See what one credit produces on a plan built around real per-post cost, not a bare subscription number.
Search “AI blog writer for WordPress cost per post,” and you’ll get a dozen different answers, because there isn’t one pricing model behind that phrase. Some tools charge a flat monthly fee no matter how much you publish.
Others meter you by credits, words, or images. A few are technically free but bill you separately for the AI model doing the actual writing. None of that shows up in a marketing page’s headline price, which is why so many people end up paying more than they expected for what looked like a cheap AI blog writer plugin.
This post breaks down the actual pricing models in the market, what a realistic cost per post looks like at each tier, and the line items that tend to get left out of the comparison.
Table of contents
Key takeaways
- AI blog writer pricing for WordPress mostly falls into three models: flat subscription tiers, credit or usage-based plans, and per-word or per-post add-ons. Each one hides its real cost in different ways.
- A “cheap” AI blog writer plugin on the surface can end up costing more per finished post once you factor in a separate API key bill, image generation, and the editing time needed to make the output publishable.
- Published pricing for comparable tools ranges from under $20 a month for a single-feature add-on to $499 a month for high-volume agency plans, so “AI blog writer WordPress plugin pricing” isn’t a single number; it’s a spectrum tied to volume and what’s included.
- Edysor starts at $29/mo for 30 credits, with Growth at $79/mo (100 credits) and Agency at $199/mo (300 credits; extra credits at $0.50 each). Every tier runs on a credit-based model with generation and image costs built in, so you don’t need a separate API account to fund the subscription.
What Actually Determines the Cost of an AI Blog Writer
Before comparing numbers, it helps to know what you’re being charged for. Four variables drive most AI blog writer WordPress plugin pricing:
- Volume. How many posts, words, or credits are included before you hit an overage or have to upgrade.
- Model access. Whether the price includes the underlying AI model’s usage cost, or whether you’re expected to bring your own API key and pay the model provider directly.
- Media generation. Featured images, infographics, and charts are often billed as a separate line item or a smaller quota inside the same plan.
- Post-processing. SEO metadata, internal linking, formatting for WordPress blocks, and any compliance or fact-checking pass. Tools that only generate raw text tend to be cheaper up front and more expensive in editing time later.
The sticker price tells you what the subscription costs. It rarely tells you what a publish-ready post costs.
The Three Common Pricing Models
What real pricing looks like
Published pricing across current AI writing tools for WordPress illustrates the spread. WP AI Writer uses a straight credit-based subscription: a $29 a month Starter plan with 300 monthly credits, a $99 a month Pro plan with 1,500 credits, and a $499 a month Agency plan with 10,000 credits, with the listing noting plainly that API costs are not included in any tier (Capterra, 2026).
At the other end, eesel AI prices its blog writer around $99 a month for 50 full posts, a flat per-post rate rather than a credit pool, while AIOSEO’s AI add-on starts near $49.50 a year as a smaller feature bolted onto an existing SEO plugin rather than a full writer (eesel AI, 2026).
Divi AI sits closer to the add-on end too, at $24 a month for unlimited generation after a 50-item trial (Crocoblock, n.d.).
| Tool | Typical Price | What’s included |
|---|---|---|
| WP AI Writer | $29–$499/mo | Credit-based, 300–10,000 credits/mo, API cost billed separately |
| eesel AI | ~$99/mo | Flat rate for roughly 50 full posts, no separate API key |
| AIOSEO (AI add-on) | from $49.50/yr | SEO-plugin feature add-on, not a standalone writer |
| Divi AI | $18–$24/mo | Unlimited text/image generation inside the Divi builder |
| Edysor | $29–$199/mo | Credit-based (30–300 credits/mo), generation and image cost built in, no separate API key |

The Hidden Costs a Sticker Price Doesn’t Show
The number on the pricing page is rarely the number you actually pay per post. A few costs tend to hide below the fold:
- Your own API key. Tools that advertise a low base price sometimes require you to connect and pay for your own OpenAI, Anthropic, or Gemini account separately. WP AI Writer’s own listing flags this directly: none of its tiers include API costs (Capterra, 2026). That can turn a $29 plan into a $60 or $80 real monthly cost depending on usage.
- Image generation. Featured images and inline graphics are often capped lower than text generation, or priced as an add-on entirely.
- Editing time. A tool that only checks grammar still needs a human pass for accuracy, brand voice, and compliance. That time costs money, even if the software doesn’t charge for it directly.
- Regeneration. Credit-based plans charge again every time you regenerate a section that missed the mark, which is where “cheap” plans can quietly become expensive ones.
A quick gut check
Before comparing two tools on price alone, ask what happens to the total if you have to regenerate 20% of your posts, add your own API costs, and spend 15 minutes editing each draft. That adjusted number is closer to the real per-post cost than the plan price alone.
Where Edysor Fits
Edysor’s own pricing starts at $29 a month, which puts it right at the entry end of the range above, but the credit structure is what determines the real per-post cost.
The Starter plan includes 30 credits a month, covers one site, and generates posts between 3,000 and 4,000 words with all 24 content formats, compliance guardrails, and two images per post included.
Growth, at $79 a month, is built for agencies running multiple client blogs: 100 credits, five sites with a separate industry profile for each, internal linking, FAQ schema, and Yoast integration. Agency, at $199 a month, covers 300 credits, unlimited sites and profiles, and extra credits at $0.50 each if you go over.
What’s notable against the hidden-cost list above is what’s already folded into every tier: generation, images, and a compliance pass are all included in the credit price, so there’s no separate API key to fund on top of the subscription. That directly addresses the API-cost gap that inflates the real price of tools like WP AI Writer, where the listing explicitly excludes model usage from every plan (Capterra, 2026).
The pipeline also runs a compliance and “reads human” pass on generated drafts before they’re held for review, which is the kind of post-processing step that otherwise shows up as unpaid editing time on cheaper, generation-only tools.
You can see how that fits into the full content pipeline and what’s covered by compliance checks on the site.

FAQs
What’s a realistic monthly budget for an AI blog writer plugin?
Based on current published pricing, expect $30 to $100 a month for a small blog publishing a handful of posts weekly, and $100 to $500 a month for agency-scale volume. Where you land depends on whether the plan includes model usage and images, or bills those separately.
Is a cheaper AI blog writer plugin actually a worse deal?
Not necessarily, but it’s worth checking what’s excluded. A $24-a-month plan that bundles everything can cost less per post than a $99-a-month plan that bills API usage and images separately. Compare what’s included, not just the sticker price.
What is Edysor’s pricing?
Edysor starts at $29 a month for the Starter plan (30 credits, 1 site), $79 a month for Growth (100 credits, 5 sites), and $199 a month for Agency (300 credits, unlimited sites, extra credits at $0.50 each). Every tier includes generation, images, and compliance checks in the credit price, with no separate API account required. You can get started directly on any plan.
The Real Question Isn’t the Price, It’s What’s Inside It
Two AI blog writers can list the same monthly number and cost completely different amounts per finished post once you factor in API access, image generation, and editing time. The cheapest plan on paper isn’t always the cheapest one to actually run.
Edysor starts at $29 a month, with generation and image costs bundled into every credit-based tier from Starter through Agency. If you’re evaluating AI blog writers for WordPress and want pricing that doesn’t hide a second bill, you can get started at edysor.com.
