Briefy

Briefy is an AI knowledge assistant that turns long web pages, YouTube videos, PDFs, email threads and podcasts into structured summaries — as overviews, tables, mindmaps or timelines — and files them into a searchable personal knowledge base.

Overview

What is Briefy?

Briefy is an AI knowledge assistant built around a single promise: turn any long piece of content into a structured summary, then keep that summary somewhere you can find it again. It handles web pages and articles, YouTube videos, PDFs and uploaded documents, Gmail threads and podcasts, and returns the result in four interchangeable views — overview, table, mindmap and timeline — any of which can be regenerated in a different view once the summary exists.

The tool runs on large language models, and the vendor is explicit that no ChatGPT or OpenAI account is needed on the user's side. It reaches the reader through three surfaces: a Chrome extension for desktop, a Safari extension covering iOS, iPadOS and macOS, and an Online Summarizer on the web for anyone who would rather not install anything. Inside the browser, a magic button activates by itself when a page, a Gmail thread or a YouTube video opens, so the first summary takes one click and no configuration.

What separates Briefy from a plain summariser is the Knowledge Base. Saved summaries become Briefs that can be reviewed, adjusted, searched through Universal Search, questioned with follow-ups, and shared or unshared in a click. Every summary also links back to the source material, so a claim can be checked rather than trusted. Output language is configurable, inline translation is available, and paid tiers raise the ceiling to two million words of text and 50 MB documents.

Usage runs on credits: 30 free every month, 700 on Premium, 1500 on Ultra, with a faster response speed above the free tier. The audience the site names is students and academics, professionals buried in reports and email, and content creators doing research.

One fact frames everything else. Briefy was acquired by Xmind, announced on 21 January 2025, and both the App Store and the Chrome Web Store now publish it under Xmind Ltd. The pricing page carries a matching notice: new subscriptions and credit purchases are no longer available. The free tier still works; the commercial path is closed.

What it does

  • Summarise YouTube videos and extract their key ideas in seconds.

Trust & Privacy

Data, GDPR & hosting

A consolidated view of how Briefy handles your data.

GDPR overview

Implementation is partial but real. The privacy policy, last updated 17 May 2024, carries a dedicated EU and UK section setting out the legal bases relied upon: consent, performance of a contract, legitimate interests, legal obligation and vital interests. Residents of the EEA, the United Kingdom, Switzerland and Canada are granted access, rectification, erasure, restriction, portability, objection and the right not to be subject to automated decision-making, with consent withdrawable at any time. Complaint routes are named: the member state supervisory authority, the UK ICO and the Swiss Federal Data Protection and Information Commissioner. Notable gaps remain: no Article 27 EU representative is designated, no DPO is named, no DPA is published, hosting is United States only, and compliance is never claimed in so many words. Every request goes to a single address, hello@briefy.ai.

Who owns the data?

Briefy's Terms state that private content provided by users stays private: it is neither shared with third parties nor accessed by the vendor without the user's explicit consent. Everything Briefy itself publishes remains the property of the vendor or its licensors, all rights reserved. Personal data collected is limited to email addresses, names, usernames and passwords; no sensitive information is processed and nothing is gathered from third parties. Payment details never reach Briefy, since Lemon Squeezy handles and stores them. Accounts can be terminated on request, after which data is removed from active databases, with limited retention for fraud prevention and legal obligations.

Reuse rights

The Terms reserve all intellectual property in Briefy's own content: users may not copy, download, share beyond the permitted limits, modify, translate, publish, sell, sublicense or create derivative works from it, and reuse is confined to what proper use of the service implies. Content the user provides is treated differently — it stays private unless the user explicitly consents otherwise. On the vendor's side, personal data is processed to create and authenticate accounts, deliver the service, answer enquiries, send administrative messages, manage orders and payments, request feedback, prevent fraud and comply with law, on the GDPR bases of consent, contract, legitimate interests, legal obligation and vital interests. Named recipients include Google Cloud Platform, Amazon Web Services, Google Cloud Storage, Lemon Squeezy, Google Sign-In, Sign in with Apple, Google Analytics, Google AdSense, Sentry and, for AI processing, OpenAI, Anthropic and Google Cloud Platforms. Briefy states it has neither sold nor shared personal data in the preceding twelve months. Data drawn from Google Workspace APIs is explicitly not used to develop, improve or train generalised AI or ML models; no equivalent commitment covers other summarised content.

Data retention & training

Retention summary
Briefy keeps personal data only as long as needed for the purposes set out in its privacy policy, unless a longer period is required by law for tax or accounting reasons. The policy sets an explicit ceiling: no purpose justifies keeping personal data beyond the period during which the user holds an account. Identifier data is retained for the life of the account. Once there is no legitimate business need, data is deleted or anonymised; where that is impossible, for instance in backup archives, it is stored securely and isolated from further processing until deletion becomes possible. Accounts can be closed on request, with data removed from active databases, though limited information may be kept to prevent fraud, resolve disputes, assist investigations and meet legal obligations. No retention period is expressed in days or months.

Hosting summary

Briefy states plainly that its servers are located in the United States, and acknowledges that users outside the country are transferring data internationally when they use the service. The policy notes that the EEA, the United Kingdom and Switzerland may have more comprehensive data protection laws than the jurisdictions the data reaches, and undertakes to protect it in line with applicable law. Infrastructure is supplied by Google Cloud Platform, Amazon Web Services and Google Cloud Storage. The domain resolves to 3.220.105.9, an Amazon address geolocated to Ashburn, United States, which is consistent with that claim. No alternative region is offered, no EU data residency option exists, and no hosting certification such as SOC 2 or ISO 27001 is claimed anywhere on the site. European users should therefore assume United States hosting with no choice of location, and no published Data Processing Agreement to govern the transfer.

Watch-outs

Things to keep in mind

Risks and trade-offs to weigh before adopting Briefy.

  • Summarising is not reading: leaning on Briefy for material you must genuinely master can leave you with the shape of an argument and none of its substance.
  • AI summaries can distort or omit; the link back to source content exists precisely because the output should be checked rather than trusted.
  • The tool was acquired by Xmind in January 2025 and new subscriptions are closed, so any workflow built on it should be treated as provisional.
  • Content you summarise is processed by third-party AI providers named in the privacy policy (OpenAI, Anthropic, Google Cloud Platforms): avoid pasting confidential material.
  • There is no documented way to exclude your content from model training, beyond a narrow clause covering Google Workspace API data.
  • All data is hosted in the United States, a transfer European users should weigh before adopting the tool.
  • Google AdSense sits among the third parties receiving data, so advertising is part of the service perimeter.
Setup

Setup & Integrations

Technical difficulty

Very low. Installation takes a few clicks from the Chrome Web Store or Apple's App Store, and an account is required — Google Sign-In and Sign in with Apple are both available. No server configuration and no API key are involved. The magic button activates by itself when a page opens, so the first summary needs no settings at all. Anyone preferring not to install anything can use the Online Summarizer on the web. Apple users need iOS or iPadOS 16, or macOS 13 on an Apple M1 chip or later. No technical skill is required.

Conclusion

Should you pick Briefy?

Briefy does one thing well and does it with more care than most: it compresses long reading into a structured summary, then refuses to let that summary evaporate. The four views are a genuine differentiator — a mindmap of a dense research paper is a different object from a paragraph of prose, and several reviewers single it out. The Knowledge Base, Universal Search and the link back to source content turn a throwaway summary into something closer to a personal research archive. For students, academics, analysts and content researchers working through heavy reading loads, the free tier alone — 30 renewable credits a month, no card — justifies the install.

The reservations are real, and mostly structural rather than functional. Video is limited to YouTube and requires subtitles. Several advertised capabilities, including the Gmail extension and audio or video file summarisation, have carried a Coming soon label without shipping. Data governance is thin: hosting is United States only, there is no published DPA, no Article 27 EU representative, no named DPO, no security certification, and no documented way to keep your content out of model training beyond a narrow Google Workspace clause. A single generic mailbox handles legal, GDPR and support alike, and no postal address appears anywhere on the site.

Above all, Briefy has been acquired by Xmind, and its pricing page now states plainly that new subscriptions and credit purchases are no longer available. The privacy policy has not been revised since May 2024, and the blog has been silent since the acquisition post. The product still runs and the free tier still delivers, but anyone considering it should treat it as a capable tool in a holding pattern rather than one on an active roadmap.
