# Re-running Enrichment

> Update your AI prompts and re-run enrichment to improve attribute values across your catalog.

# Re-running Enrichment

After you've reviewed your AI-generated content, you'll often want to re-run enrichment to improve results. Maybe your product descriptions need more detail, or you want to tighten up your category assignments. This article covers when and how to re-run enrichment safely.

## When to Re-run Enrichment

Re-run enrichment when you've made any of these changes:

* **Updated attribute prompts** — You refined your prompt for product descriptions or added brand guidelines.
* **Added new acceptable values** — You expanded the list of valid categories or size options.
* **Added more sources** — You imported additional product data (images, specs, reviews) that the AI should use.
* **Fixed attribute configuration issues** — You corrected a field type, enabled AI on an attribute, or changed the product data context.

You might also re-run enrichment if you're not happy with the quality of previous output and want to test a new approach.

## How to Re-run: Your Two Options

When you re-run enrichment, you have two very different modes:

### Generate All Attributes

Select your products, then choose **Generate → Generate All Attributes** (or press ⌘↵).

This mode **overwrites every AI-configured attribute**, whether it already has a value or not. Use this when you've made significant prompt updates or configuration changes and want the AI to start fresh.

**What happens:**

* Every attribute with "Use AI" enabled gets regenerated.
* Existing values are replaced, including any manual edits you made to those cells.
* Manually edited attributes (those with "Use AI" disabled) are left alone.

### Generate Empty Attributes Only

Select your products, then choose **Generate → Generate Empty Attributes Only**.

This mode **preserves any values that are already filled in** and only generates values for empty cells. Use this for incremental enrichment — filling gaps as you add new sources or attributes without touching what's already there.

**What happens:**

* Only empty cells get values from AI.
* Existing values (from previous AI runs or manual edits) stay exactly as they are.
* Manually edited attributes are never touched.

## Understanding What Changes and What Doesn't

The key difference is this:

| Scenario                         | Generate All                | Generate Empty Only     |
| -------------------------------- | --------------------------- | ----------------------- |
| Attribute is empty               | ✓ Generates value           | ✓ Generates value       |
| Attribute has AI-generated value | ✓ Overwrites with new value | ✗ Leaves existing value |
| Attribute has manual edit        | ✗ Overwrites (⚠️)           | ✗ Leaves existing value |
| Attribute has "Use AI" disabled  | ✗ Leaves value alone        | ✗ Leaves value alone    |

**Pro tip:** If you have manually edited some cells and don't want them overwritten, use "Generate Empty Only" — it respects your manual work.

## Testing Before You Scale

Never update a prompt and immediately re-run on your entire catalog. Test first:

1. **Pick a small batch** — Select 5–10 representative products.
2. **Run Generate All** — Apply your updated prompt to just these test products.
3. **Review the output** — Check if the new results are better than before.
4. **Compare side by side** — Look at before and after values. Did tone improve? Are keywords included?
5. **If satisfied, scale** — Select your full catalog and re-run with confidence.
6. **If not satisfied, iterate** — Refine your prompt again and test on the same 5–10 products.

## Re-running Specific Attributes Only

You can't target individual attributes through the Generate button — when you run Generate, all AI-enabled attributes are processed.

If you need to re-run just one attribute (say, descriptions), here's the workaround:

1. Go to **Workspace → Attributes**.
2. Find every other attribute with "Use AI" enabled.
3. Disable "Use AI" on each one temporarily.
4. Run **Generate All** — now only your target attribute will generate.
5. Review the output.
6. Go back to **Workspace → Attributes** and re-enable "Use AI" on the other attributes.

This takes a few extra steps, but it's the only way to isolate a single attribute.

## Common Issues and Fixes

**My values look exactly the same as before.**
Check that your prompt actually changed. Small tweaks (removing one word) might not create visible differences. Try a more substantial change (add a paragraph about target audience, change tone from "technical" to "friendly").

**I lost my manual edits.**
You used Generate All on attributes you'd manually edited. Switch to "Generate Empty Only" next time to preserve your work. If the damage is recent, you can undo with Ctrl+Z or Cmd+Z immediately.

**Some products didn't generate new values.**
Check if those products have required attributes that are still empty (e.g., a missing "Brand" field that your prompt depends on). The AI won't generate values if it doesn't have the inputs it needs. Fill in required fields first, then re-run.

**Re-run is taking too long.**
Large catalogs take time. If you're re-running your entire catalog at once, consider batching instead (see article 3.14). You can also close other browser tabs to free up resources.
