Clear for Slack is an AI Slack message writer designed for mobile-first professionals who need to communicate clearly from their phones. It turns rambling voice memos into short, scannable Slack messages that teammates can read in seconds, eliminating the burden of listening to long audio clips. The app also works with a simple /clr command for typed messages, making it a versatile tool for both mobile and desktop users. Its core value lies in transforming rough drafts into polished, action-oriented text without losing the original intent, tone, or key details like names and acronyms.
The concrete problem Clear solves is the pain of receiving long voice memos in Slack. When someone records a three-minute ramble while walking to a meeting, teammates have to stop working, put on headphones, and scrub through the audio to find the actual request. Many will skip it entirely, and those who listen spend more time than the sender spent recording. This creates friction, delays decisions, and wastes time. Clear eliminates this by converting voice notes into text that can be skimmed and replied to in a few seconds, restoring async communication efficiency.
Clear’s first major feature is voice note recording directly within Slack’s mobile app. Users open Slack, DM the Clear bot, and hold the microphone to record a voice note just like leaving a voicemail—no script or editing needed. Clear then transcribes the audio and uses fine-tuned language models to rewrite it into a concise, scannable message. Technical terms, acronyms, and names stay intact, preserving the sender’s voice. The refined text appears as an ephemeral response visible only to the sender, who then copies and pastes it into the desired channel. This feature lets mobile workers stay productive while walking, commuting, or moving between meetings, keeping their team updated without burdening them.
The second major feature is the /clr text command, designed for desktop users. Typing a lengthy or disorganized message in Slack? Just prefix it with /clr in any channel or DM, and Clear returns a cleaner, more direct version. Only the sender sees the refined draft, so the team never witnesses the rough draft. This feature extends the same clarity benefits to typed messages, making it easy for anyone to improve their communication without leaving Slack. It works in private channels and DMs, and the original message is not stored or shared. The /clr command is especially useful for drafting sensitive or complex messages before sending.

Additional capabilities include optional inline coaching, audio deletion, and multi-language support. Each refinement comes with a short note explaining what changed—like removed filler words or rephrased sentences—allowing users to learn and improve their writing over time. Coaching can be turned off if not needed. Voice notes are automatically deleted after transcription, and no audio or text is stored or used for training, ensuring privacy. Clear also works in almost any language, even preserving mixed-language sentences. This makes it ideal for global teams where English may not be everyone’s first language, as it maintains the original meaning while enhancing clarity.
Clear’s workflow is straightforward: record or type a message, let the AI refine it, then one-click paste to send. On mobile, the process starts by DMing the Clear bot and holding the mic; on desktop, typing /clr. The app routes each message to the best available model from Anthropic or OpenAI, using an optimized prompt for directness and clarity. The refined output appears as an ephemeral message that only the sender can see. The sender then copies the text and posts it to the intended channel or DM. The original audio or rough text is discarded immediately after processing. This workflow ensures that the team only ever sees the polished version, while the sender retains full control over what is posted.
Concrete use cases for Clear include a project manager who records a status update while walking between meetings; the team receives a clear, bullet-point summary in seconds instead of a long voice memo. Another scenario is a remote engineer who uses /clr to refine a technical question before posting in a busy channel—the message is clearer and gets answered faster. For international teams, a colleague dictating in a mix of English and Spanish gets a coherent message that preserves both languages. New hires can use the coaching tips to adapt to the team’s communication style more quickly. In each case, the outcome is reduced friction, faster decision-making, and less time wasted deciphering unclear messages.
Clear targets mobile workers, remote teams, busy managers, sales representatives, and anyone who relies heavily on Slack for daily async communication but struggles with rambling messages or voice memos. It works on iOS and Android via the Slack mobile app and on any desktop using the /clr command. The app is free during beta; after beta, pricing is expected to be around $1.99 per Slack user per month. Clear is installed by clicking the “Add to Slack” button and authorizing the workspace. The primary takeaway is that Clear transforms Slack communication by making messages shorter, clearer, and more actionable, helping teams actually read and respond to updates without unnecessary overhead.
Clear for Slack is designed for mobile-first professionals, remote workers, field sales representatives, busy managers, software developers, and anyone who relies heavily on Slack for daily async communication. It especially benefits those who frequently send or receive voice memos but struggle with long, rambling messages that waste time. Teams with non-native English speakers also gain value from its multi-language support and clarity enhancements. The app targets Slack users who want to write clearer messages without extra effort and who need a private, efficient way to refine both voice and text communication on the go.
