Turn voice notes into a private second brain you can talk to with Siri. Harbor is a completely free voice recorder, transcription app, and meeting note assistant built for iPhone. Record a thought, meeting, lecture, interview, or conversation. Harbor turns it into searchable transcripts, speaker-aware notes, summaries, decisions, and action items—without sending your content to a cloud AI. SIRI IS YOUR SECOND BRAIN Make your Harbor notes available to Siri, then ask questions across the transcripts and summaries you choose to index: • “What decisions have I made this month?” • “Summarize the most important themes in my notes.” • “Find unresolved questions across my voice notes.” You can also start recording hands-free with Siri, so ideas and conversations are easier to capture the moment they happen. COMPLETELY FREE Every Harbor feature is included. There are no subscriptions, recording credits, ads, accounts, trials, or paywalls. PRIVATE, ON-DEVICE INTELLIGENCE Apple Speech transcribes your recordings on device. On supported iPhones, Apple Foundation Models drafts titles, summaries, action items, transcript refinements, and speaker-name suggestions. Local Core ML models help separate speakers. Harbor has no developer-operated content server and does not send your recordings, transcripts, notes, or prompts to a cloud LLM. KNOW WHO SAID WHAT Follow provisional words and speaker labels while you record. Afterward, rename speakers, correct transcript sections, edit the summary, and play the original audio alongside your notes. SYNC WITH ICLOUD Choose an Apple Files folder for your library. Save it in iCloud Drive to keep your Harbor archive available through iCloud, or choose On My iPhone for local-only storage. Your selected Files provider controls storage and syncing. OWN YOUR ARCHIVE Harbor keeps the original audio and an authoritative recording.json file for every note. Export portable Markdown, RTF, or DOCX documents whenever you need them. Your edits remain the source of truth. CAPTURE WITHOUT FRICTION Start recording in Harbor, from the widget, or with Siri. Harbor saves audio first, so a conversation remains available even when an optional intelligence step needs another attempt. NO ACCOUNT. NO TRACKING. Harbor has no advertising, analytics, cross-app tracking, cloud LLM, or developer-operated account system. Audio, transcripts, summaries, speaker labels, titles, and edits stay on your iPhone or in the Apple Files location you choose. Some on-device features may download required model files the first time they are used. Siri and Apple Intelligence features depend on device, language, region, and system availability. Microphone access is required to record. Speech recognition, approximate location, calendar, and notification access are optional and used only for their related features. Requires iOS 27 or later.
