AI Toolbox is a browser extension, a small program that runs inside the Chrome browser and can add buttons and panels to the web pages you open. It adds folders, bookmarks, a prompt library, export to text, Markdown, JSON and PDF, and full-text search, which means search in the words of every message and not only in chat titles, to the web pages of ChatGPT, Gemini, Claude and Grok. It does not sell an AI model: users keep their own ChatGPT, Google, Anthropic or X accounts. The free plan has small limits. A paid plan for one AI app costs US$9.99 a month, US$59 a year or US$99 once, and all four apps cost US$199 once.

Two developers, Adi Leviim and Mohammad El-Esawi, released it as ChatGPT Toolbox on the Chrome Web Store in September 2024 through their two-person company, Infi Developments. It had more than 8,000 users in February 2025. In April 2026 it added Gemini, Claude and Grok and took the name AI Toolbox, and in October 2026 the store shows 40,000 users. TrustMRR, a site that reads a seller's sales directly from the payment provider (the service that charges the buyer's card) through an API key (a password that lets one program read another program's data), shows US$108,506 of revenue in the 12 months to 14 October 2026, from Lemon Squeezy and Polar, and US$22,302 in September 2026 alone. The pricing page calls the lifetime license, one payment for permanent use, its most popular plan, and about 94% of the last 30 days of revenue does not repeat monthly. So the MRR, monthly recurring revenue, the subscription money that repeats every month, is only US$1,334.

The revenue figures are grade A. The costs, the margin, the working hours and the claim of no advertising are the seller's own words, grade C, and this page marks them as claims. Adi Leviim has listed the business for sale on TrustMRR since January 2026, asking US$800,000. The page also shows what happened to earlier companies that added order and search to a platform that they did not own.

03

Why it worked

Four causes, in the order they mattered. Each one is a reusable lesson.

01

Features the AI apps did not have

By the company's account, in mid-2024 ChatGPT had no folders, no search filters by date or role and no bulk export, and heavy users kept hundreds of chats. The extension added these inside ChatGPT's own sidebar, so users kept their habits and their AI subscription.

02

One set of tools for four AI apps

In April 2026 the Gemini, Claude and Grok modules joined ChatGPT in one install. Each paid plan covers one app, and All Access covers all four for US$199 once. One search box, one folder tree and one prompt library work across all four, which no single AI company offers.

03

One-time prices

A lifetime license costs US$99 per AI app, about ten months of the US$9.99 monthly price. TrustMRR counts a one-time payment as revenue in the month it arrives, but MRR counts only subscriptions. That is why the last 30 days brought US$21,509 while MRR is US$1,334.

04

Search pages instead of ads, by the seller's account

The seller says growth comes only from a website written for Google and for AI answer engines. The Wayback Machine first saved 168 pages of the site in all of 2025, and 607 new pages from July to September 2026, the quarter in which revenue was 2.05 times the quarter before (calculated). The site also publishes an llms.txt file, a plain-text summary written for AI models. Three Product Hunt launches, X accounts and a subreddit add to it.

How it was built

These details come from the company's own pages and from the tech list on its TrustMRR profile, which the founders filled in. They are grade C. [1, 7, 2, 5, 4]

  • The TrustMRR tech list names Next.js, TypeScript and Sass for the front end, and Node.js, Express, MongoDB, Redis, Nginx, DigitalOcean, Cloudflare, GitHub Actions and Resend for the back end.
  • The extension keeps a copy of the user's chats in IndexedDB, a database built into the browser, and runs search and automatic topic tags on the user's device.
  • Folders, saved prompts, bookmarks and settings are stored on the company's servers, encrypted at rest, so that they follow the user to other devices.
  • Three features, PDF export, pulling a long chat into a new one, and carrying a chat to another AI app, send the text of one chosen chat to the servers. The two summary features pass that text to the OpenAI API.
  • Payments went through Lemon Squeezy and now go through Polar; some old subscriptions are still billed by Lemon Squeezy. A purchase is matched to the user's AI account by email address.
  • Version 5.0.0 came out in April 2026 and version 5.0.54 on 14 October 2026. Since late August 2026 the extension can show notices to users without a store update.

The dead that came before

Five companies in the Loot Drop database added order, search or sync on top of a platform that they did not control. The values below are from that database and are not independently verified.

Died 2006 to 2013Burned US$42M

Xobni

The promise

Search and contact tools inside Microsoft Outlook.

Why it died

Tied to one email program. Microsoft improved Outlook itself and users moved to phones. Yahoo bought what was left.

Died 2006 to 2014Burned US$9M

Xmarks

The promise

Sync bookmarks and tabs across browsers and devices.

Why it died

Chrome, Firefox and Safari built sync in, for free.

Died 2009 to 2015Burned US$5M

Readability

The promise

Clean reading of any web article, without ads and clutter.

Why it died

Browsers added a free reader mode, and few readers paid.

Died 2012 to 2016Burned US$8M

Sunrise

The promise

One calendar app for calendars from Google, Microsoft and others.

Why it died

Microsoft bought it in 2015 and closed it a year later, moving its features into Outlook.

Died 2012 to 2017Burned US$400K

Kippt

The promise

A bookmarking tool to save, organize and share web content.

Why it died

Pocket and Evernote did the same job, and its sharing features did not bring new users.

What changed

Each of the five added order, search or sync to something that it did not own: Outlook, the browser, web articles, calendars and bookmarks. Each raised venture money and had to become large. Then the platform built the feature itself, or a bigger company bought it or did the same job, and the add-on lost its reason to exist. AI Toolbox makes the same bet on ChatGPT and three other AI apps, and OpenAI has already added Projects to ChatGPT.

Three things differ. Two people run it without outside money, so, by the seller's account, it makes a profit at a size at which the predecessors could not have survived. It covers four AI apps, so one platform change does not end it, and its search and folders across all four apps are something no single AI company sells. And it took its money early, through one-time licenses: that made it profitable quickly, but it leaves a long support promise to whoever owns it next.

05

Can one person copy it now?

The method, yes. This niche, only with care.

Two developers built more than US$100,000 a year of revenue by adding the missing parts of AI chat apps, with no outside money and no servers that store the chats. The method is repeatable: find what heavy users of a fast-growing web app keep asking for, build it inside that app, and sell it once at about ten months of a subscription. The niche itself is now crowded: one comparison tested 25 ChatGPT extensions in August 2026, and the AI apps keep adding folders and projects.

Where it is still open: New AI apps with heavy users and weak history tools: AI search engines, AI image and video generators, voice assistants, and the web versions of AI coding tools.

  1. 1Read the reviews and forum posts of a fast-growing web app, and list the features that its heavy users ask for and do not have.
  2. 2Build those features inside the app's own page, and keep the user's data in the browser so that server costs stay small.
  3. 3Offer a free plan with small limits, a monthly price, and a one-time price of about ten months of the monthly price.
  4. 4Write one help or comparison page for each question that users type into search engines, and publish an llms.txt summary for AI answer engines.
  5. 5When a second and a third app grow, add a module with the same features and sell one bundle for all of them.

What to watch

The risks are the mirror image of the causes above.

It lives inside other companies' web pages

The extension adds buttons and panels to the pages of ChatGPT, Gemini, Claude and Grok. The company's changelog says these apps change their interfaces without notice and that a change can hide a button the extension attaches to; its terms say such changes may affect features temporarily or permanently. It also depends on the Chrome Web Store, whose policies say Google may change them at any time.

The AI apps add the same features

OpenAI's help center describes Projects in ChatGPT, which group chats, files and instructions and can take old chats with a Move to project option; the Wayback Machine has a copy of that article from June 2025. Three of the five predecessors on this page lost to a platform that built the feature itself. AI Toolbox's answer is search, folders and export across four AI apps at once.

Lifetime plans are paid once and supported for years

About 94% of the last 30 days of revenue does not repeat monthly. The terms promise lifetime buyers all future updates, and All Access buyers every new AI app the extension adds, for as long as the extension works. Each lifetime buyer adds support work for years while the money arrives once. The seller names turning one-time plans into subscriptions as a task for a buyer.

Extensions that collected AI chats

In December 2025 The Register and The Hacker News reported Koi Security's finding that Urban VPN Proxy and three other extensions, with more than 8 million users, had collected people's prompts and answers on ChatGPT, Claude, Gemini, Grok and other AI apps since July 2025, and that the data was sold for marketing. One of them had a Featured badge from the Chrome Web Store. AI Toolbox reads the same pages. Its privacy policy says chats stay in the browser, except for short previews of bookmarked messages and three features that send one chosen chat to its servers, two of them on to the OpenAI API for a summary. So the listing's line that no chat content leaves the browser says more than the policy does.

For sale, with access to users' browsers

The business has been listed on TrustMRR since 14 January 2026 at US$800,000, with 6 offers, and was still listed after 273 days (calculated to 14 October 2026). A buyer would take over an extension that about 40,000 people let read their AI chat pages. The Register notes that the store's Limited Use policy allows user data to move when a business changes owner.

Seller numbers that this page could not check

The margin, the costs under US$100 a month, the 5 hours a week, the zero ad spend, the 1,700 paying customers, the 47,000 monthly users and the 23,000-member subreddit are the seller's words. The listing also says revenue grew from US$2,900 a month in May, but the verified table shows US$6,942 for May 2026; US$2,869 is the figure for November 2025.

The growth is recent

Calculated from TrustMRR: 77.5% of the 12-month revenue came in the last 6 months and 51.5% in the last 3 months. The verified history is short, and it depends on new one-time sales every month.
