I’m one of the founders of DailyStack.
Like many of you, my workday used to start with a "tab crawl." I’d open Gmail, then Outlook for the corporate stuff, then scan Todoist, check the Linear board for dev tickets, and finally peek at Asana for the marketing syncs. By the time I actually knew what my day looked like, I’d already context-switched five times and lost the "deep work" window of my morning.
We built DailyStack to solve this. It’s a single, high-signal brief that aggregates your day before you dive into the noise.
How it works
We currently support Gmail, Google Calendar, Outlook, Todoist, Linear, and Asana. Instead of just giving you a long list of notifications, we pull the "delta" from the last 24 hours:
Email: Highlights threads that actually need a reply vs. newsletters.
Tasks: Correlates what you finished yesterday in Linear/Asana with what’s actually due today in Todoist.
Calendar: A unified view across Google and Outlook so you don't double-book your life.
The "No-Storage" Architecture
We know that asking for access to your email and task managers is a massive request. We decided early on to build this with a zero-persistence mindset for your private content:
Ephemeral Processing: We don't save your email bodies or task descriptions to a database.
On-the-go Summaries: When you request your brief, we fetch the data via OAuth, process the summary in memory, and serve it. We don't "store and mine" your data to build a profile or train models.
Token Security: We only store the encrypted refresh tokens needed to communicate with the APIs.
Why we’re doing this
There have been a hundred "all-in-one" inboxes that failed because they tried to replace the tools themselves. We aren't trying to be a new email client or a new task manager. We just want to be the 5-minute summary you read before you open those tools.
We’d love your brutal feedback:
The Trust Gap: If you see a summary of a Linear ticket or a Gmail thread, do you feel an immediate urge to go verify the "real" version? How can we make the summary feel authoritative enough to trust?
Missing Pieces: What is the one tool that, if missing, makes an aggregator like this useless for you? (We're looking at GitHub and Notion next).
The Workflow: Does a "Morning Brief" actually fit your routine, or do you prefer to live in the raw feeds all day?
We’re pre-revenue and still figuring out the best way to make this indispensable. I’ll be in the comments all day to talk about the ETL challenges, API rate-limiting nightmares, or anything else.
Thanks!
