Features

Built for people drowning in red dots

One manager's core complaint: "I know I replied there recently — I just can't find the thread." whatsnext fixes that.

Find that thread

Describe it in plain words — "the thread where Priya pushed back on the Q3 budget" — and get ranked threads with deep links, powered by on-device semantic search.

My conversations

Your auto-maintained working set, split into On my plate and Everything else — with waiting on you badges and one-line summaries.

Recap any link

Paste a Slack link → neutral summary, each party's position, open questions, and 3 ready-to-send reply drafts. Thread memory shapes future recaps.

Always fresh

Syncs on launch, on window focus, and every 5 minutes while open — with a live countdown to the next auto-sync and a manual Sync now anytime.

Keyboard-first

1/2/3/4 switch views, j/k navigate, / search, ? shortcuts. Dark & light themes included.

Local message store

Your messages and search index live locally on your Mac. Recaps go only to the model endpoint you configure.

Privacy by design

Your messages stay on your Mac

whatsnext syncs your Slack history onto your Mac and builds its search index locally — there is no whatsnext cloud. When you ask for a recap, only that specific thread is sent to the Anthropic-compatible LLM endpoint you choose (Kimi, or any compatible API), with your own API key.

  • Local message store — your history stays on your machine, under your control.
  • On-device search — semantic search is computed locally, no cloud service needed.
  • Customizable model endpoint — bring your own base URL, API key, and model.
  • Your token, your scope — a Slack user token indexes exactly what you can see. Nothing more.
