Airspeed, formerly known as Glyphic, is a sales conversation intelligence and revenue-team platform that records, transcribes, and analyzes calls and connects them with email and ticket history into a persistent memory of each customer account. It integrates with meeting platforms such as Zoom and Teams to capture conversations, then surfaces key themes, generates pre-call and post-call intelligence, and provides contextual answers about accounts grounded in actual interactions. For coaching, Airspeed identifies coachable moments with specific post-call scorecards, tracks metrics like talk-to-listen ratio against team benchmarks, delivers automated coaching plans before standups, and offers a practice simulator with buyer personas to build specific skills such as pricing-objection handling and champion building. It scores live calls during conversations and tracks rep improvement over time. On the workflow side, Airspeed auto-syncs data to Salesforce, HubSpot, and Outreach, works within Gmail, Outlook, and Slack, and uses agents that detect signals like champion changes or stalled deals to draft outreach for rep approval and maintain CRM hygiene. The company is based in London and New York and rebranded from Glyphic to Airspeed in 2026; it is a live, operating product. 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.
