Built for the work after conversion
Clean Markdown, saved once, shared with control.
CTXbase is not just a file picker. It gives converted content a lifecycle: prepare it, inspect it, save the approved Markdown, and expose it through read-only access when another tool needs the same context.

Review
Human approval
Inspect the generated Markdown before it enters your library or gets shared.
Save
Markdown only
Keep only the Markdown result and the metadata needed to manage it.
Share
Read-only access
Create read-only access links so approved tools can reuse the same context.
Workflow
A calmer path from source material to reusable context.
The homepage now explains the product flow below the hero instead of leaving users with a thin list of cards.
Choose a source
Upload a supported file, paste a web page, or start with raw text.
Generate Markdown
CTXbase extracts the useful content and removes the layout noise.
Approve the result
Copy, download, or save the Markdown only when it looks right.
Reuse safely
Share approved Markdown through read-only access instead of sending files again.
Resource tools
Every SEO tool page starts from the same converter.
Dedicated pages can focus on a keyword, but the product experience stays consistent: one strong converter with broad format support.
