Thoth vs Synopsule

UNDER THE SCRIBE'S SEAL. Thoth was built with one rule: your data stays yours. It's a native iPhone and iPad transcription and meeting assistant that processes audio locally. No cloud uploads, no hidden servers, no tracking. Optional cloud AI features use your own API keys and go directly to your chosen provider. We never see a byte. ON-DEVICE ANONYMIZATION Before a transcript reaches a cloud AI provider, Thoth detects names, places, emails, and phone numbers on your device and swaps them for tokens, restored locally after the response returns. You review what gets sent. Free for everyone. 100% OFFLINE TRANSCRIPTION Your private conversations don't belong on someone else's server. • Record from the microphone and transcribe entirely on device. • 99 languages with auto-detection. • Live Transcript: watch words appear in real time as you speak. • Neural speaker identification: tell apart up to 8 speakers, color-coded with our Egyptian-inspired palette. Fully on device. • Custom Vocabulary: add technical terms, acronyms, or names and the model favors them. • Re-transcribe any recording with a different model anytime. Free users can record up to 30 minutes per session. AI ASSISTANT Clean up, summarize, translate, and ask questions. Locally or via your own cloud provider. • Structured Summaries: overview, key points, decisions, participants, and action items with owners. • Smart Edit: Thoth flags the words it was unsure about so you can fix them in place, with an optional AI proofread. • Suggested Reminders: turn the action items from a meeting into real reminders you approve, in your Reminders app. • Improve Transcript and Improve Diarization with an AI pass. • AI Chat: ask anything about a recording and get answers grounded in the transcript, locally or with your own key. • One-click translation. Free users get 10 AI actions per month. Pro users get unlimited. VERIFIABLE PRIVATE AI For cloud AI, you can choose a privacy-first provider. One option runs models inside secure hardware enclaves with provable zero data retention, and Thoth verifies the attestation inside the app before each session. RUN AI ON DEVICE No internet, no API key, no problem. Use Apple Intelligence or download an on-device model sized to your iPhone. Summaries and answers never leave your hand. Counts toward your monthly AI limit (10 for Free, unlimited for Pro). BRING YOUR OWN KEY Plug in your own API keys for supported providers. Pick the exact model you want; the list updates live. Keys are stored in the iOS Keychain and sync to your other devices through iCloud Keychain. Requests go directly from your device to your provider. Cloud AI features are not available in all regions. BUILT FOR iPHONE & iPAD Control your recording from the Lock Screen and Dynamic Island. Per-recording notes. Search within any transcript. Export to PDF, Markdown, plain text, RTF, JSON, or free SRT and VTT subtitles, all generated locally. Send recordings to the Mac app over AirDrop or local WiFi, and your whole library syncs privately across your devices with iCloud. Airgapped by design. Homemade and private.

CALENDARS & MEETING REMINDERS Choose Apple Calendar calendars, including synced Google accounts. Set optional reminders, timing, sound and title privacy. Mute recurring series or notify only for invites with meeting links or dial-in details. Choose a meeting to use its title and invited-name suggestions. Recording starts only when you choose Record. Synopsule turns your iPhone and Apple Watch into a private transcription studio. Record any conversation, see a live transcript as you talk, and when you stop, see who said what - all on your device. Everything runs locally by default. Your audio never gets uploaded. RECORD ON iPHONE OR APPLE WATCH Tap record on iPhone for live transcription while you talk. Start from Apple Watch when your phone is not in hand, pause or resume, add markers, and send the saved recording to your paired iPhone for local processing. TRANSCRIBES LOCALLY WITH WHISPER OpenAI's open-source Whisper model runs entirely on your iPhone, optimized for Apple silicon. Choose a model size that fits your phone, from a fast compact model to a larger high-accuracy model. The download size is shown up front, and the model runs on-device once installed. LABELS AND RECOGNIZES SPEAKERS When a recording finishes, Synopsule figures out who said which line and assigns colored speaker labels on device. Name speakers and reuse saved voices across recordings. Voiceprints stay on your iPhone. NOTES AND FLAGS, ANCHORED IN TIME Jot notes while you record or read. Each note is pinned to the moment, so tap to seek straight back, and your notes can feed into the AI summary as context. Drop a flag on anything worth finding again and give it a label. OPTIONAL AI SUMMARIES, ON YOUR TERMS Press Summarize, pick a template, and get a structured, speaker-aware recap with action items and open follow-ups. Then choose where it runs: - Bring your own OpenAI, Anthropic, or Google Gemini key. Transcript text goes directly to that provider. - On an Apple Intelligence-capable iPhone, summarize on-device when available. - Or subscribe to Synopsule Pro and run summaries without managing your own key. Synopsule names the destination and asks consent before any text leaves your phone. Your audio is never sent anywhere - only transcript text, only when you ask. You can revoke consent any time in Settings. POWERFUL PLAYBACK AND EDITING Tap any line to jump to that moment in the audio. The transcript follows along as it plays. Fix a word or reassign a speaker inline whenever you like. SEARCH EVERYTHING Full-text search runs across every transcript. Filter by who spoke using speaker: queries to jump straight to the right moment. EXPORT ANYWHERE Export to Markdown, Word (.docx), plain text, SRT and VTT subtitles, or interactive HTML. You can also send a transcript straight into Obsidian or Apple Notes in one tap. Choose what to include: timestamps, speaker labels, grouping by speaker, and the AI summary. PRIVACY YOU CAN VERIFY - iPhone microphone audio is captured and transcribed on your iPhone. - Apple Watch recordings are stored locally on the Watch until transferred to your paired iPhone for on-device processing. - Transcripts live in protected app storage. Delete any recording whenever you want. - No ads and no cross-app tracking. Optional anonymous product analytics can be turned off in Settings.
