Letty

Letty is an AI email writer for drafting and refining professional messages by goal, tone, and context. Users should correct names, commitments, dates, confidential information, and tone before sending and should not automate impersonation or deceptive outreach.

Users begin with a limited test, provide only authorized and necessary inputs, configure privacy and output settings, compare results with the original source or a trusted benchmark, correct errors, and keep a responsible person in control before publishing, sharing, or automating consequential work.

Free limited access is available and paid access starts from $9 per month. Messages, templates, features, and billing period vary.

AI output can be inaccurate, biased, incomplete, stale, or misleading and the service may process confidential or personal data. Protect credentials, review retention and model-training terms, respect copyright and consent, monitor costs and permissions, and add specialist review for regulated or high-impact uses.
