What's changed in Thunder Kitty.

We ship updates when we ship them. Sometimes fast, sometimes slow. This page is where we log what actually changed — new features, bug fixes, the occasional thing we had to walk back.

If you're running an older version, open Thunder Kitty → About → Check for Updates.

1.8.0

June 2, 2026

Google Calendar. Thunder Kitty now syncs with Google Calendar — pulling in your events, attendee names and emails, and firing meeting notifications, the same way macOS Calendar integration works. The difference: Google Calendar brings real display names, so your notes and transcripts use people’s actual names from the start.

YouTube import — paste a URL and Thunder Kitty downloads, transcribes, diarizes, and summarizes it. Part of the same import system as audio and video files.
Video file import — import now accepts .mp4 and .mov in addition to audio files.
Voice enrollment for imports — Thunder Kitty can now identify your voice in imported recordings. Live recordings don’t need this (the V2 audio stack separates your mic from system audio automatically); imports do.
Agenda sidebar — drag-and-drop reordering replaces up/down arrows. Cleaner hover states, smoother animations throughout.
Fixed echo cancellation reliability in no-headphones mode.
Fixed flickering in notes with many headings.
Settings UI and layout improvements.

1.7.0

May 26, 2026

Your voice and theirs, always separate. Thunder Kitty now captures your mic and system audio as two independent streams in real time — every session, regardless of headphone state. Previously, headphones were required to keep your voice cleanly separated from everyone else on the call; without them, echo made the separation unreliable. WebRTC’s AEC3 solves the underlying problem: system audio is used as an echo reference, and your mic feed is cleaned before it enters the pipeline. The result is deterministic speaker separation from the moment you start recording.

As a side effect: putting in or removing AirPods mid-recording now just works. And voice enrollment is gone — with real stream separation, it’s no longer needed.

Speaker–entity linking — link transcript speaker labels to people in your entity store, with type-ahead suggestions from attendees and known contacts. Mappings persist in the note.
1:1 auto-assign — Thunder Kitty automatically identifies the other speaker in one-on-one meetings, so summaries use the right name from the first pass.
MCP server updated with speaker–entity tools.

1.6.0

May 21, 2026

Import transcripts. Point Thunder Kitty at an audio file (WAV, MP3, M4A, AIFF) and it transcribes it in place. Already have a transcript? Import plain text, VTT, or SRT — or paste from the clipboard. Either way, it lands in the note like any other recording.

Join & Record — the Join button in the context panel now starts recording and arms auto-stop. New quick-record button in the sidebar for one-click note + record.
Document outline — collapsed heading indicators on the editor's left edge. Hover to see heading text, click to navigate.
Entities v2 — people and organizations are now tracked with stable identifiers across notes. Calendar attendee emails are used for cross-note matching.
Fixed unified mode (no-headphones) transcription stuttering.
Empty notes created by clicking calendar events without adding content are now automatically deleted.
Redesigned Support settings page; standardized borders, toggles, and text fields throughout.

1.5.0

May 18, 2026

Agenda Templates. Create templates for recurring meeting formats and load them into any meeting from the Agenda panel. No more rebuilding the same agenda from scratch.

Settings redesigned into focused sections.
Typography and layout refinements throughout the app.

1.4.0

May 15, 2026

Note attributes. Add people, organizations, and calendar events to any note using the new “+” menu. Autocomplete pulls from names already across your notes; hover any tag to remove it.

Recurring calendar events now correctly create a separate note for each occurrence.
Names with commas (e.g. “John Smith, Jr.”) are no longer split into separate entities.

1.3.2

May 13, 2026

Faster on-device AI — Meeting summaries and agenda recaps now generate up to 40% faster. When a note has an agenda, Thunder Kitty processes the transcript once and uses it for both — instead of starting over for each summary.

1.3.0

May 10, 2026

Claude Desktop. Thunder Kitty now works as an MCP server, giving Claude direct access to your meeting notes. Ask about past meetings, search transcripts, check what's being recorded right now, and track unresolved agenda items — all in natural language, no copy-pasting required.

To get started, open Thunder Kitty Settings and toggle on Claude Desktop located in Integrations, then restart Claude Desktop.

1.2.0

May 8, 2026

Per-item summaries — each agenda item gets its own AI summary after a recording, based on what was actually discussed. See exactly what moved on each topic without reading the full transcript.
API key management, redesigned — connect your own OpenAI, Anthropic, or Google key and choose from any model each provider offers. Keys are stored securely on your Mac.
Agenda items no longer disappear after clicking Done or adding a new item.
The error message when Apple Intelligence models are still downloading is now clearer.
Notes list sidebar no longer resets when navigating to and from Settings.
File sync is now activation-based — edits you make in Obsidian, iA Writer, or any other app are picked up the moment you switch back to Thunder Kitty.

1.1.0

May 6, 2026

Meeting Agenda. Walk into every meeting knowing exactly what you need to cover. Attach a structured agenda to any calendar-linked meeting, check off items as the conversation moves, and keep your talking points visible in a side panel while you record.

1.0.4

May 4, 2026

Phone calls and FaceTime audio are now transcribed end-to-end. The other person's audio comes through, not just yours.
System audio capture is more reliable across speakers, wired headphones, and AirPods.
Replaced the Screen Recording permission with a more focused System Audio Recording permission. New users will see a friendlier prompt; existing users will be asked once after updating.

1.0.3

May 2, 2026

Redesigned onboarding flow — friendlier, easier to navigate, and you can skip permissions and grant them later.
Notification and Calendar permission controls now live in Settings.
Reorganized the Settings sidebar so related items live together.

Editor performance improvements — typing and scrolling stay smooth in long notes.

Cmd+F search across all notes
Silence and filler word filtering in transcripts
Background post-processing — keep working while transcripts and summaries finish.
