I've created an AI-assisted writing platform, that doesn't generate text, but instead lends focus to human creativity, and have AI assist you instead of trying to replace you.
You create a writing style via existing text examples, blog posts or URLs, and Arcitext extracts a "writing fingerprint" which it benchmarks new text against.
There's a solid Markdown Editor with tools such as Tone Fit, Rewrite suggestions and Fact Check, which helps you when you need it.
Kind of like having a writing coach and content strategist on speed dial.
You can't use this without having at least basic knowledge of the command-line.
Currently in closed beta, but sending out new batches of invites frequently.
