1Lens is a metacognition practice and reflection tool. Choose a mental model you want to work on, record your decisions and actions in everyday situations, and look back on what changed. • Practice mental models: Start with built-in models such as First Principles, Win-Win Thinking, and Growth Mindset, or create your own. Keep up to three models active to stay focused. • Record wins and misses: Note what went well or where you fell short. Make a specific “If…then…” plan for your next attempt. • Reflect with voice: Record your thoughts and, when supported by the device, transcribe them with Apple’s system speech recognition. Recordings, transcripts, and practice entries stay on your device. • Review your progress: Browse recent daily entries and reflection history, and use your practice streak to notice your rhythm. • Make it yours: Edit or archive models, then reactivate them from the full list whenever you are ready. Optional reminders can help you build a routine. Take a moment to notice how you think, then choose what to do next. Microphone access is used to record voice reflections. Speech recognition access is used for on-device transcription. Recording starts only when you choose to begin.

On selected websites, the Safari extension supports social posts, discussions, articles, repositories, paper pages, podcast show notes, and available video text. Support depends on the site, page type, and accessible content. Video summaries use only the current video's available transcript, subtitles, timeline text, or chapters.
