Not much, and most of it is free. You need:
- A computer and internet.
- A place to track roles: Notion or Google Sheets. Both are free.
- An email account for job alerts and applications. A free Gmail works.
- Your current resume, in a document you can edit.
- A LinkedIn account. Free is fine, and it matters most, since the networking runs through it.
- A Claude paid plan. Pro is $20 a month, or $17 a month billed annually. It runs the tailoring and drafting. The free tier is too limited for daily use.
Your only required cost is Claude, about $20 a month. Everything else can be free.
