Developer Building Next.js Whiteboard App Seeks Free Vision API to Generate Image Prompts from Drawings
A developer is building a Next.js whiteboard app using tldraw. Users draw on a canvas, type a prompt, and click Enhance. The app exports the canvas as base64 PNG and sends it to an AI vision model to generate a detailed image prompt. That prompt is then used with Pollinations.ai to generate a refined image. The developer needs a free vision API that accepts base64 image and text prompt, returns text, and works without a credit card. They tried OpenRouter but encountered model routing issues and are seeking alternative reliable free models such as Gemini, LLaVA, or others.
