Apps we loveDecide with physics, before you pay for simulation.A physics-informed engineering screening workspace with live workbenches that re-solve results and sensitivity curves on every keystroke, plus a Simulation Studio running real 2D finite-difference field solvers (heat conduction, potential flow, process uniformity) in the browser. Includes saved runs with baseline comparison, report exports, Gemini-backed analysis chat, and a tutorial hub — built for fast early R&D screening, not as a replacement for validated CFD, FEA, process simulation, or physical testing.Phoenix EngineEngineering

MagicPen. An AI-powered document editor where you upload a document (or create one from chat) and describe changes in plain English — the assistant edits in place through block-level operations, so untouched headings, tables, links, and formatting survive byte-for-byte. It includes email/password accounts, import and export across PDF, DOCX, Markdown, HTML and more, document templates, a Review Mode for approving proposed changes, per-document change history with one-click restore, and a Slack bot plus a Google Docs add-on that connect to the same workspace.

Under the hood: Next.js 16 · React 19 · JavaScript · TipTap · Google Gemini API · MongoDB · Tailwind CSS · Supabase Storage · Slack API · Google Apps Script · JWT (jose) · Lucide React.
