SignDocs Brasil

SignDocs Brasil is a document-signing service for electronic and digital signatures with legal validity. It presents itself as more than a signer, describing the product as a document manager for signatures and document handling.

The service supports PDF upload, automatic file validation, document classification, and the definition of how many people will sign. For each participant, it allows email, name, and signature type to be configured, with either an electronic signature or a digital signature with certificate. It also sends signers automatic email invitations with a secure link, generates the final document after all signatures are collected, and includes a certificate of authenticity together with a complete audit trail. Other listed functions include searches by CPF/CNPJ, signatories, and tags, public verification of signed documents, end-to-end encryption, and immutable logging with date, time, and IP for each participant. Batch signing is available on the Avançado and Enterprise plans.

SignDocs Brasil also exposes signing through multiple delivery channels. The page names a web app, public API, and Telegram bot, and says the mobile app is available in the Play Store and App Store. For developers, it offers Assinatura Expressa through a single API call, with nine authentication profiles, three integration modes, SDKs in six languages, and support through a Model Context Protocol server; Claude is listed as working through that MCP server on the web, in Code, Desktop, and via API. The site also lists integrations with n8n, Lovable, WordPress, and Nextcloud.

Pricing includes a free plan with 5 documents per month for one user, 2FA with TOTP, and ICP-Brasil, as well as paid plans named Iniciante, Avançado, and Enterprise. The pricing table also mentions annual and monthly options, subusers on paid tiers, team management on the Iniciante plan, CSV/XLSX/TXT import and batch signing on Avançado, and REST API, Assinatura Expressa, SDKs, custom subusers, and dedicated support on Enterprise.
