Lifestack vs 2 Slash

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.

2Slash is a Chrome extension that runs an AI writing assistant on any webpage without typing prompts yourself. You pick actions from a built-in prompt library, and the extension generates text, images, or speech in context where you are already working.

Browser chat tools expect you to craft prompts for every task. 2Slash preloads expert-written prompts for text, image, and video workflows so you select an action instead of engineering wording. The library includes 50+ free prompts on the free tier and 100+ expert prompts on paid plans.

Free accounts on 2slash.ai include 3,000 words per month, 5 generated images, and 1,000 text-to-speech words across models like GPT-4o, Gemini 1.5 Pro, Claude 3.5, and Llama 3 with no OpenAI API key required. Premium at $14 per month raises limits to 20,000 words, 25 images, and 10,000 TTS words plus unlimited prompt requests.

2Slash targets marketers, support teams, and operators who want generative AI inside Gmail, docs, and social sites without switching tabs. Enterprise and prompt-on-demand services are listed separately on 2slash.ai for teams that need custom prompt packs.
