🪟 Kaikou for Windows · Voice input for people who find typing hard

Speak, and it's written — data never leaves the machine

Offline, on-device recognition: finish a sentence and the text lands at your cursor. Meetings produce minutes automatically — dual-track audio, clear speaker separation, minutes and to-dos organized together. The app contains no AI credits: AI runs on your own API key, while every offline feature costs nothing.

Windows 10 1809+ / 11 (64-bit) · Per-user install, no admin rights · v1.3.7 feature-parity with macOS 1.1.0

The Interface

What it looks like on Windows

Lives in the tray; hold Right Alt to speak. A four-row candidate panel; meeting notes written while the meeting happens.

Scene 01 / 3

Candidate panel · Four rows to pick from

Everyday typing

Kaikou lives in the tray; hold Right Alt and speak. When you finish, four candidate rows appear: original, AI-polished, terminology, and Prompt — arrow keys to choose, number keys for direct pick, Enter to insert.

Recognition runs offline on-device; candidates appear the moment you stop — no internet needed.

Meetings

Paragraph by paragraph with timestamps and speakers; remote participants tagged separately. Mark highlights, to-dos, and decisions on any segment — after the meeting, generate a four-part minute in one click.

Export minutes to Word (.docx) / RTF / Markdown / plain text / email draft.

Where the Windows edition shines

When the meeting ends, the minutes are already written

More than "speech to text": a complete on-device pipeline — capture, segmentation, speaker ID, refinement, minutes, to-dos, export.

✍️

Text as you talk

Local, offline recognition that never breaks the meeting's flow; each sentence lands as it's finished — no waiting until the end.

🎧

Both audio tracks captured

Room (microphone) + online (system audio) recorded at once; remote speakers auto-tagged "Remote".

👥

Knows who's speaking

On-device voice clustering separates speakers automatically; rename them ("Engineer Zhang", "Director Li") and exports update accordingly.

🔍

Post-meeting Whisper refinement

When audio was recorded, Whisper re-transcribes the entire session offline in the background for a more complete, fluent transcript. The live draft stays untouched; failures stay silent.

📋

One click to finished minutes

Four-part minutes (topics / conclusions / to-dos / open items), exportable as Markdown, plain text, or an email draft; Save As supports Word (.docx) and RTF.

✅

To-dos follow through

Tasks mentioned in meetings land in the ledger automatically; before the next meeting, unfinished items resurface on their own.

🔒

Everything stays on your machine

Meeting notes, to-dos, and exports all live in %APPDATA%\Kaikou; uninstalling never deletes them.

Pricing, plainly

Windows: the app is free, AI uses your own key

We sell no bundles, no credits, no tiers. The only thing you'll ever pay is what your AI provider bills you, by usage.

Why we price it this way: dictation, meeting notes, to-dos, and exports are local capabilities — they cost nobody anything, so they're free forever. AI polishing / rewriting / translation calls large models, and that cost is paid by you directly to the provider (DeepSeek, Qwen, Zhipu, and others). We never collect it, never mark it up, and never lock you to any provider. Add your own key under Settings → Product Mode.

The macOS edition uses App Store subscriptions (basic free + Pro/Ultra tiers) — a different business model. See macOS pricing here.
Who it's for

Built for people who find typing hard

Speak → text appears at your cursor, without typing a single character. Dictation, meeting notes, and exports need no key at all.

🤝

People with hand conditions

Rheumatoid arthritis, carpal tunnel, Parkinson's tremor… when hands won't cooperate, your voice still replies, writes, and emails.

✓ Text inserts right at the cursor — no manual pasting

👨‍👩‍👧

Parents and grandparents who never learned to type

No pinyin, slow typing, voice messages only. Let them speak what they want to say — and send it as real text.

✓ Say it, pick a candidate, and it's sent

💪

Recovery and care situations

One-handed after a stroke, or bedridden and cared for — your voice keeps family conversations going.

✓ Dictation and meeting notes free forever, no key needed

🗣️

Heavy meeting-goers

Online and in-room meetings both need notes, minutes, and follow-ups — the Windows edition does most of that for you.

✓ Dual-track audio + speakers + minutes + task ledger

💼

Productivity-minded professionals

Proposals, replies, daily reports — speaking beats typing. AI polishing turns spoken language into written language, using the key you bought yourself.

✓ BYOK — providers bill you directly, by usage

🔒

Privacy-conscious users

Recognition runs locally; audio never uploads. Meeting records and history stay on your machine — check exactly how much space they use, anytime.

✓ Recognition engine runs 100% locally

Install & first-run

Three steps and you're talking

Per-user install: no admin rights, nothing written to system folders.

System requirementsWindows 10 1809 or later / Windows 11 (64-bit)
InstallationDouble-click the installer → Next → Done. Installs to %LOCALAPPDATA%\Programs\Kaikou
First launch4-step guide: permissions → microphone test → download the offline recognition model (~239MB); skippable too
What if I skip the model?Dictation and meeting notes won't work — Windows' built-in speech recognition doesn't run under .NET 8, so the offline model is a prerequisite
AI featuresAdd your own API key under Settings → Product Mode (optional; only affects AI polish/rewrite/translate)
UninstallUninstall normally from the Control Panel; your settings, history, and meeting notes are preserved (to wipe them, delete %APPDATA%\Kaikou manually)
A known promptThe installer is currently unsigned, so SmartScreen shows "Unknown publisher" — click "More info → Run anyway" to continue
