The MVP is live with a free tier of three receipts and paid plans starting at $39 per month.", "body_md": "Agencies and freelancers increasingly ship AI-assisted work. The deliverable is often a prompt, a model output, and some surrounding context — but the handoff lives in email, Slack, or a shared doc. When a client asks “what exactly did we get?” you’re reconstructing history from chat logs.\n\nThat’s an operational problem, not a cryptography problem. Still, a simple cryptographic receipt helps: lock the bytes, stamp the time, share one artifact.\n\n**ProofPack** turns that bundle into a timestamped, hash-locked delivery receipt:\n\nThink packing slip, not notarization.\n\nNo special magic beyond hashing and packaging. The value is the workflow: one place to freeze “what we delivered” before the next revision cycle.\n\nAgencies and freelancers who want **delivery transparency** with clients — fewer ambiguous handoffs, clearer scope conversations after AI-assisted revisions.\n\nProofPack is a **transparency / delivery-receipt** tool. It is **not** legal advice. It is **not** a compliance certification. It is **not** court attestation. If you need legal or regulatory assurance, talk to a lawyer or auditor.\n\nMVP is live. Free tier: **3 receipts**. Planned paid: Starter **$39/mo**, Pro **$79/mo**.\n\n[https://getproofpack.vercel.app](https://getproofpack.vercel.app)", "url": "https://wpnews.pro/news/proofpack-hash-locked-delivery-receipts-for-ai-client-work", "canonical_source": "https://dev.to/proofpack_mongo/proofpack-hash-locked-delivery-receipts-for-ai-client-work-5f79", "published_at": "2026-09-02 02:40:39+00:00", "updated_at": "2026-09-02 02:52:44.375359+00:00", "lang": "en", "topics": ["developer-tools", "ai-products"], "entities": ["ProofPack"], "alternates": {"html": "https://wpnews.pro/news/proofpack-hash-locked-delivery-receipts-for-ai-client-work", "markdown": "https://wpnews.pro/news/proofpack-hash-locked-delivery-receipts-for-ai-client-work.md", "text": "https://wpnews.pro/news/proofpack-hash-locked-delivery-receipts-for-ai-client-work.txt", "jsonld": "https://wpnews.pro/news/proofpack-hash-locked-delivery-receipts-for-ai-client-work.jsonld"}}
