Best Discord AI Chatbots for Servers (Compared)

What to decide first

An AI chatbot in a Discord server does one of three jobs: answers support questions, chats with members for fun, or acts as a character. The bot you want changes with the job. Before you compare, decide where replies should happen (one channel, mentions anywhere, or inside tickets) and who pays for the model usage.

How we picked

This is based on each bot's own pages and docs as of November 2026. We did not benchmark answer quality, because it depends on the model and on the prompt you write. We compared setup effort, where the bot replies, how cost works, and what control you keep over your data and keys.

1. Noxyr: free AI chat for channels and tickets

Best at: servers that already run tickets and want a first responder. AI chat is a module that is off by default. /aichat setup takes a channel where the bot replies to every message, whether it should answer when mentioned elsewhere, a ticket help option and your own system prompt. Replies also work inside tickets through an AI Help button, and staff still see the whole exchange. See the Discord AI chatbot page and the support guide.

Your own keys: the own AI keys page says you can add OpenRouter, Groq, NVIDIA or Token Harbor keys, group them in order, and run every AI feature on them with no Noxyr limit. Keys are stored encrypted and the dashboard shows only the last 4 characters. When all your keys are limited, Noxyr's own AI answers again so replies never just stop.

Limit: it is a text assistant inside Discord, shaped by your prompt. The docs describe no knowledge-base upload, so put the facts it needs into the system prompt. Everything is free.

2. Quickchat AI: hosted assistant with a knowledge base

Best at: no-code setup with your docs. Quickchat's Discord page says you create a bot from a name and plain-language instructions, optionally add docs or a wiki, then add it from External Apps. Members can mention it or use /ask. It can read recent channel messages and images and reply in the member's language.

Limit: it runs on credits. As of November 2026 its page lists Free at $0 for personal, non-commercial use with 50 credits a month, Starter at $9 a month for commercial use with 150 credits, Basic at $29 with 500 and Essential at $99 with 3,000. Each AI reply uses credits. A custom avatar and DMs need your own Discord app and bot token.

3. MimicAI: bring your own key, characters

Best at: roleplay and character bots. Its page describes a bring-your-own-key platform with no subscription, supporting Google Gemini, OpenRouter and Ollama, where each character can get its own bot account.

Limit: it is marked as beta on its page, and we could not confirm moderation or support features. Treat it as a hobby-grade tool until you have read its docs.

4. TomoriBot: open-source hobby bot

Best at: people who want to read the code. It is described as a free, open-source project where you can invite the public bot or self-host from its repository.

Limit: a hobby project has no service promise. Expect to read the README, and check that it is still maintained before you depend on it.

5. Self-hosting an open-source bot

Best at: full control over prompts, logs and the model. Many GitHub projects take a Discord bot token and a provider key and set personality with an initial prompt.

Limit: you run the server, rotate keys, handle Discord API changes and watch for abuse. For a support bot that customers rely on, that upkeep is real. Read custom bot vs self-hosting first.

Comparison table

Safety checklist for any AI bot

• Tell the bot in its prompt to say when it does not know and to point to a ticket.
• Never let it promise refunds, prices or staff decisions.
• Keep it out of private staff channels.
• Do not share one provider key between people. Providers can suspend accounts for that.

Pick by need

• Free support helper next to tickets: Noxyr.
• Answers from your own documentation: Quickchat AI.
• Characters and roleplay: MimicAI.
• Full control: self-host.
