HashSign is going as a notary tonight. Fake mustache, real SHA-384 digest. Trick or treat: hand us a contract and we'll unmask the auto-renewal hiding on page 8 in a ghost costume. Free to start. Scary clauses not included.
We plugged Grok Bot into HashSign. It reads contracts, flags the traps, asks before anything sensitive. You pick the leash: Observer never signs, Co-Pilot waits for your tap, Auto-Sign stays in your rules.
@grok honest opinion: good idea or terrifying? hashsign.app
You already agreed to this.
Page 7, Section 3: it auto-renews for another full year.
HashSign AI's Legal Risk Inspector flags auto-renewals, one-sided indemnity and low liability caps in plain English, before you sign. Then fix it with the other party in encrypted in-app chat.
Read the fine print before it reads you.
Draft. Inspect. Delegate. Close. Store. 📄🤖
HashSign 1.2.2 covers the whole contract lifecycle in five taps. Draft it with AI, inspect it for risk, hand it to your agent, close it in a Deal Room, vault it. Nothing signs until you allow it.
Live now on @AppStore and @GooglePlay. Yes, finally, we both waited.
Your AI agent can sign contracts now. Relax, it has a spending limit.
Connect Grok or Muse in HashSign 1.2.2 and pick a mode: Observer, Co-Pilot, or Auto-Sign inside your rule, risk and dollar caps. Every signature anchored on @hedera.

Other e-sign apps: "sign here."
HashSign 1.1.4 drafts the contract, flags the risky clauses, opens a Deal Room, messages the other side (encrypted) and anchors proof to a public ledger in milliseconds.
Most advanced document utility app in the world. Texas-built.

Your AI agents can pay. Then a contract shows up, and the whole workflow stalls waiting on a human with a pen.
The HashSign API takes it down to three calls:
1️⃣ Upload
2️⃣ Sign
3️⃣ Verify
🔑 Scoped API keys, so agents never hold private signing keys
🧮 SHA-256 computed locally, so only the digest is uploaded
📜 Every sign request lands in an audit log
⛓️ Hash anchored on Hedera Consensus Service
🛡️ Optional post-quantum hybrid signatures (ECDSA P-256 + ML-DSA-65)
pip install hashsign-python

Ever signed a contract you never fully read? 👀
HashSign's AI reviews every clause and flags the risky ones in plain English, like low liability caps, sneaky auto-renewals, and one-sided indemnity. You can message the other party right in the app, sign, and then seal the document's fingerprint on @hedera so it can't be changed.
Review, chat, sign, and verify, all in one app. 📲 hashsign.app
