How Hosiqo compares and tests toolsFinal recommendation
Shortlist Alter when freelancers and consultants privately capturing client calls without a visible bot matters most, and Second Nature when certifying reps on new messaging before a product launch matters most. Trial each on a few real meetings before you commit — the better fit usually shows fast.

AI role-play sales training software where reps practice live conversations with a conversational AI buyer and receive scoring and feedback.
Alter is a native macOS application that records, transcribes, and analyzes meetings directly on the user's Mac without sending a bot into the call. Instead of joining a meeting as a visible participant, Alter captures audio from the system output and microphone, so it works across Zoom, Microsoft Teams, Google Meet, WhatsApp, FaceTime, Skype, Discord, and in-person conversations. Transcription runs through on-device models, with a choice of an optimized Parakeet model for major languages or Whisper for broader language coverage, and speaker identification is performed locally. Because processing happens on the device, recordings and transcripts stay on the Mac and the app can operate without an internet connection. Beyond raw transcripts, Alter generates summaries and action items, lets users chat with their meetings, and connects to tools such as Notion, Slack, Linear, Asana, and Jira. It targets solopreneurs, freelancers, consultants, and other professionals who want private, bot-free meeting capture on macOS. The product is actively developed and operating in 2025 and 2026. Pricing varies by plan. Check the official website for current pricing.

Second Nature is an AI role-play platform that lets customer-facing teams rehearse sales conversations by talking to a conversational AI that responds in real time, rather than reading scripts or scheduling peer practice. Reps can drill pitches, discovery questions, and objection handling as often as they like until they reach fluency and confidence, with the AI providing scoring and structured reports against the behaviors a team cares about. A core selling point is fast content creation: the platform can generate realistic role-play simulations from existing sales material in minutes, and it supports many languages and conversation styles for global organizations. It integrates with CRMs including Salesforce and HubSpot so enablement leaders can tie practice to live workflows. Typical applications include shortening new-hire ramp time, certifying reps on new messaging ahead of product launches, and giving managers analytics on where individuals and teams struggle. Second Nature focuses squarely on the practice-and-coaching side of the sales-conversation lifecycle, complementing call-recording tools rather than replacing them, and is used by enterprise and mid-market sales organizations. Pricing varies by plan. Check the official website for current pricing.
