SearchAtlas OTTO and Tedrix both promise to take SEO work off your hands, and the two products genuinely differ in philosophy. OTTO leans toward autopilot: find many issues, fix them at scale, ask little. Tedrix leans the other way: fewer changes, each one approved by you, each one measured afterward. Which is right depends on what you are protecting.

The technical difference that gets too little attention
OTTO applies most of its on-page fixes through a JavaScript snippet you install on the site: the corrections are injected into the page when it loads in a browser. That is what makes broad automation possible, and to be fair, it is a clever mechanism. But it has a consequence worth understanding before you choose: the fixes exist in the browser, not in your site's own HTML. AI assistants like ChatGPT and Perplexity do not run JavaScript when they read the web, so injected fixes are invisible to them. And if the snippet is ever removed or fails to load, every fix disappears with it.
Tedrix applies the approved change into WordPress itself, through a plugin that writes the real title, meta description and SEO plugin fields, saved as a native revision. The change is in your site's HTML for every reader, human or AI, and it survives no matter which tools you use later. One click reverts it.
Autopilot versus approval
OTTO can run with approvals switched on, but its pitch is scale: hundreds of fixes across a large site with little human time. Tedrix is approval-first by design: nothing changes on your site without your yes, and drafts are only written for pages that are measurably slipping. If you run a huge site with thousands of small technical issues, OTTO's breadth is a real argument. If you run a business on twenty pages that must not break, a tool that changes two of them for a clear reason, with your approval and an undo button, is the safer shape.
What only one of them can show you
Tedrix returns to every applied fix about four weeks later and records what happened to the page's clicks and position. Over time that builds a per-site record of what actually worked, which is also what its drafts learn from. When a tool applies hundreds of changes at once, nobody can honestly attribute the outcome to any one of them.
