Prerequisites and setup

NanoBanana runs entirely in-browser—no local GPU, Docker, or CLI tools required. You’ll need only a modern Chromium-based browser (Chrome 115+, Edge 115+, or newer), stable internet, and a MidassAI account with active Nano-tier access (free trial included). The workflow is built on MidassAI’s v2.4.1 inference engine, which bundles a fine-tuned multimodal vision-language model (NanoVLM-7B) optimized for e-commerce object understanding—not generic LMMs like Qwen-VL or LLaVA. This ensures reliable extraction of subtle product attributes: fabric weave visibility in knitwear, seam type in leather goods, or lens coating reflectivity in eyewear—all inferred directly from pixel-level analysis, not caption heuristics.

No API keys, environment variables, or backend configuration are involved. All processing occurs client-side after image upload; raw pixels never leave your device until you explicitly choose to export or share. Your brand voice settings (e.g., “technical but approachable,” “luxury minimalist,” or “Gen-Z playful”) are stored locally in browser IndexedDB and applied during post-processing—not during initial vision encoding—so tone consistency remains deterministic across sessions.

Extended prompt workflow

1. Upload & anchor: Drag a single JPEG/PNG (min. 1200×1200 px, front-facing, neutral background) into the NanoBanana interface. Avoid shadows, glare, or composite images—e.g., a matte-black ceramic mug shot at 45° on gray felt yields optimal attribute parsing vs. same mug floating over stock background.
2. Refine semantic scope: Toggle Detail Depth to “Precision Mode” (default: “Balanced”) when launching for B2B catalogs—this activates micro-attribute detection (e.g., “food-grade silicone gasket,” “IP67-rated seal”) and suppresses marketing fluff. For DTC social posts, select “Engagement Mode” to auto-generate 3 variant headlines + emoji-optimized bullet points.
3. Inject brand constraints: Paste your exact brand voice snippet (e.g., “Never use ‘revolutionary’ or ‘game-changing.’ Prefer active verbs: ‘locks,’ ‘stretches,’ ‘dissipates.’”) into the Tone Guard field. NanoBanana cross-checks every generated sentence against this rule set before rendering—rejecting 92% of tone-violating drafts in real time.
4. Select output targets: Choose ≥1 channel preset: “Shopify JSON” (includes metafields.product_type, tags, and SEO-ready title/description); “Xiaohongshu Markdown” (adds hashtag clusters like #家居黑科技 #小户型神器, line-break–optimized spacing); or “PDF Spec Sheet” (generates A4-layout with zoomed inset crops of key details like zipper pull texture or stitching density).
5. Validate & export: Preview all outputs side-by-side. Click “Verify Compliance” to run automated checks: GDPR-compliant alt-text generation, PANTONE color name fallbacks (e.g., “Navy → PANTONE 19-4052 TCX”), and banned-word filtering (configurable per market—e.g., “free” disabled for EU promotions). Export as ZIP containing all assets + versioned audit_log.json.

Common mistakes

• Using cropped or watermarked source images: Even 5-pixel borders or translucent logos confuse the vision encoder, causing false “embroidery” or “label text” extractions. Fix: Upload original, unedited camera output—crop only if background isn’t pure white/gray, and use the built-in background removal toggle instead.
• Overriding attribute fields manually before generation: Editing the auto-filled “Material” or “Dimensions” boxes before running the full workflow breaks dependency chains—e.g., changing “Cotton” to “Organic Cotton” without triggering recalculated care instructions. Fix: Always generate first, then edit outputs in the preview panel where linked fields (like “Wash Temp” ↔ “Fabric Type”) update synchronously.
• Assuming one-size-fits-all tone settings: Applying the same “friendly” voice to both technical B2B spec sheets and TikTok captions creates jarring dissonance. Fix: Save distinct voice profiles per use case (“B2B_Tech_Spec”, “TikTok_Urban”) and load them before uploading—NanoBanana tailors syntax depth, terminology density, and sentence length accordingly.

Try this in MidassAI

You can execute the exact NanoBanana workflow described above—no setup, no credit card—in under 30 seconds. Go to MidassAI Nano Studio → click “Start New Workflow” → select “NanoBanana: Photo-to-Page” → upload your product image → adjust Detail Depth and Tone Guard as needed → hit “Generate.” All outputs render instantly in your browser; no waiting for queueing or server-side rendering. Export options appear immediately upon completion—including direct Shopify CSV upload prep and one-click Xiaohongshu copy-to-clipboard with embedded image placeholders. For teams managing >50 SKUs/month, enable “Batch Mode” (in Settings) to process up to 12 images sequentially with shared voice rules and unified PDF naming (SKU-001_v2_spec.pdf, SKU-002_v2_spec.pdf).
