This tool takes the raw transcript from any YouTube video and turns it into a structured, SEO-optimised blog post - complete with a title, meta description, and H2 headings. It is built for content teams, marketers, and solo creators who want to repurpose video content without spending hours rewriting from scratch.

The generator runs on Claude Haiku, Anthropic's fast, lightweight language model. Your transcript is sent securely to Anthropic's API for processing and is not stored or used for training. The tool complies with UK GDPR and the Anthropic Privacy Policy as of March 2026. Always review the output before publishing - AI-generated content should be treated as a first draft.

Frequently Asked Questions
What AI model does this tool use?
The tool uses Claude Haiku by Anthropic - specifically the claude-haiku-4-5 model. It was chosen for its speed and ability to follow structured formatting instructions reliably. Anthropic is an AI safety company founded in 2021, and Claude is their primary language model family.
Is my transcript stored or used to train AI?
No. Your transcript is sent to Anthropic's API solely to generate the blog post. Anthropic does not use API inputs to train its models by default. You can read the full details in the Anthropic Privacy Policy. JohnB.io does not log or store the content you submit.
How long can the transcript be?
The tool accepts transcripts up to 50,000 characters, which covers most YouTube videos including longer-form content and hour-long talks. If your transcript is longer, trim it to the most relevant sections before pasting.
Will the output pass AI detection tools?
No, and this is stated clearly on the page. AI-generated text is detectable by tools such as GPTZero and Originality.ai. You should treat the output as a draft and rewrite it in your own voice before publishing, particularly if your platform or client has an AI content policy.
What is the daily usage limit?
There is a per-IP daily limit to keep the tool available for all users without a login requirement. If you hit the limit, it resets at midnight UTC. For higher-volume use, get in touch to discuss options.
How It Works
  1. Open the YouTube video you want to convert into a blog post.
  2. Get the transcript: click Show more under the video description, scroll down and click Show transcript. In the transcript panel, open the three-dot menu and turn off timestamps.
  3. Select all the transcript text, copy it, and paste it into the input box on this page.
  4. Click Generate Blog Post. The transcript is sent to Claude Haiku, which structures it into a readable article with a headline, introduction, body sections, and a conclusion.
  5. Review and download. The output includes an SEO preview showing your title and meta description. Copy the text, download as TXT, HTML, or Word, or share directly to social media.
Key Points
  • Works with any YouTube transcript. As long as a video has a transcript - auto-generated or uploaded - this tool can process it. Typical turnaround is 30 to 45 seconds.
  • SEO structure built in. Every output includes a page title, H2 subheadings, and a meta description designed to help the post rank in search results.
  • Best used as a first draft. The tool speeds up the writing process significantly, but the output will benefit from a human edit. Add your own examples, check facts, and adjust the tone to match your brand.
  • No account needed. There is no login or sign-up. The tool is free to use with a daily usage limit per IP address to keep it available for everyone.
  • Download options included. Export your post as plain text, HTML, or a Word document - ready to paste into your CMS or share with a client.
