Bob 是 macOS 菜单栏里的划词翻译和截图 OCR 工具,30+ 翻译服务随选随用

69/100MonitorFree planFreemium

macOS 用户里,读外文多、抠图取字多的人,Bob 装了就很难卸——⌥D 划词、⌥S 截图、⇧⌥S 截图 OCR 三种入口加最多 10 个翻译服务对照,把零碎场景都接住了。1.21.0 的插件 Markdown 输出对写笔记、整理论文的人尤其顺手。真正会劝退的是配置:火山、腾讯、DeepL 这些服务要自己去申请 API 密钥,想装完即用的人第一天就会卡住。要团队术语库和审校流程,去看 DeepL Pro 或 Trados;要 Windows 或网页版,Bob 给不了。

Skip it if

Skip Bob if you're not on macOS, or if you want translation to work the moment you install it — most engines here need you to apply for your own API key with each provider first.

The 30-second take
Biggest gripe

软件免费,但翻译与 OCR 走的是你自己申请的第三方服务额度,火山、腾讯、百度、DeepL 等各按自己的价目表收费,账单由各家分别计收

Price reality

Bob 本身从 Mac App Store 免费下载,真正的支出在第三方翻译与 OCR 服务侧,按各家价目表分别计费,个人和小团队的日常查译用量通常落在这类服务的最低档甚至免费额度内。要对标的话,DeepL Pro 是订阅制的团队向方案,Trados 这类 CAT 工具按席位和协作功能报价,两者都提供 Bob 没有的共享术语库与审校流程;只想省钱、用量又小的人,系统自带翻译和 Google 翻译网页版是零成本退路。

What people actually say about Bob — is it worth it?

We ran a structured research pass across product reviews, community discussions, and post-purchase forum threads to surface the patterns vendors won't publish themselves. Below: the recurring strengths, the hidden costs people mention most, and the cohort that consistently regrets adopting this tool.

29 mentions across 8 sources (Reddit, Hacker News, YouTube, Product Hunt, App Store, Stack Overflow, GitHub, Lemmy), 93 more we could not attribute · researched Sep 21, 2026.

45% positive55% critical

Weighted by the 122 posts each of 8 sources contributed.

Recurring strengths
  • +9,748 GitHub stars and an active repo signal genuine, sustained user adoption
  • +Maintainer closes localization and feature issues quickly, often within days
  • +Open plugin system: users extend Bob with third-party services like bob-plugin-minimax
  • +Screenshot, selection, and input translation stay inside any app without window switching
  • +Deep OCR integration (screenshot, silent, Finder, offline) differentiates it from PopClip-style tools
Recurring frustrations
  • −Almost all public community discussion is noise; real English-language feedback is scarce
  • −Most translation and OCR services require self-provisioned API keys, not turnkey usage
  • −MiniMax support was only recently addressed via an unofficial plugin, not built in
  • −Auto-detect language long defaulted to English/Chinese only, annoying multilingual chat users
  • −Mac-only; Windows users have been asking for years with no official plan

About Bob

FreemiumBeginner-friendlyAPI availableDesktop · Plugin

Bob 是一款 macOS 菜单栏软件,把翻译和 OCR 塞进一个图标里,平时不占地方,需要时一个快捷键走完全程。翻译有三个入口:选中文本按默认 ⌥D 划词翻译,按默认 ⌥S 框选屏幕做截图翻译,按默认 ⌥A 在窗口里敲文本翻译;译文浮在当前应用上方,点下空白处就消失,不用在程序之间来回切。OCR 这一侧提供截图 OCR(默认 ⇧⌥S)、静默截图 OCR(结果直接进剪贴板、不弹窗口)、访达选图 OCR 三个入口,并支持离线识别、连续识别、二维码识别、智能分段和自动复制。它属于聚合型翻译工具,内置 30 多个翻译服务,Apple 翻译、火山翻译、腾讯翻译君、阿里翻译、百度翻译、有道翻译、彩云小译、小牛翻译、Google 翻译、Microsoft 翻译、Amazon 翻译、DeepL 翻译、OpenAI 翻译都在列表里,最多可以同时开启 10 个服务横向对照结果,OCR 引擎同样可换(离线文本识别、火山 OCR、腾讯 OCR、百度 OCR、有道 OCR、Google OCR)。翻译窗口带历史记录和收藏夹,也能当简明英汉词典查词,并支持原文与译文语音朗读,语音合成可选离线、火山、腾讯、Google、Microsoft。1.21.0 起插件翻译结果支持 Markdown 输出,抓论文和文档时格式不容易散。目标用户是经常读外文资料、处理多语言文档或从图片里抠文字的个人:研究者、译者、法务和工程岗都能用上。官方还提供插件系统接入没被内置覆盖的服务,以及 PopClip、Raycast、AppleScript 调用和 BobHelper 集成。和系统自带翻译相比,Bob 的优势在多引擎对照和 OCR 的完整度;和 DeepL Pro、Trados 这类团队向工具相比,它不提供共享术语库、审校流程和协作管理。它只有 Mac 版本。

Behind the Verdict

Bob 的产品逻辑很清楚:它不做翻译本身,它做翻译的调度层。翻译引擎由 Apple、火山、腾讯、阿里、百度、有道、彩云小译、小牛翻译、Google、Microsoft、Amazon、DeepL、OpenAI 这些服务商提供,Bob 负责把它们收进一个菜单栏图标,配上快捷键、悬浮结果窗、历史记录和收藏夹。这意味着两件事:一是你能把同一段外文丢给最多 10 个引擎对照,译法分歧一目了然,这是系统自带翻译给不了的;二是你的使用体验会跟着第三方服务商的政策走,官方公告里就记录过小牛翻译关闭免费 API、百度翻译和 OCR 额度调整这类变动。 OCR 这一侧比翻译更能体现工程投入。截图 OCR、静默截图 OCR、访达选图 OCR 是三个不同入口,静默模式干脆不弹窗,识别结果直接进剪贴板,批量抠图取字时比截图-识别-复制三步流程省事得多。再叠加离线识别(需 macOS 11 及以上)、连续识别拼接、二维码识别、智能分段和自动复制,这套组合在 Mac 上的同类工具里属于完整度靠前的位置。翻译窗口兼作简明英汉词典,原文译文都能语音朗读,语音合成也可换。 短板同样明确。第一,只有 macOS 版本,没有 Windows、Linux 或网页版,跨平台团队没法统一。第二,它是个人的效率工具而非团队平台,没有共享术语库、审校流程和成员协作管理,翻译团队要做一致性管控得另找工具。第三,也是最现实的摩擦点:软件从 Mac App Store 免费下载,但绝大多数翻译和 OCR 服务需要你自己去服务商处申请密钥并填入,额度和费用由各服务商单独计收,不是装完就能用的零配置体验。愿意花半小时把火山、DeepL、腾讯几家的密钥配好的人会觉得很值;指望开箱即用的人会在第一步就卡住。 1.21.0 给插件翻译结果加了 Markdown 输出,这个改动对写笔记、整理论文和文档的人比听起来有用——表格、标题、列表不会在复制粘贴里散架。配合插件系统、AppleScript、Raycast 和 PopClip 调用,Bob 也能被塞进已有的自动化流程里,而不是只能手动按快捷键。

读外文论文的研究生

在 PDF 阅读器里选中一段英文,按 ⌥D 拿到译文,遇到术语再切到内置简明英汉词典查词,把满意的译法收藏进收藏夹

Outcome: 不用切到浏览器粘贴,阅读节奏不被打断,整个学期的查译记录留在历史里

处理多语言合同的法务或翻译岗

对同一段条款开启 DeepL、Google、腾讯三个引擎对照译法,关键句用 ⌥S 截图翻译处理扫描件里的段落

Outcome: 译法分歧摆在同一个窗口里,比单引擎结果更容易发现歧义

需要从图片批量取字的工程或运营岗

在访达里选中一批截图,用访达选图 OCR 配合连续识别把文字依次拼进同一文本框,再靠自动复制直接进剪贴板

Outcome: 整批图片的文字一次性拿到,不用逐张打开截图工具再手工复制

Use Cases

  • 在任何应用中选中文本,按 ⌥D 一键得到译文
  • 按 ⌥S 框选屏幕区域,直接翻译图表或视频字幕
  • 用静默截图 OCR 把图片文字批量拷进剪贴板而不弹窗
  • 在访达里选中一批图片文件做 OCR 提取文字
  • 开多个翻译服务对照同一段外文的译法差异
  • 读外文文献时用内置简明英汉词典快速查词
  • 用插件把整张图片送进翻译链路,并让结果以 Markdown 格式输出
  • 通过 AppleScript 或 Raycast 把翻译接进自己的自动化流程

Limitations

仅支持 macOS,需从 Mac App Store 安装,没有 Windows 或 Linux 版本。软件本身可从 Mac App Store 免费下载,但大多数翻译与 OCR 服务需要用户自行申请并填入 API 密钥,额度与费用由各服务商分别决定,并非开箱即用的零配置体验。离线文本识别要求 macOS 11 及以上系统。官方公告中记录了多次第三方服务变动(如小牛翻译关闭免费 API、百度翻译/OCR 额度调整),说明使用体验会受外部服务商政策影响。翻译多开最多同时开启 10 个服务。不提供共享术语库、审校流程与成员协作管理。

Hidden costs & gotchas

What the public pricing page doesn't put in bold. Captured from pricing-page footnotes, contract terms, and recurring complaints.

  • 软件免费,但翻译与 OCR 走的是你自己申请的第三方服务额度,火山、腾讯、百度、DeepL 等各按自己的价目表收费,账单由各家分别计收
  • 配置多个引擎时要在各家服务商分别申请密钥并管理额度,开通和续费的行政成本落在你身上
  • 免费额度和费率会跟着服务商政策变,官方公告里就出现过小牛翻译关闭免费 API、百度翻译/OCR 额度调整这类情况,原先够用的免费额度可能突然不够
  • 离线识别需要 macOS 11 及以上系统,系统版本偏旧的机器只能走在线引擎,从而产生服务商侧调用费用

Where the pricing makes sense

The company stage and team size where Bob's pricing actually pencils out — and where peers do it cheaper.

Bob 本身从 Mac App Store 免费下载,真正的支出在第三方翻译与 OCR 服务侧,按各家价目表分别计费,个人和小团队的日常查译用量通常落在这类服务的最低档甚至免费额度内。要对标的话,DeepL Pro 是订阅制的团队向方案,Trados 这类 CAT 工具按席位和协作功能报价,两者都提供 Bob 没有的共享术语库与审校流程;只想省钱、用量又小的人,系统自带翻译和 Google 翻译网页版是零成本退路。

Tools that pair well with Bob

Common stack mates teams adopt alongside Bob, with the specific reason each pairing earns its keep.

Featured Head-to-Head Comparisons

Bob vs Genspark

You are not choosing between these two. Genspark is a broad AI workspace for synthesizing research and producing documents, slides and automations; Bob is a macOS-only translation and OCR utility that lives in the menubar and is called up on demand. If you need cited multi-source summaries or no-code internal tools, buy Genspark. If you need to translate a PDF paragraph or OCR a screenshot on a Mac without leaving the app, buy Bob. Owning both is normal: Bob handles the in-place reading comprehension, Genspark handles the synthesis and output around it.

Bob vs Poke Interaction Co

Poke and Bob serve completely different needs: Poke is a broad AI assistant for messaging-based task management and automation, while Bob is a focused macOS utility for translation and OCR. Choose Poke if you want an all-in-one assistant handling email, calendar, and health from your chat apps; choose Bob if you're a macOS user who needs lightweight, always-available translation and text extraction. They are not direct competitors.

Bob vs Gem

Gem and Bob serve completely different needs: Gem is an enterprise-grade AI recruiting platform for talent teams consolidating multiple hiring tools, while Bob is a lightweight macOS utility for quick translation and OCR. Choose Gem if you’re scaling hiring with AI agents; pick Bob for personal text extraction on a Mac. They are not direct competitors — your choice depends on whether you need to hire at scale or translate text efficiently.

Bob vs Guesty

If you run a vacation rental business, Guesty is the clear choice with AI-automated messaging and bank reconciliation, while Bob is irrelevant unless you also need a macOS translation/OCR tool. These tools serve completely different needs; choose based on whether you manage properties or need text extraction.

Bob vs Gemini

These two don't compete, and treating them as a head-to-head would mislead you. If your problem is "assistant that drafts, researches, and reads my Gmail/Docs/Calendar," Gemini is the answer, and Bob is irrelevant. If your problem is "translate or OCR whatever is on my Mac screen in any app without leaving the window," Bob solves it directly and Gemini is the wrong shape of tool — it's not built for in-app text capture. A Google Workspace power user could reasonably install both, but that's stacking complementary tools, not picking a winner.

Bob vs Superhuman

These two aren't substitutes, so there's no single pick — buy both, or neither, and you'd be fine either way. If your problem is an overflowing inbox, sales pipeline, or Slack-and-Salesforce workflow that needs AI agents, Superhuman is the answer and Bob is irrelevant to you. If your problem is reading a Japanese PDF, translating a contract, or pulling text out of a screenshot on your Mac, Bob solves it for free (plus whatever you pay your translation API providers) and Superhuman never touches that job. Only overlapping buyer: a solo Mac user who wants both faster email and instant translation — in which case you'd run them side by side, not choose.

Bob vs Saner Ai

These two tools don't compete — they solve different problems for different people, so a head-to-head choice rarely makes sense. Saner is for the ADHD professional drowning in Gmail, Slack, and Drive who wants one AI inbox and chat assistant (Skai) to organize and recall everything, and it's a service you connect your accounts to. Bob is for the macOS reader who needs to translate a selected word or pull text out of a screenshot without switching windows, and it's a utility mostly powered by API keys you supply yourself. If your pain is scattered information and follow-through, buy Saner. If your pain is reading foreign documents and extracting text from images on a Mac, install Bob. Buying both is entirely plausible; choosing between them is not.

Bob vs Mindful Memo

These two are not competitors and no buyer should be choosing between them. MindfulMemo.com is a $7,295 premium domain listing (or $303.96/mo over 24 months) — you buy it only if you specifically want that exact .com for a mindfulness, journaling, or note-taking brand. Bob is a free macOS translation and OCR utility whose real cost is your time setting up API keys, and whose 1.20.0 release makes OCR usable on its own. If you need translation/OCR, buy neither of these considerations apply — download Bob. If you need a brandable domain, Bob is irrelevant.
