What they did

A builder made a tracker that puts 18 coding tools (Cursor, Claude Code, Copilot, Codex and more) side by side and logs every pricing change with sources.

Result (as claimed)

Public tracker launched.

Tools they used

Cost: Cursor: free plan, paid from $8/mo; Claude Code: free plan, paid from $17/mo; GitHub Copilot: free plan, paid from $10/mo; OpenAI Codex: free plan, paid from $8/mo. Checked 2026-10-14.

Set it up

  1. Gather your sources

    Collect the papers, notes, links or files you want to work from in one place.

  2. Load them into the tool

    Open Cursor, Claude Code, GitHub Copilot, OpenAI Codex and add your sources. Keep the original files so you can check claims later.

  3. Ask focused questions

    Ask for summaries, comparisons or connections with citations to the source passages.

  4. Verify and save

    Spot check claims against the sources, then save the output as notes you can reuse.

Copy the full setup prompt

Paste into your agent and it will walk you through the setup, asking before anything that sends, posts or spends.

You are helping me set up this AI use case end to end in Claude Code.

Please:
1. Ask me 3 short questions about my situation (accounts I have, budget, what I want the output to look like).
2. Propose a step-by-step plan using these tools or cheaper alternatives, with the time and cost of each step. Use official pricing pages; say "check pricing" if unsure.
3. Then do the setup with me one step at a time, waiting for my OK before anything that sends messages, posts publicly, spends money or deletes data.
4. Finish with a checklist to run it again next time.
