What Boon Cover Letter Builder is
Boon Cover Letter Builder is a web service that turns job and applicant details into a cover-letter draft tailored to a specific posting. You can ask Boon in plain language to rewrite the letter, then keep, change, or undo its suggestions. Its templates match Boon resume templates and use the same eleven colourways. Letters can be downloaded as Markdown or plain text on every plan; PDF downloads require a paid plan. Boon says work stays synchronized when you move between a computer, phone, and tablet. Plans listed are Free Start, Basic at $19.99 per month, and Premium at $49.99 per month, although the pricing comparison marks cover letters as “Coming soon” on all three. Free Start is free forever with sign-up AI credits. Basic adds monthly credits and PDF downloads, while Premium provides a larger monthly allowance. Boon says it does not use chats, files, or prompts to train models, and encrypts content in transit and at rest.
