Build 887051446v4.72026-06-23 11:52:15
This update focuses on quality and stability:
• Sharper translations — more faithful wording, fewer dropped details and less over-editing
• Smoother performance and lower memory use
• Various bug fixes and refinements
Thanks for using Kanon AI — your feedback is always welcome!
Build 886098344v4.62026-06-03 22:56:20
v4.6 - Major Update
AI Tools Free Daily Trial
The 48 Pro tools are now open for free trial - 10 free uses per day, shared across all tools. Explore writing, business, travel, learning, creativity, lifestyle, office, and language tools across 8 categories. Hit the limit? It resets automatically at midnight local time.
Translation Quality Upgrade
Rewritten translation rules: the model now reads the whole passage first to grasp context, then translates faithfully - no over-polishing, no dropped phrases, no merging "redundant-looking" sentences. Closer to the original meaning.
Faster Launch
New "Preload AI Model at Launch" toggle. When off, the model loads only on first use, saving ~3-6 GB of memory and battery at launch. Significantly better experience on older devices (iPad mini 6, iPhone 12, etc.).
One-Tap Memory Release
A new "Unload AI Model" button on the Hub lets you release memory whenever you want. The model reloads automatically on next use.
All AI features run 100% on your device. No cloud, no data sent. Your conversations, creations, and privacy stay with you.
If you enjoy this update, please leave us a five-star review on the App Store so more people can discover Kanon AI
Build 885855410v4.52026-05-20 09:44:38
Kanon AI v4.5 — Small polish
[Stability]
- Fixed a rare crash that could occur when handling certain translation results
- Clearer alert when an AI model file fails to load (no more silent file removal)
[App Open Ad Fix]
- Fixed: App Open ads (the launch ad) sometimes didn't appear on iOS 13+ due to a scene-lifecycle issue
- Display interval tuned to 5 minutes (down from 30) to match actual app-switching patterns
[iOS Compliance]
- Added the "Allow Tracking" permission prompt as required by iOS guidelines — you decide whether to share tracking data with ad networks
- Declining tracking does NOT affect any feature; AI translation, chat, and tutor still run 100% on-device
Privacy unchanged: local inference, speech recognition, and draft storage all run on-device.
Build 885556716v4.42026-05-13 11:11:27
Kanon AI v4.4 — iPad Lands, AI Engine Tuned
[Full iPad Support] (NEW)
- iPad mini 6, iPad Air, iPad Pro — the whole lineup works now
- App is Universal — no more cramped iPhone-stretched-on-iPad look
- Sidebar menu redesigned for iPad layout; items no longer cut off
[AI Engine Major Tune-up]
- 4GB devices (iPad mini 6 / iPhone 13 / iPhone 13 mini / iPhone SE 3 / iPad) get a model upgrade: Qwen 2.5 1.5B → Qwen 3.5 2B
- AI Chat no longer falls into repetition loops on smaller models (systemic fix)
- Translation no longer leaks the model's English "thinking" stream (Qwen 3 native thinking disabled by default)
- Sampler fully re-tuned: Translation / Chat / Tutor / Tools each get their own optimised params
- Each model tier (small / medium / large) gets matching sampler settings — small models no longer punished by large-model prompts
[Advanced AI Settings] (NEW — Power user)
- Settings → Advanced AI Settings — tweak the sampler per task yourself
- 4 tasks × 4 parameters (Temperature / Top P / Top K / Repeat Penalty) = 16 knobs
- Live preview — modified values show a "(default)" indicator so you can see what was changed
- One-tap reset to the default matrix
[Translation Output Cleaner]
- Streaming UI no longer leaks the model's English "self-talk" reasoning
- Final result is clean too — no more "Sure!" "Here's the translation:" prefixes
- Script-based filter for: Traditional Chinese / Simplified Chinese / Japanese / Korean / Russian / Thai / Arabic / Hindi targets
[Model Management Fixes]
- When a model file fails to load, you now see a clear alert instead of the file vanishing silently
- Auto-detect common mistakes like "you downloaded the mmproj (vision projector) instead of the main model" — gives a specific hint
- AI Chat hides photo / mic buttons on models that don't support vision
[Privacy unchanged] All AI inference still runs 100% on-device. Nothing is uploaded.
Build 885395633v4.32026-05-08 14:38:57
Kanon AI v4.3 — Your Personal Assistant Goes Real, Your Companion Goes Personal
[Personal Assistant x iOS Calendar] (NEW)
- Tell the AI about meetings, birthdays, reminders, travel dates — they go straight into your iOS Calendar
- Get system notifications when the time arrives, even when the app is closed
- Deleting a note also removes the matching calendar event
[Companion: Build a Character from Your Photo] (NEW)
- Pick a photo from your album — the subject is lifted out automatically with a transparent background
- Group photos, side profiles, and tilted-head shots all work
- Your character blinks and breathes, just like the Live2D ones
- Fully on-device — your photos never leave the iPhone
[Major Translation Quality Boost]
- Japanese: kanji false friends, keigo levels, loanwords, sentence-final particles all handled with more care
- Korean: honorific levels, sentence-final endings, 우리 usage all properly matched
- Traditional Chinese output enforces Taiwan-style vocabulary (no more Mainland terms slipping in)
- Defaults to mirroring the source register; flip "Force Polite Tone" to override
[Language Tutor Correction System Rewrite]
- Three clear labels: "your version", "suggested", "common in casual speech"
- No more nitpicking on omitted subjects, casual contractions, or common slang
[Other Improvements]
- Auto-saved drafts across 6 features (Translator / Dictionary / Realtime Chat / AI Chat / Companion / Tutor)
- Mute toggle added to Language Tutor
- Various TTS and image-parsing stability fixes
Privacy unchanged: local inference, photo subject extraction, and draft storage all run on-device.
