Add BabelBot to DiscordLast updated Oct 7, 2026.
HephBot Translate suits servers that want unlimited free core translation and channel mirrors. It also has private lookups and a bring-your-own-key option, called BYOK. BabelBot suits servers that want managed translation with a choice of delivery modes. Its paid plans add supported attachment-content translation, while Ultra and Founder Access add voice chat translation.
Both bots can help members follow conversations across language channels. Your choice depends on what members need to understand. A gaming community may need free text translation and mirrors. A support server may need translations of screenshots and audio clips. Check those everyday tasks before choosing a paid plan.

Free translation for everyday chat
A small friend server may only need members to read ordinary messages in another language. HephBot includes unlimited free core translation and mirrors. That gives a server focused on text and mirrored channels a clear reason to try HephBot before paying for extra AI options.
BabelBot Free includes 2 target languages and 5 custom words. New servers get 100 AI translations to start, then 50 AI translations per month. After the AI allowance, translations continue without a monthly limit through BabelBot's in-house translator. The AI allowance is not a cap on all messages.
You need to check which work requires AI. Languages marked AI only, messages containing custom words, and on-demand requests still need AI allowance. For a friend server with normal chat, Free can keep it translating after that allowance runs out. For a community that relies on custom terms, the remaining AI allowance matters more. See billing and limits before you test.
Keep busy channels readable
In a busy announcements channel, members may only want to read the original posts. BabelBot's thread delivery puts translations in a thread attached to the source message. Members who need a translation can open that thread. Members who read the original language have fewer translated messages to scroll past in the main channel.
BabelBot groups multiple target languages in the translation thread. It also supports channel replies and Replace the original. Replacement posts the translated text with the member's name and avatar, then deletes the original after confirming delivery. With multiple target languages, it includes the original text first. Choose the format your members can follow, then check it in Discord.
Linked channels suit communities that already have separate language rooms. BabelBot bridges let members write in their language channel and read translated copies from the others. HephBot has mirrors, webhook-as-user output, and thread features for flag results and mirrored workflows. Both bots support linked language channels, so this feature alone does not settle the choice.
For a gaming community, test a question and its reply across your language rooms. For announcements, check how translations affect the main channel. Read BabelBot's delivery rules and bridge guide if you need help choosing between these layouts.
Read attachment contents and live speech
A support member may post a screenshot of an error instead of typing its text. Forwarding that image helps staff see the problem. Staff who cannot read the language still need a translation of the words inside it. HephBot forwards attachments, embeds, and links through mirrors. Its public documentation does not claim attachment-content translation.
BabelBot translates the contents of supported PDFs, images, video attachments, and audio files on Pro, Ultra, and Founder Access. You must enable media translation and have AI allowance available. BabelBot posts the translated result as a Discord message. It keeps the original file as it is. Check the media translation guide for supported content and setup.
Voice notes are audio clips posted as messages. BabelBot handles those through media translation. Voice chat translation covers people speaking during a live Discord call. Ultra and Founder Access include that feature. Members read translated text in the voice channel's text chat while the session runs. BabelBot does not speak the translation back into the call.
This can help a gaming group read a teammate's spoken instructions or follow a multilingual meeting. HephBot's public documentation does not describe live voice chat translation. Keep that distinction in mind if calls drive your choice. BabelBot members use /voice start, /voice stop, and /voice status to operate sessions. Live sessions have separate limits and do not use normal message AI quota. See voice chat translation.
Where HephBot fits better
An admin who wants control over AI models and prompts has a reason to choose HephBot. Its BYOK option lets you use your own provider account. You can manage provider costs through that account and choose the controls that fit your server. This suits an admin who wants to take responsibility for the AI setup.
HephBot also has managed Groq user and server plans. You can choose a managed option if you want AI translation without supplying your own key. BabelBot's paid plans include managed AI too, but BabelBot does not offer BYOK. Managed AI without a key is available from both bots; provider control is HephBot's advantage.
Private user translation gives HephBot another reason to fit a mixed-language server. A member who needs occasional help reading messages may prefer a private lookup. Webhook-as-user mirror output may also suit a community that wants mirrored messages to appear under the speaker's identity. If those are your main tasks, give them more weight than media features you would rarely use.
Custom words and plan costs in practice
A gaming community may use a place name that ordinary translation changes into an unrelated word. BabelBot lets you save the wording you want as a custom word. You can also keep a name unchanged. Free includes 5 custom words, Pro includes 25, and Ultra and Founder Access include 100. Those rules need AI allowance, including on Free. See custom words for how to set and test them.
BabelBot Pro includes 5,000 AI translations per month and media translation. Ultra includes 25,000 AI translations per month and adds voice chat translation. One server plan covers the members on that server. For a support server, Pro may cover the attachment workflow you need. You need Ultra or Founder Access if live calls also require translated text.
Founder Access uses a one-time payment for one server at a time and includes unlimited AI translations. The public information used for this comparison lists no one-time HephBot plan. Check HephBot's available plans before treating that gap as a permanent limit. Choose Founder Access if its payment schedule and included features fit your server.
For HephBot, choose between free core translation, managed user or server AI plans, and BYOK. With BYOK, consider the provider bill alongside the bot's options. You need HephBot's prices and paid usage limits to make a fair total-cost comparison. Compare the plan that covers your actual tasks before paying.
Try the workflow your members will use
Start with one channel and the languages your members need. Use a full sentence from a normal conversation. Include a community term if you plan to use custom words. Check that members can find and read the result in the delivery format you chose.
Use BabelBot's quick start to test ordinary text on Free. For HephBot, focus your trial on the features you need, such as mirrors or private lookups. If supported attachments or live calls are essential, test those with the relevant BabelBot plan. Check the result inside Discord before relying on the bot for a busy event or support shift.
