Free AEO tools, compared by the loop: which ones fix, not just score you (2026)

Questions this guide answers

• Is there a free AEO tool that fixes my content, not just scores it?
• Which free AI visibility tool gives recommendations I can actually ship?
• Are there any free AEO tools that close the loop?
• Do free AEO tools generate the schema or fix for me?
• What is the best free AEO tool with execution, not just a dashboard?
• Which free GEO tool tells me exactly what to change?

Direct answer

There are plenty of free ways to find out how visible your brand is in AI answers in 2026. There is almost no free way to do anything about it. That gap is what this guide is about.

Sort the free options by the job and they fall into a four-step loop: Measure (where do I stand in AI answers?) → Diagnose (what specifically is wrong?) → Execute (give me the exact fix to ship) → Verify (re-test the same prompts to prove the fix worked). We surveyed 16 free offerings against those four steps. The result is lopsided: every free tool measures, some diagnose, and — with one honest exception we name below — none of them executes. They hand you a score and a gap list and stop.

Disclosure up front: SolCrys publishes this guide and our own free tier is one of the tools compared. We are not a neutral source. We have written it the way we wish other "free tools" lists were written — naming who is free-forever, who is a one-time lead-gen scan, and who is a trial with a meter running — and honest about our own caveats too (our free tier can hand you the fix but cannot yet fully re-verify it within the free quota; see below). Pricing and coverage are from each vendor's public 2026 pages and dated third-party reviews; treat them as orientation, not quotes.

• The whole free category stops at the scoreboard. Free-forever trackers (Trakkr), one-shot graders (HubSpot, Ahrefs, Semrush, Mangools, Rankscale, Knowatoa, Goodie), and free trials (Peec, Otterly, Scrunch, Nightwatch, Am I on AI) all top out at Measure or Measure + Diagnose.
• Best free measurement: Trakkr — the one genuinely free-forever tracker (1 brand, ~8 engines, daily). If all you want is a free line that keeps moving, start there.
• The one tool that reaches Execute on a free tier is SolCrys — the same free audit that scores your page hands you the concrete change to ship (the JSON-LD block, the heading rewrite), tied to the prompt set you were scored on.
• Verify is where everyone — including us, on free — runs out of road. A re-test costs another measurement credit, so a true free re-verify loop effectively does not exist anywhere yet. We are honest about that below.

The one distinction that decides everything: a score is not a fix

Most "free AEO tool" lists rank tools by how good the number is — how many engines, how fresh, how pretty the dashboard. That is the wrong axis, because almost all of them live at the same step of the loop. They are scoreboards. A scoreboard tells you that you are losing 1–0. It does not tell you to swap your striker.

The expensive, skilled, slow part of AEO is never the measurement. It is the work after: figuring out the specific change that will move a specific answer, writing it, shipping it, and proving it moved. So the only distinction that changes your week is whether the free tool does any of that work for you, or hands the score back and wishes you luck.

That single question — score, or fix? — is what the comparison below sorts on.

Every free AEO option, mapped to the loop

Stages are scored for the free offering only. "Free-forever" = a perpetual free plan. "Grader" = a free one-time scan or score. "Trial" = a time-boxed full product. Execute = the tool generates the artifact you ship (schema, rewrite, FAQ), not a generic tip.

"But Writesonic's free LLM Optimizer rewrites my text" — the one honest counter, handled

It does, and it is worth naming so this page is trustworthy rather than convenient. Writesonic ships two free standalone tools: an AI Search Grader (a score) and an LLM Optimizer that will rewrite a snippet to add quotes and citations. The rewrite is real "execution."

But it is not loop execution, and the difference is the whole point. The LLM Optimizer is a disconnected text box. It does not know which buyer prompt you are losing, it is not fed by an audit of your live page, it does not emit the JSON-LD a crawler needs, and nothing ties the rewrite back to a re-test of the prompt set that scored you. Writesonic does close the full loop — measure, diagnose, execute, verify — but only on its paid GEO tiers (from ~$199/mo), not in the free tools. So on a free basis it lands the same place as everyone else: a score on one screen, a generic rewriter on another, and a manual leap in between.

That is the bar this comparison holds: does the free tool execute the fix that its own measurement told you to make? By that bar, the count is one.

Why the whole free category stops at the scoreboard

This is not an accident of any one vendor; it is the business model. A free AI-visibility score is the most efficient lead magnet in this category — it is cheap to run, it produces an alarming number ("you appear in 4% of answers"), and the alarm is what sells the paid plan. The recommendation engine, the content drafting, the schema generation, the re-test — the parts that cost real compute and reputation — are exactly what the paid tier is for. So the free experience is engineered to stop precisely at the moment you would want to act.

That logic is why "free AEO tool" so reliably means "free AEO grader." It is also why the one place a free tier crosses into Execute is worth a closer look.

What "reaches Execute on free" actually looks like

On the SolCrys free tier, you run a Content Audit on a page (one per month on free). The audit does not just score it — for each finding it surfaces, through the Action Hub, the specific remediation: the exact JSON-LD block to paste, the heading or meta rewrite, the FAQ to add, with the points each fix is worth. You promote a finding to a task and you are holding the change, not a suggestion to go make one. That is the step every other free tool leaves to you.

The honest boundary, stated plainly so we do not oversell our own column: free is ChatGPT-only and manual (it will not track Gemini, Perplexity, or Google AI surfaces — those are paid), it is one audit and one deep analysis a month, and the closing re-verify is rate-limited. The re-audit that proves your score recovered is built and shipped, but it spends another monthly audit credit — so on free you get one clean pass through measure → diagnose → execute, and the proof it worked arrives the next cycle or on a paid plan (Starter adds four audits a month). We would rather say that than pretend the free tier is the whole loop. It is not. It is the only free tier that gets you to the part that matters: the fix.
