The Pro Plan also includes access to GPT-5.2, GPT-5.5, and Gemini 3.5 Flash, plus unlimited note sync — notes normally stop syncing after 50 days of inactivity without it. iFlytek is currently offering anyone who registers a new Air 2 by October 31st, 2026 a free five year subscription to the Pro Plan. Cross-Device Editing: Full permission to view, manage, and edit notes across mobile apps, PC apps, and your e-ink device. Unlimited Sync Window : Bypasses the 50-day strict synchronization limit placed on free Starter Plan accounts.
