A privacy-first email client with built-in AI writing help
Pull Gmail, Outlook, Exchange, IMAP and POP accounts into one organized view so every message is in a single place.
Summarize long threads, draft replies in your voice, rewrite for tone or length and translate messages without leaving the inbox.
PGP and S/MIME support with keys you generate or bring yourself, plus tracker blocking and a zero-knowledge privacy stance.
Automatic grouping keeps noise down, while the Later board lets you park messages and pick them up when they are relevant.

Full-lifecycle RFP intelligence with deterministic accuracy and grounded AI
Pull opportunities from SAM.gov, eBuy, Find a Tender, and other sources, then score contract fit and run AI win-theme and past-performance analysis.
A rules-based engine shreds requirements, builds compliance matrices, flags liability and risk language through dictionaries and watchwords, and compares versions with 100% repeatable, audit-ready results.
A Prompt Library and approved Collections give teams a running start on competitive intel, win themes, and past performance, with every answer grounded in approved content and cited to source.
Customizable Kanban stages, tasks, reviewers, and comments keep proposal work moving from initiation through red team to submission on one source of truth.
