From fast remote support to a custom-developed business application: on this page you will find each of our services described in detail – with scope of work, process and all terms.
This page describes all eight Computer Heiler services in detail: scope of work, process and full terms. Billing is to the minute, with no minimum duration and no basic fee. For the three project services, a written estimate of the effort involved comes first instead of a list price.
Billing is to the minute, with no minimum duration and no hidden basic fees. For project services you receive a written estimate of the effort involved in advance. Frequently asked questions are answered in our FAQ on IT service and remote support; technical terms are explained in the glossary of IT and AI terms.
Remote assistance over an encrypted connection
Most software problems can be solved without anyone having to drive out to you. With remote support we connect to your computer after your express approval. You watch everything that happens on your own screen the whole time and can end the session at the push of a button at any moment. All that is needed is a working internet connection – remote support is available throughout Germany, not just in the area around Kaiserslautern.
Personal data, passwords and banking details are not accessed. After the session, the connection software is completely removed again. Further details are set out in our privacy policy.
We come to you – within a 50 km radius of Kaiserslautern
Some things can only be done on site: replacing a faulty hard drive, adding memory, cabling a network or rebuilding a computer that will not start at all any more. Then we come to you – at home, in the office or in the workshop.
Our service area covers a 50 km radius around Kaiserslautern, including Neustadt an der Weinstraße, Pirmasens, Zweibrücken, Landau in der Pfalz, Rockenhausen, Kusel, Homburg (Saar), Landstuhl, Ramstein-Miesenbach and Lauterecken.
Restoring lost data
When data has disappeared, every decision counts. We restore accidentally deleted files, formatted drives, faulty hard disks and damaged databases – for Windows, macOS, Linux as well as Android and iOS devices.
Every job begins with a preliminary analysis. In it we check the condition of the storage medium and assess what can realistically be recovered. Only then do you decide whether we continue. The chances of success depend on the type of damage and the condition of the medium – no reputable provider can give a guarantee.
Ongoing support instead of firefighting
For businesses that do not employ their own IT staff but still do not want to do without reliable support: we look after your systems continuously, instead of only turning up once something has already failed.
We define the scope and response times together and record them in writing. Maintenance contracts are available in limited numbers, because we want to genuinely look after every customer, not merely administer them.
Text, images and a sensible start with AI tools
Since 2023, large language models have fundamentally changed the way we work with technology. The difference between a disappointing and an astonishingly good result almost always lies in how the task is formulated – in the prompt.
We develop reusable prompts for ChatGPT, Claude, Bard, Bing or Llama for you, show you with your own tasks what the tools can do – and just as clearly where their limits lie. This also includes image generation with FLUX, Stable Diffusion, DALL-E and Midjourney.
Bespoke applications since the early 1990s
Not every business process can be sensibly mapped with standard software. Where industry solutions are too rigid, too expensive or simply too cumbersome, we develop an application that maps your process exactly – rather than the other way round, adapting your process to someone else’s software.
Custom software development has been part of our daily work since the early 1990s. In that time, programming languages, databases and user interfaces have changed fundamentally several times over – the questions behind them have stayed the same: what should the program really do, who works with it, and what happens to the data in ten years’ time?
We work in comprehensible milestones. After each stage you receive a working version, clear documentation and the opportunity to reset priorities. The source code and the rights of use for the solution created for you belong to you – you stay independent, including of us.
Editorial system with no online login – for blogs and news sections
Anyone wanting to maintain a blog or a news section normally installs a CMS on the web server. That puts a login screen on the internet, with user accounts, a database and usually a series of extensions as well – all software that has to be kept permanently up to date. This is precisely where the vast majority of attacks on websites begin: at the login screen, at outdated extensions, at stolen credentials.
Our offline CMS turns the principle around. The editorial application is installed locally at your premises and runs on your own computer – not on the server. You write your posts, format them, insert images and see the preview without anything having to be online. Only the finished post is published, over a transmission route set up specially for that purpose and deliberately tightly restricted, which serves this purpose alone.
Afterwards, no editorial software runs on the web server. There is no login screen, no user account and no database there that could be attacked. The published website stays static – fast, frugal to run and without the regular security updates that a classic CMS inevitably brings with it.
Your content remains entirely with you at all times, in a readable format on your own computer. Even later, when the website is one day rebuilt or moved.
Your own language model – with your data, on your premises
Public AI services are convenient, but they have two catches: your data leaves the company, and the model knows neither your terminology nor your internal processes. Both can be solved. Open language models – open source or freely available weights – can be run on your own hardware and retrained specifically for your use case.
We first assess soberly whether fine-tuning is the right lever at all. Often a clean knowledge connection to your existing documents is enough, and that is considerably cheaper. Only when it comes to a fixed writing style, recurring formats or specialist vocabulary is genuine retraining worthwhile – usually efficiently via LoRA/QLoRA rather than full training.
The result runs on a single GPU workstation or a small server at your premises. No request leaves your network, there are no running costs per request, and you are not dependent on any provider who might change prices, models or terms of use tomorrow.
A model that knows manuals, work instructions and project documents and points staff to the right place in seconds – instead of half an hour of searching the network drive.
Incoming e-mails and tickets are automatically classified by topic, urgency and responsibility and supplied with a draft reply that a human only has to approve.
Quotes, reports and product texts in your terminology and your tone of voice – including the industry-standard abbreviations that general models regularly fail on.
Invoices, delivery notes, forms or inspection reports become usable data records that go straight into your database or ERP system.
HR, client or patient data must not leave the building. A locally operated model makes AI analysis possible even where cloud services are ruled out.
The model is integrated into existing software via an interface – on request together with a custom-developed application.
The choice depends on the task, the language and the available hardware – not on fashion. Among those that have proved themselves are:
Licence terms differ considerably from model to model – not every freely available model is open source in the narrower sense or usable commercially without restriction. We check this before making a selection and record the result in writing.
Tell us about your problem – we will tell you honestly what makes sense and what does not. We usually get back to you within one working day.
info@computerheiler.euIn most cases remote support. A computer that has become slow is rarely a hardware defect, but the result of too many auto-start programs, a full system drive, outdated drivers or malicious software. All of that can be analysed and fixed remotely. Only if it turns out that components need replacing, such as switching from a classic hard drive to an SSD, does it become an on-site appointment.
The on-site service costs 70 euros per hour, billed to the minute. On top of that there is a one-off travel flat rate per appointment: 20 euros within the city of Kaiserslautern, 25 euros up to 25 kilometres away and 30 euros between 25 and 50 kilometres. A two-hour visit in Landstuhl therefore costs 140 euros plus 25 euros travel.
System analysis and clean-up, software installation and updates, setting up and checking data backups, virus and malware removal, configuring e-mail and browsers, as well as training and general computer questions. AI consulting and prompt engineering also run entirely remotely. Everything that requires physical presence, such as hardware replacement or network cabling, has to be done on site.
Because the scope, the technology used and the depth of support differ considerably from project to project. A small report over an existing database and the replacement of a legacy system that has grown over time, including data migration, have nothing in common. Instead of a list price there is therefore a non-binding initial consultation at the start, followed by a written estimate of the effort involved. The same applies to the offline CMS and to the fine-tuning of language models.
Every job begins with a preliminary analysis for a one-off 100 euros. The condition of the storage medium is examined and an estimate is made of what can realistically be recovered. This fee is non-refundable, but is credited against the total price if the recovery succeeds. Only after the preliminary analysis do you decide whether to commission the actual recovery at the hourly rate of 150 euros.
