Say a Kind Word is a free group card for coworkers. Start a card, share one link, and everyone adds a note in about 20 seconds, with no accounts for anyone. Notes stay hidden until you deliver the card as a surprise. New: a free Slack app—type /saykindword to start a card in your channel and send a one-tap last call. Free to make, sign and deliver, with no ads. A paid Premium Card is on the way, and the free card stays free. English and Spanish.
