Tilly vs Alli AI

Alli AI changes your site itself: it deploys technical SEO fixes across every page, speeds pages up and pre-renders them for AI crawlers, from $299 a month for up to 5 sites.

Pick Alli AI if you run several sites, or one big site with technical problems. Pick Tilly if your store needs to be found for what your customers search and nobody has time to write. Tilly reads your product pages, reviews and customer questions, picks the searches worth winning, writes the posts in your voice and publishes them to your Shopify blog. It writes the title, description and alt text fixes you apply with one click, and checks every week whether ChatGPT and other AI assistants recommend you, for $79 a month.

Alongside the site-wide changes it has a site speed optimizer, pre-rendering for AI crawlers, keyword tracking, a link builder and a weekly crawl with recommendations. The Business plan covers 5 sites, 5 team members, 500 keywords and 1,250 pages, and every plan starts with a 10-day free trial.

Each app’s cells come from its own Shopify listing or pricing page, linked beside the words. “Not listed” means we did not find it there, not that the app cannot do it. Tilly’s column is our own product.

Alli AI's facts are from its pricing page, which shows monthly and annual prices; we list both where published. Alli AI has no Shopify App Store listing we could read, so the rating rows are empty.

Alli AI's Business plan is $299 a month billed monthly, or $249 a month billed annually at $2,990, and covers 5 sites, 5 team members, 500 keywords and 1,250 pages. Agency is $599 a month billed monthly. Every plan starts with a 10-day free trial.

Tilly starts with 100 free credits and no card, then $49 a month for 500 credits. A blog post with its cover is 15 credits, and the SEO audit, with a written fix for each finding, is free. There is no per-site or per-page charge on a single store.

For a one-store Shopify brand, Alli AI's entry plan buys capacity for five sites. For an agency with five client sites, that same plan may be the cheaper option per site, which is exactly who it is priced for.

The last table prices the same store on both. Semrush and Alli AI do not write the posts: they research and fix, and the writing stays with you or a writer. Surfer helps you write and optimise; Enrich Labs and Tilly write the posts themselves. Surfer’s prices are billed yearly.

Here is what Alli AI does that we do not. source, checked 25 September 2026

• Changes at scale. Alli AI deploys technical, AEO, GEO and SEO optimisations across an entire website; Tilly writes fixes for you to approve and applies meta rewrites in batches, not site-wide automation.
• Pre-rendering for AI crawlers and a site speed optimiser, both of which Tilly does not offer.
• Built for teams and agencies: the Business plan includes 5 team members and 5 sites, and Agency adds API access and white-label snippet hosting.
• Keyword tracking, a link builder and a weekly crawl with recommendations come as standard; Tilly tracks only the posts it publishes and has no link building.

Tilly writes the content that ranks for your customers' questions. The SEO agent groups searches by what your personas ask, found in your reviews and store, and writes one post per question with links to the products that answer it.

It learns from your own results. Every night it reads what each email, ad, post and page change earned, keeps the patterns your numbers back up, and writes the next piece with them, so a winning ad angle can become an email subject line and a product-page headline. Alli AI works on the site's technical layer; Tilly learns which topics and words bring your buyers and writes the next post, email and ad with them. (How the loop works.)

Two more things sit in the same place: Tilly asks AI assistants the questions your buyers ask and shows whether they name your store or a competitor (more on AI search), and it keeps a record of every edit to your theme, products, pages and menus, so a change in sales can be read against what changed.

It publishes to Shopify properly. Each post goes to your Shopify blog with a cover image in your brand's style, meta title and description, internal links and article or FAQ schema, after you approve it. New posts are handed to the email calendar so your subscribers see them.

It is sized for one store. There is no per-site or per-page price, and the same credits pay for the email, ads and page-fix agents, which read the same brand profile as the SEO agent.

It explains before it changes anything. Each audit finding comes with the fix written out, so you see what will change on your store before it does.

Moving between the two is less a switch than a change of focus. If you drop Alli AI, remove its snippet from your theme first so nothing half-deployed remains, and note which pages it changed so you can check they still look right without it.

Run Tilly's free SEO audit on the store the same day. It lists missing or duplicate meta, missing schema, thin collections and broken links, each with a written fix, which covers much of the ground a store with one site needs.

If you keep Alli AI for technical work, Tilly can still write and publish posts on the same store; the two do not touch the same things.

Watch the store's Search Console data for a few weeks after either change. Technical fixes and new content show up on different timescales, and it helps to know which one moved the numbers.
