How Hosiqo compares and tests toolsFinal recommendation
Shortlist Buzz when transcribing recorded meetings, interviews, podcasts, or lectures offline matters most, and Simmie when drilling pricing and other objection-handling responses against an ai buyer matters most. Trial each on a few real meetings before you commit — the better fit usually shows fast.

AI sales roleplay platform where reps practice realistic buyer conversations and get automated scoring and coaching.
Buzz is a widely used open-source desktop application that transcribes and translates audio offline on the user's personal computer, powered by OpenAI's Whisper. It is MIT-licensed and actively maintained, with v1.4.4 released in March 2026, and it has grown a large community with roughly 19.7k GitHub stars. Buzz runs on macOS, Windows, and Linux, with installation options including Flatpak, Snap, and PyPI. It supports both importing existing audio and video files and real-time transcription from microphone input, and it can export results in formats such as TXT, SRT, and VTT for subtitling and documentation. The app includes an advanced transcript viewer with search and playback controls, a watch folder for automatically transcribing new files, and a command-line interface for automation. It offers GPU acceleration through CUDA for Nvidia cards, Apple Silicon support, and Vulkan for many other GPUs, which makes faster transcription practical even on laptops. Buzz also provides speaker identification and speech separation for noisy audio, plus a plugin system that adds capabilities like AI-generated summaries. Because all processing happens locally, recordings and transcripts remain on the user's machine rather than being uploaded to a cloud service. Pricing varies by plan. Check the official website for current pricing.

Simmie is an AI roleplay platform built for sales teams that want to scale conversation practice and coaching without relying on manager availability. Reps engage in simulated conversations with realistic AI personas that push back, raise objections, and adapt to what the rep says, allowing practice of cold calls, discovery, objection handling, demos, and other call types on demand. Every conversation is graded against a configurable rubric so teams apply one consistent bar for readiness, and an AI coaching layer delivers post-call analysis and targeted feedback or drill assignments. A builder tool converts existing scripts, playbooks, and call recordings into practice scenarios automatically, reducing the manual setup that traditionally limits roleplay programs. Simmie can be accessed through the web as well as through ChatGPT, Claude, Slack, and Microsoft Teams via MCP integrations, and it offers manager dashboards for visibility into rep readiness and skill gaps. The platform is SOC 2 Type II certified, includes regulatory-adherence detection features, and operates on a credit-based model where one credit equals roughly one minute of simulation. It is offered across individual, team, and enterprise infrastructure tiers and is actively operating in 2026. Pricing varies by plan. Check the official website for current pricing.
