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.

Letterly is a voice-to-text application that converts spoken words into clean, structured written text. Aimed at professionals, students, content creators, and anyone who prefers talking to typing, it lets users record speech directly in the app or dictate into other apps, then automatically transcribes the audio. Beyond raw transcription, Letterly applies AI rewriting so a single recording can become an email, a summary, a social post, a task list, a journal entry, or a meeting recap, using preset styles or custom instructions. It automatically detects and transcribes a wide range of languages and can handle mid-sentence language switching. For meetings and interviews, it offers speaker separation and can generate summaries from a recording. The app supports extended recordings, offline and screen-off dictation, quick-record widgets, and live sync across devices, including Apple Watch. It also integrates with external tools via Zapier and webhooks. Letterly states that user data is kept private and not used to train AI models. It runs on iOS, Android, Mac, Windows, and Web.
