𝙆 Baidu Translater

The third of KayTool's translation nodes, and the odd one out: where AIO Translater and Tencent Translater run on a backend the pack's author manages for you, Baidu Translater wants your own credentials. You register at Baidu's Translate Open Platform (fanyi-api.baidu.com) for an App ID and App Key, plug them into the node, and it calls Baidu's translation API directly on your account. The trade-off is straightforward: more setup, but a translation path that's yours - no dependency on someone else's hosted proxy staying up.

The language list here is also noticeably narrower than the other two translators in this pack: just Simplified Chinese, Traditional Chinese, and English (plus Auto-detect as a source option). If you need translation between other language pairs, AIO Translater or Tencent Translater cover far more ground; this node is specifically the Chinese/English one.

How it works

Same dual-slot pattern as Tencent Translater - Text_A and Text_B in, translated A and B out - plus a Translate toggle to switch the whole thing off (useful for testing your graph's wiring without spending API calls). The node's own tooltips are explicit about the two credential fields: ID is your Baidu App ID, Key is your Baidu App Key, both obtained by registering at the platform above. Per the pack's docs, once you've entered them the node saves that configuration for future use, so you're not expected to re-type your key every session.

The inputs and outputs that matter

• Text_A / Text_B (STRING, multiline) - text to translate.
• From (choice of 4: Auto / Simplified Chinese / Traditional Chinese / English).
• To (choice of 3: English / Simplified Chinese / Traditional Chinese).
• ID / Key (STRING) - your Baidu App ID and App Key, per the node's own tooltips.
• Translate (BOOLEAN, default true) - on/off switch.
• A / B (STRING, outputs, each with a tooltip confirming they correspond to Text_A/Text_B).

Installing it

Bundled with the full KayTool pack: ComfyUI Manager → search KayTool → install → restart, or cd ComfyUI/custom_nodes && git clone https://github.com/kk8bit/KayTool and restart. On top of that, this specific node needs a free Baidu Translate Open Platform account - register at fanyi-api.baidu.com to get the App ID and App Key the node asks for.

Common issues

An empty or failed translation with this node points almost entirely at the credentials: a missing, expired, or mistyped ID/Key pair is the classic failure mode for any bring-your-own-API-key node, and unlike the other two translators in this pack there's no shared fallback to lean on if yours isn't working - you'll need to double-check the values against what Baidu's platform actually issued you. If you're only translating between Chinese and English, this node is genuinely the most self-contained option in the pack (your account, your limits, no dependency on the author's backend); for anything else, the language list is simply too narrow and you're better off with AIO Translater or Tencent Translater instead.
