What Boon Cover Letter Builder is
Boon Cover Letter Builder is a web tool that helps users turn applicant details and a job posting into a tailored cover letter draft. Users can ask Boon in plain language to rewrite the letter, then keep, change, or undo its suggestions. Templates are designed to match Boon resume templates and share the same eleven colourways. Letters can be downloaded as Markdown or plain text on every plan; PDF downloads require a paid plan. Boon says a letter can stay in sync when someone moves between a computer, phone, and tablet.
The listed options are Free Start, Basic at $19.99 per month, and Premium at $49.99 per month. Free Start is free forever and includes AI credits at sign-up. Basic adds monthly AI credits and PDF downloads; unused credits roll over and do not expire. Premium includes Basic and a larger monthly AI credit allowance. However, the pricing comparison marks cover letters as “Coming soon” on all three plans. Boon describes its service as a companion for young professionals planning a career move. Users must be at least 18. The service says it encrypts content in transit and at rest, and does not use chats, files, or prompts to train its models.
