Document 365 AI+ costs USD 99.99 per year and includes those features plus AI services such as auto-redaction, summarization, document review and paragraph translation. Both subscriptions offer a seven-day free trial. A lifetime license costs USD 119.99 per device and covers one desktop device, with offline work that does not require cloud uploads. Paid plans provide read-aloud text-to-speech. Refunds may be requested within 14 days after purchase, subject to store exclusions. KDAN PDF is powered by KDAN Mobile Software Ltd., founded in 2009 and based in Tainan City, Taiwan.

Launchpad is a free platform for open-source collaboration, with tools to build and publish software. Projects can host Git repositories, review and merge changes, and link code changes to bug reports. Bug tracking can also integrate reports from Bugzilla, Trac, GitLab, and Mantis. Teams can build and distribute Debian packages, snaps, rocks, charms, and OCI images; documented architectures include AMD64, AMD64v3, ARM, and RISC-V. Localization tools support importing, exporting, and sharing translations, while blueprints help track project ideas and work. Launchpad Answers supports community help requests and FAQs. Automation options include a REST-style API, the launchpadlib Python client, and webhooks. The platform is available through the web, Linux, API, and self-hosted options. Commercial projects can request private branches, bugs, teams, mailing lists, and PPAs, but these features require Canonical authorization. Security documentation describes least-privilege access, restrictive networking, and fine-grained permissions; it also says automatic security monitoring was not in place as of July 2023.
