Audio and video to text service offering automatic and human-verified transcripts and subtitles.
Berlin-based sales performance intelligence platform that analyzes real sales calls, surfaces skill gaps, and delivers AI coaching and roleplays, using GDPR-compliant on-device transcription.
Amberscript is a speech-to-text service that converts audio and video into text and subtitles, offering both automatic AI transcription and human-verified options. Users upload recordings and choose between editable automatic transcripts produced by speech recognition or expert-reviewed transcripts refined by professional editors for higher accuracy. The platform similarly provides subtitles in either automated or professionally edited form, including translation services, and offers a transcript editor for reviewing and correcting output. Amberscript supports a large number of languages and additionally provides a speech-to-text API and data annotation services, as well as a meeting transcription offering for capturing and converting spoken meetings into text. The combination of self-serve automatic transcription and a human-review tier lets users trade off speed against accuracy depending on the use case. Amberscript is aimed at researchers, media organizations, businesses, and public-sector users who need reliable transcripts and subtitles, including those with accuracy or accessibility requirements that justify human-reviewed output rather than automation alone. Pricing varies by plan. Check the official website for current pricing.

Zell is a Berlin-based AI platform that captures and analyzes real sales calls to give sales teams performance visibility and automated coaching. It works across video calls, phone calls, and in-person meetings, automatically evaluating call behaviors such as talk patterns, objection handling, and discovery depth, and producing scorecards and instant AI call summaries once conversations end. A skill-gaps dashboard helps managers see who is improving and where coaching is needed, while an AI coaching component (named Dave) generates personalized feedback, coaching plans, and roleplay simulations based on each rep's actual performance, then tracks improvement over time. Zell positions itself as a layer that turns conversation insights into action and automates much of the sales manager's manual coaching workload. As a European company founded in 2024, Zell emphasizes GDPR-compliant, on-device transcription that does not require a meeting bot or store customer data. The company has validated its model with clients across the US, Germany, Italy, and Spain and is backed by European pre-seed investors. It is a newer, privacy-focused alternative to large US conversation intelligence platforms. Pricing varies by plan. Check the official website for current pricing.
