Is it easily extensible? For instance, when chunking PDF-converted-texts, is it possible to apply transformation or attach metadata to chunks?

As someone who has two annual subs of Cursor Pro (one from student account and another from Lenny's newsletter), I just spent $100 on Claude Code and I haven't touched Cursor AI for any coding tasks since. If you already spend anything near or over $100 on Cursor, it's no brainer. The agent experience is night and day. No more wrong tool-calling, premature ending of conversation, failure to apply changes or overwriting a whole file with the update snippet. I'm considering upgrading to $200 Claude Max next month for more concurrent sessions. If anyone reading this thinking this is a paid comment, go search for other users' feedback. Claude Code is that good.
