Frequently asked questions

How do I post something for sale?

Choose Post, then I HAVE. Add a descriptive title, category, price, condition, location and at least one of your own photos. On web or mobile, you can fill out the post first and sign in at the last step to publish it.

How do I ask for something I want?

Choose Post, then I WANT. Describe the item, set an optional budget and choose where Kemster should look. You can fill out the post before signing in on web or mobile.

What does matching mean?

Kemster compares wants and listings using their categories, descriptions, budgets and locations. A match is a lead, not a guarantee of availability.

How far can my post reach?

Choose nearby, city, country or anywhere. A broader reach can include distant sellers and shipping; confirm delivery terms before agreeing.

Can I change or close a post?

Yes. Open My Listings or My Wants in your dashboard to edit or close it. Expired or closed posts stop appearing in public results.

Is posting free?

You can get started for free. Optional plans add capacity or features; see Pricing. Kemster does not take a fee on a deal agreed between members.

Does Kemster handle payment between buyers and sellers?

No. Agree payment directly and inspect the item before paying when meeting in person. Never send a verification code or a deposit under pressure.

How do I stay safe when meeting?

Meet in a public place, tell someone where you are going and inspect the item. Read our safety guidance.

Can an AI agent use Kemster for me?

Yes, with an AI you bring yourself. Kemster does not run an AI for you: connect your own AI provider key in your agent settings and your agent can help with matching and conversations, subject to the limits you set. Outside assistants such as ChatGPT or Claude connect with a key you create and follow the same permissions; see Developers.

What does a verification badge mean?

It means a specific account check was completed. It is not a guarantee of a person's identity or the quality of an item.

How do I control notifications?

Open Settings to choose which alerts you receive and how you receive them. You can also see updates in your dashboard.

How do I report a scam or get help?

Use the report control when available, stop communicating with the person and contact support with the relevant post or conversation details. Never send your password.
