1. Getting started

Pick Monitor or Pro on the pricing page and press Start now. Sign up with your work email, confirm it from the email we send, and pay on Revolut’s secure page. Then a short set-up takes about five minutes:

• Your brand: name, website, market and industry. A website readiness check starts at once.
• Competitors: we suggest some; add, edit or remove them.
• Languages: the languages your customers ask in, and the language of your reports (English or Greek).
• Questions: a draft panel of real customer questions; edit, remove or add within your plan.
• Confirm: your first run starts. You see its progress, and we email you when results are ready.

2. Your plan and billing

Your account page shows your plan, what you have used this month, your invoices or receipts and the next renewal date. Every document is emailed to you as a PDF and can be downloaded at any time.

Invoice or receipt. At checkout you choose the document you need, and you can change it from your account page for future payments. An invoice (Τιμολόγιο) is for a company that books the expense or reclaims VAT: enter your legal company name exactly as registered, your VAT number (in Greece the 9-digit ΑΦΜ, required; elsewhere optional, such as DE123456789), your tax office (ΔΟΥ) and registered activity if you are in Greece, and your registered street address, postcode and city. A receipt (Απόδειξη) needs only a name and an email. VAT: Greek VAT (24%) is added for clients in Greece and for clients elsewhere in the EU without a valid VAT number. EU businesses with a valid VAT number (reverse charge) and clients outside the EU pay the price without VAT. Each form shows a live preview of how the document will read. Invoices and receipts are numbered in order, each series from 111 (INV-111, REC-111).

One payment, no automatic renewal. Each payment buys 1 month (or 12 months) of access from the payment date. Nothing renews by itself and nothing more is charged. Runs you have not used by the end of the period expire. See the subscription and refund policy.

3. Buying another month

Buy another month any time from your account page: it starts when your current period ends, so you lose nothing. To move to Pro, choose Pro when you buy. We email you 3 days before your access ends.

4. When your access ends

New runs stop. Your results stay available to export for 90 days, after which we delete the account data. Buy access again any time to start new runs.

5. Reading your results

Each run asks every question 3 times on each AI assistant in your plan, through its official API with web search on. You see how often you are named, your position against competitors, why AI picks you or a rival, the websites AI cites, and the fixes to make first. Every number links to the answers behind it, and each rate carries an interval, so you can tell a real change from noise.

6. Share of the AI answer

Share of the AI answer: of all the times AI assistants name a brand when answering your market's customer questions, the share that name yours. Measured on the same question panel every run, so it is comparable over time. It is your headline number, next to the AI Visibility Score from 0 to 100.

7. AI SEO checks

An AI SEO check reads one page of your website the way AI crawlers do and gives a score and fixes ready to paste. Monitor includes 1 a month and Pro 5 a month.

8. Team and connectors

Account admins invite colleagues from the app. Pro adds API keys for the REST API. Every plan can connect Shelf by Markapp to Claude or ChatGPT: see the connector guide.

9. Questions
