VivaDialog vs Chatfuel
Chatfuel builds chatbot flows for WhatsApp, Instagram, and Facebook. VivaDialog is a shared inbox with keyword and AI rules for Facebook, Instagram, and Threads. Both charge a low flat price; they differ in channels and in what happens when AI use runs high. Chatfuel's details as we found them on 20 Oct 2026.
| Topic | VivaDialog | Chatfuel |
|---|---|---|
| How you pay | A flat price per workspace each month. Each plan has monthly quotas for conversations and AI replies. | A flat price per business, with unlimited active contacts and messages. AI use has a fair-use limit per billing period. |
| Lowest paid plan | Silver: $7 a month billed monthly, or $5.60 a month billed yearly. 500 conversations and 200 AI replies a month. | Business: US$20 a month billed monthly, or US$18 a month billed yearly (US$216 a year). Includes US$20 of AI credits a month. |
| When AI use runs out | AI replies pause until next month. Fixed-text rules, the inbox, and manual replies keep working. You can switch to your own AI key at any time in Settings. | The bot pauses and the AI assistant stops replying until the limit resets, or until you renew early. Keyword replies, button flows, and broadcasts do not count toward the limit. Your own OpenAI key can be connected through support. |
| Instagram comments | A rule can reply to the comment in public and send the commenter one private DM, triggered by keywords or by every comment. | Replies to post and Reels comments automatically, and a comment or keyword can start a DM conversation that continues as a flow. |
| Threads | Threads replies in the same inbox, answered by you or by your rules and AI. Threads has no API for DMs. | Not listed among Chatfuel's channels. |
| Other channels | Not yet. Facebook, Instagram, and Threads only. | WhatsApp (official API), TikTok, and a website chat, besides Facebook and Instagram. |
| Automation | Keyword or pattern rules that reply with fixed text or AI, send the commenter a DM, send one reminder, tag, or assign. | Visual flows with templates, lead capture, and integrations such as Google Sheets, Zapier, and Stripe. |
| Free trial | A 14-day trial without a card opens after the closed beta. | A free trial without a card on every plan. |
