RedInk: AI Xiaohongshu Post Generator — One Sentence Creates a Full Note 199

RedInk is an open-source AI Xiaohongshu image-and-text generation tool built by Gen-Z developer Mozi (@HisMax). After being open-sourced at the end of 2025, it quickly gained 4.5K+ Stars on GitHub. It generates copy with Gemini 3 and illustrations with Nano Banana Pro (Gemini 3 Pro Image Preview), focusing on "generating complete Xiaohongshu image-and-text posts from a single sentence," compressing the traditional 2-3 days of design work into under 10 minutes.

Core Features of RedInk

• Generate complete image-and-text posts from one sentence: Enter a topic description, and the AI automatically generates a full Xiaohongshu post including a cover and up to 15 pages of content, covering outline planning, copywriting, and illustration design.

• Smart outline editing: The system first generates a structured content outline. Users can freely adjust chapter descriptions, add or delete pages, and confirm before entering the image generation phase to prevent the AI from "going off track."

• Batch concurrent image generation: Supports a high-concurrency mode that generates 15 images simultaneously, shortening the original 7-10 minutes of sequential generation to 2-3 minutes.

• Single-page redraw with style consistency: Unsatisfactory individual images can be redrawn separately, and the AI automatically references the style of other pages to ensure visual consistency across the entire set.

• Reference image style adaptation: Upload brand homepage screenshots or reference images, and the AI learns their color tones, fonts, and composition features to generate customized content that matches the brand style.

• History management: Supports viewing, editing, and deleting past works. After closing the page, drafts can be retrieved from history for continued editing.

• Flexible configuration: Supports both a web visual interface and YAML file configuration, and can be integrated with multiple models such as OpenAI, Gemini, and DALL-E 3.

Use Cases of RedInk

• Xiaohongshu bloggers / self-media creators: Produce 10+ posts daily, covering sections such as beauty, fashion, travel, and food, solving the pressure of "daily updates."

• MCN agencies / content studios: Batch-produce standardized image-and-text content, reducing reliance on designers and copywriters, with the cost per post dropping from 500-1000 yuan to just API call fees.

• E-commerce sellers / brands: Generate product recommendation notes and review image-and-text posts, supporting brand logo placement and unified visual style, for traffic generation to Xiaohongshu shops.

• Events / poster emergencies: Quickly generate posters and introductory image-and-text content in urgent scenarios such as hackathons and competitions. Some users have already completed high-quality posters within half an hour and won awards using this.

• Cross-border e-commerce / overseas brands: Leverage Nano Banana Pro's Chinese and English text rendering capabilities to generate bilingual image-and-text content tailored for overseas markets.

Frequently Asked Questions about RedInk

Q: Can the generated content be published directly?

It is recommended to publish after manual review. The AI handles efficiency, and you bring the soul. Publishing low-quality, repetitive content directly may result in account throttling.

Q: Why does my Logo become distorted after page 3?

This is a known bug related to the AI's context length limitations. Single-page redraw or manual adjustment is recommended, and the author fixes issues extremely quickly.

Q: Which image generation models are supported?

The default is Nano Banana Pro (recommended), but DALL-E 3, Midjourney, etc. can also be configured, though their Chinese text rendering and style consistency are not as good as the former.

Q: Do I need programming experience?

Not at all. The official website provides a web interface, and technical users can also deploy it themselves through the open-source GitHub project.

Q: How is the generation speed?

Sequential mode takes 7-10 minutes for 15 images, while high-concurrency mode takes 2-3 minutes for 15 images. It depends on the concurrency limits of the API provider.

Q: How much free quota is available?

Signing up on the official website grants 50 credits, and using an invitation code grants another 50 credits, totaling 100 credits to start. You can also earn credits through daily check-ins and inviting friends.

Tutorial for Using RedInk

Step 1: Register and Configure

• Visit the official website redink.top and register an account (currently requires an invitation code)

• Go to the settings page and configure the text generation API (OpenAI/Gemini) and image generation API (Nano Banana Pro)

• Or configure via YAML files: edit text_providers.yaml and image_providers.yaml

Step 2: Enter the Topic

• Describe what you want to write in the input box, such as "3-Day Chengdu Food Travel Guide"

• You can upload reference images to maintain brand style consistency

• The more detailed the topic, the better the generation results. It is recommended to include keywords such as brand, product, and selling points

Step 3: Edit the Outline

• The AI generates a structured outline, including a cover and up to 15 pages of content descriptions

• You can add or delete pages and modify descriptions, then confirm to enter the generation phase

Step 4: Generate and Adjust

• Choose whether to enable high-concurrency mode (recommended for batch production)

• Wait 2-10 minutes for the complete image-and-text content to be generated

• Click "Regenerate" for unsatisfactory pages, and the AI maintains style consistency

Step 5: Export and Publish

• Supports batch downloading of all images

• View outlines and perform detailed processing on individual images

• Retrieve and continue working on past drafts anytime through history

Core Advantages of RedInk

• True "one-click" experience: Unlike tools that only generate text or only generate images, RedInk seamlessly integrates copywriting planning and visual design, outputting finished products from just a topic input.

• Native adaptation for Xiaohongshu: From UI design (red main color) to content sections (beauty, fashion, travel, etc.), from copywriting style (internet-savvy, emoji usage) to visual aesthetics (young female preferences), it deeply adapts to the platform's tone.

• Chinese text rendering capability: Nano Banana Pro clearly renders Chinese and English titles, price tags, and product information in images, which is a clear shortcoming of DALL-E 3 and Midjourney.

• Ultimate cost-effectiveness: Open-source and free plus low API costs enable individual bloggers and startup teams to achieve professional-grade content output at near-zero budget.

• Rapid iteration: Author Mozi responds extremely quickly, and bug reports from users are often fixed within the time of a single meal. The community is highly active.

Why Choose RedInk

If you are a Xiaohongshu creator or operator, struggling daily with "what to post today" and "how to create the illustrations," RedInk is currently the lowest-barrier and most efficient solution. It transforms the work of "writing copy + designing," which originally required two people and two days, into a task that one person can complete in 10 minutes. Although there is still room for improvement in template personalization and deep editing, for scenarios such as batch production, matrix account operations, and emergency image creation, its cost-effectiveness and output speed are unrivaled. In particular, Nano Banana Pro's Chinese text rendering capability ensures that the text in images is no longer "scribbles," which is crucial for domestic content creators.
