Eva vs Vambe: which one fits your business?

Eva is our product, so this page is not neutral by nature; that is why it is verifiable. Every Vambe fact comes from its public pages and its terms of 26 May 2026, was checked on 24 September 2026 and keeps its link. Vambe publishes in US dollars, so no conversion is implied here.

Vambe does guided implementation well: a month with its engineers, two weeks of building and two of supervised launch, plus modules Eva does not sell, such as campaign management with Vambe Ads ($497 USD per month) and after-sales with Vambe Service.

It does not publish whether Meta's per-message WhatsApp charge is included, or the scope of its guarantee. Its pricing page contradicts itself on the cost of the second month, and its terms disagree with it on minimum term and cancellation.

That question separates a useful agent from one you have to watch. Eva answers from your catalog and your knowledge base, and only with the fields you marked visible. When a value is not loaded, it says so and asks a person on your team for help, who receives the conversation with its full history.

Teaching it something new does not go through a ticket: you change the key information, the process or the restrictions, test it in draft and publish it when you are satisfied. Until you publish, what it answers in production does not change.

Vambe publishes safety rails «para que tu IA no invente» and automatic tests before and after each update. On Capterra it holds 4.9 out of 5 from 21 reviews (the link is in the table, row «Public reviews»); inside five-star reviews, some customers list as a con early «tropiezos con educar a la IA» (stumbles teaching the AI) or that it sometimes «mezcla info» (mixes information up).

These are individual reviews, not a measurement. No vendor publishes a measured error rate, and neither do we. What you can do is ask for a demo with ten real customer questions, including one whose answer is not in your information, and see what each one replies.

On the Standard card paid monthly, Vambe charges $600 USD in the first month, $300 USD in the second and $574 USD every month from the third. The twelve months add up to 6,640 dollars; the arithmetic is ours, on its published figures. Its page offers 25 percent off with annual billing.

That price includes 3,000 conversations a month: every 24-hour exchange with the assistant, on any channel. An additional conversation costs $0.40 USD. If your volume grows, Service Pro costs $873 USD per month with 4,000 conversations.

Eva publishes from $191 USD per month on an annual plan ($229 USD month to month) on Essential, with 5,000 credits and 5 users. The annual plan equals ten monthly payments covering twelve months. Assisted setup costs $579 USD once, half price with an annual plan.

The two units are not the same: Vambe counts 24-hour conversations and Eva counts agent replies. Ask both for the arithmetic on one real week of your messages.

Vambe's pricing page says: «Todos nuestros planes son mensuales y puedes cancelar cuando quieras sin penalizaciones» (every plan is monthly and you can cancel whenever you want without penalty). Its terms, updated on 26 May 2026, set an initial term of one year with automatic renewal.

To cancel, those terms ask for 30 days' written notice and payment of the current and the following period. They also say payments are non-refundable and implementation is not returned once started. A signed contract may say otherwise, and that one governs.

Outside Chile, the contract is with Vambe AI, Inc., a Delaware company whose address is left blank in the published document.

Eva is bought month to month or by the year; cancellation is scheduled from the billing page for the end of the paid period, with no partial refunds. Whoever you choose, ask in writing for the term, the cancellation notice and the export of your data before signing.

Five points stay open: whether the second month costs $300 USD or is free, since its plan card and its FAQ disagree; the scope of its two-month guarantee and its «ROI garantizado»; whether Meta's per-message charge is included; the real number of integrations, stated as both 50 and 150; and its security certifications, which we did not inspect.

From 1 October 2026 Meta also charges utility templates inside the 24-hour window, so that row weighs more than it used to.

Eva has limits too: there is no public signup or free trial; onboarding is assisted. Eva Pay settles by SPEI, not card. If any of that is essential, say so in the first message and we will tell you no right there.
