TravelTalk - top phrases for travelers - hlavní vizuál projektu

TravelTalk - top phrases for travelers

Because I travel a lot around the world and sometimes stay in a given place for a month, sometimes two or three, I don’t need to learn the language of the country in a way that would let me speak it fluently. I need polite phrases more. In most cases there are about 4–5 of them that keep repeating — greeting, thanking, saying goodbye. For example, I have never once in my life asked in a country where the train station is or what time it is. Those are examples of phrases that seem important, but in reality are not. So what phrases are important?

FakturHuko - an alternative to Fakturoid - hlavní vizuál projektu

FakturHuko - an alternative to Fakturoid

An invoicing system for freelancers. A system I built after Fakturoid told me they would raise my subscription to triple the price. I love Fakturoid, but I didn’t want to pay that much. So now I pay nothing, and my solution does what Fakturoid did for me, plus a few extra things. Easy invoice creation, invoice management, client lookup using only company ID, recurring invoices.

AIFred - hub of my AI projects - hlavní vizuál projektu

AIFred - hub of my AI projects

I felt the need to create a hub for the projects I build with AI. And also a place to store ideas I want to work on later. Traditionally, WordPress would be used for this, but I wanted to create a CMS with AI as well so I could see what the pitfalls are. It’s a tough nut to crack, I can tell you that.

Crypto and Stocks - Portfolio - hlavní vizuál projektu

Crypto and Stocks - Portfolio

I bought various cryptos on different platforms, and sometimes even the same cryptos. Tracking their value and where they were held was complicated, so I created a tool that lets me keep an eye on it without forcing me to do anything too complicated. Recently, I also added a stock portfolio with charts, tips on current promotions, and more. It keeps growing.

Website Look Configurator - hlavní vizuál projektu

Website Look Configurator

When vibe coding, if you let AI too much freedom in choosing the design, all websites end up looking the same. I decided to dive a bit deeper into different graphic and UI styles and, at the same time, build a small app that lets you combine various styles and choose colors, typography... In just a few clicks, a person could select roughly the style that feels closest to them. This generates a link that gets sent to my email, and thanks to it the app outputs a prompt for AI with the specification of the chosen style.

Alfons Mucha - His Works and Detailed Exploration - hlavní vizuál projektu

Alfons Mucha - His Works and Detailed Exploration

I’ve always been drawn to art, but I don’t understand it very well. At the same time, I really enjoy the website https://artvee.com/, where there is a lot to discover about all kinds of painters and artists, mostly from history. When I was browsing Alfons Mucha’s images, I felt the urge to dive deeper into those works, and that’s how this project came to be.

Word to HTML - hlavní vizuál projektu

Word to HTML

I often receive materials in Word. If you use CTRL+C / V, for example into the Shoptet system, it gets copied with a lot of Word clutter. So I made a small app that turns Word into proper HTML code and extracts all images from Word so I can insert them into the article.

Updates

All updates
  • FakturHuko - redesign deployed

    We still need to fine-tune a few screens, color contrasts, and minor issues, but nothing that would prevent the app from being used comfortably. I think it looks great - https://fakturhuko.aifred.cz/

  • Anthropic Introduces the New Opus 8 Model

    This model currently seems to be the most intelligent, ideal for chat. For coding, ChatGPT 5.5 still seems better. One interesting point worth mentioning is that, according to the table in the article about the release of Opus 8 - https://www.anthropic.com/news/claude-opus-4-8 - it is also listed as the best for finance, but there is a note below the article saying that there is actually Financial Agent v2 from Google Gemini, which is much better. Much better. I recommend reading the footnotes ;-)

  • The FakturHuko redesign looks great

    When vibe coding, standard models usually suggest a fairly generic web app design, and that’s how the FakturHuko project started too. With Claude Design, however, the visual style of apps looks much more polished and the results are highly professional, almost in the style of “Graphic designers won’t have anything to eat.” But I’m not worried about designers; they’re artists, and they’ve always had it tough. The new look of FakturHuko is almost ready, and it will definitely be deployed next week. I’m already looking forward to working in the new outfit and issuing invoices there.

  • Claude AI Pro - paid version

    I couldn’t resist and wanted to find out what Claude Design is like, a feature available only in the paid version of Claude that lets you design sophisticated websites and app layouts. For now, I’m trying it out on websites for my profile on Reedsy.com, a platform for book writers, and using Claude Design to create a portfolio of book-themed websites. My first impressions are... that it’s slow and burns through tokens pretty quickly. It’s slow even when it comes to the actual coding. But overall, what the paid version of Claude offers seems interesting to me. I’m surprised, and it definitely deserves a full blog post later.

  • Elementor has released an easy accessibility checker

    The European Union requires certain types of websites to be accessible to people with disabilities. There are already plenty of tools for checking this, and Elementor’s one seems very user-friendly to me. Try it yourself to see whether your website is accessible: https://elementor.com/tools/ally-accessibility-checker/scanner

  • Connecting FakturHuko with FIO Bank

    Checking whether an issued invoice had been paid by receiving the payment in the bank seemed like a tougher nut to crack. I wanted this feature in FakturHuko because I liked it in Fakturoid. When a payment arrived in the account, the invoice status in the system changed to paid right away. In the end, it took only half an hour and it was done. FakturHuko can now match invoice status with received payments. And I also get an email notification when a payment arrives. Great.

LinkedIn, but for potential skills

Over the course of a career, a person gathers a lot of experience, mainly through the work they do for a living. But that does not always go hand in hand with what they would actually enjoy doing. For example, I enjoy photography, flying drones, and making videos, but I do not have enough experience for it to become my job — for someone to pay me for it. I would like a place where I could present what I can do, and especially what I would like to do if I could devote more time to it.

Custom Tool for Checking Website Accessibility

At the moment, accessibility is required only for certain types of websites, but overall the trend is moving toward websites being accessible in general. That makes sense. It also makes sense to have a tool for this that will evolve gradually as accessibility requirements evolve.

Website audit from the perspective of AI discoverability and SEO

SEO has been dead for quite some time; now the trend is AIO — optimization for AI. It’s important to know whether a website is ready for AI bots and whether it has the potential to be cited by AI in the links it lists as its sources.

How and where to launch a website built with AI

When you finish a website or app, the practical question comes up: where should you host it so it runs online? For smaller projects, three services often make sense today: Netlify, Vercel, and Railway. Simply put: Netlify and Vercel are best mainly for websites and frontend projects, while Railway is a better fit for applications that also have a backend or database.

Which technologies to choose when building an online project with AI

When you use AI to create a new web project, it’s important to choose the right technologies and to tell the AI which ones you want to use for your project. If you don’t, AI may choose a technology that isn’t ideal for your project. For example, if you want a custom cooking blog and AI builds it with React, your 100 articles about eggplant and carrots may never appear in Google search results. Here is a basic overview of suitable technologies for different types of projects.

Is it worth paying for Claude AI because of Claude Design?

A few days ago, I decided to create an account on Reedsy.com, a great tool for book writers. On this platform, they can not only write, but also choose the right professional to handle marketing, design, a new website, and more. I’m very interested in this whole field because I’d like to write a book myself. I’ve been dreaming about it for several years. So I wanted to be part of it, at least for now as someone helping those who have already written something.
