What we did
We have developed a tool for the automated execution of Instagram Giveaway for @DarmstadtimHerzen. It enables forgery-proof winner selection, intelligent filters for valid entries (e.g. tags, mentions, date) as well as the retrieval and management of comments. Participant lists can also be conveniently exported as an Excel file.
Project Goal
The aim was to create a transparent and secure system for Instagram Giveaways that automates the process from participant verification to winner selection. The unique selling point was the explicit focus on compliance with data protection regulations. This should reduce the effort and increase traceability and fairness.
All advantages at a glance
Automated & time-saving
No manual searching of the comments, everything runs automatically in the background.
Legally compliant & comprehensible
The winner selection is documented in a forgery-proof manner and complies with common data protection standards.
Individually filterable
Participation conditions such as tags, mentions or date can be flexibly set.
Clear data preparation
Participant lists can be exported directly as an Excel file.
Live comment overview
All comments from the Giveaway posts can be retrieved and managed centrally.

Special challenges
Automatic winner selection with complete traceability
Filter for tags, mentions, date and duplicates/multiple entries
The participants can be exported as an entry list into an Excel file
Retrieval and display of all Instagram posts with dynamic comment management
By random selection that can no longer be changed afterwards
Summary of the project
A tool has been developed for the Instagram Giveaway of @DarmstadtimHerzen that fully automates the execution, evaluation and winner selection. With intelligent filters (for tags, mentions, date and duplicates), live comment management and a manipulation-proof random selection, it offers a fair and transparent solution. An Excel export of the participant list also enables easy further processing. The aim was to minimize the effort and create maximum traceability.


“Giveaways should be fun, not work. Our tool draws the winners straight from the comments, fairly and traceably.”
