免费+订阅Free + subscription 会议转写Meeting transcription 机器人入会Meeting bot 英文向English-focused 纪要行动项Meeting action items partial lifecycle: active 核验Checked 2026-10-22

Otter 是「机器人入会」的会议转写纪要产品：实时转写+行动项+跨会议问答，英文向成熟；机器人进你的会议这件事本身要过合规。

Otter is the bot-joins-the-meeting transcription & notes product: real-time transcription + action items + cross-meeting Q&A, mature for English; the bot entering your meeting is itself a compliance question.

适合与不适合When to use it, when not to

适合：英文会议/访谈记录、小团队纪要流水线。不适合：中文会议主打、隐私极敏感场景、免费档当长期方案。

Fits: English meetings/interviews, small-team note pipelines. Not a fit: Chinese meetings as the main use, privacy-critical settings, treating the free tier as a long-term plan.

出品属地Origin: 国外出品foreign-made　Otter.ai（美国旧金山，原 Blue Note 公司）。Otter.ai (San Francisco, US; formerly Blue Note).
国内使用Direct access: 大陆可直连direct OK　otter.ai 大陆直连实测 200（2026-10-22）。otter.ai measured 200 direct from mainland (2026-10-22).
备案状态CAC filing: 未见于备案名单not in filing list：未见于网信办公示名单（2026-10-22 检索）；该产品未面向大陆公众提供服务，备案不适用。not in the CAC public registry (searched 2026-10-22); the product does not serve the mainland public, so filing does not apply.

备案信息以网信办《生成式人工智能服务已备案信息》公示名单为准（按批次滚动更新，本站只抄编号不解读）；「大陆可直连」是本站从大陆网络直连实测的结果，不是厂商承诺。GitHub 类站点当日实测有波动，口径写在依据里。Filing status is quoted from the CAC public registry (updated batch by batch; this site copies the number and does not interpret it). "Direct access" is this site's own reachability measurement from a mainland network, not a vendor promise. GitHub-hosted sites fluctuated on the measurement day — the note says so.

固定坐标系Fixed coordinate system

8 个维度dimensions, 与同分区其他对象逐项可比each comparable item by item against others in the same section.

模型与开放条件Model & openness: 自研转写/纪要模型线（Otter 自述转写引擎）；用户不选模型。曾有「用客户音频训练」的隐私争议史（2021-2022 公开报道叙事）——当前训练口径按官方隐私页（未逐条核验）。
A self-developed transcription/minutes model line (Otter's self-described transcription engine); users do not pick models. There was a privacy controversy over "training on customer audio" (2021-2022 public-report narrative) — the current training stance follows the official privacy page (not verified item by item).
运行位置Where it runs: 网页+移动 App+会议平台机器人接入（Zoom/Meet/Teams 机器人入会实时转写，官方产品面）；处理在厂商云端。
Web + mobile App + meeting-platform bot joining (Zoom/Meet/Teams bots join meetings for live transcription, official product surface); processing on the vendor's cloud.
本地文件Local files: 会议录音/转写/纪要存账户侧云端；导出（txt/csv/srt 等）归本地。未见官方声明的本机处理形态。
Meeting recordings/transcripts/minutes stored on the account-side cloud; exports (txt/csv/srt etc.) count as local. No officially stated local-processing form seen.
关机后的任务Tasks after shutdown: 实时入会转写是核心形态（机器人常驻会议）；批处理上传并存；无「关机续跑」概念（云服务）。
Live bot-joined meeting transcription is the core form (a bot resides in the meeting); batch upload alongside; no "keep-running-after-shutdown" concept (cloud service).
工具与扩展Tools & extensions: 实时转写+说话人分离+自动纪要/行动项（官方产品面）、Otter Chat（对转写提问，官方产品面）、协作编辑与分享；企业面有管理控制台（官网所见）。
Live transcription + speaker diarization + auto minutes/action items (official product surface), Otter Chat (ask questions of the transcript, official product surface), collaborative editing and sharing; the enterprise side has an admin console (seen on the official site).
上下文与记忆Context & memory: 跨会议知识库是产品叙事（历史会议可检索/问答）——这是它的「记忆」面，细节未逐条核验。
A cross-meeting knowledge base is the product narrative (past meetings searchable/answerable) — that is its "memory" surface, details not verified item by item.
权限与限制Permissions & limits: 账号+订阅+企业体系（D9：价格不采）；免费档有月度转写分钟上限（官方定价页叙事，具体额度未逐条核验）； 会议录音涉多方隐私——机器人入会的知情同意是使用方责任（条款口径未逐条核验）。
Account + subscription + enterprise system (D9: pricing not collected); the free tier has a monthly transcription-minutes cap (official pricing-page narrative, exact quota not verified item by item); meeting recordings involve multiple parties' privacy — informed consent for a bot joining is the user's responsibility (terms stance not verified item by item).
适合什么任务Best for: 适合：会议记录/访谈整理（英文向成熟）、个人与小团队的转写纪要流水线。不适合：中文会议主打（转写引擎英文向叙事）、隐私极敏感场景（云端+机器人入会）、把免费档当长期方案（分钟数限制）。
Fits: meeting/interview documentation (mature for English), transcription-minutes pipelines for individuals and small teams. Does not fit: Chinese meetings as the mainstay (the transcription engine has an English-leaning narrative), extremely privacy-sensitive scenarios (cloud + bot joining), treating the free tier as a long-term plan (minute limits).

头号误解Top misconception

机器人入会模式=第三方机器人进你的会议——企业使用前要过 IT/合规审查，知情同意是使用方责任Bot-joins mode = a third-party bot entering your meeting — enterprises need IT/compliance review; informed consent is the user's responsibility
「用客户音频训练」争议史（2021-2022 公开报道）——当前口径以官方隐私页为准，敏感场景读条款原文A public 'trained on customer audio' controversy (2021-2022 reporting) — current practice follows the official privacy page; sensitive settings should read the terms text
转写引擎英文向成熟——中文会议准确率要实测，别按英文体验推断The engine is English-mature — Chinese meeting accuracy needs testing; don't infer from the English experience

实测记录Measured runs

本档未跑音频质量与延迟测试；结论只覆盖能力面与许可面。

实测建议（三条，都指向官方可读页没给的东西）：

中文/中英混说会议的转写准确率
Otter Chat 对多场历史会议跨检索的召回质量
机器人入会在企业 Zoom 策略限制下的实际可达性

This site has not completed measured runs. The coding-oriented test protocol is at protocols/coding/_protocol.md (the coding task suite does not apply to creation products).

Suggested measurements (three, all pointing at things the official readable pages do not give):

Transcription accuracy on Chinese / Chinese-English mixed meetings
Otter Chat's recall quality across multiple past meetings
Bot joining's actual reachability under enterprise Zoom policy restrictions
