Calque: a shared canvas where architects review drawings together, now with AI concept edits and a board agent

What it is: a browser workspace for architecture and interior studios. You bring plans and references onto shared sheets, measure at scale, comment on the drawing itself, and agree the next revision with your team or client. What's in the video (a real run, not a mockup): A plan on an A3 sheet, the existing kitchen photo and a material board beside it Edit with AI on the photo: a prompt, the material board attached as a reference, and the price shown up front.

痛点:建筑与室内设计工作室的图纸评审流程散落在 Miro、PDF 标注工具和聊天软件中,导致通用画布对图纸不够精确,PDF 工具又缺少实时协作与设计讨论能力。

目标用户:建筑和室内设计工作室的设计师、项目负责人,以及参与评审的甲方客户

证据:"a friend's studio ran design reviews across Miro, a PDF markup tool and chat. Canvas tools aren't precise enough for drawings, and PDF tools aren't collaborative enough for design conversations." / "Where it's at: early access and free for now. I haven't validated willingness to pay"

变现:按坐席订阅的工作室团队版(按席位订阅),把 AI 概念编辑按次计费(帖中已做到"price shown up front"),并把大尺寸图纸导出、版本历史和私有上传作为付费层级。

MVP:两周内只做图纸评审的最小闭环:上传 PDF/DXF 到共享画布、按比例测量、在图面上打点评论并支持 @提及、版本并排对比、按顺序导出 PDF;AI 概念编辑和 board agent 先砍掉,先找 3-5 家工作室取得真实试用反馈来验证付费。

竞品:Miro、Bluebeam Revu、Autodesk Construction Cloud (BIM 360)、Morpholio Trace、Figma/FigJam、SketchUp LayOut

摘要:独立开发者发布 Calque,一个面向建筑与室内工作室的浏览器协作画布,支持 A3 图纸按比例测量、图面评论 @提及、实时协作和有序 PDF 导出,并用 Google Nano Banana Pro 做基于材料板的 AI 概念改造,以及用 board agent 生成对比方案图纸。技术上用 React + TypeScript 跑在 Cloudflare Workers 上,配合 Durable Objects 实时同步,并自研编辑器替换了授权画布库。目前处于免费 early access,作者明确承认"还没验证付费意愿",痛点来自一位朋友的 studio 用 Miro+PDF 工具+聊天拼凑评审流程。
