Which one, for whom

Pick Olark if

  • You want an AI chat agent at a flat monthly price with no usage meter.
  • Website chat is the only channel and simplicity beats features.
  • You want the AI in the seat price ($400/mo flat) rather than Brevo (Sendinblue)'s meter at Aura AI.
  • Time to the first reply is minutes here and an afternoon on Brevo (Sendinblue).

Pick Brevo (Sendinblue) if

  • You already send campaigns from Brevo and want the same contacts in the inbox.
  • Marketing automation matters as much as support.
  • Five people cost $70 a month less than on Olark ($75 against $145), before AI.
  • You need WhatsApp and Instagram in the price, which Olark does not include outright.

The third option: Sellio

  • You are two to ten people on Olark or Brevo (Sendinblue) who answer chat, messaging and email, and want to compare workspace pricing with $145 a month on Olark against $75 on Brevo (Sendinblue) for five people.
  • You want the AI bill known before the month starts: Olark folds AI ($400/mo flat) into the plan, Brevo (Sendinblue) meters AI (Aura AI) above the seats; Sellio includes a credit and lets you cap it.
  • You need Telegram and native Windows and macOS apps, which neither Olark nor Brevo (Sendinblue) includes.

What two, five and ten people pay

Olark on Live chat: $58, $145 and $290 a month for two, five and ten people, before AI. Brevo (Sendinblue): $75 a month for five (5 seats × about $15); it does not print a per-seat rate to extend to two or ten. Sellio: Free for two seats; Mini at $45 for five, $100 less than Olark and $30 less than Brevo (Sendinblue) for five people; Essentials at $95 for ten, the AI credit included. At ten people, Essentials at $95 is $195 under Olark.

Where the two agree, and where they split

Olark is a live chat software built around a simple chat box; Brevo (Sendinblue) is a marketing platform with a chat inbox built around email campaigns. Only Brevo (Sendinblue) has a free plan (one seat, one channel); Olark offers a free trial. Olark and Brevo (Sendinblue) both include website chat in the price; only Brevo (Sendinblue) has WhatsApp and Instagram. Neither Olark nor Brevo (Sendinblue) includes email and Telegram outright. Olark folds AI ($400/mo flat) into the plan; Brevo (Sendinblue) meters AI (Aura AI) above the seats. Neither Olark nor Brevo (Sendinblue) has a ticket queue, and neither Olark nor Brevo (Sendinblue) ships a desktop app. Olark is minutes; Brevo (Sendinblue) is an afternoon.

What each price leaves out

Olark: AI Website Agent $400 a month flat, extra human seats $29 each. Brevo (Sendinblue): Aura AI drafts and summaries inside the plans; no per-conversation AI price. Beside Olark's $400/mo flat and Brevo (Sendinblue)'s Aura AI, Sellio includes an AI credit with each paid plan. Usage consumes that credit; additional credits cost extra, and you can set a spending cap.

How these figures were read

Brevo (Sendinblue) does not print the figures above in a form a fetch can read (Conversations is priced per seat; the marketing plans by email volume. The page could only be read in a local currency, so the seat price is from Brevo's published summaries.), so they are marked unverified here beside Olark's, and Brevo (Sendinblue)'s pricing page should be checked before you decide.
