Grammarly — the everyday editor

Grammarly is the writing assistant almost everyone can use. It checks grammar, spelling, clarity, and tone in real time across your browser, email, docs, and desktop apps, and its generative AI can now draft and rewrite too. It won't build a whole marketing campaign, but for making everything you write clearer and more professional, it is the most polished editor available.

QuillBot — the paraphrasing champion

QuillBot is best known for the web's finest paraphrasing tool, with multiple rewrite modes that reword text while keeping its meaning. Around it sits a strong grammar checker, summarizer, translator, and citation generator. For students, researchers, and anyone who rewrites and refines more than they draft from scratch, QuillBot is hard to beat — and its free tier is excellent.

Price Comparison

Prices shift with promotions, but the entry paid tiers show how each tool is positioned:

• Rytr: a generous free plan, with Saver from around $9/month and Unlimited around $29 — the cheapest way to generate a lot of content.
• Grammarly: a capable free tier, with Pro at around $12/month (billed annually) unlocking full generative AI, tone rewrites, and advanced suggestions.
• QuillBot: a strong free tier, with Premium at around $10/month (billed annually) removing paraphrasing limits and unlocking all modes and tools.
• Jenni AI: a limited free plan, with Unlimited at around $12/month (billed annually) for unlimited AI words and citations.
• TextCortex: a free tier of daily creations, with Lite from around $14/month for more creations, knowledge bases, and premium features.

The takeaway: Rytr and QuillBot are the most affordable, while all five land in a similar $9–$14 range at their entry tiers — cheap next to a $20/month general chatbot. If your budget is tight and you want to generate content, Rytr wins on price; if you mainly rewrite, QuillBot's free tier may be all you need. Watch for the annual-vs-monthly gap, since monthly billing can cost noticeably more.

Writing Quality

When you need the AI to actually produce text, output quality and control matter most.

Rytr generates clean, on-brief marketing and blog copy quickly, and its tone and use-case presets keep it consistent — great for volume, though longer pieces benefit from editing. Jenni AI produces the most substantial long-form and academic prose, continuing your argument sentence by sentence rather than dumping a generic essay. TextCortex writes competently across formats and gets better when pointed at your own knowledge bases. Grammarly and QuillBot can generate text too, but they shine most when refining and rewriting rather than drafting from a blank page. For pure generation, Rytr and Jenni lead in their respective lanes.

Editing & Grammar

Most writing is rewriting — so how well each tool fixes and polishes text is a category of its own.

Grammarly is the leader here: real-time corrections for grammar, clarity, tone, and style, available in nearly every app you type in, with the clearest explanations. QuillBot is a close rival, pairing a very good grammar checker with the best paraphraser on the web for reshaping sentences. TextCortex offers solid rewrite, expand, and tone tools inside its browser assistant. Rytr and Jenni include editing help, but it is secondary to their generation focus. If polishing existing writing is your priority, Grammarly and QuillBot are the two to beat.

Research & Citations

For academic and factual writing, sourcing and citations separate the serious tools from the rest.

Jenni AI is built for exactly this: in-text citations from real papers, a citation library, and a research assistant that helps you find and reference sources as you write — the strongest of the group for essays and theses. QuillBot backs it up with a handy citation generator and summarizer that students lean on. TextCortex grounds answers in your uploaded knowledge bases, useful for referencing your own documents. Grammarly and Rytr aren't research tools — they format and generate, but you supply the facts. For cited, evidence-based writing, Jenni is the clear choice.
