This page is mostly a redirection, and it is more useful than an argument would be.
People search for MobileMonkey because they remember a Facebook Messenger and Instagram chatbot builder and want to know whether it is still the thing to buy. Reading the company's own site on 26 August 2026, here is what is publicly visible: the brand is Customers.ai, the home page headline describes turning Klaviyo into a profit machine with identity resolution, and the named products are X-Ray for first-party identity resolution, Alfred as an AI audience agent, Inboxer for email deliverability, a Meta CAPI server-side ads tracking product, and a Klaviyo grader. The login and signup links on that page still point at app.mobilemonkey.com, which is where the old name survives.
The pricing page, checked the same day, does not publish plan prices. It shows a calculator, points to a sales conversation, and states that pricing is based on total Klaviyo profiles — every profile in the account, including suppressed and unsubscribed ones — rather than active subscribers. A seven-day free trial is offered covering up to 500 visitor resolutions, with no card required.
Neither page, read that day, mentioned Instagram or Messenger chatbot automation.
If you came here for the Instagram half
Then you are shopping in a different category from the one Customers.ai currently markets, and the useful question is what you actually need that category to do.
Most people who ask for a chatbot want something narrower than a chatbot: the same four answers, sent quickly, in their own words, without them being awake.
PostEngage does one thing. It answers Instagram comments and DMs through the official Instagram Graph API. You connect an account through Meta's own OAuth screen — no password reaches us. An automation names a post, the keywords that should match with any-of or all-of logic, the negative keywords that should stop it, a public reply, a private reply, and whether the person gets captured into Leads. Advanced adds first-time senders only, quiet hours, and restricting the automation to specific posts. Two buttons finish it: Test on myself, then Go live.
What it does not do, stated so you do not have to find out later: no website chat widget, no email, no SMS, no ads tracking, no WhatsApp, Messenger or Telegram, no flow-builder canvas, no broadcasts, no sequences, no analytics product. Leads leave as CSV; there is no one-click CRM sync.
The pricing shape, since you are re-evaluating anyway
One credit is one AI-written reply. Replies sent from a template you wrote are free and unlimited, however many people receive them. Nothing is metered per contact, per follower or per conversation — which is worth noticing if you are coming from any tool priced on the size of a list, because a list-shaped meter charges you for reach while revenue comes from conversion.
Free tier: 100 credits, no card. Packs: ₹499 for 500 credits, ₹1,699 for 2,000, ₹4,499 for 6,000, or $6.99, $22.99 and $59.99.

Before anything sends
Ten checks run in a fixed order: kill switch, connection, takeover, window, dedupe, cooldown, quiet hours, rate budget, credits, content safety. The first failure stops the send and records its reason in Activity. Takeover is third, so the moment a human replies by hand the automation stands down. Running out of credits is a refusal like any other, and the fallback is your own template rather than silence.
Both windows are Instagram's, not ours: a comment is answerable for 7 days, a DM for 24 hours after that person's last message. Nobody on the official API sells an exemption.
Re-evaluating an old setup
There is a particular kind of afternoon that brings people to a page like this: an automation that has been quietly running for two years, a tool whose website no longer looks like the tool you bought, and a suspicion that nobody has read what it sends in a long time.
If that is you, do one thing before shopping at all. Open the last twenty replies your existing automation sent and read them end to end. Half the time the answer is not "switch tools" but "this template stopped being true in March". A tool cannot fix a sentence you no longer mean, and moving that sentence to a new vendor moves the problem with it.
Then, if you do shop, judge on the awkward moments rather than the feature grid: what happens when the same person triggers twice, when a comment lands at 2am, when you jump into the thread yourself, and whether the tool can show you a reply it decided not to send. That last one separates the category more cleanly than anything on a pricing page.
Where to go next
If your business is a Shopify store where email is the money and the missing piece is knowing who visited, Customers.ai is aimed squarely at you and we are not.
If the missing piece is that your Instagram comments go unanswered until lunchtime, start on the free tier — 100 credits, no card — and read getting started before you point anything at real people. The rest of the field, with the date each page was read, is on the comparisons index, and the two closest products to this one are ManyChat and Chatfuel.
