"Blog writing tools" covers two very different products. Editors and assistants (Grammarly, Hemingway) make your prose cleaner. Generators and autopilot platforms (Jasper, theStacc) write the article. Mixing them up is how you end up with a $300/mo tool stack you barely use.
We tested 10 tools across the full spectrum over 90 days. Here is the ranking by what each tool actually replaces — by skill level, budget, and whether your bottleneck is craft or volume.
You write well, want it cleaner: Grammarly + Hemingway (free). You want AI to help draft: Jasper ($49) or Notion AI ($10). You want SEO-tuned output: Surfer SEO ($89) or Frase ($45). You want articles published without writing: theStacc ($99/mo, 30 articles done).
Don't want to write — just want articles?
theStacc handles research, briefs, writing, optimisation, and publishing to WordPress / Webflow / Ghost. 30 SEO articles a month for $99 — no tool stack to learn.
The 4 categories of blog writing tools
Every "blog writing tool" falls in one of four buckets. Buy by the bucket you actually need, not the marketing pitch:
- Editors / grammar — Grammarly, Hemingway. Clean prose you already wrote.
- AI writing assistants — Jasper, Notion AI, Koala. Draft alongside you.
- SEO-aware writers — Surfer, Frase, Scalenut. Brief + write + score for ranking.
- Full autopilot platforms — theStacc. Research → write → publish without you in the loop.
The default advice is "Jasper + Surfer + Grammarly + WordPress." That is $200+/mo and 10 hours/week of glue work. If you don't have writers on payroll, an autopilot tool that handles the whole pipeline ends up cheaper and faster than buying four tools that each cover one step.

Frequently asked questions
It depends on what you need. For full autopilot from keyword research through publishing, theStacc ($99/mo for 30 articles). For content optimisation, Surfer SEO ($89/mo). For AI-assisted writing, Jasper ($49/mo). For free editing, Grammarly.
For starting out, yes. Google Docs + Grammarly + Hemingway + WordPress + Yoast gives you a functional stack at zero cost. The limitation is time — free tools require you to do everything manually. Most bloggers outgrow free tools when they need to publish more than 4 posts a month.
No. Millions of successful blog posts were written without AI. But AI tools change the economics. A 2,000-word post that takes 4 hours manually takes 30–60 minutes with an AI writing assistant. If your goal is publishing volume, AI tools are a multiplier.
A blog writing tool helps you create content: drafting, editing, formatting. An SEO tool helps that content rank: keyword research, content optimisation, SERP analysis. Some tools do both (Frase, Surfer SEO). The ideal setup includes at least one of each.
For most use cases, yes. AI writing tools and autopilot platforms produce content at $3–$9 per article vs $80–$250 from freelancers. For thought leadership and opinion pieces, human writers still have the edge — but for SEO-target content, AI tools match or beat freelance quality.
Businesses ranking on Google's first page publish 20–30 articles per month on average. But consistency matters more than volume. Publishing 8 articles per month consistently beats publishing 30 one month and 2 the next. Start with what you can sustain.
Different tools for different needs. Jasper + Surfer gives you AI writing assistance with content optimisation — you still do the work. theStacc does the work for you. Jasper + Surfer costs ~$138/month and requires 10+ hours/week. theStacc costs $99/month and requires zero hours.
