AI Apps

AI apps for Claude, ChatGPT
and AI agents.

Built for our clients, published on the Apify marketplace so anyone can run them: in your AI assistant, in one sentence, or on Apify in a form. Each app gives a free estimate of its price before anything runs.

What these apps are

Lexonia builds apps on Apify. Apify is a marketplace of apps for AI, an app store where assistants and agents find the tools they need. Our apps live there under one account: apify.com/lexonia.

Why apps. AI platforms like ChatGPT and Claude are very powerful brains. Apps are what let those brains go above and beyond: read a video in another language, search a whole market, find the one contact that matters. Connect an app to your assistant and the job is done in a sentence.

Why these apps. We have been particular about what to build. Most of our apps come from practical use cases our clients brought us: find the people my customers listen to, read what is said about my market in a language I do not speak, give me every business of a kind in a city. We publish them so anyone can run them.

We keep working on other apps. Here are some of the key ones we would like to share.

Video Lens

Transcribe and translate videos from YouTube, TikTok, Reels, Bilibili, Douyin and Vimeo.

Paste a video link from YouTube, TikTok, Instagram or Facebook Reels, Bilibili, Douyin or Vimeo, or a whole YouTube, Bilibili or Douyin channel. You get the transcript in its own language, a translation into any of 32 languages and a summary, plus subtitle files for YouTube, TikTok and Bilibili. No captions needed; it listens to the speech.

Why it matters. Much of what your market says lives in video, in a language you may not speak. Selling into China? Read what Chinese buyers watch on Bilibili and Douyin, in English. Working from China, or anywhere else? Read what Americans, Japanese or Italians are watching, in your own language. YouTube’s official API hands out caption files only for videos you are allowed to edit; Video Lens reads public videos on every platform above.

What people have used it for

  • A real estate company in London wanted the YouTube channels on travelling to and investing in Cyprus that UK and German travellers and investors watch. Audience Intel found the channels; Video Lens turned their videos into transcripts, the German ones translated into English, for the marketing team to build its strategy on.
  • An AI model developer got English summaries of what Chinese developers watch on Bilibili and Douyin about building local models on Qwen and DeepSeek.

Audience Intel

Find the YouTubers and opinion leaders your customers already watch, with a way to reach each one.

Describe your audience in your own words. You get the YouTubers and opinion leaders those people watch on YouTube, TikTok, Bilibili and Douyin, ranked, each with the contact they publish. A free estimate shows the search plan and the price before anything runs.

Why it matters. The opinion leaders your customers trust already have their attention. Reach out with the contact in hand and build a partnership: a co-marketing campaign, a sponsored video, or a revenue-share deal where the opinion leader earns from every customer they send you. The app finds the people; the deal is yours to shape.

What you can use it for

  • Launching where the fans already watch. A robotics start-up in Seoul is about to show its first humanoid robot. A press release would vanish in a busy week of tech news. The people who care follow a few Korean YouTubers who cover robots in depth. Audience Intel ranks those YouTubers, each with a contact, so the start-up can invite them to film the robot first and let their viewers see it before anyone else.
  • Selling through people your customers trust. A skincare brand in the US is tired of paying for ads that get scrolled past. Its buyers learn their routines from a few YouTubers and TikTok opinion leaders. Audience Intel ranks them, each with a business email, so the brand can offer them a revenue share: a code for their followers and a cut of every sale they bring in.

Business Finder

Built for lead generation: the businesses of one kind in a city, a state or a region, with phone and contact.

Searched in the local language too, so a search in Warsaw or Bangkok finds what an English search misses.

Why not just Google? Google Maps shows places one at a time on a map, for you to browse and copy by hand. Business Finder uses the same Google data and hands you the whole list as one table, searched in the local language, with the contact from each business’s own website, an optional mailbox check and reviews by period. Built for outreach, not browsing.

What you can use it for

  • Entering the US market. A medical device maker in South Korea has a new patient monitor cleared for sale in the US and no contacts there. It needs distributors, not hospitals. Business Finder lists the medical equipment suppliers in Texas, then state by state, each with phone, website and the contact from its own website. The sales team starts calling in week one instead of buying a list.
  • Winning bigger contracts. A landscaping company in Minnesota wants year-round work beyond homeowners. Commercial contracts come through property managers. Business Finder lists the property management companies across the Twin Cities, biggest first by number of reviews, each with phone, website and the contact from its own website. The owner calls the top twenty before the spring contracts are signed.
