How Hosiqo compares and tests toolsFinal recommendation
Shortlist Alter when freelancers and consultants privately capturing client calls without a visible bot matters most, and PowerDialer.ai when sales managers reviewing recorded and transcribed calls to coach reps 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.

PowerDialer.ai is an AI-powered outbound calling platform aimed at small and mid-sized B2B sales teams, call centers, and high-volume prospecting groups. Its core is a dialer that supports multiple modes, including power dialing for sequential calls, parallel dialing that places several simultaneous calls and connects a rep to the first prospect who answers, and predictive dialing, alongside ringless and AI-personalized voicemail with voice-cloning capabilities. Layered on top of the dialer is a set of AI features relevant to revenue intelligence: calls are automatically recorded, transcribed in real time, and analyzed to identify winning talk tracks, with AI-generated summaries of conversations and instant coaching suggestions for reps. The platform also includes performance analytics and dashboards that track calls, connects, and meetings, identify high-converting personas, and surface optimal calling times. It integrates with CRM systems to log activity and keep records in sync, and it is marketed with flat-rate pricing that avoids per-seat penalties. The product positions itself as an affordable alternative to higher-priced parallel dialers, targeting teams that want fast setup, conversation recording, and AI coaching without enterprise complexity. Industries highlighted include B2B sales, real estate, financial services, healthcare, legal, and automotive sales. Pricing varies by plan. Check the official website for current pricing.
