Comparison

Brainspill vs Siri + Apple Reminders: what Siri still can’t do.

Disclosure: Brainspill is our app. Apple Reminders is genuinely excellent, and this page tells you when Siri alone is all you need.

They end in the same place

Brainspill is not a Reminders replacement. Tasks you capture in Brainspill sync into Apple Reminders — and things you add in Reminders show up in Brainspill. Same shared-family setup, same Apple Watch complications. The comparison is really about the capture step: what happens between a thought existing and a reminder existing.

Where Siri wins

• One task, hands busy. “Hey Siri, remind me to take the bins out at 7” while driving is unbeatable. Nothing to open, nothing to review.
• Zero cost, zero install. It’s already on every Apple device you own.
• Named-list commands. “Add milk to my Groceries list” files correctly — as long as you remember to say the list every time.

Where Siri stops — we ran the test

In July 2026, on current iOS, we said this to Siri: “Remind me — dentist Thursday at two, I still owe Jake that invoice tomorrow, need milk and coffee, and book something for mum’s birthday before the 20th.” Four thoughts, one breath. Here is what actually happened, across repeated attempts:

• One giant, undated reminder. The whole sentence landed as a single blob in the default list — no dates on anything, and “dentist at two” transcribed as “dentist tattoo.”
• Without the “remind me” prefix, nothing gets created at all. Siri decided the ramble was a text message and kept asking “To who?” — five attempts, five dead ends.
• A shorter two-item version lost data silently. “Remind me dentist at two, I still owe Jake that invoice tomorrow” produced exactly one reminder: “Dentist, today 2:00 PM.” The invoice vanished without a trace. This is the quiet failure that actually hurts — the first item lands, so you walk away assuming the rest did too.
• Siri kept cutting us off. In most attempts the listening window closed mid-sentence — a natural pause reads as “done talking.” Getting the full sentence through at all took several tries.

The same ramble in Brainspill produces: a calendar event (dentist, Thursday 14:00), a dated task (invoice Jake, tomorrow), two grocery items (milk, coffee), and a dated task (mum’s birthday gift, due the 19th). That’s the structural difference: Siri maps one utterance to one item — on a good day; Brainspill reads the whole stream and extracts every actionable thing in it, and it doesn’t hang up while you’re mid-thought.

Two more gaps worth knowing:

• The default-list pile-up. Anything you tell Siri without naming a list lands in the default list. A week later that list is a junk drawer you have to re-file by hand — the exact organizing work voice capture was supposed to remove.
• Composition under pressure. Siri asks you to pre-organize your speech into command form — and as the “To who?” loop shows, getting the form slightly wrong doesn’t degrade gracefully; it derails entirely. When thoughts are coming fast, that formatting step is precisely what fails.

And one thing Siri doesn’t try at all: the doing. Brainspill’s voice commands work after capture too — “what’s next?” hands you one task with a reason, “I’m stuck” breaks it into tiny first steps, “I just did X” marks it done from wherever you are.

The honest decision rule
