Frequently Asked Questions

Missive + AI vs Chatlyn: which should you choose?

For hospitality businesses needing a purpose-built AI omnichannel hub that integrates directly with PMS and automates guest journeys, Chatlyn is the clear winner. General teams focused on email collaboration with flexible AI can choose Missive + AI, especially if they want to bring their own API keys and have a richer task management layer. Neither tool replaces the other — pick by industry and core workflow.

Can Chatlyn be used outside hospitality?

Not recommended — Chatlyn is purpose-built for hospitality with PMS integrations and guest journey automation. General teams would miss features like email threading, task management, and external CRM integrations that tools like Missive offer.

Does Missive + AI support multiple AI models by default?

Yes, Missive supports OpenAI (GPT-5 mini, GPT-5, GPT-4o mini), Anthropic, and Gemini. You can bring your own API key for any of these, avoiding per-user AI fees.

Which tool has better AI for drafting replies?

Both can draft replies, but Missive provides more granular control with custom prompts using [message], [selection], and [documentation] placeholders, plus AI Rules for auto-replies. Chatlyn’s AI is more focused on guest-facing chatbot conversations.

Does Chatlyn offer a free trial?

Chatlyn’s pricing page says 'Contact for pricing', so a free trial may be available upon request. Missive offers a 14-day free trial with no credit card required.

Can I use Missive for WhatsApp?

Missive supports SMS and social inboxes but does not natively integrate WhatsApp Business API like Chatlyn does. For WhatsApp-centric teams, Chatlyn is the better choice.

Which tool is easier to set up?

Missive is simpler for email teams — just connect your email accounts and invite team members. Chatlyn requires PMS integration, AI training on documents, and configuring automation flows, which is heavier but yields more tailored automation for hospitality.

Do both tools have mobile apps?

Yes, both offer mobile apps: Chatlyn’s app is for on-the-go management of guest comms; Missive’s app allows replying to shared inboxes and managing tasks.

Which tool is better for a remote team?

Missive is better suited for remote teams due to its internal threads, collaborative drafting, task assignments, and integrations with Slack, Zoom, and Google Meet. Chatlyn’s focus is more on guest-facing communication than internal collaboration.
