As answered by people managing OpenCV and CrochetPatternGen.
CrochetPatternGen's answer:
Next.js (static site on Cloudflare Pages), Python/Flask image-processing service (Pillow, NumPy), ONNX-based background removal (rembg/u2net), Docker on a small VPS, Cloudflare for CDN/WAF/DNS. No LLM in the chart pipeline — conversion is deterministic image processing.
CrochetPatternGen's answer:
We launched in July 2026 and focus on individual crocheters rather than named accounts — no big customers to list yet. Early users are hobbyist blanket makers and Etsy pattern sellers.
CrochetPatternGen's answer:
It started from a simple observation: people search "crochet cat pattern" thousands of times a month, but turning your own photo into a pattern still meant hand-tracing pixels or buying expensive custom patterns. At the same time, marketplaces were being flooded with AI-generated fake patterns that don't actually work. CrochetPatternGen was built to be the honest alternative — deterministic conversion instead of AI hallucination, with stitch counts and quality scoring so every chart is genuinely crochetable.
CrochetPatternGen's answer:
CrochetPatternGen doesn't draw patterns with AI guesswork — it converts real photos into stitch-ready crochet charts through deterministic image processing. Every chart comes with a controlled color palette and exact per-color stitch counts, so what you see on the grid is exactly what you stitch. It's also honest about what's automated: previews are labeled "digital preview" and AI-generated content is disclosed site-wide.
CrochetPatternGen's answer:
Three reasons: speed (photo to finished chart in under a minute, vs hours of manual tracing in chart editors), precision (per-color stitch counts that double as a yarn shopping list, which most generators don't provide), and honesty (no fake ratings, no undisclosed AI content, free tier that actually works without sign-up). It also covers five techniques — graphgan, C2C, tapestry, mosaic, and filet — including realistic C2C block proportions most tools ignore.
CrochetPatternGen's answer:
Crocheters who want to turn personal photos into blankets, pillows, and panels — mostly hobbyists making graphgans and C2C photo blankets, plus Etsy sellers who need fast, countable charts for custom orders. The typical user is a casual crocheter, not a designer: she has a photo she loves and wants to crochet it, without learning chart-editing software.
