Most AI agents for Slack do one thing well - search your messages, automate a workflow, or answer internal questions. But many teams don't work only in Slack. They have clients on WhatsApp, partners on Telegram, vendors reachable only by phone, and critical threads scattered across LINE and email.
The real question isn't "which AI works best inside Slack?" It's "which AI agent works where you actually work?"
Here are seven options and who each one is built for. Cole is our own product, so read our pick with that in mind, and check each vendor's site for its current features and prices.
Cole is an AI Chief of Staff made by Pocodot, the company that publishes this page. You add it to Slack, WhatsApp, Telegram, LINE and iMessage, including group chats, and it also does email and phone calls. You message Cole like a person, and it handles reminders, email, calendar, research and phone calls, and can use the apps you connect.
Cole has cross-channel memory for your private chats. Link Slack, WhatsApp and your other apps to one Pocodot account and your private chats with Cole share context: notes Cole keeps in one private chat are there in the others, and each one is given a short list of what you and Cole said in the others in the last 24 hours. Groups and Slack channels are kept apart: each uses only its own messages and notes, never your private chats. On paid plans, Cole can also phone numbers you ask for in the United States, the United Kingdom and Thailand. It confirms the number and purpose with you before dialling.
The Free plan gives 150 one-time credits to try Cole in chat. Starter is $19/month for 2,000 credits a month, Pro is $49/month for 8,000, and Max is $199/month for 36,000. Browser tasks and phone calls are on every paid plan. Plans are priced by credits, not per seat. Cole replies in the language you write in.
- 7 channels: Slack, WhatsApp, Telegram, LINE, iMessage, email, and phone
