🐦Arguably rotki's biggest strength is it creates a local database of all your financial history. Crypto and otherwise. You can analyze it through our awesome UI/frontend without leaking any privacy. And from next release you can ask LLMs to do whatever analysis you want on it!

Another key use case for @rotkiapp: enriched metadata for @monerium and @gnosispay. Rotki is my single source of truth, my crypto data layer. Then on top I use AI to query. Incredibly helpful for portfolio planning and month-end closing with my onchain business.

My rotki (running next version -- not production yet) already understands and uses GNS (the .gwei namespace). Pretty refreshing to have a tool that works with an ownerless and non-extractive name service in Ethereum. Should support more. PRs welcome 🙏 Use @rotkiapp 🐦
