Long-form guides — start at the overview or open any chapter

What a neural network and generative AI are in plain words: how they create text, images, video, music and speech. Free generators, ChatGPT and its rivals — with live examples on the page.

How neural networks create and edit pictures: from text-to-image to face swap and object removal. Model breakdowns and live examples right on the page.

How neural networks create video: animate a photo, text to video, a talking avatar, translation and subtitles. Breakdowns of Sora, Kling, Runway and live examples on the page.

Upload a short clip and say what to remove — a person, an object, a caption. How it works without blur, what comes out clean and what does not.

How neural networks compose music: a track from a description, a song with vocals, beats and backing tracks, genres and copyright. A look at Suno and alternatives, with live examples on the page.

How neural networks voice text, change and clone voices, and transcribe audio. A look at ElevenLabs and alternatives, with live voice-over examples right on the page.

How to transcribe with AI: timecodes and speaker labels are taken from the audio itself. What drives accuracy, which files and lengths work, and what it costs.

How to make a presentation with AI: from a first draft in a minute to slides from text and documents, a pitch deck for investors and slide design. With live examples on the page.

How to make a product card with AI: backgrounds and photos without a studio, infographics, titles and descriptions for in-platform search, Wildberries and Ozon requirements. With live examples on the page.

How to gather keywords and read demand with AI: query statistics, keyword selection and the semantic core. Wordstat is built into the chat — no separate tab.

How to build ads with AI in one chat: demand analysis, offers and copy, posts and a content plan, image creatives and video. One tool instead of five — for SMM, agencies and small business.

How to make a card and write a wish with a neural network: from a photo, for birthdays and holidays, text in verse or prose, a video card. Make the picture right on the page.

How to use AI for studying honestly: a plan and structure, a draft, finding sources and checking your own text. Essays, reports and projects — faster, but still your own work.

How to draft work documents with a neural network: a resume and cover letter, business letters and a business plan. A ready structure and text in minutes — just add your facts.

How to analyse documents with a neural network: upload a PDF, scan or report and get a short summary, extracted data and answers to questions about the content. Financial statements, contracts and long PDFs — in minutes.

An honest comparison of neural networks: a rating by task, alternatives to ChatGPT, Midjourney and Suno, what works without barriers and what it costs. Tables, real numbers and FAQs.

How to connect a coding agent — opencode, Cline, Kilo Code, Roo Code, Cursor — to an OpenAI-compatible API. Setup, models, token prices and troubleshooting.

What MCP (Model Context Protocol) and an MCP server are, how MCP differs from an API, local vs remote servers, and how to connect MCP to Claude, Cursor, LM Studio, Codex and OpenCode.

How to sell an item on Avito fast: photos, title, description, price and replies. A one-minute listing check and ready tools right on the page.

What an AI agent is and how it differs from a chatbot, what an agent is made of and how to build one without code: an interactive diagram, a step-by-step example and ready agents.

What an AI character is made of, and why one holds its role while another turns back into an assistant after five replies. Characters you can talk to right on the page.

Twenty seconds of audio and the voice is saved — after that it reads any text, up to 10,000 characters at a time. What to record and where consent draws the line.

Light and colour come from the file; sharpness on a blurred face and pixels on an enlargement are invented. Six different jobs behind one phrase, and where the limit is.

What actually happens to your photo, which frames animate cleanly, how to word the request, and why clip length is the only setting that really moves the price.

A breakdown of the models that actually run in Twelver: GLM, Nano Banana, Qwen, Seedance and more. What each does, how it differs from its neighbour, and how to try it on the page.

What AI actually does with text: writes, rewrites, shortens and checks it. What it costs, with live rates on the page, where it makes things up, and how Russian differs from English.

Can AI build a website? Yes — a single page: a landing page, a business card site, a calculator. How it works, what to write in the prompt, what is free, how it differs from Tilda and Wix, and what AI still can’t do.
Five AI chat workflows professionals use to cut hours out of the week — sharper prompts, reusable agents, batch drafting and handoffs that actually stick.
PremiumA step-by-step guide to handing repetitive work to an AI chat assistant: pick the tasks worth automating, write the prompt once, then reuse it every day.
Connect your Twelver account to VS Code extensions like Kilo and Cline: generate an API key, point the extension at the OpenAI-compatible endpoint, and code.
