Stop planning your day.
Start committing to it.
Tendi manages your to-dos, habits, and calendar in one place — then its AI Planner books real time for each one, so nothing just dies on a list.
You don't have a to-do list problem. You have a time problem.
A list tells you what to do. It never tells you when — so it never happens.
Tendi's fix is simple: everything you commit to gets a real time on your calendar.
An AI Planner that does the scheduling math for you
Pick a strategy, set your guardrails — from there, Tendi decides exactly where every task and habit goes.
You choose what comes first
Earliest deadline first, priority first, or balanced across your week — you decide the order.
Never double-books you
Pick which calendars count as busy time, and it'll never double-book you against them.
Habits included, not an afterthought
Recurring habits get scheduled alongside deadline-driven tasks, with buffers between every block.
Knows what to bump, and when
It weighs each task against the list it belongs to and what's already on your calendar — moving priorities up when your week is clear, and back when it's not.
From list to committed schedule in three steps
Capture everything
Add todos and habits the moment they come to mind. Set duration, priority, and how flexible each one is.
AI Planner finds the time
It scans open blocks on your calendar, respects existing events, and slots in each item — with buffers so nothing collides.
Review, tweak, commit
See the full plan before it goes live. Nudge anything, then confirm — it's on your calendar as protected time.
What changes once it's all on the calendar
Your list actually gets shorter
Tasks don't just sit there — each one has a real time, so it either gets done or you consciously move it, instead of scrolling past it for the tenth day.
Habits survive busy weeks
Because your workout or reading time has a protected slot, it doesn't get quietly skipped the moment your calendar fills up.
You know your real capacity
Before you say yes to one more thing, you can see exactly what's already spoken for — so your yes doesn't wreck your week.
One plan, on every device you use
Plan on your Mac, review on the web, and keep your tasks, habits, and schedule in sync. iOS is coming soon for capture and check-ins on the go.

"Tom did not know how to use a computer for the longest time. I think he only became a software engineer to spite me, and I can't believe he actually made his own app."
"Tom owes me 10% because I wrote his college application essay. You're welcome, Tendi."
"I don't actually use this app, but Tom said he needed an endorsement. He is a god-tier Rust dev, though, so you should probably try it."
Questions, answered
Does Tendi replace my calendar app?＋
No — Tendi syncs with Apple Calendar (Google Calendar support is coming soon), so anything it schedules shows up right alongside your existing events.
What if the AI schedules something at a bad time?＋
Nothing goes on your calendar without your review. You'll see the full proposed plan first — drag, remove, or approve each block before it's confirmed.
Can I use Tendi without the AI Planner?＋
Yes. Todos, habits, and the calendar are free and work great on their own — the AI Planner is there on Pro whenever you want it to do the scheduling for you.
Which calendars does it support?＋
Apple Calendar today, with Google Calendar support coming soon.
Is my data private?＋
Your tasks and habits sync securely across your Mac and the web so they're always up to date, with iOS support coming soon. We never sell your data, and you can disconnect any calendar at any time.
