Distinct products. Operations with context.

Organize your work across three families. Use each product for its purpose and combine your own references where supported, with reviewable results and access scoped to your account.

Product-specific access and data boundaries
Product-specific access and data boundaries

Family 1

Fiscal and invoices

Issue CFDI 4.0 and validate invoices in batches. Each product keeps its specific fiscal scope.

  • Electronic invoicing
  • Invoice validation

Family 2

Investigation and exposure

Investigate open sources with OSINT tools. Bounded results, not universal proof of security.

  • OSINT Suite

Family 3

Voice and applied intelligence

Turn audio and video into text, with result exports.

  • Speech to text

From source to a reviewed decision

A common language of sources, evidence and review. Each step stays within the selected product's scope.

  1. 1. Choose your sources

    Import supported formats, such as CFDI invoices or audio files.

  2. 2. Apply the workflow

    Run bounded validations, searches or transcriptions. Product limits, quotas and provider conditions remain in force.

  3. 3. Review with context

    Inspect provenance and unknown states. Human review remains where the product requires it.

  4. 4. Keep the evidence

    Export in supported formats and consult history within its retention period.

Sharing a family does not grant access to other products or activate automatic integrations. Connections use explicit, authorized references.
