Watermelon

Is Watermelon worth paying for?

For a business that answers the same questions every day across chat, email and WhatsApp, the Starter plan is usually worth testing: it puts one AI agent on every channel and hands harder conversations to a person in a shared inbox. For a site with only a handful of enquiries a month, the free plan may be all that's needed.

The agent learns from a website crawl, uploaded PDFs and Word files, and a product feed, and answers in over 100 languages. Actions let it fetch live data, such as an order's status, or hand over to a human. Reviewers on G2 most often praise how easy it is to use, the range of ways to train the agent and how quickly support replies. The usual complaints are that set-up takes time and know-how, that the bot sometimes gives a wrong answer or none at all, and that re-crawling a website to refresh its knowledge is slow.

How much does Watermelon cost in the UK?

Watermelon prices in euros only: Starter is €99 a month (€84 billed yearly), Advanced €199 (€169), and Business €399 (€339). Enterprise is priced on request.

Watermelon's terms say all prices exclude VAT and invoices are issued in euros, so a UK card is charged in euros and the sterling cost depends on the exchange rate and any card fees. Each plan includes one AI agent, one user and a monthly allowance of conversations: 250 on Starter, 500 on Advanced and 1,000 on Business. Extra agents, extra users and blocks of 250 conversations each cost €25 a month. A conversation is every message with one visitor inside a 96-hour window, and test messages count towards the allowance. When the allowance runs out, the agent pauses until the next renewal unless the plan is upgraded or topped up.

Watermelon vs Chatbase: which is better?

Watermelon suits teams that want the AI agent and a shared human inbox in one place, with WhatsApp, Instagram, Messenger and email included from the Starter plan and EU hosting by default. Chatbase is the better-known chatbot builder and is often chosen by teams that mainly want a website agent.

Other options in the same space include Weav, which builds support agents from help documentation, Heyy, which centres on WhatsApp and Instagram messaging, and Maple, which answers phone calls and takes orders for restaurants. Watermelon's own phone agent is still marked as beta.

Is Watermelon safe to use with customer data?

Watermelon states that it complies with GDPR, is ISO 27001 certified and encrypts data in transit and at rest. It says customer data is never used to train AI models and that it doesn't take part in OpenAI's or Google's data sharing programmes.

The platform runs on Google Cloud in Europe (europe-west1), with MongoDB and Pinecone as further subprocessors, and encryption keys are managed in Europe. Watermelon B.V. is based in Utrecht and its contracts fall under Dutch law. A trust centre, subprocessor list and data processing agreement are published for procurement checks, and compliance features such as GDPR deletion and exports sit on the Business plan.

How do you get Watermelon cheaper?

Yearly billing takes 15% off every paid plan, which the billing help page describes as two months free. That brings Starter from €99 to €84 a month.

• The free plan covers 50 conversations a month, website scraping, file uploads, the website widget and the agent inbox.
• Add-ons at €25 a month can be cheaper than moving up a plan when only a few more conversations or one more user are needed.
• Testing in the playground uses up conversations, so heavy testing on a paid plan eats into the allowance.

No student, start-up or non-profit discount is listed, and Watermelon doesn't give refunds for unused time.
