A personal CRM to organize your contacts and close ones

The simplest way to organize your contacts is to sort the people who matter by how close you are to them, not alphabetically. That's what Serkle does: a free, private personal CRM where you place each person on a circle around you (family, friends, work, from closest to furthest), with a note to remember who they are.

Your phone holds hundreds of numbers, but it doesn't tell you who really matters or where you met someone. Serkle does: a personal CRM built for the people in your life, not for sales leads.

How Serkle organizes your contacts

1. A circle around you. You in the middle, five circles around you: the 1st for your closest people, the 5th for the furthest. You see who matters at a glance.
2. One category per person. You name it: "Family", "College", "Thursday football", "Work"… Each category has its color and its place on the circle.
3. The relationship. Family, friend or work: hover over someone and everyone with the same relationship lights up.
4. A private note. Their job, where you met, their kids' names… Search reads it too: type "dentist" or "Lisbon" and find the right person.
5. Everyone, even without the app. Add your grandmother or your plumber by hand. If they join Serkle one day, their card links to their account, with their consent.

Your circle is private: nobody sees who you added, in which circle or category. Even the person you added never sees your note.

Manage your serkle by talking to ChatGPT or Claude

Serkle has an official connector (MCP) for ChatGPT and Claude. Once it's connected, just ask your AI: "Add Leah to my serkle, 2nd circle, category College, note: met in Lisbon", "Who in my serkle is a dentist?" or "Move Karim to my closest circle". It updates your serkle for you.

• You choose what it may do: read your serkle, read your notes, search, add, write.
• Nothing happens without you: it asks before adding someone or sending a message.
• Cut access any time, in Serkle's settings.

Serkle vs a contacts app, a spreadsheet or a sales CRM

Who it's for

• You have hundreds of contacts and no longer know who's who.
• You have a busy life and want to keep the people who matter in sight.
• You just moved and want to stay close to the people you left, while meeting new people where you live.
• You want a simple personal CRM, without a spreadsheet to fill in.

Frequently asked questions

What's the best personal CRM app?

For the people in your life rather than your sales pipeline, Serkle: a visual, private personal CRM where you place each person on a circle by how close you are, with a category, a relationship and a private note. It's free up to 100 people, with no ads, and it also helps you meet people who share your interests.

How do I keep track of all the people in my life?

Start with the people who matter, not your whole address book. On Serkle, add each person with their circle (from 1, closest, to 5, furthest), their relationship (family, friend, work) and a category of your own. A few minutes a day, and your circle takes shape.

Is there an app to organize friends and family by how close I am to them?

Yes: that's exactly what Serkle's circle does. You're in the middle, and each person sits in one of five circles around you, from your closest people to those further away. You can filter the circle by category or relationship in one click.

Is there a free alternative to Clay or Dex?

Serkle is free up to 100 people, with no ads; Serkle+ ($24 a year) removes the limit. Where tools like Clay or Dex focus on your professional network, Serkle organizes your close ones by how close you are, keeps everything private, and also helps you meet new people who share your interests.

How do I remember to stay in touch with friends?

Keep them in sight: on Serkle, your closest people sit in the first circles, in the middle of your screen, and a note reminds you what matters to each of them. Gentle reminders to check in are coming soon, always as a question, never a reproach.

Are my contacts private?

Yes. Your circle, categories, notes and the numbers you save are visible to you only. Serkle never contacts the people you add, never sells data and shows no ads.

Does Serkle work with ChatGPT or Claude?

Yes. Serkle has an official MCP server: with your consent, your AI can read your serkle, find someone by your note, search for people and add them, from the conversation. You choose what it may do and can cut access at any time.
