Search Slack Messages With Ease
Lightning-fast, typo-tolerant search for Slack that runs locally in your browser. Find the messages you've seen without sending your data to the cloud. Privacy-first, always.
Powerful Features
Everything you need to never lose track of important Slack conversations again.
Typo-tolerance
Misspelled a word? Prefer "optimisation" over "optimization"? No problem. Sleach finds both. Our fuzzy search locates what you meant, even with typos and misspellings.
Suggestions
Looking for a keyword clue? Just start typing to get instant suggestions.
Privacy-focused
All indexed messages are stored and kept locally in your browser storage. No cloud storage, no data collection.
Fast
Instant Search Results: Experience sub-100ms response times.
Realtime indexing
New messages are indexed automatically as you scroll. Always up-to-date—no manual refresh needed.
Space efficient
Only a message preview (up to 140 characters) is stored. Clicking a search result opens the original message directly in Slack.
How It Works
Simple, powerful, and completely private. Here's how Sleach transforms your Slack experience.
Typos and different spellings
Typos and misspellings are tolerated.
Advanced search criteria
Narrow down your search by choosing additional parameters and a timeframe (today, yesterday, last 3/7/30 days).
Attachment name search
Search also includes attachment names (and you can use an additional search filter: "Has files").
Search suggestions
Forgot a word? No problem – just start typing to see suggestions ranked from the rarest to most popular.
Forwarded message search
Forwarded messages are also indexed. This means you can find a forwarded message even if you haven't seen the original.
Space efficiency
Only a couple of dozen megabytes for several thousand messages.
