Shortlist FlashRev when outbound teams running high-volume parallel-dialing campaigns matters most, and Slipbox when privacy-conscious professionals who cannot use cloud meeting bots matters most. Try them side by side on real calls before deciding — needs vary by team.

Privacy-first, bot-free AI meeting companion that captures system audio locally on Mac and Windows and turns it into transcripts, notes, and summaries.
FlashRev is the AI go-to-market product from FlashLabs (previously branded FlashIntel) that pairs outbound calling with conversation intelligence for B2B sales teams. Its AI parallel dialer places multiple outbound calls at once and connects reps instantly when a prospect answers, skipping unanswered calls and answering machines so sellers focus on live conversations. The platform records and tracks calls and analyzes each connected conversation in real time, automatically generating intent labels, converting transcripts into concise summaries, and identifying conversation sentiment at scale to support review and coaching. FlashRev positions itself as a broader revenue platform that combines prospecting data, omnichannel engagement across email, SMS, social, and calls, and AI sales-development automation, with the parallel dialer as one component of that suite. It integrates with common CRMs and sales-engagement tools such as Salesforce, HubSpot, Salesloft, and Outreach. The product is live and marketed to outbound and revenue teams; FlashLabs publicly announced an unlimited parallel-dialing capability and continues to develop the platform into 2025 and 2026. Pricing varies by plan. Check the official website for current pricing.

Slipbox is a privacy-first AI meeting companion built for individual professionals and teams who want to capture meetings without sending a bot into the call. Instead of joining a conference as a visible participant, Slipbox runs on your own machine and captures the device's system audio alongside your microphone, then transcribes the conversation on-device in real time. As the meeting progresses it can surface real-time insights and cues, and once the conversation ends it generates AI summaries using customizable templates, tagged notes, and searchable meeting records. Because the core transcription happens locally, audio does not need to leave the device, and the product uses a hybrid model in which optional cloud features can be turned on when needed; users can also bring their own LLM API key or point Slipbox at local models such as Ollama to keep data within their firewall. It works across common communication apps including Zoom, Microsoft Teams, Google Meet, Slack, FaceTime, WhatsApp, Signal, Telegram, Discord, and Webex, and integrates with note tools like Obsidian. Slipbox is available for macOS, Windows, and iPhone, and is suited to consultants, researchers, and privacy-conscious knowledge workers who want a personal meeting record without a meeting bot. Pricing varies by plan. Check the official website for current pricing.
