A calendar that publishes posts to more than 30 social networks: X, LinkedIn, Instagram, TikTok, YouTube, Reddit, Bluesky, Discord and others. The whole code is open source, so anyone can run it on their own server for free; the company sells the hosted version from US$29 a month. Since 2025 AI agents such as Claude, ChatGPT and OpenClaw can connect to it through an MCP server, a command-line tool and a public API, so an agent drafts and schedules the posts and a person approves them in the calendar.

The founder took a twenty-year-old product category with no open-source entry and open-sourced all of it, which gave him millions of Docker downloads and 37,000 GitHub stars without a marketing budget. Revenue stayed small for a year. It multiplied when he turned the product toward people who automate their posting with n8n workflows and, from late 2025, with AI agents, which need an API-first scheduler and keep paying because they post without human effort.

An AI agent for paid advertising that works inside ChatGPT, Claude, Claude Code, Cursor and other AI assistants. It connects to the customer's ad accounts at Google, Meta, LinkedIn, TikTok, Amazon and ChatGPT Ads, researches keywords, builds campaigns (always created paused), reports results and finds wasted spend. Scheduled agents can also watch the accounts and make reversible changes. The customer pays the ad platforms directly.

It went where the users already were: an app in ChatGPT's app store, a plugin in Claude's directory and in Claude Code, and setups for Cursor and Codex, in the months when these directories were new. It charges per tool call instead of a share of ad spend, so a small advertiser starts at US$49 a month. And it applied to the platforms' own API programs; the company says Google approved it in June 2026 and Amazon admitted it to its partner network.

A LinkedIn lead finder for B2B sales teams. You list LinkedIn profiles to watch; traxy collects the people who like, comment on or repost their posts, scores each one against your ideal buyer, adds an email address and phone number, and an AI agent can write and send the first message.

The founder already ran a LinkedIn ghostwriting agency and built the lead tool that the agency needed. He sold it with the tool itself: traxy found the leads, and his team contacted them. Daily posts on X added trials, and credit-based prices let heavy users pay more.

An AI assistant that you reach by message. You send a voice note, a text, a screenshot or a forwarded email on WhatsApp, Telegram, iMessage, Slack or email, and it writes notes, tasks, draft posts and CRM updates into Notion and more than 1,000 other connected apps. It started as a voice-to-Notion tool. In 2026 it added a desktop app, a cloud computer, automations, and connections to Claude, ChatGPT and coding agents.

It reached people inside the chat app that they already open all day, so capturing an idea on a phone took one voice note. It aimed first at Notion users, whom the company told that ideas get lost on the phone. Ads on Facebook and Google then paid for fast growth in early 2026, until the founder stopped them in August 2026 because the costs were larger than the revenue.

A company connects My AskAI to the help desk it already uses, such as Intercom or Zendesk, and gives it the help center, the website and past tickets to read. The agent then answers customer questions inside that help desk, or writes a draft as an internal note for a human agent. When it cannot answer, it hands the conversation to a person in the same tool, with a summary.

The founders sold the idea before they built it, and built it with a no-code tool so that one person could change it every day. Then they cut the product down to the one use that brought 70% of the revenue. They placed it inside the help desks that customers already pay for, and priced it below the AI agents that the help-desk vendors sell themselves.

A Chrome extension that adds folders, full-text search, a prompt library, bookmarks and export in four formats to the web pages of ChatGPT, Gemini, Claude and Grok. It sells no AI: users keep their own accounts, and the search index of their chats stays in their browser.

Heavy users of AI chat apps lose old answers, because the apps had no folders, no filtered search and no bulk export. AI Toolbox adds these inside the apps, for four apps at once, sells them mostly as one-time licenses, and, by the seller's account, finds its buyers through search pages instead of ads.

A user gives a topic, a text, a PDF, a web address or a YouTube link, and a language model writes a slide presentation from it. MagicSlides runs as an add-on inside Google Slides and as a web application that exports editable PowerPoint, PDF and Google Slides files. Since July 2026 the same account also includes AI tools for spreadsheets, documents, meeting notes and a design canvas, under the name Magic Suite.

It appeared in January 2023 inside Google Slides, a program where people already work, when writing slides from one sentence was new, and users showed it to each other without paid advertising. A blog about presentation topics then brought about 80% of new users from Google search, by the founder's account. Both channels weakened: search traffic fell, and Google added the same function to Slides. The verified total is real, and so is the fall: monthly revenue fell by half between February and July 2026.

A web application for people who sell simple books through Amazon's Kindle Direct Publishing. The user describes a book, and AI models produce its pages: line drawings for coloring books, puzzles and mazes for activity books, text and layouts for journals and planners, and a description for the Amazon listing. A subscription buys credits. By the terms of service one generated image costs 200,000 credits, so the smallest plan, with 40 million credits a month, pays for about 200 images.

It sold one narrow job to a group that already existed: people who learn from YouTube channels and paid courses how to publish many simple books on Amazon. The product carries that group's own word in its name, tutorial channels in English and Italian showed it from January 2025, and the site runs an affiliate script. Two thirds of the US$642,409 came in the first 14 months, at about US$30,300 a month. The last 12 months average about US$17,600 a month.

A web app that writes LinkedIn posts in the member's own style from an idea, a voice note, a video, an article or a short interview with an AI, then schedules and publishes them. Team plans add approvals, a shared calendar and analytics for each employee. It can also be used from inside Claude and ChatGPT.

It entered a market where people already paid for tools such as Taplio, and did the one core task better: writing the post. The founders' public posts brought the first customers and a lifetime-deal platform, and that deal paid for growth without investors. Subscriptions, partnerships with LinkedIn influencers, affiliates and a move to team plans came after.

You describe an app in plain language. Base44 generates a working web app with its own database, user login and hosting, so you never touch a server.

It launched in the month that AI models became good enough to write a whole app. It sold to people who cannot program, it charged from day one, and it was sold to a company that already had millions of customers.

An iPhone app for makeup. The user uploads a selfie without makeup and a photo of a makeup look, for example from TikTok or Instagram. The app's AI applies that look to the user's own face, then gives a step-by-step routine and a list of products to buy. It is free to download and paid for with subscriptions through the App Store.

Its result is a before-and-after picture of the user's own face, which a short video shows in seconds. The founder chose TikTok as the channel before he built the app, then tripled revenue from almost the same installs by moving and testing the paywall with Adapty.

A web app for real estate agents and photographers. The agent uploads a photo of a room, chooses the room type and a furniture style, and gets back the same room with furniture in about 10 to 15 seconds. It can also remove existing furniture. Plans are monthly subscriptions sized by the number of photos, and the top plan includes an API.

In 2023, general image generators that were asked to furnish a room also changed the room: the founder said DALL-E might turn a window into a wall painting or add a door, which misrepresents a property. VSAI's own model finds the floor, the ceiling, the mirrors and the doors first and only then adds furniture. It cost US$12 to US$69 a month in early 2024, while VSAI's comparison page lists other staging services at US$16 to US$29 per photo with 12 to 48 hours of waiting. Zillow, the listing portal where such photos end up, bought it.
