A free AI writing assistant with a full canvas
Draft essays, blog posts and long-form writing with ArcAI's free writing canvas — powered by GPT-class models with persistent memory.
ArcAI's writing canvas gives you a dedicated space for long-form drafts with inline AI edits and persistent style memory — free.
A useful AI writing assistant should help with structure, voice, edits, outlines, rewrites, titles, summaries, and long-form drafts — not just produce generic paragraphs.
The important difference is consolidation. Instead of bouncing between separate tools for blog posts, essays, emails, scripts, ArcAI puts those workflows in one account with one memory system and one interface. That matters for searchers comparing assistants because the question is rarely just price — it is whether the product is useful enough to become a daily habit.
Writers can draft, edit, and analyze documents on our free tier, with persistent memory ensuring their style carries forward across drafts.
