"Cheap" on a pricing page and cheap in practice are different numbers. We reweighted the rubric toward effective monthly cost after the upsell, a free tier you can actually use, and whether the plan hides a credit reset — then ranked eight tools by what you really pay, and named the bait.
For a price-led list we reweighted toward the true number: effective monthly cost after the upsell, a genuinely usable free tier, and quality per dollar — not the banner price. See the full rubric →

Rytr
Cheapest real unlimited
Rytr wins the price question outright: $9 a month for unlimited words, with a free tier of about 10,000 characters to test first. Nothing else here gives you an unthrottled paid plan for so little, and the free plan is a real one, not a demo. It runs short on long-form structure and brand-voice depth — but if cheap is the brief, this is the answer.
Cheap on the way in — a free plan and a $16 Lite tier with SEO checks — which makes it a strong low-cost start. The catch, and the reason it is not first: Writesonic's real momentum is toward AI-search and higher-volume tiers that climb to $199 a month and beyond, so the cheap plan can feel deliberately thin. Fine value if you stay on Lite and ignore the nudges.
The best genuinely free plan here, and the cheapest paid step at $12 a member on annual billing — but note what you are buying. Grammarly polishes and rewrites rather than drafting from a brief, so it is unbeatable value if editing is the job and poor value if you expected it to write the blog post for you. Know which you need before you count it as cheap.
Capable and, on Pro, unlimited — but not cheap, and the "free" plan is the tell. At 2,000 words a month it is a taster designed to push you to the $49 Pro tier, where the real product lives; there is no gentle middle step. Excellent tool, wrong list. If your budget tops out low, the jump from free to $49 is a cliff, not a ramp.
Frase is a strong SEO research-and-briefs tool, but on a price-led list it is mid-pack: $39 a month to start and no free plan, only a seven-day trial. You are paying for the research workflow, not raw cheap words. Worth it if ranking content is your aim; overpriced if all you wanted was a budget drafting tool.
Anyword's headline is $39 a user per month on annual billing, but the real cost climbs fast: extra seats are roughly $49–$59 each, and its data-driven predictions live on a $99 tier. For a solo user it is a pricey way to get words; its value is in ad performance, not in being cheap. On a budget list it lands low for the money.
At $79 a month on annual billing, Surfer is the priciest entry here, and deliberately so — it is an SEO optimization platform, not a budget word generator. For serious content teams that is fair value; for anyone chasing the cheapest way to produce copy it is simply the wrong category. Included only to be clear about where it sits on price.
Jasper is the strongest writer in the wider category, but on a price-led list it is last on purpose: $49 a month to start, no free plan, and word credits on the entry Creator tier. You pay for output quality and brand voice, not for being cheap. If budget is the whole point, Jasper is the tool you graduate to later, not the one you start with.

The verdict
Pay for the plan you will run, not the banner
If cheap is the whole brief, Rytr is the pick: $9 a month for unlimited words and a free tier that is a real free tier, not a countdown to an upgrade. Want a genuine free option for editing? Grammarly. Want cheap SEO drafting? Writesonic's Lite at $16 — as long as you ignore the push toward its $199 tiers. Everything from Copy.ai down is a fine tool priced for a different buyer than the one reading this page.
The bait to name out loud: a low headline price is not always where the product lives. Writesonic's $16 entry sits under tiers that reach $199+, and Copy.ai's "free" plan is a 2,000-word demo that forces a $49 jump with nothing in between. The true-free option worth starting on is Rytr's; the honest cheapest paid plan is Rytr's $9. Price the tier you will actually use for a month of real work — that number, not the banner, is the cost.
What is the cheapest AI writing software that is actually good?
Rytr. Its Saver plan is $9/month for unlimited words, which is the lowest real price for a credible writer that will not throttle you mid-draft, and its free tier gives you about 10,000 characters a month across every use case to test first. Writesonic’s Lite at $16/month and Grammarly Pro at $12/member (annual) are the next steps up. Below that, “free” usually means a demo, not a plan you can run a business on.
Which AI writer has the best genuinely free plan?
For drafting, Rytr’s free tier is the most usable — roughly 10,000 characters a month with full access to its use cases and tones, enough to actually try the tool. For editing rather than generating, Grammarly’s free plan is excellent and open-ended. Be wary of free tiers capped at a couple thousand words, like Copy.ai’s: they are demos designed to push you to a paid plan, not a free option you can live on.
What is the bait-and-switch to watch for on cheap AI writers?
Two patterns. The first is a low headline price that is not where the real product lives — Writesonic starts at $16/month, but its newer AI-search and higher-volume features push toward tiers costing $199/month and up, so the cheap plan can feel deliberately thin. The second is credit or word resets: a plan that looks unlimited until you hit a monthly cap and either wait or upgrade. Read what resets, and price the tier you will actually need, not the one on the banner.
Is a $9 tool good enough, or should I pay more?
For short-form work — social posts, product blurbs, emails, ad variations — a $9 Rytr plan is genuinely enough and paying more buys you little. You should step up when you need long-form drafting with structure, a trainable brand voice, or built-in SEO scoring; that is where Copy.ai, Jasper or Surfer earn their higher price. Buy the cheapest tool that clears your actual job, and no more — overpaying for features you never touch is its own trap.
