Use cases

What you can do with Core.

Examples of work in Core. Each one unfolds over time and keeps its sources, assumptions, alternatives, and decisions in one continuing workstream.

Why a workstream, not a chat

The work continues, and it holds up.

Persistent

Work continues across sessions instead of resetting.

Sourced

Sources stay attached and traceable.

Explicit

Assumptions and alternatives stay visible.

Reviewable

Python where useful, review before it counts, full history.

Individual

Long-running work that remembers why it exists.

Across months

Research a major decision

Maintain sources, assumptions, alternatives, calculations, open questions, and decisions across a relocation, major purchase, career change, or education decision.

Across a long project

Write a book

Preserve research, sources, characters, themes, editorial decisions, unresolved questions, and drafts in one workstream.

With real numbers

Manage a renovation

Track bids, documents, budget, decisions, change orders, open questions, and family input. Use Python where quantitative analysis helps.

Families and trusted groups

Shared work with boundaries that hold.

In their own words

Preserve family history

Combine interviews, photographs, records, dates, and memories, including conflicting recollections, without flattening every contribution into one fact.

Across the family

Coordinate elder care

Manage responsibilities, schedules, documents, questions, and decisions while preserving individual and shared boundaries.

Together

Plan shared work

Travel, estate organization, renovation, or a community project, with a clear record of who decided what.

Private individual understanding does not automatically become group understanding. Group understanding does not automatically become public.

Small teams

Everyone working from the same assumptions.

One workstream

Prepare for fundraising

Bring together founders, finance, model analysis, Python forecasts, source data, assumptions, and reviewer input.

With provenance

Run client research

Preserve client context, sources, assumptions, analysis, deliverables, handoffs, and review history.

With decision history

Build a product

Maintain product decisions, research, code work, user feedback, open questions, technical analysis, and decision history.

A workstream brings together people, models, Python workers, APIs, Skills, and reviewers, and keeps track of who did what. Worker output is draft and pending review.
