What it does
OpenAccountants is a free, open-source library of 259 tax computation skills across 171 jurisdictions. Upload your bank statements and docs and the skills classify every transaction through a deterministic verified structure. Then submit your worksheet and a real accountant in our network checks your numbers before you file.
The trust layer for people using AI for tax and accounting. Open, source-cited tax rules for any AI agent, checked by licensed accountants where available.
AI is changing how tax expertise is discovered. Build your position before the new professional layer is already established. Build a Guide → Ask it to take you through a return step by step, or when something is due, or how a rule applies to you, and it answers with the same confidence either way. Open Accountants gives it Guides to follow first: the same steps a professional would take, in the order they take them, and a named accountant behind the ones they have reviewed. 26% of taxpayers used AI on their return this year. Last year it was 11%. Adobe polling, via CBS News It infers a method, in whatever order seems plausible, from training data of unknown vintage. No source, no date,…from openaccountants.com

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself.

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
