ToneBird

ToneBird is a desktop AI reply assistant for Mac and Windows that drafts replies directly inside the apps a person already types in — Gmail, Slack, WhatsApp, and others — instead of requiring a separate chat window. It remembers the relationship and conversation history with each contact, pulling relevant facts (like an agreed price from a connected file) into the drafted reply, and adjusts tone per person rather than producing one generic style. Users open it with a keyboard shortcut (Option twice on Mac, Ctrl twice on Windows), compare a few draft replies, tweak the chosen one, and insert it before sending — ToneBird never sends a message on its own. It also surfaces a running list of promised follow-ups and unanswered questions pulled from past replies, and can draft calendar events from a conversation once a time is agreed. Pricing is free for light use (15 replies/day, 30 contacts), with Standard and Pro tiers raising daily usage and contact limits, plus a custom Enterprise tier.
