# Use Local Files for Post Context

## Action

Command Claude to read a specific local screenshot or file to extract data for a post.

## How To Execute

1. Take a screenshot of relevant information (e.g., analytics dashboard, a book passage, an email).
2. Save it locally with a descriptive filename (e.g., `receipts.jpeg`).
3. In [[entity-claude-co-work|Claude Co-Work]], invoke your [[concept-claude-skills-d4|Skill]] (e.g., `/write-content`).
4. Tell Claude explicitly to reference the file by name and folder, e.g.:

   > *"Write a post about the receipts.jpeg image in my Downloads folder."*

Claude will locate the file, OCR/analyze its contents, extract the relevant data points, and weave them into a post in your brand voice.

## Underlying Capability

See [[claim-local-file-context|Claude can interpret local screenshots]]. The demo in the source shows extraction of *9.2M views* and *55,917 net followers* from a Facebook Insights screenshot.

## Caveats

- Requires [[prereq-claude-cowork-access|Access to Claude Co-Work or Claude Desktop]] — web Claude cannot do this.
- OCR is high-but-imperfect — verify numerical claims before publishing.

## Outcome

Accurate, data-driven content generated **without manual data entry**.
