Use Deberli in Claude and ChatGPT
Add Deberli to Claude or ChatGPT and ask who would buy what you sell. It answers with how many decision-makers fit, who they are and a few real examples, and gives you a link that opens Deberli with the search already set up.
What it does
Deberli adds one tool to your assistant, called estimate_audience. Give it your website or a sentence about what you sell and to whom, plus the country you sell in. It answers with:
- How many decision-makers fit your offer
- Who they are: roles, places, industries and company sizes
- Five real people who fit, with their names blurred
- The buying signals Deberli watches for in that market
- A link that opens Deberli with this search already set up
The tool only reads. It needs no login and never contacts anyone. An estimate takes 30 to 90 seconds.
Add it to Claude
- Open Claude and go to Settings, then Connectors.
- Choose to add a custom connector.
- Paste the address below and save.
- Start a new chat and ask who you could sell to.

- Create a connector with the same address and no authentication.
- Start a new chat and ask your question.
Things to ask
I run a done-for-you Google Ads agency for dental clinics in the UK. How many practices could I sell to?
Here is my website: acme.com. Who should I be prospecting?
We sell bookkeeping to restaurants in Texas. Who decides on that, and how many are there?
Je vends un logiciel de planning aux agences d'intérim en France. Combien de décideurs je peux cibler ?
Tengo una agencia de marketing en Ciudad de México. ¿A cuántos directores comerciales podría venderles?
What an answer looks like
This is a real run from October 3, 2026, for the dental clinic brief above.
4,377 decision-makers fit in the United Kingdom: practice owners, dentists, practice managers, dental practice managers and clinic managers at dental clinics. Three of the five examples it returned:
| Person | Title | Location |
|---|---|---|
| H•••• A. | Dentist | Chesham |
| T••• M. | Lead Dentist | Windsor |
| G••••• B. | Practice Manager | Bristol |
The signals Deberli watches for in this market:
- Practice owners ask for help increasing enquiries and bookings
- The clinic hires marketing staff or a digital marketing supplier
- Practice leaders engage with dental marketing and growth providers
The answer ends with a link. Sign up from it and your Deberli workspace opens on the same search, with everyone unblurred and ready for you to review.
Limits and privacy
- Five estimates per person per day.
- Names are blurred and company names are left out until you sign up.
- Deberli keeps the brief or website you sent, a one-way hash of your IP address for the daily limit, the estimate and the link. The link works for 30 days.
- Nobody in the estimate is contacted. The privacy policy has the details.
