Chief Assistant · Integrated shipboard workflow

Record once.
Spend less time retyping.

Enter the task, actual hours and crew. Use the confirmed record for daily reports, work/rest hours and supported document templates.

01 · Record the activity

Record the work activity, start and finish times, and crew members who actually participated.

02 · Update linked records

Use confirmed participation in Jobs & Safety, Unified Timeline and linked MLC records. Planned tasks and actual work remain separate.

03 · Prepare operational documents

Populate supported company document templates from the available records. Responsible officers complete the required review, approval and signature steps.

04 · Control amendments

Approved actual-work records are locked. Authorised amendments retain the reason, previous entries, user identity, timestamp and revision history. Reposting the same task updates its existing participation record without creating a duplicate.

Document preparation depends on the configured template and supported field mappings. Amendments to work-hour records do not automatically alter signed documents, permits to work or recorded approvals.

Roadmap · In development

Next: local AI support
for the core products.

AI Mission Control and maritime assistant workflows are in development. The intended local mode runs on customer-controlled infrastructure without external AI requests; any optional cloud connection is a separate configuration. Officers retain the final decision.

Maritime AI Mission Control concept: IMO references, Company SMS, vessel manuals and crew documents with source-linked answers
