100% free tool
Free blog outline generator
Give it a topic and get a full heading tree — one H1, the H2s in reading order, and the H3s underneath. Copy it as markdown and start writing.
How it works
Three steps, no account
Step 1: Name the topic
A phrase or a keyword. The more specific it is, the more specific the outline.
Step 2: We build the argument
Define it, say why it matters, show how to do it, name what goes wrong, price it, and say how you would know it worked. That is the order a reader needs, and it is the same shape our own planner uses for an explainer.
Step 3: Copy it as markdown
Headings only — no invented statistics, no made-up sources. You fill in the substance, which is the part that has to be true.
Frequently asked questions
Why headings only?
Because a heading is structure and a paragraph is a claim. An outline generator that writes "The three biggest 2026 trends" has invented three facts you now have to go and disprove. The outline is the part that can be honest without research.
Will the outline pass an SEO check?
The hierarchy will: one H1 first, at least two H2s, no skipped levels. That is one of the hard rules our own article checker fails a draft on, and you can run the finished piece through it on this site.
Can I change the number of sections?
Not in the free tool. Delete the sections you do not need — an outline you cut down is easier to work with than one you have to argue up.
Is it different with a model configured?
Yes. With an API key the outline is written for your specific topic; without one it is a template with your subject in it, and the page says which one you got.

These tools do one step each. Rankli does the whole loop: it reads your site, plans a month of articles, writes them in your measured brand voice, checks each draft against fifteen on-page rules and publishes it to your CMS.
