Text & Writing

Sudowrite

Paid

Sudowrite is a writing environment for fiction authors rather than a general assistant. A Story Bible walks from premise to outline to chapter beats, and the drafting tools extend, describe, rewrite or continue prose in your own voice. Two in-house models built for narrative work sit alongside dozens of third-party models, and a feedback feature returns developmental notes, line edits and beta reads on finished drafts. Series continuity, style matching and character art round it out. Plans are credit-based, starting at $19 per month billed monthly ($10 yearly) for 225,000 credits, and the trial needs no card.

Writesonic

Paid

Writesonic began as a copywriting assistant but now sells itself as an AI search visibility platform that still writes. It tracks how often your brand appears in answers from ChatGPT, Gemini and Google AI Overviews, then drafts articles and runs site audits to close the gaps it finds. Plans are organized by prompt and answer volume, articles per month and seats: Starter covers 15 articles and ten audits monthly. There is no free plan, only a seven-day trial, and the entry price is $79 per month on annual billing, which puts it beyond most individual writers and aimed at agencies and in-house marketing teams.

Jasper

Paid

Jasper is built for marketing teams rather than individual writers. You load your brand voice, style guide and product details into its knowledge base once, then produce campaign copy, blog drafts, emails and social posts that follow those rules. The Canvas editor holds documents and campaigns in one workspace, while separate agents handle research, translation and checks on how your brand appears in AI answers. Collaboration and multiple brand profiles sit behind the Pro plan; larger companies get custom Business pricing with onboarding support. Only Pro is self-serve, billed at $59 per month yearly or $69 monthly, and a seven-day trial covers the Pro features.
