Todoist Ramble voice AI — what it still can't do

Todoist's Ramble feature converts speech into structured tasks using Gemini 2.5. Here's what voice-to-task AI does well and where cross-channel habit agents begin.

Todoist shipped Ramble in January 2026 — a voice-to-task feature powered by Google Gemini 2.5 Flash Live that converts natural speech into structured tasks: project assignment, due date, duration, and priority extracted in real time. It supports 38 languages, streams audio without a tap-to-record delay, and is available across iOS, Android, macOS, Windows, and web. Free users get 10 sessions per month; Pro and Business users get unlimited.

For people who hate typing tasks, it is a meaningful quality-of-life upgrade.

What Ramble does well

The AI parsing layer handles ambiguous speech gracefully. "Remind me to call my accountant Tuesday before lunch" becomes a task with the right date and time — not just a text string dumped into your inbox. "Add three hours for the proposal to next Thursday" creates a time-boxed block, not a vague to-do.

Voice capture has a clear use case: thoughts that arrive when your hands are busy. Driving, walking, cooking, mid-workout. Ramble lowers the friction for those moments below what Siri shortcuts or manual quick-add could manage.

What it doesn't change

Ramble is capture, not execution. The gap between knowing you need to do something and actually doing it consistently is where most productivity systems break down — and Ramble doesn't touch that layer.

Specifically:

  • No proactive reminders across channels — Todoist still notifies you via app push. It doesn't reach you in Telegram or Slack.
  • No behavioral memory — Todoist doesn't adapt based on what you missed last week. It shows you the overdue task; it doesn't ask why it happened or adjust the cadence.
  • No habit model — recurring tasks and habits are different abstractions. Tasks have due dates; habits have streaks, exceptions, and tolerance windows that recurring Todoist tasks don't encode cleanly.
  • Single surface — Ramble adds tasks to Todoist. It doesn't feed a behavior engine that runs across your channels.

If your bottleneck is capturing tasks, Ramble solves that. If your bottleneck is follow-through and consistency over time, the execution layer is still a separate problem.

How this plays alongside Buffy

The two tools aren't competitors for the same function. A practical split that works:

  • Todoist + Ramble for work tasks — projects, deadlines, meeting prep, deliverables where structure and project assignment matter.
  • Buffy for personal habits and routines — the behaviors where consistency over weeks matters more than inbox management.

Both can run simultaneously without conflict. Todoist owns your task inbox. Buffy owns your behavioral follow-through across Telegram, ChatGPT, and Slack.

The voice input gap on the behavior agent side is real — most users still type habit check-ins or use short commands. That may narrow as voice-native interactions mature in chat platforms.
