Sivella vs Cozi: which shared household app fits your home?
Sivella turns a visible family schedule into visible responsibility. Named task owners, private free-busy calendar sharing, decisions, budgets and shared household context show everyone what needs to happen next.

Your household can see Friday's school event on a calendar and still leave one person carrying everything around it: sign the form, buy the supplies, arrange the ride and remember the deadline. Visibility is useful. Ownership is what makes the plan move.
Sivella connects the schedule to the work behind it. Tasks carry named owners, decisions retain their reasoning, the budget stays visible and calendar availability can be shared without exposing every appointment detail.
Every claim about Cozi below comes from Cozi's own site, read on 14 August 2026, with the URL in the body. Where something could not be verified from a first-party source, it is left out rather than guessed at.
Move from a visible schedule to visible ownership

When a shared calendar shows that the car needs servicing, Sivella records who owns the next step and whether it is complete. When a school event creates three follow-up tasks, each can go to the person responsible instead of forming another private checklist.
The household view brings those commitments together with decisions, kitchen context, money and availability. Both adults can open the same current state and act without asking one person to translate the calendar into work.
Turn every calendar item into a clear next action
Sivella shows open, active and completed tasks with their owners. That shared state replaces status-checking with a view everyone can trust. A person knows what they own; the rest of the household knows the work is moving.
Free-busy sharing adds the timing needed for coordination while keeping private event details private. Decision records preserve the reason behind a choice, and the household budget keeps its cost visible beside the plan.
Sivella carries no advertising on any plan. The household space stays focused on the people, work and context inside it. Cozi lists "No Ads" as a Cozi Gold benefit (https://www.cozi.com/cozi-gold/, read 14 August 2026).

"Not checked" means the detail was not confirmed from Cozi's first-party pages; it is not an assumption about the product.
Build a household that does not depend on reminders
Start with the event or recurring responsibility that creates the most follow- up. Add every next action to Sivella and give it an owner. The schedule now drives a visible workflow instead of creating more remembering for one person.
As tasks move, both members see the same progress. Add the decision, cost and availability context, and the next household plan starts from a complete record rather than another recap. Free includes two members, so this shared workflow can begin immediately.
Choose the Sivella plan that keeps enough context
What is included with Free? Two members, 45 days of context and Claude via four read-only MCP tools with 200 requests a month.
Can I keep using my existing calendar? Sivella shares availability rather than replacing your calendar app, so free-busy blocks can come from what you already use.
What is included with Helping Hand? Helping Hand costs $9 a month or ₹599 in India. It supports five members, keeps 14 months of context and includes full Claude access.
What is included with Right Hand? Right Hand costs $19 a month or ₹999 in India. It supports unlimited members and keeps 36 months of context.
Does Sivella train on household data? No. Nothing in your household is used to train models.
