How Hosiqo compares and tests toolsFinal recommendation
Shortlist ColdCALR when new reps rehearsing cold-call scripts before dialing real prospects matters most, and Scriberr when researchers and journalists generating diarized transcripts of recorded conversations matters most. Trial each on a few real meetings before you commit — the better fit usually shows fast.

ColdCALR is an AI-powered cold-call training tool that simulates realistic outbound calling scenarios so sales professionals can practice their scripts and objection handling against AI-generated prospects. The AI plays the role of a prospect that raises objections, asks questions, and reacts in a way meant to mirror real conversations, letting reps rehearse repeatedly on demand without scheduling a live partner. After a practice session, ColdCALR provides objective, automated feedback and scoring on cold-calling technique and objection handling, helping reps see where their delivery and responses can improve. The tool includes a script builder for creating and refining cold-calling scripts, an analytics dashboard for tracking progress and appointment-setting metrics over time, and industry-specific templates with prebuilt scenarios for sectors such as real estate, SaaS, insurance, and recruiting. Notably, ColdCALR focuses on practice against AI rather than recording real prospect calls, which the product positions as a way to sidestep dual-consent recording concerns. It is aimed at individual reps, account executives, sales teams, and training directors who want low-pressure, repeatable cold-call 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.
