AI sales roleplay platform where reps practice realistic buyer conversations and get automated scoring and coaching.
Callabo (콜라보) is an AI meeting assistant developed by Return Zero (리턴제로), a Korean speech-AI company. It automatically records, transcribes, summarizes, and analyzes business meetings for both individuals and enterprise teams, aiming to turn a one-hour meeting into organized notes with a single click and no complex setup. Callabo connects to online meetings on Google Meet, Microsoft Teams, Zoom, and Webex, and also supports recording in-person meetings. After a meeting it produces transcripts, paragraph summaries, key discussion points, and action items with timestamped source quotes, and it can automatically detect the meeting language to handle multilingual conversations. An AI chat feature lets users ask follow-up questions about a meeting beyond the generated insights. The service integrates with workflow tools including Google Calendar, Outlook, Salesforce, Pipedrive, HubSpot, Slack, Microsoft Teams, Zapier, Notion, Confluence, and Linear. For enterprises, Callabo provides meeting access controls, team and member permission management, original-media retention settings, two-factor authentication, IP access restrictions, and audit logs, and it holds ISO/IEC 27001 certification. Mobile apps are available for both iOS and Android. 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.
