closeit.fast: Lightweight E-Signature Tool with Audit Trails and Tamper-Evident Hashing

LinkTool

closeit.fast is a streamlined browser-based electronic signature service. Users can upload PDFs or images, place signature and text fields, and route documents to signers without requiring them to create an account.

Key points

  1. Accepts PDF, PNG, and JPG files up to 20 MB, using relative page coordinates to ensure consistent field placement across screen sizes.
  2. Signers access documents via single-use links without account registration or app installations, signing by drawing or typing on mobile or desktop.
  3. Alined with ESIGN Act and UETA requirements, including recorded explicit consent before signing.
  4. Every envelope generates an audit trail capturing UTC timestamps, IP addresses, and user-agent data, finished with an appended completion certificate and SHA-256 hash.
  5. Document storage uses AES-256-GCM encryption with cryptographic keys held separately from stored files.
  6. Pricing model includes a free tier offering one envelope per month, and an unlimited plan priced at $12 per month or $6 per month when billed annually.

Why it matters

Traditional e-signature providers often lock essential features behind costly enterprise tiers or require signers to register accounts. closeit.fast offers an accessible, pay-as-you-go or low-cost flat alternative with verifiable cryptographic integrity.

Analysis

The platform focuses strictly on execution speed and verifiable proof. Storing field coordinates relative to the underlying page avoids layout shifts across varying viewports. Post-signing, entries are flattened, a completion certificate is attached, and the file digest is recorded, allowing external verification of document integrity via SHA-256. While structured around the US ESIGN Act and UETA framework for basic e-signatures, users subject to stricter European eIDAS regulations will note it provides simple rather than advanced or qualified electronic signatures.
