Chorus vs Pi by Inflection AI
Pi ("personal intelligence") is Inflection AI's conversational companion, designed around emotional intelligence: a patient, warm chatbot you talk to about your day, decisions, feelings, and ideas via text or voice. As of July 2026 it is still live at pi.ai and in iOS/Android apps, still completely free, and still receiving app updates — but it is a side product for Inflection, which pivoted to enterprise AI after Microsoft hired away its founders and most of its team in March 2024.
Chorus is a platform for hiring AI employees — autonomous AI agents that each run on their own always-on computer, connect to 70+ tools, and handle real work end to end. Here’s how the two compare, honestly.
At a glance
| Comparison dimension | Chorus | Pi by Inflection AI |
|---|---|---|
| Always-on computer | Every agent runs on its own dedicated always-on machine (4 vCPU / 8 GB) with a real browser — it keeps working when your laptop is closed. | No — Pi is a hosted chat companion with no per-user machine or browser; nothing runs for you between conversations. |
| Tool integrations | 70+ integrations out of the box — Gmail, Slack, Notion, GitHub, Linear, Stripe, and more. The agent handles the auth. | None with third-party apps (no Gmail, Slack, calendar, etc.); built-in capabilities are limited to real-time web search, reminders/checklists, shareable plans, and a Daily Brief. |
| Messaging channels | Web chat, iMessage/SMS, Slack, WhatsApp, and Telegram — and it messages you proactively when work is done. | Web (pi.ai) plus iOS and Android apps with text and voice; WhatsApp, Facebook Messenger, SMS, and other messaging-app channels were discontinued in 2024. |
| Persistent memory | Persistent memory and files live on the agent's own disk, so it remembers last week's work. | Remembers past conversations and recalls them across sessions, adapting to your style; no user-managed memory store or file system. |
| Background automations | Scheduled jobs (crons) and background automations are built in — agents work while you're away. | Reminders, checklists, and a Daily Brief only; no scheduled jobs, background task execution, or proactive work. |
| Pricing | Free plan to start (no card). Pro $20/mo for one always-on agent; Max $200/mo; extra agents $50/mo. | Free for everyone with no paid tier or in-app purchases; Inflection announced caps for extremely heavy free usage in 2024 (no published limit; normal use is effectively unlimited); enterprise API/model licensing is custom-priced. |
Where Pi by Inflection AI shines
- A genuinely distinctive conversational style: warm, patient, and emotionally attuned — Pi remains one of the better AI products for talking through feelings, decisions, and everyday life rather than issuing commands.
- Completely free with no card, no subscription, and no feature paywall; the App Store listing shows no in-app purchases at all.
- Polished voice mode that works well for hands-free conversation on walks and commutes, with voice and notification improvements shipping as recently as mid-2026.
- Remembers past conversations and picks up where you left off, with reminders, checklists, shareable plans, real-time web search, and a Daily Brief built in.
- Still actively maintained in 2026 — a redesigned app with a new logo shipped in the weeks before July 2026, and Inflection's status page shows 100% uptime for pi.ai.
Where it falls short
- Pi converses but does not act: it has no integrations with Gmail, Slack, calendars, or other external apps, cannot log into websites, and cannot execute tasks on your behalf beyond reminders and built-in web search.
- Nothing runs while you are away — there is no background work or scheduled jobs beyond simple reminders and a Daily Brief, and Pi never has its own computer or browser.
- Development has been deprioritized since the March 2024 Microsoft reverse-acquihire; Inflection's roughly 70-person team focuses on enterprise models, so Pi evolves slowly compared with frontier assistants.
- Channels have shrunk rather than grown: Inflection ended Pi's WhatsApp, Facebook Messenger, SMS, and other messaging-app support in 2024, leaving only the website and mobile apps.
- It runs only on Inflection's own models — no choice of Claude, GPT, Gemini, or other frontier models — and there is no paid tier to buy higher limits or priority if you ever hit the free-usage caps Inflection reserves for extreme power users.
Choose Pi by Inflection AI if…
- You want a free, emotionally supportive companion to think out loud with — processing a hard day, rehearsing a conversation, working through a decision — not an agent that does work for you.
- You value natural voice conversation for casual daily chat and want it at zero cost with zero setup and no credit card.
- You want a calm, non-technical AI with no integrations, configuration, or permissions to manage — just open the app and talk.
- You are specifically drawn to Pi's high-EQ personality, which most task-oriented assistants and agent platforms do not replicate.
Choose Chorus if…
- You need an AI that executes work in real tools — sending email, updating Notion, triaging GitHub or Linear, running a browser to use websites — rather than talking about it.
- You want work to continue while you are away: scheduled jobs, automations, and an agent that messages you proactively when something is done.
- You want to reach your AI over iMessage/SMS, WhatsApp, Telegram, or Slack — channels Pi discontinued in 2024.
- You want frontier model choice (Claude Opus 4.8/Sonnet 5, GPT-5.6, Grok 4.5, Gemini 3.1 Pro) and a dedicated always-on cloud computer per agent.
Common questions
Is Pi AI still available in 2026?
Yes. Pi is live at pi.ai and in the iOS and Android apps, Inflection's status page shows full uptime through mid-2026, and the mobile app received a redesign with a new logo in the weeks before July 2026. That said, Inflection's business focus is now enterprise AI, so Pi develops more slowly than it did before the 2024 Microsoft deal.
Is Pi AI free, and is there a paid plan?
Pi is completely free with no subscription or in-app purchases, and there is no paid consumer tier at all. Inflection makes money from custom enterprise licensing of its models; in 2024 it announced usage caps aimed only at extreme power users, and everyday use remains effectively unlimited with no published message limit.
Is Pi better than Chorus?
They are different categories. Pi is a free, emotionally intelligent companion for supportive text and voice conversation — it does not connect to your apps or do work for you. Chorus is a platform for hiring autonomous AI agents that each run on their own always-on cloud computer, integrate with 70+ tools, and execute scheduled and background work; if you want conversation and emotional support choose Pi, and if you want work done choose Chorus.
