Brumo vs Pi — the calm AI showdown.
Pi was the gentle, thoughtful AI that people liked for just… talking. Brumo has the same calm but adds long-term memory and lives in iMessage. Here's how they compare.
Pi, built by Inflection AI, was often described as the kindest AI — a calm, non-salesy conversationalist. After Inflection's pivot in 2024, Pi's direction has shifted, but the original vibe is what many users were drawn to.
Brumo matches that warm tone (warm first, witty second) and adds two things Pi never had: long-term memory across weeks, and iMessage as the interface.
If you loved Pi's tone and want the same vibe with long memory and no app to open, Brumo is probably what you were hoping Pi would become.
Side-by-side
What made Pi special
Pi's calm, non-judgmental tone was genuinely different from other assistants. It was designed to be warm and slow, not fast and transactional. People used it as a sounding board more than a tool.
That tone is what Brumo also optimizes for. Our system prompt explicitly leans "warm before witty," and Brumo is built to hold a thought, not rush to answers.
What Pi didn't do
Pi famously had weak long-term memory — you'd have to re-establish context often. For one-off conversations that was fine; for a real companion it's a ceiling.
Brumo's entire model is built around long-memory retrieval. He remembers your sister's name, your goals, your moods, across weeks. That's the difference between a thoughtful chatbot and a companion.
When to pick which
- You liked Pi's tone and want it with memory.
- You want the AI in your messaging inbox, not another app.
- You want honest, friend-shaped replies that remember you.
- You just want a short, thoughtful chat without commitment.
- You prefer using a dedicated app.
- You don't want proactive messages at all.
Verdict
Brumo is basically what many Pi users wanted Pi to become — same calm tone, plus long memory, plus no app to install. Try him once by texting.
Quick questions
Is Pi still being actively developed?
Pi's direction changed after Inflection's team joined Microsoft. The product still exists but the roadmap is less clear than it was. Many former Pi users are actively looking for replacements.
Does Brumo have the same 'calm' tone Pi had?
Yes — that tone is a core design spec. Brumo is deliberately not a hyper-caffeinated productivity bot.
Is Brumo free like Pi was?
Yes, there's a free tier. Pro unlocks unlimited messages + long-term memory + proactive check-ins.
