Welcome to
Say what you need
Type a question, or press @ and choose where to look: the internet, weather, news, the company register, a map or a part of the app.
Less searching. More work done.
From a blank page to a clear next step.
Write a brief, find sources and work with images in one workspace. DouTok helps turn unfinished ideas into something you can use.
Try the demo chat first. Then decide what you need.
DouTok AI / WorkspaceActual app interface
Captured in the current build. Colors and layout can be customized in the app.
Meet Riha
Your AI, with a little more personality.
Your friendly AI companion in DouTok AI. Explore ideas, talk about your day, or ask her to look something up.
Replies you can hear
Riha reads her reply aloud in English as the text appears. You can stop the voice and the reply at any time.
Explore the web together
Ask for fresh information with linked sources, or share a public webpage for Riha to read.
Hello, I am Riha. It is lovely to talk with you.
This short sample plays instantly. In a conversation, Riha creates her voice on your device.
Available with Starter and higher. Voice replies are currently in English.
What do you need to finish?
Start with what is holding you up.
Three examples of getting from a task to a usable result.
01Sound familiar?
You know what you mean, but the document is still blank.
Outline a customer email: meeting summary, next steps and a deadline.
What you take away
A draft you can edit and send.
Refine the tone, length and context in chat. You review the final text.

How it works
Ask. DouTok goes and looks.
DouTok finds it and reads it
It searches the web through several engines at once, opens the pages and answers with links to its sources. When a source is silent, it says so.
You decide about actions
Reminders, notes and price watches happen only after you confirm. A risk officer checks every action and never writes a password or key anywhere.
What it does
Everything, in one account
All of this is DouTok AI. No add-ons and no second sign-up — and anything still being built says so, here and inside.
Workspace
The full assistant: files, images, your own documents and memory, with sources attached to the answers.
Riha
One voice, nine specialists: a master agent hands your command to news, weather, web, company-register, map and economy experts, reads their answers aloud — and nothing is done without the risk officer's stamp.
Search
Enter a query in DouTok AI and open results directly on Google.com.
World Monitor
The planet, live and without an API key: earthquakes, wildfires, storms, Earth's magnetic field and the satellites overhead, on a 3D globe.
Weather
Forecast, radar and air quality from open data, for anywhere you can name.
Glycaemia
Blood glucose records and educational simulations with Sirael. A simulation does not replace measurements or medical care.
Presentations
Describe the talk and get the deck back, slide by slide, ready to edit.
Mini-Games
Quizzes, adventures, polls and matching games, made from a sentence.
Games
Games in one place: Speed Roads, a two-player arcade in 3D, a shooter, and Prachový archiv — a western to explore and a turn-based strategy.
Learn to code
Python, C and C++: 12 practical lessons, then Mines and Snake. Write your own code and run local tests.
Hacking Simulator
Interactive security exercises with invented targets. Commands are game actions and do not run real network attacks.
Games
When you're tired of typing, play
The games are part of the app. They run in the browser, on a computer or a phone.
Red Mesa
An open-world western: ride a horse, arrest outlaws with a lasso, hunt game, rob a train. Your progress is saved.
Play
MHD Simulator
Drive a tram, bus or trolleybus through a big city, collect passengers and race rivals, online too.
PlayPrůsmyky
A strategy game on a map: lead an expedition to the Tarn Archive, against the computer or with friends by link.
PlayDouTok AI
The right pace for your work.
Choose how much room your task needs. These are DouTok routing profiles; available providers and limits depend on configuration and your plan.
01
Ares
Rewrite a paragraph or answer a quick question. Shorter output with a smaller compute budget.
02
Prisma
Write, plan and work with information. An everyday profile that looks up sources when needed.
03
Atlas
Explore a difficult problem or design code. More room for reasoning, output and sources.
Sköll
A switch for concise Ares answers when you want to get straight to the point.
Mimir
OCR, objects and images on your device. Generation is experimental and requires a supported GPU and Starter or higher. Ares Offline also offers lightweight local answers.
Open MimirPrepare to work without a connection
Your models. One place.
Find Ares and Mimir, download status and on-device setup in the offline model center. Download a model over the internet once; the app reuses complete saved files.
Ares Offline and Mimir generation require Starter or higher. Renew access online every 7 days. Image generation requires a supported GPU and enough memory; availability varies by device.
