Tracking shows where you stand. Serpier also suggests what to do next, and does it once you approve.
- Navi, Serpier's AI agent, reads your website, SEO performance, AI visibility and link monitoring, and suggests what to do next, each with why it is there: for example ordering a placement from a shortlist of publishers to work on a keyword sitting just off page one, or fixing robots.txt, llms.txt, the sitemap or meta tags.
- You click Hand over to Navi or I'll do it myself.

Method and what each row means
We read each company's own website: its pricing page, docs, help center, terms and announcements. Review sites, directories and articles about a company are never a source. Every value links to its source, with the date we checked it. Serpier's facts follow the same rule and come from Serpier's own website.
Prices are per month and exclude VAT, in the currency the company publishes. A price in another currency is also shown in EUR, at the ECB reference rate of 26 October 2026. Some companies show other prices or currencies depending on where the visitor is, so the page says which visitor the prices were shown to.
The shared units use one plan for each company: the entry plan we name for it, shown in its box above. If we name none, we use the cheapest plan with a published price above zero that tracks prompts. Only plans sold by the month count, at the monthly billing price when there is one. When the entry plan is an add-on, its price includes the plan it needs, because an add-on cannot be bought alone. Price per tracked prompt a month is the price ÷ prompts. Price per 1,000 AI answers a month is the price ÷ (prompts × assistants × runs a month) × 1,000, where a daily run counts as 30 runs a month and a weekly run as 4.33. When an input is not published, the page says Not enough public data instead of guessing.
Each value in the table is one of these, or the number or words the company uses:
- Yes:
- the company's own pages say the product has it.
- No:
- the company's own pages say it is not offered, or a complete plan table leaves it out.
- Partly:
- offered with a limit, written next to the value.
- Not stated:
- we could not find it on the company's own pages. It does not mean No.
- Not public:
- the company does not publish it, for example a price behind Contact sales.
What each row means

- Checks links after they go live:
- Whether the product checks links or articles you placed on other websites after they go live: still online, indexed and unchanged.
- Task board and AI agent:
- Whether you can track the work in the product and hand tasks to an AI agent that does them, with your approval.
- Scheduled automations:
- Whether the product can run a task or report on a schedule you set, such as a weekly summary.
