Diffee VS Evergreen AI

Evergreen AI's answer:

Most autopilot SEO tools stop at publish. Three things set Evergreen AI apart:

It keeps working after publishing. Every month it re-audits the pages you already have, catches the ones sliding down the rankings, and rewrites them. Ten of those enhancements ship alongside up to thirty new articles, so results compound instead of plateauing.

It declines unwinnable work. Before a word gets written, Evergreen AI scans the live SERP, harvests People Also Ask, and tears down up to six ranking pages. A competition-strength check skips a keyword entirely when the results are owned by domains you have no chance of beating, rather than filling a quota.

It came out of a working agency. Evergreen AI was built inside Tactycs and ran on real client sites before it was sold to anyone. It published under the founder's name to clients who would have fired him over slop, which is why the final filter strips the tells of machine writing: em dashes, "delve," "leverage," "robust."

Evergreen AI's answer:

Almost every tool in this category promises the same loop: analyze competitors, plan, write, publish. Evergreen AI is different in three places that only matter after you have signed up.

Depth, not a checkbox. Plenty of tools say they analyze your competitors. Evergreen AI scores every gap keyword on volume, difficulty, and how weakly the position is actually being held, filters it against what you genuinely sell, and de-duplicates by search intent so you never publish two articles chasing the same query. Then it re-runs as the landscape moves.

The work that happens after publishing. Most autopilot tools count new articles and stop there. Evergreen AI re-audits the pages you already have every month, catches the ones slipping, and rewrites them. Ten enhancements a month alongside up to thirty new articles. That is where compounding actually comes from, and it is the step agencies quietly skip too.

Accountability, not just volume. Evergreen AI was built inside Tactycs, a working marketing agency, and ran on real client sites before it was sold to anyone. That is why it will skip a keyword entirely when the SERP is owned by domains you cannot beat, rather than filling a quota, and why the final step strips the tells of machine writing.

Pricing is a flat $149 USD per site per month. No credits to buy, no per-article billing, no contract. It is not the cheapest option in the category, and it is about a tenth of a typical agency retainer.

Evergreen AI's answer:

Small businesses and lean marketing teams that know they should be publishing consistently and have no realistic way to do it by hand. The person signing up is usually the owner, or the one marketer covering SEO alongside six other jobs. No SEO specialist on staff, no writer on retainer, and a competitor who is quietly out-publishing them.

Concretely:

• Owner-operated service and trades businesses losing ground locally to a bigger rival
• Ecommerce stores competing against better-resourced brands
• Solo marketers and marketing managers where SEO is one duty among many
• Businesses weighing a $1,500 to $3,000 monthly agency retainer who want the output without the retainer
• Agencies and operators running content across several client sites

Who it is not for: anyone shopping for a keyword research or rank-tracking dashboard to poke at, and enterprises that need a full technical SEO audit suite. Evergreen AI does the work rather than reporting on it.

Evergreen AI's answer:

Evergreen AI started as an internal tool, not a product.

We run a marketing agency called Tactycs, and SEO delivery is expensive in very repetitive ways. Work out what a client's competitors rank for that the client does not. Decide what to write against those gaps. Write it. Publish it. Come back next month and do the whole thing again, because everything moved. It works, and almost all of it is mechanical.

So we built an engine to do it, and then we sat on it. It ran inside the agency across around 15 client accounts before anyone outside could touch it. Real businesses in different verticals, real competitors, real retainers, and our name on every article it published. Clients who get fed AI slop fire their agency, and they would be right to, so the quality bar had teeth from the first day. That constraint is the only reason this is built the way it is, down to the unglamorous parts: one filter exists purely to strip em dashes and words like "delve" and "leverage," because those are the tells that make a reader clock a page as machine-written and stop trusting it.

Our longest-running account on it went from an average position of 42 to 7 over twelve months. Organic clicks up 650 percent, impressions up 1,257 percent, 9.5 times the keywords ranking. Their Search Console export, not our dashboard. That is the point where productizing it stopped being a question.

Evergreen AI is that engine, opened up. Tactycs is still running and this does not replace it. Businesses that cannot justify an agency retainer run the engine themselves, and the ones who outgrow it and want people in the room know where to find us.
