Reply to Slack messages without typing a word
Keep up with fast-moving channels by speaking your replies. SpeakIn turns your voice into concise, clear messages that get the point across.
Sound familiar?
These problems disappear when you can speak instead of type.
Channel overload
You're in 30 channels, each with unread messages. By the time you type a reply to one thread, three more need your attention.
Over-explaining in text
What would take 10 seconds to explain verbally turns into a 5-minute typing session. You rewrite messages to avoid being misunderstood.
Meeting follow-ups
After every call, you need to type up action items and summaries in Slack. It feels like doing the meeting twice.

Speak naturally. Get polished text.
“Hey everyone so um quick update on the migration, we finished the database part yesterday and uh now we're working on the API layer, should be done by end of week unless we hit any blockers with the auth service...”
Quick migration update: Database migration complete as of yesterday. Now working on the API layer — on track for end of week. Only risk is potential blockers with the auth service.
“Yeah so the reason we did it that way is because like the old API didn't support batch requests and um we needed to process everything in parallel so we built a queue system that handles it...”
We built the queue system because the old API didn't support batch requests. We needed parallel processing, so the queue handles batching on our side.
