RelayFlow

RelayFlow is a platform for building automated content workflows around Telegram and RSS.

The goal is simple: instead of manually copying, editing and reposting content, you create a workflow once and let it run automatically.

What RelayFlow can do

  • Monitor Telegram channels and RSS feeds
  • Aggregate content from multiple sources
  • Filter posts using your own rules
  • Rewrite content with simple AI prompts
  • Translate posts into other languages
  • Summarize long articles
  • Automatically publish processed content

No coding is required. Most transformations can be described in plain English.

For example:

โ€œRewrite this post in a more casual tone.โ€

or

โ€œTranslate to Spanish and keep all links.โ€

or

โ€œOnly publish posts about AI.โ€

Typical use cases

  • Run a Telegram news channel from multiple sources
  • Aggregate industry news into a single feed
  • Republish content in different languages
  • Remove duplicates and unwanted posts
  • Automatically adapt content to your own writing style
  • Build AI-powered content pipelines without writing scripts

Current status

RelayFlow is currently in Public Beta.

The core functionality is already working, but there are still rough edges, missing features and probably a few bugs. The focus right now is on improving the product based on real user feedback rather than trying to make everything perfect before launch.

If something feels confusing, missing or broken, please let me know. Every piece of feedback helps prioritize what gets built next.

Iโ€™m especially interested in hearing:

  • Which workflows you wanted to build
  • Which features are missing
  • Where the UI is confusing
  • Anything that simply doesnโ€™t work as expected

Thanks for taking the time to try RelayFlow. ๐Ÿš€

The best diff GUI tool I've been able to find for OSX is DiffMerge (https://sourcegear.com/diffmerge/) on the App Store, and I'd like to have a tree view for folder comparisons. - Source: Hacker News / over 4 years ago
