$12,000 in free advertising credits across AI platforms, compiled into a single open-source markdown file. That's what darwin-studios published to GitHub this week, aggregating trial credits and promotional offers from AI advertising tools into one reference document.
The repository, named "dmos," covers credits spanning multiple platforms - AI-powered ad creation tools, audience targeting products, and campaign optimization services. The credits are a mix of new customer offers, promotional codes, and partner deals that typically sit buried across individual product landing pages.
For freelancers and small agencies running paid social or search campaigns, this kind of aggregation has real practical value. Hunting down trial offers platform by platform wastes time that most solo practitioners don't have. Having them in one file changes the calculus on which tools are worth trialing before committing budget.
The obvious caveat: credit offers expire, carry usage restrictions, and some require a credit card to unlock. A markdown file on GitHub won't update automatically when offers change, so the value of any specific entry will degrade over time. The file is most useful right now, at publication, and considerably less so three months from now.
For anyone running AI advertising experiments on a constrained budget, checking the file before paying for a new tool trial is a reasonable two-minute investment. The file is public and requires no account to view.
