Which is cheaper, HeyKiko or SiteGPT?
At 1,000 AI replies a month HeyKiko costs $29 and SiteGPT $59; at 12,000 it's $199 against $429. On SiteGPT, add $59 a month for WhatsApp. Here is the cheapest way to get each volume on each.
| AI replies a month | HeyKiko | SiteGPT |
|---|---|---|
| 1,000 | $29Starter (2,000 credits) | $59Starter (4,000 GPT-4.1 mini messages included)$118 with WhatsApp |
| 4,000 | $119Growth (10,000 credits) | $59Starter (4,000 GPT-4.1 mini messages included)$118 with WhatsApp |
| 12,000 | $199Pro (20,000 credits) | $429Scale (40,000 GPT-4.1 mini messages included)$488 with WhatsApp |
Monthly billing, before tax, for the cheapest plan that covers that many AI replies. SiteGPT counts messages on GPT-4.1 mini; a GPT-4.1 message counts as ten. Its WhatsApp add-on is $59 a month per number ($39 billed yearly), shown as the second price. On HeyKiko a normal reply uses one credit on the standard model and more on bigger models, and Meta bills WhatsApp messages separately. HeyKiko prices are our live plans in USD; see pricing for every limit.
Where do their answers come from?
Both learn from your website and files and can show the sources behind an answer. SiteGPT connects to more places: sitemaps, YouTube, Notion, Google Drive, Dropbox, OneDrive, Box and GitHub. It runs on GPT-4.1 and GPT-4.1 mini.
HeyKiko reads your website, files, written notes and a product catalogue, and can look up live data in a read-only database you connect. When your knowledge doesn't cover a question, Kiko says so and can hand the customer to a person.
Which channels do HeyKiko and SiteGPT work on?
SiteGPT is website-first. WhatsApp and AI email support are paid add-ons, Slack, Messenger, Google Chat, Crisp, Freshdesk Messaging and Zoho SalesIQ come with its Growth plan, and Zendesk Messaging with Scale. Its docs say it doesn't support Instagram, and we found no Telegram, SMS or voice.
HeyKiko works on your website, WhatsApp and Telegram on every plan, and answers WhatsApp voice calls on plans with calls. It doesn't offer Slack, Messenger, Instagram or email as chat channels.
Can a person take over the conversation?
Yes, in both, on every plan. SiteGPT lets your team reply to visitors, and adds an iPhone app from its Growth plan (iOS 18 or later; there's no Android app).
HeyKiko's shared inbox runs in the browser and holds website, WhatsApp and Telegram chats in one list. Replying pauses the AI for that customer, a customer who asks for a person is handed over automatically, and you can send every hand-off to one person.
Can they book appointments, open cases or send campaigns?
SiteGPT focuses on answering questions; we didn't find appointment booking, case management or campaigns on its pages. It offers webhooks and an API if you want to build your own.
HeyKiko books into Google Calendar itself, opens cases with approvals for refunds and requests (Growth and up), sends WhatsApp campaigns on every plan and email campaigns (Pro and up), and replies to a campaign go straight back to the agent.
Can either answer phone calls?
HeyKiko answers voice calls to your WhatsApp Business number (Pro and up), books during the call and flags calls for your team to follow up on WhatsApp. It doesn't answer regular phone lines. We found no voice or phone calling on SiteGPT.
How do they handle data and security?
SiteGPT states SOC 2 Type II and GDPR compliance, offers a HIPAA BAA on Enterprise, and says its data is mostly hosted in the US, without EU-only hosting. If a SOC 2 report is a requirement, SiteGPT offers one today.
HeyKiko lets you decide which knowledge each group of signed-in customers can use, erase one customer's details and chats, set how long conversations are kept, and place a legal hold when everything must be kept.

How we compared
We read SiteGPT's own pricing page, product pages and docs on 4 November 2026. HeyKiko's column comes from our live plans. Prices are monthly billing in USD before tax unless shown otherwise; both products bill differently per AI model, and both pass WhatsApp message fees through from Meta. If something here is out of date, tell us and we'll fix it.
