Bluesky, Substack Notes, Threads, Instagram, and Reddit — each platform has its own rules, voice, and length. Letterfork compresses that work to 60 seconds. Paste your Substack / Beehiiv / Ghost URL (or raw...

Features and specs

What each product offers, as listed by its team.

Iframely 5 features
Letterfork 6 features
  • “No code”
    Instead of API calls, an option to use our HTML template and some JavaScript spice.
  • JSON
    Only two endpoints to choose from and connect: complete Iframely data or a simple oEmbed connector. Both have the html field for you to embed.
  • Cards and URLs previews
    Engage your users with URL preview cards, just like they expect in a modern app. Change cards design easily in your settings.
  • React and JavaScript
    React, and other JavaScript runtimes won’t let you run third-party scripts. Iframely fixes this by hosting media in an iFrame instead.
  • Responsive embed codes
    Rich media will resize and fit your site’s design on any device, with a correct aspect ratio or a horizontal height.
  • Output platforms
    LinkedIn, X, Bluesky, Substack Notes, Threads, Instagram, Reddit
  • Input formats
    Newsletter URL (Substack, Beehiiv, Ghost) or raw text

Questions & Answers

As answered by people managing Iframely and Letterfork.

What makes your product unique?

Letterfork's answer:

Two things, together. Voice cloning that learns from your own past writing — rhythm, opener moves, contraction frequency, tic-words — so the output sounds like you, not ChatGPT. And per-platform formatting rules that match how the best writers actually post: LinkedIn opens with a hook in single-sentence paragraphs; Bluesky chains run 300-char chunks without "🧵 1/" thread tics; Substack Notes ends in a stance or question; Reddit reads as a member, not a marketer.

Most repurposing tools nail one or the other. Letterfork does both in a single paste.

Why should a person choose your product over its competitors?

Letterfork's answer:

Most alternatives stop at "AI rewrites your post." Letterfork goes further on three axes:

Voice — cloned from your own writing samples, not a generic LLM template. Your readers won't smell ChatGPT. Coverage — 7 platforms in one paste (LinkedIn, X, Bluesky, Substack Notes, Threads, Instagram, Reddit). Repurpose.io is a publisher; Typefully covers X+LinkedIn; Supergrow is LinkedIn-only. Control — no auto-publishing. You read every output before it goes live.

Plus a real free tier: 3 lifetime rewrites across all 7 platforms, no credit card.

How would you describe the primary audience of your product?

Letterfork's answer:

Newsletter writers spending 3-4 hours per issue rewriting content for LinkedIn, X, Bluesky, Notes, Threads, Instagram, and Reddit. Mostly solo operators on Substack, Beehiiv, or Ghost — anywhere from 500 to 50K subscribers.

The pain: each platform has its own voice, length, and conventions; copy-pasting the newsletter as-is reads as lazy. The job Letterfork does: compress that 3-hour rewriting into 60 seconds without losing the writer's voice.

What's the story behind your product?

Letterfork's answer:

I write a newsletter — The Super Lede on Substack — and got tired of burning 3-4 hours per issue reformatting it for every platform. Generic AI tools either output sterile ChatGPT prose or auto-publish without me reviewing. Both made me look worse on the platforms where my readers actually live.

Letterfork is what I built to fix it for myself first. Now I'm shipping it for other newsletter writers stuck in the same loop. Building in public — find me as @superlede on X.

Which are the primary technologies used for building your product?

Letterfork's answer:

Next.js 16 (App Router), TypeScript, Vercel AI SDK with Anthropic Claude Sonnet 4.6 for rewriting + voice cloning, OpenAI GPT-4o-mini for output formatting, Supabase (Postgres + Auth + SSR), Stripe for billing. Hosted on Vercel with Speed Insights and PostHog analytics.
