Twitter/X Content Image Generator#

Create post images, thread headers, and link preview cards optimized for Twitter/X's algorithm and visual standards.

Workflow#

Step 1: Understand the Content Goal#

Ask (if not provided):

• What type? (single image post / thread header / link preview card / poll graphic)
• What niche? (tech, business, creator, news, meme)
• Goal? (engagement, clicks, followers, brand)

Step 2: Apply Algorithm-Aware Decisions#

Read references/algorithm.md for:

• Image post vs text-only performance differences
• Thread optimization strategies
• Engagement patterns by content type
• Avoid suppression triggers

Step 3: Apply Visual Style#

Read references/design-style.md for:

• Style selection by niche
• Color palette and typography rules
• Layout patterns per format
• Dark mode considerations (most Twitter users use dark mode)

Step 4: Generate with Rendshot#

Post Image (1200x675):

text

generate_image({
  prompt: "Twitter post image for a tech announcement, dark theme, bold white title 'We just shipped v2.0', subtle gradient background, modern sans-serif, minimal and impactful",
  platform: "twitter_post",
  locale: "en"
})

Link Preview Card (1200x628):

text

generate_image({
  prompt: "Twitter card for a blog post about React performance, dark blue tech aesthetic, title 'React Renders Explained', code snippet preview, clean layout",
  platform: "twitter_card",
  locale: "en"
})

Thread Header:

text

generate_image({
  prompt: "Twitter thread header image, 'How I Built a SaaS in 30 Days', numbered badge '1/12', dark background with cyan accent, bold modern font",
  platform: "twitter_post"
})

Using templates:

text

list_templates({ platform: "twitter_card", q: "blog post" })
get_template({ template_id: "tpl_xxx" })
generate_image({ template_id: "tpl_xxx", variables: { ... } })

Step 5: Save for Brand Consistency#

text

create_template({
  name: "Product Launch Tweet",
  html: "<returned html>",
  variables: [...],
  platform: "twitter_post",
  tags: ["launch", "product", "announcement"]
})

Key Principles#

• Dark mode first: ~80% of Twitter users use dark mode. Design for dark backgrounds.
• Bold and scannable: Users scroll fast. Large text, high contrast, minimal elements.
• One message per image: Don't cram multiple ideas. One clear takeaway.
• Text-to-visual ratio: Twitter favors images with less text overlay. Keep it punchy.
