Chase – automated invoice follow-up emails for freelancers
Stripe-integrated invoice follow-ups, but Freshbooks and Wave already have this built-in.

Automated PubMed summaries emailed weekly for eight specific research topics.

I was trying to understand what was happening, but I found that scientific papers came with jargon and the dense PubMed UI.
I'd use ChatGPT to simplify studies, and eventually built OpenScience.ink as a more structured version of this.
At the moment, it scans PubMed every morning for new papers across 8 topics: • Long Covid • Circadian Biology • Psychedelic Science • CRISPR • GLP-1s • Gut-Brain Axis • Longevity & Aging • mRNA Technology
And every week (on Mondays), it sends a newsletter in each topic with the most relevant studies from the past week.
The idea is to make it easier to keep up with new research in plain English.
