AI Summary for YouTube
A free Chrome extension that generates an AI text summary of any YouTube video in seconds, displayed beside the player, with one-click transcript copying. No AI account and no API key are required to use it.
What is AI Summary for YouTube?
AI Summary for YouTube is a Chrome extension published by LELU TECH LTD, a software development startup based in Hong Kong. Its scope is deliberately narrow: install it, open a YouTube video, and after a few seconds a text summary of that video appears in a panel to the right of the player. The full transcript can be copied in a single click. Nothing else is on offer, and nothing else needs configuring.
The selling point is the absence of setup. Unlike most summarisers, this one asks for no AI account and no API key of your own — the publisher states that all functionality is built in and self-contained. The consequence is that the AI model doing the work is never named, and neither is its provider.
Technically the extension is a manifest v3 build whose content scripts run only on www.youtube.com. It requests host access to youtube.com and to the publisher's own domain, plus the storage, tabs and webRequest permissions. Version 2.1.2 shipped on 4 June 2026 and weighs 675 KiB. Documented changes trace a maintained product: 2.0.5 restored compatibility with Chrome 130, 2.1.0 added support for Shorts pages, and 2.1.1 renamed the extension — the domain chatgpt4youtube.com and the Product Hunt listing still carry the earlier name, ChatGPT for YouTube.
Adoption is real but satisfaction is middling: the Chrome Web Store reports 100,000 users and a rating of 3.1 out of 5 across 110 reviews, in the Workflow & Planning category. The interface exists in four languages — English, Portuguese, Russian and Turkish. First publication was 2 March 2023, a week after the domain was registered.
Commercially it is a quota system. Seven summaries a week are free and permanent; beyond that you buy a pack of credits or take an unlimited subscription, managed from the account page. The publisher describes its own business model plainly as generating profit through software subscriptions. The video types it names are courses and tutorials, news, product feature introductions, interviews and academic seminars.

How to use AI Summary for YouTube
A typical end-to-end flow, from setup to results.
- Open the Chrome Web Store listing from the Add To Chrome button on the homepage
- Install the extension in Chrome, accepting the storage, tabs and webRequest permissions
- Open any YouTube video — a standard video page, or a Shorts page since version 2.1.0
- Wait a few seconds: the summary appears on its own in the panel to the right of the player
- Read the summary to judge whether the video is worth watching in full
- Copy the transcript in one click if you need the complete text rather than the digest
- Once the seven free summaries for the week are used up, sign in through the Get Started button
- Buy a credit pack of 300 or 1,000 quotas, or take out the unlimited monthly subscription
- Manage or cancel the subscription from the profile page, using Manage Subscription
- No API key ever has to be pasted in, and no third-party AI account has to be connected
Pros & Cons
Pros
- Nothing to configure: no API key to obtain and no AI account to connect before the first summary
- A permanent free tier of seven summaries per week, with no payment card mentioned
- The summary is delivered in place, beside the player, without leaving YouTube
- The full transcript can be copied in a single click
- A genuine installed base of 100,000 users on the Chrome Web Store
- Actively maintained, with version 2.1.2 dated 4 June 2026 and a documented change history
- Permissions are narrower than most: content scripts are confined to youtube.com rather than every site
Cons
- A rating of 3.1 out of 5 across 110 reviews places it in the lower half of the store's scale
- Scope is confined to YouTube and to Chrome: no Edge or Firefox build, no mobile app, no other video platform
- No GDPR mention in any document, no DPA, no named subprocessor and no published retention period
- One channel for everything: a personal Gmail address serves support, legal and privacy alike, and the Support page is only a feedback form
- The AI model behind the summaries is never identified, so where the video content is sent cannot be established
- Advertising cookies are announced in both privacy policies with no documented consent mechanism
- Legal documents are split across two domains and inconsistent with one another, one of them frozen at a 2024 copyright

Data, GDPR & hosting
A consolidated view of how AI Summary for YouTube handles your data.
GDPR overview
There is no GDPR implementation to report. The words GDPR, General Data Protection and CCPA appear nowhere across the ten pages collected, in either the rendered text or the archived HTML. No Article 27 representative is designated, no data protection officer is named, no lawful basis for processing is stated, no retention period is given and no international transfer is described. The closest equivalent is section 6 of the company privacy policy, which recognises rights of access, rectification, erasure, objection and restriction, exercisable by email to the single contact address. On the Chrome Web Store the extension declares that it handles personally identifiable information, while the publisher registers as a non-trader and notes explicitly that EU consumer rights do not apply. Both privacy policies announce cookies serving personalised content and advertising, with no consent mechanism documented anywhere.
Who owns the data?
Neither the user agreement nor either privacy policy says who owns the summaries the tool produces: ownership of generated content is simply not addressed. What the documents do cover is personal data. LELU TECH states that it collects a name, email address, phone number and contact details, along with IP address, browser type and pages viewed in log files. It undertakes not to sell or rent personal information, but reserves the right to share it with unnamed trusted partners who help operate the service under confidentiality agreements, and to disclose it where the law requires. The Chrome Web Store listing adds that the data is not sold to third parties outside approved uses. No third party is ever named — neither those trusted partners, nor the provider of the AI model that writes the summaries.
Reuse rights
The user agreement grants the end user no explicit reuse rights over the summaries and transcripts produced, and withholds none either: the question is absent from the document. The only restrictions it sets concern the user's own conduct — no illegal activity, no infringement of other people's intellectual property, and no dissemination of false or misleading information. That last clause matters in practice, because the source material belongs to the YouTube creators rather than to LELU TECH, and nothing in the published documents addresses the status of a derived summary or of a copied transcript. Users should also note that the publisher reserves the right to modify or terminate the service at any time, which extends to continued access to summaries already generated.
Data retention & training
Hosting summary
No hosting jurisdiction is declared anywhere on the site. Neither privacy policy names a country or region where data is stored, the user agreement states no governing law, and no international transfer clause or standard contractual clause is mentioned. The only measurable element is technical rather than contractual: on 9 August 2026 the A record for chatgpt4youtube.com resolved to 3.165.190.78, an Amazon Web Services address geolocated to Zurich, Switzerland. That is a delivery node, not a declared place of storage, and it should not be read as a hosting jurisdiction. The publisher, LELU TECH LTD, is based in Hong Kong, which says nothing about where data sits. The extension's privacy policy claims reasonable security measures without describing a single one, and expressly declines to guarantee security. No certification is claimed: SOC 2, ISO 27001 and encryption appear nowhere in the pages collected.
Things to keep in mind
Risks and trade-offs to weigh before adopting AI Summary for YouTube.
- The extension requests the storage, tabs and webRequest permissions on top of host access to youtube.com and the publisher's domain: tabs and webRequest grant visibility over browsing across tabs and over network traffic, well beyond reading the page you are watching
- The video content leaves your browser to be summarised, yet neither the AI model nor its provider is ever named, so it is impossible to establish whose hands the text passes through
- Both privacy policies announce cookies used for personalised content and advertising, with no consent mechanism documented anywhere, while the store listing declares that personally identifiable information is handled
- No retention period, no named subprocessor and no DPA: what becomes of your data over time is simply never stated, and the only remedy is an erasure request sent to a single personal Gmail address
- Relying on an automatic summary instead of watching costs nuance, context and tone, and a summary can quietly omit or distort the one point that mattered
- A generated summary is not a verified transcript: quoting it as a source without returning to the video invites error, and the tool's own terms forbid disseminating misleading information
- The declared minimum age is 13, but no verification mechanism is described, and the publisher's non-trader status removes the consumer protections an EU user would otherwise expect
Setup & Integrations
Technical difficulty
Minimal. Installation is one click from the Chrome Web Store, with no configuration afterwards: no API key to obtain and no third-party AI account to connect. No account at all is needed for the seven free weekly summaries — signing in only becomes necessary to buy credits or subscribe. The summary then appears on its own when a video opens, with no action required. The extension weighs 675 KiB. The only real prerequisites are having Chrome, since no Edge or Firefox build exists, and accepting the storage, tabs and webRequest permissions at install time.

Should you pick AI Summary for YouTube?
AI Summary for YouTube is an unapologetically single-purpose tool: it summarises a YouTube video and lets you copy its transcript, and it does nothing else. Judged on that promise, it holds up. The real strength is the absence of friction — no API key to obtain, no third-party AI account to connect, and a permanent free tier of seven summaries a week that requires no payment card. The installed base is genuine at 100,000 users, and the product is maintained rather than abandoned, with three documented releases and the latest dated 4 June 2026.
The weaknesses are contractual rather than technical. No document mentions the GDPR. No retention period is published, no DPA is offered, no subprocessor is named, and the AI model that reads the video is never identified. Advertising cookies are announced in both privacy policies with no consent mechanism described. Support, legal enquiries and data-subject requests all converge on one personal Gmail address, and the publisher registers as a non-trader on the Chrome Web Store, explicitly setting EU consumer rights aside. Store reviewers place it at 3.1 out of 5.
The practical conclusion follows the split. For personal, occasional use on public video — a lecture to triage, a tutorial to skim, a news clip to check — the tool is cheap, quick and reasonably scoped, and its permissions are narrower than many competitors'. For anything involving an employer's procurement process, a compliance review or sensitive material, the documentary gaps are disqualifying, and the fact that they are gaps rather than unfavourable terms does not make them safer. Read the summary, then go back to the video before quoting it.
