Projects
I build web-based tools and SaaS products that solve real problems — from everyday text conversion to intelligent document management. Everything here is live and free to try.
Paperarchive
Smart document management that understands your work and life.
Paperarchive is my flagship product — a document management system that automatically categorizes, tags, and connects your documents using AI. Upload a scan, a photo, or forward an email, and Paperarchive makes it instantly searchable and intelligently linked to your other documents. Built for freelancers and families who are tired of folder chaos.
Made and hosted in Germany. Privacy-first by design.
MarkdownToText
Convert Markdown to plain text, rich text, or HTML — instantly.
If you've ever copied output from ChatGPT or another AI tool and needed clean, unformatted text, this is for you. Paste your Markdown, pick your output format, and you're done. No sign-up, no ads, no nonsense.
TextToMarkdown
Turn plain text into structured Markdown with smart detection.
The companion to MarkdownToText. Paste unformatted text and the tool automatically detects headings, lists, links, and emphasis to produce clean Markdown. Great for converting emails, meeting notes, or legacy documents into a format that works everywhere.
FileSizeConverter
Convert between file size units — bytes, KB, MB, GB and beyond.
A simple, fast calculator for converting between file size units. Useful when you're comparing storage plans, setting upload limits, or just trying to figure out how many megabytes 1.5 gigabytes actually is.
ENEXExtract
Extract attachments from Evernote export files.
Leaving Evernote? ENEXExtract lets you upload your .enex export files and pull out all embedded attachments — images, PDFs, documents — so you don't lose anything in the migration. Built with Nuxt 3, available in English and German.
All tools are built and maintained by me. Have an idea, found a bug, or want to collaborate? Get in touch.
