Lifestack
What is Lifestack?
Lifestack is a productivity planner that builds your daily schedule around sleep, recovery, and focus instead of empty calendar blocks. It reads wearable and health signals, maps energy peaks and calm periods across your day, and drafts a schedule that places demanding work when you can actually focus.
Most calendar apps treat you like a task executor with unlimited stamina. Lifestack treats energy, meals, and rest as first-class inputs, overlaying focus and calm zones on your calendar so you see when deep work fits and when lighter tasks make sense. That body-first layer is the trade-off: it is narrower than a general project manager, but it connects health data to scheduling decisions most planners ignore.
The product suits professionals juggling meetings and deep work, ADHD users who need external structure around energy swings, and anyone syncing tasks from tools like Trello while trying to protect sleep and meal timing. Apps run on iPhone, Mac, Android, and Chrome, with a desktop Mac download and browser extension for calendar access.
GPT Workspace
What is GPT Workspace?
GPT Workspace is a productivity add-on that puts ChatGPT, Claude, and Gemini inside Google Docs, Sheets, Slides, Gmail, and Drive. You install a Chrome extension or Google Workspace add-on, connect Google via OAuth, and run prompts on the file or thread you already have open. It is built for teams that live in Workspace and want AI without copying text into a separate chat tab.
Standalone chatbots make you paste context every time. GPT Workspace reads the open doc, sheet, slide deck, inbox thread, or Drive file and writes formulas, drafts, summaries, and replies in place. Paid tiers add higher credit pools, advanced models like GPT-5.5 and Claude Opus, and team billing with shared usage.
Operations teams use the Sheets =GPT() formulas to classify rows and clean data at scale. Sales and support staff draft Gmail replies from full thread context. Marketers generate slide decks and rewrite docs in 18 supported interface languages without leaving Google's apps.
