Whisperstream is a privacy-focused Windows dictation app that turns speech into text entirely on-device, with no cloud upload.
Acta.ai is an AI meeting assistant developed by Agilean Solutions Private Limited, an India-based company. It connects to a user's Google or Microsoft account and calendar, and its agent automatically joins scheduled meetings on Google Meet, Microsoft Teams, and Zoom. After a meeting, Acta.ai records and transcribes the conversation and then analyzes it to generate a concise summary, a list of decisions, and actionable tasks. A distinguishing element is its persona-based approach: the platform offers domain-specific agents oriented toward business functions such as Sales, Engineering, Recruiting, Project Management, Finance, Customer Support, and HR, with the ability to convert discussions into role-appropriate outputs like product requirement notes, ticket-style items, deal briefs, or assessment reports. It also includes an 'Ask Acta' assistant for querying meeting content and provides a Chrome extension. Acta.ai is positioned for cross-functional teams that want meetings translated into structured follow-up work rather than only a raw transcript, and it markets itself around moving from 'what was said' to 'what needs to be done.' The product is actively operating, offering a free trial alongside paid tiers. Pricing varies by plan. Check the official website for current pricing.

Whisperstream is a downloadable Windows desktop application from Lanreal Technologies Inc. that converts speech to text using push-to-talk dictation. Transcription runs entirely locally on the user's PC via the NVIDIA Parakeet model, so audio is never uploaded to the cloud and no account is tied to the user's voice. It works across any application without add-ins or setup, inserting dictated text directly into tools such as Outlook, Gmail, Slack, VS Code, browsers, and Claude Code. Beyond live dictation, it can import and transcribe existing audio recordings, and it keeps a searchable transcript history with audio replay, encrypted on the device. Additional features include AI cleanup that tidies spoken input, a custom vocabulary for names, jargon, and acronyms, per-app custom AI prompts, support for 25 languages, global keyboard shortcuts, and full offline operation. It requires Windows 10 or 11 (64-bit) with at least 8GB RAM. It targets professionals and privacy-conscious knowledge workers who want fast, local voice input rather than typing.
