OhmNexus VS ContextForge.dev

OhmNexus's answer

It's built as a full electrical engineering authority, not a single-purpose calculator. Today that means conversions, wire/cable sizing, and battery calculators built to the actual standard (NEC/NFPA 70, IEC, IEEE) instead of a generic formula, with the math shown on the page rather than hidden. That's the early stage. The site is organized around roughly 26 categories mapping to real electrical engineering disciplines, and the roadmap runs into advanced design tools, in-depth guides, and eventually engineering design services, all built on the same standards-based approach from day one, working toward being a single reference point for the field rather than a scattered set of tools.

ContextForge.dev's answer:

ContextForge is memory that lives at the MCP layer, so it works across every AI coding agent at once — Claude Code, Cursor, GitHub Copilot, ChatGPT, and Windsurf — not just one. Save a decision once and any client recalls it later with semantic search. It goes beyond a note store: automatic git sync turns your commits and PRs into searchable knowledge, plus task tracking, snapshots, and team sharing — all through a single MCP server you add with one command.

OhmNexus's answer

Most sites in this space are a grab-bag of unrelated calculators bolted together. OhmNexus is being built discipline by discipline, roughly 26 categories that map to real electrical engineering fields, so coverage in any one area is deep and consistent instead of scattered. Every tool checks against the actual standard (NEC/IEC/AS-NZS) instead of a shortcut formula, and the math is shown, not hidden. That same foundation carries forward as the site grows from calculators into design tools, guides, and engineering services.

ContextForge.dev's answer:

Most memory tools are tied to a single agent or are just a key-value store. ContextForge is MCP-native, so it's portable across all your AI tools; it adds git sync so your codebase history becomes searchable context automatically; and it includes team features (shared spaces, collaborators) that solo-memory tools lack. Setup is one command, there's a genuine free-forever tier with no credit card, and paid plans start at just $9/month.

OhmNexus's answer

Today: electricians and contractors doing load calcs and wire sizing in the field, electrical/electronics engineering students checking work against real standards, and makers/DIYers on solar, RV, and battery projects. As the platform fills out across its 26 disciplines with design tools and reference guides, that widens to practicing engineers and designers who need standards-checked numbers without opening a full design suite, plus anyone evaluating engineering design services down the line.

ContextForge.dev's answer:

Software developers and engineering teams who use AI coding assistants — Claude Code, Cursor, GitHub Copilot, ChatGPT, Windsurf — and are tired of re-explaining their project, architecture, and conventions every session. It fits solo developers working across multiple projects as well as small teams that need shared, persistent context.

OhmNexus's answer

Electrical calculator sites online are almost all the same handful of unit converters repeated with different branding, none of them organized by discipline and none of them showing their formulas. OhmNexus started as an attempt to build the reference the field is actually missing: tools grouped by real electrical engineering categories, calculated to the actual standard instead of a shortcut, with the math visible on the page. It launched with the conversion and load-calculation basics built to that standard, and is being filled in from there toward guides, design tools, and eventually engineering design services.

ContextForge.dev's answer:

ContextForge was born from a simple frustration: AI coding agents forget everything the moment a session ends. Every new conversation meant re-explaining the same architecture, naming conventions, and past decisions. ContextForge was built to give AI agents a permanent, searchable memory through the Model Context Protocol — so knowledge is captured once and reused forever, across sessions and projects. It even dogfoods its own memory to help build itself.

OhmNexus's answer

A modern static-site architecture built for speed, with hand-built calculation logic per tool rather than a shared, generic math library, and standard cloud CDN hosting for global performance.

ContextForge.dev's answer:

Next.js 16 (App Router), React and Tailwind CSS for the dashboard, hosted on Vercel. Supabase (PostgreSQL) with pgvector powers the semantic vector search, and Deno edge functions serve the API. Embeddings use OpenAI text-embedding-3-small. The MCP client is a Node.js package (contextforge-mcp) on npm, implementing the Model Context Protocol.
