Comparison
Trade-off scorecard
| Pick | Price friction | Capability gap | Setup friction |
|---|---|---|---|
| Writesonic | $79/mo entry buys a bundle of GEO tracking, SEO audits, and articles — steep if you only want the writer | Article caps by tier (15/mo on Starter, 25 on Basic, 50 on Growth) rather than unlimited generation | More onboarding than a plain writer since the product expects a site to audit, not just a topic to write about |
| Jasper | Per-seat pricing; the useful tier above Pro is custom-quoted | Built around brand-voice training — most valuable once that voice is set up, less so for a single one-off post | Brand Voice and Knowledge asset setup is real work that pays off more at team scale than for solo writing |
| Rytr | Cheapest of the four, but Unlimited and Premium still gate multi-language support and higher plagiarism-check volume | Generation is short-form and click-based; producing a long post takes stitching several generations together rather than one continuous draft | Simple to start, minimal onboarding |
| Copy.ai | $29/mo Chat plan (5 seats) is the only self-serve tier below a $1,000/mo Growth jump — no mid-tier option | Current positioning leans toward marketing workflow automation rather than a dedicated long-form article writer | Workflow-based interface has more of a learning curve than a simple prompt-and-generate writer |
“Best AI tool for blog post writing” turns out to be a moving target — the tools that used to compete head-to-head as blog writers have mostly repositioned into broader platforms, and pricing has shifted with them. This comparison looks at four commonly recommended options: Writesonic, Jasper, Rytr, and Copy.ai.
How we compared
This is built from each vendor’s public pricing page, published feature lists, and commonly cited third-party reviews — not from hands-on use of the products. Where a number wasn’t independently confirmable at publish time, it’s described as a range instead of a precise figure. Pricing for AI tools changes often, so confirm current numbers on each vendor’s site before subscribing.
Writesonic
Writesonic’s pricing page lists Starter ($79/mo, billed annually), Basic ($199/mo), and Growth ($399/mo) tiers, plus a custom-quoted Enterprise plan. Each tier includes a capped number of AI articles per month (15 on Starter, 25 on Basic, 50 on Growth) alongside site audits and AI-visibility tracking — the article writer isn’t sold on its own. According to Writesonic’s product pages, the Instant Article Writer can produce a draft of roughly 1,500 words in about 20 seconds from a topic or prompt, and the Sonic Editor supports longer sessions past 2,000 words, with an SEO Checker & Optimizer that scores content against live search data as you write.
Who it fits: writers or small teams who also want AI-search visibility tracking and SEO auditing bundled in, and don’t mind the higher entry price for that bundle.
Jasper
Jasper’s Pro plan is listed at $69/mo per seat billed monthly, or $59/mo per seat billed annually, with a 7-day free trial. It includes the Canvas editor, marketing agents, two trained Brand Voices, and a handful of Knowledge assets. A Business tier adds advanced agents (including GEO features), an API, and enterprise governance, but is custom-quoted and requires a 12-month commitment per public pricing trackers.
Jasper’s core pitch for blog writing is consistency: content generated against a trained Brand Voice so a team’s output reads like one writer even when several people are producing it. Reviewers commonly note this as Jasper’s strongest differentiator over a plain prompt-and-generate tool.
Who it fits: teams producing blog content regularly enough that training and reusing a brand voice pays for itself.
Rytr
Rytr’s pricing is the simplest of the four: a free plan (10,000 characters/month, roughly 1,500 words, no card required), an Unlimited plan at $9/mo (or about $7.50/mo billed annually), and a Premium plan at $29/mo (or about $24/mo billed annually) that adds 35+ language support and a higher plagiarism-check allowance. Rytr’s own use-case pages list 40+ templates spanning blog ideas, outlines, section writing, and SEO meta descriptions.
The catch reviewers commonly point out: Rytr generates in shorter blocks per click rather than one continuous long-form pass, so assembling a full blog post typically means running several generations and stitching them together — a different workflow than Writesonic’s or Jasper’s single-document editors.
Who it fits: budget-conscious solo writers who want short-form generation building blocks rather than a single long-document writer.
Copy.ai
Copy.ai’s current pricing page lists a Chat plan at $29/mo (or $24/mo billed annually) covering 5 seats, unlimited words in chat, and access to several underlying model providers, then jumps to a Growth plan starting at $1,000/mo billed annually with workflow credits and many more seats — there’s no self-serve tier between the two. Public listings do not show a permanent free plan on the current pricing page, though older third-party trackers describe one; confirm at signup.
Copy.ai’s positioning has shifted toward marketing workflow automation (its own site now frames it as a “GTM AI Platform”) rather than a dedicated blog-writing tool, though its chat interface and templates can still produce long-form drafts.
Who it fits: teams that want blog writing as one piece of a broader marketing workflow, and can justify either the $29/mo entry tier or the much larger Growth jump.
Bottom line
For a single long article written in one editor, Writesonic and Jasper are the two built for that job — Writesonic if AI-search visibility and SEO auditing are also useful to you, Jasper if a consistent brand voice across writers matters more. Rytr is the cheapest way in but fits shorter-form output better than one continuous long post. Copy.ai is worth a look only if you want blog writing folded into a broader marketing workflow tool. None of these figures are final — check each vendor’s current pricing page before you commit.
Anyone who wants a single cheap tool that only writes blog posts. Writesonic and Jasper have both moved toward broader platforms (AI-search visibility, brand governance) priced accordingly. Rytr stays closest to a plain writer, but its short-form generation model is a worse fit for long articles than the other three.
Solo bloggers on a tight budget who need long, well-researched posts. The tools built for a single long document (Writesonic, Jasper) start at $59-79/mo. Rytr is cheaper but not built for one continuous long draft. None of the four replaces the research and fact-checking a well-researched post needs.
Frequently asked questions
What's the best free AI tool for writing blog posts?
Rytr's free plan is the most usable no-cost option here — 10,000 characters a month (roughly 1,500 words) with no card required, enough to draft a short post or test the tool before paying. Writesonic and Jasper both gate blog writing behind a paid plan after a short trial, and Copy.ai's current pricing page does not list a permanent free tier.
Can any of these tools write a full blog post in one pass?
Writesonic's Sonic Editor and article writer are built for a single long document and list support for drafts over 2,000 words in one session. Jasper's Canvas works the same way against a target brand voice. Rytr generates shorter blocks per click, so a full-length post is usually assembled from several generations rather than one continuous draft — reviewers commonly describe it as better suited to shorter pieces.
Do I still need to edit AI-written blog posts before publishing?
Yes. Every vendor here markets its output as a first draft or assistant, not a finished, fact-checked article. Reviewers across all four tools consistently flag the need to verify facts, statistics, and any claims before publishing, and to edit for a voice that doesn't read as generic.
Is Writesonic still just an AI blog writer?
No, and this trips up a lot of older comparisons. Writesonic's current pricing page bundles the AI article writer into a broader platform built around AI-search visibility (GEO) and SEO auditing — the article writer is one component, not the whole product, and the $79/mo entry price reflects that bundle.
