Wispr Flow

An AI voice-dictation application ("Voice OS") from Wispr AI that turns natural speech into polished, formatted text across virtually any app on desktop and mobile.

A hold-to-talk shortcut works in any text field across macOS, Windows, iOS, and Android. Audio is transcribed in the cloud and AI-cleaned (removes filler words, auto punctuates/capitalizes, structures lists, adapts tone per app). Command Mode (Pro) lets users voice-edit highlighted text ("make this concise," "translate to Polish"). Supports 100+ languages with code-switching.

Core is its speech-to-text + AI cleanup pipeline (reportedly using an OpenAI subprocessor for transcription plus a fine-tuned Llama model for cleanup, hosted on AWS via Baseten). Claims ~10% error rate (vs. higher for generic dictation). Building proprietary voice-first foundation models. No MCP server; this is an input tool, not an integration platform.

Per-seat subscription. A free tier plus paid plans roughly in the $12–$15/user/month range (Pro). Enterprise plans available with additional security (SOC 2 Type II, auto-enabled privacy mode).

Works system-wide across apps (not via discrete integrations); a closed API has been tested with select enterprises/hardware partners.

SOC 2 Type II (Enterprise; 2026 re-attestation in progress via Drata/A-LIGN), ISO 27001:2022, HIPAA BAA available on all plans, GDPR/CCPA aligned, ISO 42001 (AI governance) alignment claimed. Privacy Mode (zero data retention) is opt-in for Pro, auto-enabled for Enterprise; without it, dictation data "may be used to evaluate, train and improve" the product.

Wispr AI Inc., founded 2021 in San Francisco by Tanay Kothari (CEO) and Sahaj Garg; originally a wearable hardware company before pivoting to software. Flow launched on macOS October 2024. Raised $81M total ($30M Series A led by Menlo Ventures, June 2025; $25M extension led by Notable Capital, November 2025) at a $700M post-money valuation. Bloomberg reported on May 12, 2026 that Wispr was in talks to raise ~$260M led by Menlo at a ~$2B valuation (not finalized). ~2.5M downloads; used at 270 of the Fortune 500.

Productivity tool for individuals — faster drafting of emails, memos, notes, and messages by voice (claimed ~4x faster than typing). Useful for investors who write heavily. Not a data/sourcing tool.

Cloud-dependent (offline tools run locally; vendor outage/acquisition risk); AI cleanup can over-edit/alter verbatim meaning; reported high RAM/CPU usage on the Windows (Electron) app; for sensitive content, privacy mode must be enabled (default training use otherwise); compliance re-attestation reportedly in progress.
