Dayflow.

Dayflow

Dayflow is an open-source automatic work journal for macOS that transforms how knowledge workers understand and reflect on their daily productivity. By intelligently analyzing your screen activity using AI, it creates a detailed, contextual timeline of your work—eliminating the need for manual time tracking and giving you an honest, data-driven view of where your day actually goes.

Product Highlights

• Automatic Activity Tracking: Captures your screen at 1 frame per second and uses AI to analyze your work every 15 minutes, distinguishing meaningful tasks from distractions without any manual input.
• Privacy-First Architecture: Stores all screenshots and data locally on your Mac, with optional local AI processing (Ollama/LM Studio) ensuring nothing ever leaves your device.
• Contextual Intelligence: Goes beyond simple app logging to understand what you're actually doing—differentiating "researching on YouTube" from "watching cat videos" for accurate, narrative summaries.
• Open Source Transparency: Licensed under MIT, fully auditable code that you can inspect, modify, and build yourself, ensuring complete trust and data ownership.
• Lightweight Performance: Runs efficiently using only ~100MB RAM and under 1% CPU, designed to never slow down your workflow.
• Flexible AI Options: Choose between free local models, Gemini's free tier, or premium cloud providers (ChatGPT/Claude) with the ability to switch anytime based on your accuracy and privacy needs.

Use Cases

• Developer Workflow Optimization: Automatically document coding sessions, API research, and debugging work to identify productivity patterns and eliminate time-wasting context switches.
• Freelancer Time Accountability: Generate detailed client reports and personal invoices backed by visual evidence of actual work completed, removing guesswork from billing.
• Remote Work Self-Management: Maintain awareness of your daily progress and focus when working independently, preventing the "where did my day go" phenomenon common in distributed teams.
• Career Reflection and Growth: Build a long-term archive of your professional development to review achievements, identify skill growth areas, and prepare for performance reviews.

Target Audience

Dayflow is built for developers, freelancers, designers, and knowledge workers who value data ownership and want an honest, automated record of their professional time—particularly those at startups and tech companies who appreciate transparent, open-source tools that respect their privacy.
