How Hosiqo compares and tests toolsFinal recommendation
Shortlist Alter when freelancers and consultants privately capturing client calls without a visible bot matters most, and Koncert when managers coaching reps from recorded calls and a remote salesfloor matters most. Try them side by side on real calls before deciding — needs vary by team.

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.

Koncert is a B2B sales engagement platform built around AI-powered dialing, call recording, and coaching for outbound teams. Its dialer suite includes options such as an AI Parallel Dialer and an AI Flow Dialer that filter voicemails and connect reps to live answers to increase connected conversations and connect rates. Calls are recorded and run through conversation intelligence that scans for objections and other signals so managers can coach reps at scale, and a remote Salesfloor gives managers a virtual workspace for real-time coaching during calls. Koncert also includes a multi-channel cadence sequencer spanning phone, email, video, text, and social, plus caller ID management that selects local numbers and monitors number health. For practice and training, Koncert offers AI PitchLab, an add-on where reps rehearse pitches against AI-powered buyer personas without the pressure of a live prospect, with objection-handling practice and automatic transcription and scoring of performance. Together these capabilities target outbound sales teams, SDRs, and managers who want dialing, real-call analysis, and structured roleplay practice within one platform. Pricing varies by plan. Check the official website for current pricing.
