Wordtune

Speechify

Freemium

Speechify reads text aloud through a Chrome extension, a web app and dedicated mobile or desktop apps. You can load a PDF, article, Google Doc or email and hear it in one of 1,000+ voices across 60+ languages, at speeds up to 5x. Word highlighting follows the audio, and the app can summarize long documents or turn them into audio conversations. Premium adds voice typing, AI podcast creation and Drive, Dropbox and OneDrive connections. The free tier caps playback at 1.5x speed and includes ten basic voices.

QuillBot

Freemium

QuillBot is a set of editing tools gathered around a paraphraser. You paste text and get rewritten versions in more than ten modes, including academic, formal and simple, or define a custom mode for a house style. Grammar checking, an AI detector, an AI humanizer, a plagiarism checker, a summarizer and a citation generator sit in the same account, which makes it useful for students assembling essays and for editors polishing client copy. The free tier caps paraphrasing at 100 words and two modes; Premium at $8.33 per month on annual billing lifts those limits and adds full detector and humanizer access.

Rytr

Freemium

Rytr has changed shape: it now remembers clients and commitments across email, Slack, calendars and meeting notes, then helps you write the follow-up. The writing side, called Create, offers more than forty use cases such as emails, ads and posts, with 22 tones and support for 38 languages, and can produce up to three drafts at once. A browser extension rewrites text in any input box, while Engage supplies morning briefs and meeting prep. The free plan allows 10,000 characters monthly; Lite at $9 per month removes the character cap.

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.
