Letterly is a multilingual AI speech-to-text app that turns dictated speech into polished notes, emails, summaries, and meeting transcripts across iOS, Android, Mac, Windows, and Web.
Allo is an AI-powered business phone system aimed at sales teams, support, and operations that records every call, transcribes it in real time, and syncs the recording, transcript, and an AI-generated summary to a CRM automatically. Positioned as mobile-native and quick to set up, it focuses on letting reps spend time selling rather than logging calls. Each conversation is recorded with consent-message compliance options, transcribed with speaker identification, and condensed into a shareable AI recap. Allo can then draft personalized follow-up emails and SMS based on what was discussed. The platform includes an AI receptionist for answering inbound calls, voicemail transcription, multi-tag organization of calls, and team collaboration features such as cascade ring and warm transfers. Managers can pull call recordings and AI transcripts to find coaching opportunities, while reporting dashboards surface connection rates, conversion tracking, funnels, and heatmaps. Allo integrates with CRMs including HubSpot, Salesforce, Pipedrive, Attio, and Apollo, and exposes an MCP endpoint to connect the phone system to AI assistants. It is a live, operating product as of 2025/2026. 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.
