Shortlist Exec when practicing cold calls, discovery, and objection handling safely matters most, and Scriberr when researchers and journalists generating diarized transcripts of recorded conversations matters most. Try them side by side on real calls before deciding — needs vary by team.

Exec is an AI roleplay and training platform designed to help sales reps, leaders, and support staff practice high-stakes conversations before they happen with real customers. Its core function is generating voice-based AI characters that simulate buyers and other counterparts, complete with industry context and customizable traits, so reps can rehearse cold calls, discovery, negotiation, and objection handling in unscripted, dynamic conversations. The platform supports custom scenario creation and includes screen-sharing functionality so reps can practice product demos and presentations, not just talk tracks. After each roleplay, Exec provides instant performance insights, including actionable improvement tips and an AI coach that can explain scores, surface growth areas, and run short follow-up sessions to work through specific gaps. For managers and enablement teams, Exec offers analytics dashboards tracking skill development over time, performance trending, leaderboards, certification, and integration with existing learning management systems. It maintains SOC 2 Type II certification and states it does not use customer data to train its models. Exec is aimed at enterprise sales and revenue teams that want to close the gap between training content and real behavior change through repeated, measurable practice. Pricing varies by plan.

Scriberr is an open-source, self-hosted audio transcription application aimed at people who want to keep recordings and transcripts on their own hardware. It uses the open-source Whisper family of models (via the WhisperX engine) to transcribe audio and video files entirely offline, with no requirement to send data to a cloud provider. The project is distributed under the MIT license and is packaged as a single binary, with a Go backend and a Svelte frontend compiled into the binary, while Python handles the underlying AI transcription. Beyond raw transcription, Scriberr can automatically detect and label different speakers (diarization), generate summaries using custom prompts, and let users chat with a transcript by connecting to Ollama or OpenAI-compatible providers. It includes a transcript reader with playback follow-along and seek-from-text, a built-in audio recorder, note-taking, and a folder watcher plus API endpoints for automation and integration with tools like n8n. The maintainer publicly noted development is paused but not abandoned, and community contributions are welcome; the most recent release at the time of review was v1.2.0 in December 2025. Pricing varies by plan. Check the official website for current pricing.
