Cursor use cases: 19 real examples

The draft was usable but weaker than accepted NSF summaries; thinking mode helped, though it began hallucinating and misreading the sources.

Cursor drafted an article on their reading trends in their style, citing Kindle highlights from the vault. The author edited it by hand.

Provisioning worked after two fixes. The MCP hid the real errors, so apply ran through Cursor's Run tool, which suggested the fix.

The agent finished the page in about 5 minutes; the author reviewed the PR, tested locally, and merged it to production.

Twelve demoed workflows, including a KPI model turned into a web app and no-code Jupyter analysis; no time or money figures are given.

A messy one-line note became a 2000-3000 word newsletter plus LinkedIn and Twitter drafts; the post itself says it was generated this way and published.

One prompt produced the thumbnail section with accurate colours, layout and button hover states, and it beat the earlier Lovable attempt built from static images.

The author migrated 10+ Lambda functions from Node.js 14 to 20 in one pass and fixed a broken docker-compose file by auto-retrying until clean.

A playable game with four minigames, persistent high scores, and no external dependencies was built in a couple of hours, with source code on GitHub.

The author shipped 120 models, an MCP server for Claude Desktop, and 140 chaos tests with a 100% pass rate over 22 months.

In 30 seconds it returned top complaints ranked by frequency, a severity versus frequency matrix, and a user journey map showing where frustration peaks.

After the author added the suggested indexes, page load performance improved significantly in production.

The agents wrote over 1 million lines of code across 1,000 files, and a three-week Solid to React migration reached +266K/-193K edits.

The agent rebuilt readable Go source from the stripped binary, but got some route paths wrong, such as /my-messages instead of /me/messages.

The repo shows sample decks, Word documents, and Excel workbooks, all created by agents with no templates and no manual editing.

The author upgraded kentcdodds.com across all dependency tiers, finishing a Remix v2 to React Router v7 migration with routing matching the original structure.

A working pipeline that outputs picks, performance metrics and a chart, with a 63-day backtest against an equal-weight benchmark and a test suite.

The author says the setup saves hours every week and keeps daily notes consistent, though no measured figures are given.

Prototyping, code completion, commenting and documentation earned A grades; web scraping, code tidying and getting started got D; dataframe manipulation and code generation got C.
