Four ways to generate

From a topic

Enter a topic (e.g., “remote-team collaboration software”) and a count, then click Generate. The AI produces N testimonials with client name, role, company, text, and rating.

Topic: "SaaS project management tool for remote teams"
Count: 8
Tone: Professional, enthusiastic
Target audience: Small businesses with 10-50 employees

The more specific the topic, the more realistic the testimonials.

From a URL

Paste a URL. The plugin:

  1. Fetches the page (via UrlScraper class).
  2. Strips HTML and boilerplate, extracting up to 15,000 characters of main content.
  3. Sends the content to the AI with instructions to generate grounded testimonials.

Best for: turning an existing product page, landing page, or About page into testimonials that reference real features.

The scraper extracts visible text only — it does not execute JavaScript, so SPAs may not scrape well.

From a PDF or document

Upload a PDF, DOCX, or TXT. The plugin:

  1. Parses text from the document:
    • PDF — via smalot/pdfparser. Scanned/image-only PDFs fail.
    • DOCX — via PhpWord (transitive via LLPhant).
    • TXT — encoding detection and pass-through.
  2. Sends the extracted text to the AI.

File size limit: 5 MB.

Good sources: product briefs, marketing documents, feature lists, customer research summaries, company descriptions.

Category generation

Generate a category name and description from a short prompt. Useful when seeding a new site.

  1. In the category form, click Generate with AI.
  2. Enter a short hint (e.g., “reviews from SMB customers”).
  3. The AI returns a name and description — accept or re-roll.

Review and import

After generation, the testimonials appear in a preview table.

For each row:

  • Edit inline — click any field (name, role, company, text) to edit.
  • Rating stars — clickable 1–5 stars.
  • Regenerate name — rewrite just the client name from the testimonial text.
  • Regenerate content — rewrite just the testimonial text.
  • Suggest category — AI suggests the best-matching existing category.
  • Select / Deselect — checkbox to include or exclude.
  • Remove — drop from the batch.

Category assignment modes

Before importing, choose how to assign categories:

Mode Behavior
Specific Assign one category to all imported testimonials.
Auto-assign with AI For each testimonial, AI picks the best-matching category.
Individual per-testimonial Each row has its own category dropdown.

Import

Click Import Selected. Selected testimonials are saved to the database with:

  • status = draft (or chosen import status).
  • source = ai-generated.
  • language_code = from the Language setting in the generator.
  • translation_group = new UUID per row.

No testimonials are saved until you explicitly import them.

Multilingual generation

If Multilingual is active, the Target language field appears. The plugin generates in the specified language and sets language_code on the imported testimonials.

For translation of existing testimonials: the current release generates fresh testimonials; full AI translation of existing content is on the roadmap.

Hooks

Hook Type Description
plugixatestimonial_before_ai_generate action Before a generation request. Args: topic, provider, count.
plugixatestimonial_after_ai_generate action After a successful generation. Args: testimonials, topic, provider.
plugixatestimonial_ai_generated_testimonial filter Modify a single generated item.
plugixatestimonial_ai_generated_testimonials filter Modify the whole batch.
plugixatestimonial_ai_provider_config filter Override provider settings at runtime.

Cost estimation

Rough costs per batch of 10 testimonials with gpt-4o-mini at default settings:

  • ~3,000 input tokens (topic + instructions).
  • ~2,000 output tokens (10 testimonials).
  • Cost: ~$0.002 USD.

The URL / PDF flows add input tokens proportional to document length.

Tips

  • Be specific with the topic. “SaaS invoicing tool for freelancers” beats “software.”
  • Use URLs for existing products. The scraper pulls real product info that grounds the testimonials.
  • Adjust tone and temperature. Professional tone + lower temperature for B2B; casual + higher temperature for consumer products.
  • Review and edit. AI content should always be reviewed before publishing.
  • Import as Draft first. Set status to draft or pending so you can review in the standard approval workflow.

Troubleshooting

“API error 401”

API key is wrong or revoked. Regenerate in the provider dashboard and re-save.

“API error 429”

Rate-limited. Wait, or upgrade your provider plan.

Generated testimonials are generic

  • Raise topic specificity.
  • Provide more context in the prompt.
  • Lower temperature to 0.5 for less variation, or raise to 0.9 for more.

URL scraping returned nothing

Some sites block scrapers. Try saving the page as PDF and uploading instead.

“File too large”

The 5 MB limit is enforced. Split a large PDF, or filter with plugixatestimonial_ai_max_file_size.
