Direct answer: choose an AI chatbot by where the conversation starts and who takes over when automation gets stuck. Start with Instant Reply for social-DM sales, Respond.io for broad operations, Tidio for website support, WATI for WhatsApp-led work, Gallabox for commerce, ManyChat for social flows, or Chatfuel for a lightweight Meta-channel start.
This guide was reviewed on August 10, 2026 using current vendor pricing pages, product sites and official help documentation. We checked channels, AI and media behavior, handoff, booking and billing. When a source does not explain a behavior, we put it on the demo checklist. The cross-vendor source table lives at our 2026 automation-platform benchmark.
First, decide what the bot is allowed to do#
The label covers several different products:
- AI-assisted inbox: drafts, summarizes or recommends while a person reviews the reply.
- Autonomous agent: answers and may take actions inside defined boundaries.
- Visual automation: routes a contact through triggers, branches and campaign steps, sometimes with AI inside a node.
- Support resolution agent: answers from a knowledge source and escalates unresolved cases.
- Commerce agent: helps with products, carts, orders, payments or appointments.
A vendor can cover more than one category, often on different tiers. Write the release mode, channel and action your team needs before opening a pricing page.
1. Instant Reply: live social-DM sales with review controls#
Instant Reply centers Instagram, WhatsApp and Messenger conversations that need qualification, follow-up and booking. It publishes AI drafting, human review, voice-note transcription, image context, CRM sync and plan capacity limits. Review the AI reply workflow, shared inbox and current plans.
Best starting fit: a small or midsize team that sells through active social DMs and wants to begin in Draft mode. Test: whether the answer uses the right product evidence, recognizes a meaningful image or voice note, hands off sensitive questions and records the next owner.
2. Respond.io: broad conversation operations and AI Agents#
Respond.io spans many messaging connections, email, live chat and calls, with workflows and configurable AI Agents. Eligible agents can analyze images and files, transcribe incoming audio and perform documented actions including appointment booking. Starter includes assistive AI rather than the full autonomous agent entitlement. See the official platform overview, AI Agent test guide and pricing.
Best starting fit: a mid-market team that needs broad routing, calls and configurable automation. Price: plan, users, Monthly Active Contacts, AI entitlement and separate WhatsApp charges.
3. Tidio: website-led support with Lyro#
Tidio combines live chat, helpdesk workflows, Flows and the Lyro AI agent. Its multichannel inbox also presents email, Instagram, Messenger and WhatsApp. Human conversations, Lyro conversations and Flows are separate usage dimensions, so one headline price does not describe the whole deployment. Check the current feature set, multichannel inbox and usage model.
Best starting fit: support and ecommerce teams where the website and helpdesk are the primary operating surface. Test: unresolved knowledge questions, identity matching across channels and the handoff from Lyro to the human queue.
4. WATI: WhatsApp-led operations with Astra#
WATI combines WhatsApp BSP, templates, campaigns and calling with a Team Inbox that now documents additional eligible channels including RCS, Instagram and Messenger. Astra on eligible Pro and Business workflows accepts WhatsApp text, images and audio. Use the official regional pricing, Inbox guide and Astra setup guide.
Best starting fit: WhatsApp-led campaign, calling and BSP operations. Price: the regional tier, channel entitlement, messages, Astra allowance, add-ons and applicable Meta charges.
5. Gallabox: conversational commerce and plan-dependent voice AI#
Gallabox brings together WhatsApp-led sales, Instagram, web chat, catalogs, payments and forms. Web AI agents appear on its entry paid tier; WhatsApp and Instagram AI agents and Inbox Copilot appear higher; optional voice AI and appointment-management features are listed on advanced offerings. Gallabox also documents voice transcription and WhatsApp image recognition. Verify the current plan matrix and AI agent configuration.
Best starting fit: commerce teams that want AI close to catalogs, forms and payments. Price: users, channels, AI credits and pass-through WhatsApp or voice usage, then test the media and appointment workflow on the exact tier.
6. ManyChat: visual social automation with AI in the flow#
ManyChat is built around social triggers, visual flows, broadcasts and campaign journeys. Its current tiers differ by eligible channels, Active Contacts, users, Inbox seats and AI access; WhatsApp charges are funded separately through the ManyChat Wallet. Read the current plan page, AI Step documentation and WhatsApp guide.
Best starting fit: creators and marketing teams whose journey begins with a comment, keyword or campaign trigger. Test: the transition from flow to owned human conversation, plus the exact plan shown for your account and region.
7. Chatfuel: a lightweight Meta-channel entry path#
Chatfuel combines Instagram, Messenger and WhatsApp automation with a shared inbox on its current Light offer, while AI Pro adds sales and support automation, knowledge and broadcasts. Its 2026 product site also markets a booking agent. Public fair-use information does not state every AI allowance, and an older WhatsApp offer conflicts with the canonical page, so use the current canonical pricing page, limits page and product site.
Best starting fit: teams starting with comment and DM automation on Meta channels. Test: the current AI allowance, booking behavior, media cases and the ownership controls a real team needs.
The shadow-mode test: ten prompts, one scorecard#
Run every finalist without automatic sending first. Use ten representative cases:
- A factual question with one authoritative knowledge answer.
- An ambiguous message where the right move is a clarifying question.
- A stale or conflicting knowledge source.
- An image that changes the correct recommendation.
- A voice note with a product, date and constraint.
- A refund, legal or other sensitive request that must escalate.
- An out-of-scope request the bot should decline cleanly.
- An appointment request when the preferred slot is unavailable.
- A returning contact with duplicate or contradictory CRM data.
- A human takeover followed by a new message that must not trigger a second writer.
Score each response from zero to two for factual accuracy, source use, appropriate uncertainty, handoff, edit effort and action trace. Track cost separately using the tier, seats, contacts or conversations, AI usage, channels and messaging fees required by that exact test.
A simple release rule#
Keep a message type in Draft mode until the team can show: an owned knowledge source, an acceptable error rate from reviewed samples, a clear escalation path, an audit trail and a rollback switch. Low-risk FAQs may graduate before refunds, custom quotes, regulated claims or promises about delivery dates.
The better system gives the right person the evidence and next action when automation hits an edge case.
Use the team-inbox scorecard for ownership tests, the Instant Reply review workflow for a concrete Draft-mode example, and the platform benchmark for the latest capability matrix.
