Castly

Castly is an AI writing service that helps you turn ideas into publish-ready text through a simple conversation. Start chatting, ask questions, share rough thoughts, or upload documents to get structured drafts you can refine.

Chat-based writing and document support

Use Castly to have an open-ended dialogue with AI or to generate text based on your uploaded files. It works well for content that needs to reflect your notes and source materials.

• Articles and blog posts
• Notes and summaries
• Emails and letters
• Social posts and short-form copy
• Drafts built from your documents

Built-in editor for polishing drafts

Castly lets you select strong parts of the conversation and move them into an integrated editor in one click. From there, you can revise structure, tone, and wording to turn an AI draft into a clean final version.

Faster creation and sharing

Castly is designed to reduce steps from first idea to final text. After editing, you can share the result with teammates or publish it in your preferred channels, using Castly as a central workspace for text.
