Bob

macOS 菜单栏里的划词翻译与截图 OCR 工具,选中文字或框选屏幕即可用,不必切换窗口

69/100MonitorFree planFreemium

如果你的主力机是 macOS,又经常读外文、抠图取字,Bob 值得装:划词/截图/输入三种入口覆盖了大部分日常场景,30+ 翻译服务可同时开 10 个对照结果,1.20.0 的独立 OCR 和原图翻译补上了纯提取文字和整图翻译这两块。代价是配置门槛——软件免费,但火山、腾讯、百度、DeepL 这些服务要你自己去申请 API 密钥。想要装完就用、不碰密钥的人,第一次配置会劝退;需要团队共享术语库的话,去看 DeepL Pro 或 Trados;只用 Apple 原生翻译就够的场景,系统自带的划词翻译可能已经够用。

Skip it if

Skip Bob 如果你不用 macOS、或者希望下载后零配置就能翻译,因为它的翻译与 OCR 服务大多要你自己申请并填入 API 密钥。

The 30-second take
Biggest gripe

软件本身从 Mac App Store 免费下载,但火山、腾讯、百度、DeepL 等翻译/OCR 服务的费用要你自己向各家服务商结算,用量大时这笔钱不在 Bob 的账单上。

Price reality

Bob 本体免费,成本几乎全部来自你在火山、腾讯、百度、DeepL、OpenAI 等翻译/OCR 服务商侧的 API 消耗,因此对个人和轻度用户来说总支出可以压得很低。团队若要共享术语库和审校流程,DeepL Pro 或专业 CAT 工具是更对位的支出方向,但那是另一个价位和另一类产品。

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 是一款运行在 macOS 菜单栏上的翻译和 OCR 工具,核心卖点是在任何应用程序里即用即走:选中文字按 ⌥D 划词翻译、按 ⌥S 框选屏幕做截图翻译、按 ⌥A 输入文本翻译,译文窗口悬浮在当前应用上方,点空白处就消失。OCR 侧提供截图 OCR(默认 ⇧⌥S)、静默截图 OCR(识别结果直接进剪贴板,连窗口都不弹)、访达选图 OCR 三个入口,并支持离线识别(macOS 11 以上)、连续识别、二维码识别、自动复制和智能分段。 它是聚合型工具:内置 30 多个翻译服务——Apple、火山、腾讯翻译君、阿里、百度、有道、彩云小译、小牛、Google、Microsoft、Amazon、DeepL、OpenAI——能同时开启最多 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/译文语音朗读(离线语音合成、火山、腾讯、Google、Microsoft)。1.20.0 版本新增独立 OCR 模式和原图翻译,前者让 OCR 脱离翻译流程单独使用,后者通过 OCR 插件把图片内容直接送进翻译链路。 它面向经常读外文资料、处理多语言文档或从图片里抠文字的个人用户。软件从 Mac App Store 免费下载,但多数翻译与 OCR 服务需要你自己申请并填入 API 密钥;官方还提供了插件系统,用来接入没被内置覆盖的服务,以及 PopClip、AppleScript、Raycast 调用和 BobHelper 集成。它不是团队协作工具,没有共享术语库或审校流程,也没有 Windows/Linux 版本。

Behind the Verdict

Bob 的价值不在于某个模型或算法,而在于把「在别人的应用里发起的翻译/OCR 请求」这件事做顺了。默认快捷键清晰(⌥D 划词、⌥S 截图翻译、⇧⌥S 截图 OCR、⌥A 输入翻译),译文悬浮在目标应用上方、点空白即走,这个交互比切窗口去网页翻译少了好几步;静默截图 OCR 更进一步,识别结果直接进剪贴板,不弹任何窗口。 聚合是第二个差异点。翻译侧支持 30+ 服务并允许最多同时开启 10 个结果对照,OCR 侧可在离线识别、火山、腾讯、百度、有道、Google 之间切换——对要交叉验证译文质量的多语言工作者来说,这比绑定单一引擎的工具实用。翻译窗口还带历史记录与收藏夹,并内置简明英汉词典,顺手当成查词工具用。 明显的短板有三个。一是平台,只有 macOS,没有 Windows 和 Linux 版本,官方文档也明确安装途径是 Mac App Store。二是配置,软件本身免费下载,但绝大多数服务要你自己申请并填入 API 密钥,免费额度或费用由各服务商决定。三是协作,它定位个人效率工具,没有团队共享术语库、审校流程这类能力,官方也没有跨平台同步的说法。 插件系统是留给进阶用户的口子:内置没覆盖的翻译或 OCR 服务可以自己接,配合 PopClip 插件、AppleScript、Raycast 和 BobHelper,可以把翻译/OCR 嵌进已有的自动化流程。1.20.0 上线的独立 OCR 模式和原图翻译,说明它仍在往「纯文字提取」和「整图翻译」这两个高频场景上加码。总的判断:为 mac 上的个人高频轻量翻译/取字场景买单是划算的,把它当团队翻译基础设施则不合适。

Real-world workflow fit

Concrete scenarios for the personas Bob actually fits — and what changes day-one when you adopt it.

读外文文献的研究生

在 PDF 阅读器里选中一段英文,按 ⌥D 调起划词翻译,译文悬浮在文档上方,读完点空白处关闭;遇到生词顺手在翻译窗口里查简明英汉词典。

Outcome: 不用切窗口去网页翻译,阅读节奏不被打断;历史记录保留查过的段落,方便回头整理笔记。

需要从教材截图中取字的备考用户

按 ⇧⌥S 框选教材截图做截图 OCR,开启连续识别让多段结果依次拼接,再用智能分段还原段落。

Outcome: 整页讲义的文字被提取到剪贴板,直接粘进笔记软件里整理,不用手打。

要交叉核对译文的多语言工作者

同时开启 DeepL、Google、Microsoft 等最多 10 个翻译服务,对同一段文字比对不同译法,把满意的结果收藏进收藏夹。

Outcome: 一次调用拿到多家译文,减少逐一开网页比对的往返,收藏夹沉淀下常用译法。

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 OCR 插件把整张图片送进翻译链路做原图翻译
  • 通过插件或 AppleScript/Raycast 把翻译接进自己的自动化流程

Limitations

仅支持 macOS,没有 Windows 或 Linux 版本,安装走 Mac App Store。软件免费,但绝大多数翻译与 OCR 服务需要你自己申请并填入 API 密钥,额度与费用由各服务商决定,不是装完就能用的零配置体验。离线文本识别要求 macOS 11 以上系统,且官方说明中提到相关高级识别能力可能受本地硬件影响。没有团队协作、共享术语库、审校流程这类能力,也没有跨平台同步的说明。语音朗读需要选择语音合成服务,部分合成服务同样要接入第三方密钥。

Hidden costs & gotchas

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

  • 软件本身从 Mac App Store 免费下载,但火山、腾讯、百度、DeepL 等翻译/OCR 服务的费用要你自己向各家服务商结算,用量大时这笔钱不在 Bob 的账单上。
  • 每个翻译或 OCR 服务都需要单独申请并填入 API 密钥,配置时间本身就是隐形成本,多个服务开通时尤其明显。
  • 想对照多家译文就要同时开启多个翻译服务,每个被开启的服务都会消耗它自己的额度,等于把单次翻译的成本乘以服务数量。
  • 语音朗读依赖第三方语音合成服务,若选择火山、腾讯、Google、Microsoft 的合成,同样要接入各自的密钥并承担相应额度消耗。
  • 离线文本识别要求 macOS 11 以上系统,旧机器无法使用这条免费路径,只能走需要密钥的在线识别引擎。

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 本体免费,成本几乎全部来自你在火山、腾讯、百度、DeepL、OpenAI 等翻译/OCR 服务商侧的 API 消耗,因此对个人和轻度用户来说总支出可以压得很低。团队若要共享术语库和审校流程,DeepL Pro 或专业 CAT 工具是更对位的支出方向,但那是另一个价位和另一类产品。

Migrating out
  • ↗To DeepL Pro:团队需要共享术语库和统一译法时改用 DeepL Pro,个人划词流程会变重但协作能力补齐
  • ↗To 系统自带翻译:只想零配置、不接任何第三方密钥时退回 macOS 内置翻译能力

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 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 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 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 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 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.

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.
