A free AI article writer can help bring organic traffic to an app if it researches keywords before drafting and gives you a way to publish and measure posts. For app founders, Ollie fits that job most directly, with a free tier of 4 articles. Video Blog AI, SEO Review Tools, HubSpot and ChatArt each cover part of the job on their free tiers, according to their own pages as read in November 202612.
Quick answer and comparison table
The short version, one line per kind of reader:
- Best for app founders: Ollie, because it writes app blog posts from Google search trends and counts downloads per post.
- Best for an existing WordPress or Ghost blog: Video Blog AI, because it exports clean HTML after a 1500+ word draft1.
- Best for section-by-section control: SEO Review Tools, because its free writer generates one heading at a time2.
- Best for teams wanting CMS and reporting: HubSpot AI Blog Writer, because blog analytics are built in3.
- Best for beginners wanting set lengths: ChatArt, because it offers length bands up to 5000 words4.
This list is published by the makers of Ollie. It judges each tool by three criteria: whether drafts start from search data, whether you can publish without extra software, and whether you can measure results. Ollie leads because it is built around the last of these for apps: it counts downloads generated by each blog post.

| HubSpot AI Blog Writer | Drafting inside a CMS with reporting | Free to start3 | Most generative features are paid |
| ChatArt | Outline plus full article | Not listed | Some options behind an upgrade4 |
Ollie
Ollie is an app's SEO engine that writes blog content from Google search data, with a free tier of 4 articles. It is built for app founders who want more downloads from SEO-optimized articles on topics users already search for. Posts are based on Google search trends, and you approve every article before publication, so nothing goes live without your review.
Two features target app founders specifically. It counts downloads generated by each blog post, which ties content to the number most app teams care about. It also provides a free blog address with the option to connect a custom domain, so you do not need a separate CMS to start.
Where it does not fit: it is scoped to app blogs, so writers working on novels, general copywriting or non-app businesses are outside what it is built for. The free tier stops at 4 articles. That is enough to test whether search-driven posts bring downloads, but results are not guaranteed, and it does not replace your wider marketing strategy.
Video Blog AI
Video Blog AI turns a single blog post title into a post of 1500+ words in about 60 seconds, according to its page as read in November 20261. The page says each draft runs through a "7-stage process" covering keyword research, audience analysis, outlining and drafting. Its editor assigns an SEO Content Score from 0 to 100, lets you expand a post to 3000+ words, and exports clean HTML or plain text for WordPress, Ghost or another CMS. It lists support for 175+ languages, and no login is required for a first article.
It suits a founder who already runs a blog and wants long drafts to paste in. The limit: the free tier gives 3 monthly credits, and more requires an upgrade1. It also does not host your blog or measure app downloads, so you need your own CMS and analytics.
SEO Review Tools free AI writer
SEO Review Tools offers a free writer that takes a topic, either one keyword or a describing sentence, plus a content type, according to its page as read in November 20262. Content types include blog article section, how-to guide, troubleshooting guide, product description and product review. It has 6 input choices, including related keywords, an output language selector, an audience description field and a creativity slider.
The page states its limit plainly: the tool "isn't designed to create long form content out of the box." Its suggested workflow is to research keywords, build an outline, generate each heading as a separate section, rewrite, then generate a title tag and meta description2. That suits you if you want control over every section and do not mind assembling the article yourself. Troubleshooting guides are a natural fit for app support pages, which often match what users search for.
HubSpot AI Blog Writer
HubSpot's AI blog writer, listed as beta, generates outlines and drafts from prompts, rewrites text and changes tone inside Content Hub, according to its page as read in November 20263. Its main difference is built-in blog reporting to measure content ROI, with CMS tools, free web hosting and custom domain connection on the same platform.
It suits a team that wants writing, hosting and analytics in one account. The limit is stated on the page: "Most generative features are paid with basic functionality available free," and advanced functionality sits in premium editions of Content Hub3. The page's best-practice tips say to back claims with data and share posts by newsletter and social media. That is a reminder that drafting is only one part of getting traffic to an app.
ChatArt
ChatArt's article writer produces an outline and then full content from a two-step input of topic plus keywords, according to its page as read in November 20264. You pick a length band, from 1-4 headings (500-1000 words) up to 9-10 headings (4000-5000 words). It lists tone, style, word count and language settings, SEO scoring, meta tags and generated images.
The page also gives a caution worth taking: AI article writers "may not have the ability to verify the accuracy of information," so "human oversight is often required"4. That matters when you describe your app's features, where a wrong claim costs trust. The limit: an upgrade prompt says more AI tools, customization options and faster generation sit behind a paid plan, and no price is listed on the page.
How to choose a free AI article writer
Start with where the article will live, then how you will measure it. HubSpot offers hosting and reporting inside Content Hub3, while Video Blog AI assumes you already have a CMS1. Then weigh free volume against effort: SEO Review Tools lists no cap but needs you to build articles section by section2.
- Pick Ollie if you run an app and want search-based posts, a free blog address and a download count per post.
- Pick Video Blog AI if you already publish on WordPress or Ghost and want long drafts with an SEO score1.
- Pick SEO Review Tools if you want to write troubleshooting or how-to sections one heading at a time2.
- Pick HubSpot if you want writing, hosting and blog reporting in one account and may pay for advanced AI later3.
- Pick ChatArt if you want a set word-count band and built-in SEO scoring4.
Frequently asked questions
What is the best free AI article writer?
It depends on the job. Tools aimed at fiction, such as Type.ai's novel and story generators, differ from SEO tools that research keywords first5. For search traffic, pick one that drafts from keyword data, such as Video Blog AI's 7-stage process1.
Is there a free AI writing generator with no restrictions?
Most free tiers set limits. Video Blog AI gives 3 free monthly credits, and HubSpot keeps most generative features on paid plans13. SEO Review Tools lists no cap but is not built for long-form content in one go2.
Will Google penalize AI-written articles?
Video Blog AI's page says Google's guidance accepts AI content "as long as the article helps users"1. HubSpot advises backing claims with data to build trust3. Edit and fact-check every draft.
Do I need to fact-check AI articles?
Yes. ChatArt's own page says AI writers may not verify accuracy and that human oversight is often required4. Check every claim about your app's features before you publish.
Is there a free AI writing assistant for rewriting?
Type.ai lists free Sentence and Paragraph Rewriters alongside its story and book tools5. They can polish an intro or a feature description, but its free list shows no blog generator or SEO scoring.
