01 / Best for answering DMs on eleven platforms with one AI agentBold Agent Kit
Bold Agent Kit is one AI agent that answers private messages on eleven platforms: Messenger, Instagram, WhatsApp, Telegram, LINE, Viber, Slack, Discord, Bluesky, Reddit and X. Each is connected with your own app credentials, your Meta app, your WhatsApp Business account, your Telegram bot and so on, so the account and the rate limits stay yours, and auto-reply is a separate switch per platform. Replies go out inside each platform's reply window, once per thread, within a daily cap per sender and hourly caps per channel, and every conversation lands in one inbox, where you can take a thread over and hand it back.
It answers from a knowledge base rather than flows: your documents, Q&A pairs, prices, hours and the pages of your site it may link to, so it handles the question as it was asked and says only what that material supports. Then it asks for the next step, offering real open slots from Google Calendar, Microsoft 365, Calendly, Cal.com, Acuity, Zoho Bookings, Square Appointments or HubSpot Meetings and booking the one the customer picks, or taking the email address. The same agent answers the website chat, email, texts and calls, reads a connected Shopify, WooCommerce, Wix or Squarespace store before it replies, and merges the handle, email address and phone number belonging to one person into one contact.
It is narrower than Chatfuel in ways worth saying plainly: it does not reply to comments, post content, run comment-to-DM or keyword funnels, or broadcast to DM subscribers, and it has no flow builder. Choose it if the DMs themselves are the work, on more platforms than three, and you want the conversation to carry on by email, text or phone with a booking at the end. It is $25 a month or $200 a year for the whole account, every platform and unlimited agents included, with the model on your own key from any of sixteen providers, billed to you at cost.
