I Tested Free AI Blog Post Generators – Here's Why Writely Won

What I looked for in an AI blog post generator (free)

I’ve tested a handful of free AI writing tools over the past few months, mostly because I needed to draft blog posts faster without paying for another subscription. The promise of a decent ai blog post generator free is tempting, but most fall short once you actually try to produce something publishable. I spent a few weeks with Writely to see if it could do the job without the usual friction.

Here’s what I looked for, and where Writely landed on each point. Think of this as a checklist if you’re also hunting for a best free ai writing tool that doesn’t waste your time.

1. Can it actually finish a post from a rough idea?

Many free tools give you a paragraph or two and then stop. Writely lets you feed in a loose concept and keeps going. I tested it with a half-baked thought about “why composting is harder than people think.” The first draft was about 600 words – not perfect, but it had a clear structure: problem, common mistakes, a workaround. I didn’t have to nudge it much. That felt more complete than what I got from other free generators that just spit out an intro and then dried up.

2. How much editing did I really need to do?

Here’s the tradeoff: Writely produces drafts that are readable but not ready to copy-paste. I had to rework the tone – it tends to default to slightly formal SEO-speak, so for a personal blog I had to loosen it up. But the core ideas and the flow were there. For a content-heavy post with subheadings, I saved maybe 40 minutes per draft. That’s realistic, not “magically writes the whole thing.” If you expect zero editing, you’ll be disappointed. But if you’re okay polishing, it’s a solid free ai writing tool 2026 candidate.

3. Does it help with SEO without being spammy?

A lot of free generators jam keywords in awkwardly. Writely handled my secondary keywords (like “composting mistakes” and “beginner guide”) without making the text sound robotic. I ran one post through a readability checker – it scored decently. That said, I noticed it sometimes repeats similar phrases in longer sections. You’ll want to scan for that. But for a free tool, the SEO awareness is above average.

4. Is the free tier actually useful, or just a teaser?

This is the main reason I’m writing this roundup. Many “free” tools limit you to 2,000 words a month or force a watermark. Writely gave me enough credits to write three full blog posts (around 1,500–2,000 words each) before I hit a wall. That’s enough to test it seriously. The limitation is that you can’t save unlimited drafts in the free version – you have to export or copy what you like. Mild friction, but not a dealbreaker.

5. What about organizing ideas?

I appreciated that Writely isn’t just a text box. It has a simple project board where you can group outlines, drafts, and final versions. I used it to plan a series on home renovation – the ability to keep related posts together mattered more than I expected. Most free tools just give you a single editor and nothing else. This felt a notch more thoughtful.

6. One limitation I can’t ignore

The free version doesn’t support all export formats. I wanted to export as Markdown for my static site, but I had to copy-paste and reformat. Not a huge issue, but if you’re used to one-click exports, you’ll feel it. Also, the tone customization (professional vs. casual) is there but finicky – sometimes changing the setting didn’t noticeably shift the output. It’s not unreliable, just inconsistent.

Who should consider this AI blog post generator free option?

• Bloggers who outline first and want someone to flesh out the details.
• Anyone testing Writely as a potential upgrade later – the free tier is genuinely useful for evaluation.
• People writing in niches where SEO matters but not hyper‑competitively.

If you need heavily researched, fact‑checked posts, no free tool will replace your own work. But for first drafts, idea expansion, and overcoming blank‑page paralysis, this one holds up.

I’m not ready to call it the best free ai writing tool for everyone – but for blog posts specifically, it’s the one I kept coming back to. I’ll probably keep using the free tier for shorter pieces and consider the paid version when my output grows. That feels like a fair verdict.
