what AI can build

Build a chat app using Anthropic API, with document upload, conversation storage, and optional project contexts.

A Claude-like UI is trivial; the model, safety/reliability layer, long-context performance, artifacts/projects, and platform distribution are not.

The prompt was editor-reviewed; no completed build is recorded.

the prompt

Curated prompt
Build me a personal chat client on the Anthropic API to replace my Claude Pro
subscription with per-token billing. Requirements:

- A local web app: Node + Express + better-sqlite3, streaming replies over SSE,
  a conversation sidebar, Markdown rendering with marked.
- Anthropic API key in .env; model picker with Sonnet as the default and Opus
  on demand; system prompt editable and saved per project.
- Projects: a project groups conversations and holds a few reference docs
  (plain text or PDF via pdf-parse) prepended as context for every chat inside
  it.
- Use prompt caching on the project docs to cut token costs, the API supports
  it directly.
- SQLite FTS5 search across all conversations; export any thread to Markdown.
- A cost meter per conversation plus a monthly total from the API usage fields,
  so the keep-paying-or-not decision is a number, not a feeling.
- Localhost only, no accounts, no telemetry.
- Out of scope: artifacts, mobile apps, and agent features. If the cost meter
  shows heavy use, flat-rate Pro or Max wins; include that comparison logic in
  the README.
- README: key setup, a link to current per-token prices, and state that the
  model is the product; this wrapper only changes how I pay for it.

questions

Can AI replace Claude?

Not really. Claude's value is not just interface code — frontier Sonnet and Opus reasoning, 200k context adherence, and Claude Code tooling. See the honest breakdown above.

How much does Claude cost?

Claude is listed at about $20/month (Pro, checked 2026-07-30), or $240 per year. This is a pricing reference, not evidence of a completed replacement or realized savings.

What do I lose by replacing Claude?

Honestly: frontier model; long-context quality; product surface; mobile apps; reliability; continuous model upgrades. If any of those are load-bearing for you, keep paying.

Is there an open-source alternative to Claude?

Yes — LibreChat (Open-source multi-model AI chat platform for self-hosting API-based assistants.). Using prior art is also a valid exit; the prompt is for when you want it exactly your way.
