Slacksift

What is Slacksift ?
Slacksift is a Slack app that summarizes long threads so you can catch up without scrolling through dozens of messages. When you get tagged in a busy conversation, you run one command and get a concise recap of what happened.
The workflow is built around Slack mentions. After installing the app to your workspace, you run @slacksift setup once to connect billing, then use @slacksift summarise inside any thread you need summarized.
It fits teams that live in Slack and regularly get pulled into threads they did not follow from the start. Project leads, managers, and anyone who needs quick context before replying will get the most out of it.
SumlyAI

What is SumlyAI?
SumlyAI sends personalized podcast summaries to your inbox after new episodes drop. You build a profile with your interests and goals, pick shows to follow, and receive takeaways framed for your context instead of generic bullet recaps.
Most summarizers compress episodes into the same highlights for every listener. SumlyAI filters for mental models and actionable advice tied to your profile, delivers within 12 hours of release, and targets a morning briefing workflow so you can skim a 3 minute note instead of a 2 hour episode.
It fits founders, operators, and lifelong learners who subscribe to long-form shows but forget details by the next week. The homepage lists 1,017+ users, a free plan with no credit card required, and a 14 day free trial on the Premium Starter tier.
