Pensieve vs ScreenStack Screenshot Manager

Pensieve is a voice-first thought-capture tool. Named after the Pensieve from Harry Potter — pour your thoughts in and revisit them later. The best way to take notes is to not write notes at all. Just speak. [Key Features] • Record on the Go One tap, no typing. While walking, driving, or whenever inspiration strikes — just say a sentence. • Offline Speech Recognition Built-in SenseVoice model supports Chinese, English, Japanese, Korean and Cantonese. No network needed. Recordings never leave your device. • AI Auto-Organize (Optional) Auto-generated summaries and tags. Tap "Organize" and your scattered thoughts become structured text. AI Organize is optional — you can bring your own provider (DeepSeek, Alibaba DashScope, Groq, etc.) and a clear consent dialog appears the first time. • Append Add follow-up recordings to the same thought. Fragmented thinking from different moments comes together as a complete idea. • One-Tap Reminders Set reminders on important notes. The system pushes a notification at the scheduled time, tap to open the note directly. • iCloud Backup Recordings and notes auto-sync to iCloud. Change phones without losing anything. Completely optional, off by default. • Privacy First No account required. Zero data collection. No ads, no trackers. We have no servers — all data is fully under your control. Supported languages: Simplified Chinese, Traditional Chinese, English, Japanese, Korean.

ScreenStack is an AI-powered screenshot manager that helps you get screenshots in, find what matters, use the information inside them, and clean up with confidence. Local-first by design, with optional AI enhancement. SHARE FROM ANYWHERE Use the system share sheet in any app to send a screenshot or photo straight into ScreenStack—verified working from Photos, WeChat, and similar sources. AI SORTING Open the app to a visual screenshot wall. New imports are routed into Important, Saved, Quick, or To Review. Your rules come first; uncertain items stay honest instead of being forced into the wrong category. Correct a suggestion once and ScreenStack remembers. INSTANT OCR SEARCH On-device OCR turns screenshot text into searchable information. Find verification codes, order numbers, Wi-Fi passwords, amounts, and tracking numbers in about half a second—and copy the field you need, not just the image. OPTIONAL AI, YOUR KEY Connect your own API key from 17+ model providers for more detailed classification and extraction. Your provider, model, and rules stay under your control. Core features work without a key. SAFE CLEANUP Review extracted fields before deleting. Soft-deleted screenshots go to a trash folder, while saved credentials and favorites can keep an original backup. SAFE BACKUP & RESTORE Export a free, offline backup that preserves original image copies, OCR text, extracted fields, notes, tags, and organization status. Restoring verifies the file, then merges it non-destructively—nothing is lost when you switch devices or reinstall. SCREENSTACK PRO Smart Cleanup groups visually similar screenshots and identifies expired credentials. Credential Wallet adds expiry reminders and batch CSV export. One-time purchase, no subscription. PRIVACY FIRST OCR, search, and organization run on your device. Original screenshots never leave it. Only when you enable AI and provide your own key are extracted words sent to the provider you choose. Import, organize, search, and basic cleanup are free forever.
