InvoiceProof

What it does

InvoiceProof is invoice insurance for freelancers, contractors and small business owners. Every invoice gets a tamper-evident audit trail, IP logging, e-signatures, and a Chain of Custody document you can hand a small claims court, not just a "read receipt." When a client disputes, you have cryptographic proof they saw and agreed.

Send invoices with built-in read receipts, IP logging, and a tamper-evident audit trail. When a client claims they never got your invoice, you have the record to prove they did.

Right now, any client can say they never got your invoice and there is nothing you can do about it. InvoiceProof changes that. Create your invoice, import line items from a CSV, or pull clients and invoices directly from QuickBooks. Send it in one click. Your client gets a link. No account, no app, nothing to install. The moment your client opens the email or views the invoice, we record it. IP address and timestamp on every action, locked into a tamper-evident log they cannot dispute. One click generates a complete Chain of Custody document showing every event in sequence. Attach it to a demand letter, send it to a collections agency, or share it with an attorney. Your record is already…from invoiceproof.io

  I built a tiny LLM to demystify how language models work▲915

  Built a ~9M param LLM from scratch to understand how they actually work. Vanilla transformer, 60K synthetic conversations, ~130 lines of PyTorch. Trains in 5 min on a free Colab T4. The fish thinks the meaning of life is food. Fork it and swap the personality for your own character.

  I built a frontpage for personal blogs▲783

  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.
