It works from ChatGPT or Claude through an MCP connector.

Oodrive Sign

Oodrive Sign is an API-first electronic signature solution, designed and hosted in France, for organizations that cannot compromise on legal validity or data sovereignty. It supports all three signature levels defined by the European eIDAS regulation — simple, advanced and qualified (QES) — so each document is signed at the level its risk actually requires. The REST API embeds electronic signature directly into business applications and software products. Developers get SDKs for JavaScript, Python, PHP, Java and .NET, real-time webhooks, a Salesforce connector and a free sandbox to test every endpoint before going live. Signing journeys are fully brandable, so signers stay within the customer’s own experience, and workflows can be triggered by business events. For teams without an integration project, the same signature engine is available through a ready-to-use web platform, accessible from any device with no technical setup. Users can send a document in one click, run a full signing flow with specific requirements, or have several related documents signed with a single consent. Reusable templates, parallel and sequential signing, cascading approvals, multi-approver workflows and a centralized electronic signature book support teams that handle documents in volume. Every transaction produces a timestamped audit trail with verifiable certificates — evidence admissible before European courts. Documents can be signed remotely, face to face or offline, and identity verification options include European schemes such as itsme. Compliance is built in rather than added on. Oodrive Sign is hosted in France on SecNumCloud-qualified infrastructure, is ISO 27001 certified and HDS certified for health data, and complies with GDPR and RGAA accessibility standards. Evidential archiving is available for documents that must remain provable for years. Oodrive Sign is used by software vendors, public sector bodies, banks, insurers, notaries, legal departments, real estate firms, HR and sales teams. Common use cases include employment contracts, insurance subscriptions, loan agreements, SEPA mandates, public procurement documents, notarial deeds, lease agreements and sales quotes. Two plans are offered: Sign API, for organizations embedding signature into their own products or applications, with tiered per-transaction pricing; and Sign Liberty, the web platform with unlimited users and volume-based pricing. Oodrive, the company behind Oodrive Sign, is a European provider of trusted digital solutions for sensitive data.

PactaHQ

PactaHQ is an electronic signature platform that streamlines document signing workflows while embedding proof of authenticity directly into completed PDFs. The platform allows proof to travel with the document rather than storing evidence in a separate database. Users upload PDFs, place signature and input fields, configure recipient details and signing order, and send private signing links. Signers verify their identity via one-time email codes without creating accounts. Signed documents are cryptographically sealed with Ed25519 digital signatures for tamper-evident verification. Security features include hash-chained audit trails and SHA-256 hashed signing links to ensure data integrity and prevent unauthorized access. The platform supports seven field types, sequential and parallel signing orders, reusable templates, automatic reminders, and expiration dates. All plans offer unlimited documents, signers, audit trails, and sealed PDFs with ESIGN Act and UETA compliance.

PaperOffice AI

PaperOffice AI is an AI document management system (AI-DMS) for teams that handle invoices, contracts and correspondence. Documents arrive by upload, email, scanner, mobile web app or connected storage, are read with OCR in more than 120 languages and turned into structured data: document type, supplier, amounts, dates, IBAN and line items. Built-in checks flag duplicates, changed bank details and missing fields. Workflows route documents to people for review and approval (human in the loop), and AI agents answer questions about your archive. PaperOffice AI is API-first: more than 300 API and MCP functions connect it to your systems, and the MCP server brings your documents into Claude and ChatGPT. Ready-made integrations include n8n, Make, Zapier, Odoo, Zendesk, Pipedrive, monday.com, Airtable and more. All processing runs in our own EU data center. The app is available in 21 languages.
