Which fits you?

Start with your
next useful task.

Consider Logical if you want help with what is on your screen and want the data to stay on your machine. Consider Tallis if you want work done while the machine is closed, inside a private cell you can inspect and delete. Some founders will want a local copilot and a remote agent; they do not compete for the same hour.

This is our assessment of fit. We have not run a head-to-head performance or reliability test.

Try this before deciding

A useful test beats
a feature count.

Suggested evaluation steps, not a test we have performed.

  1. Work for an hour and read what it proposed and what it kept.
  2. Shut the laptop and see what continues.
  3. Ask each where its record of your work is stored.

Before you choose

Questions worth asking.

Local-only or private cell: which is more private?

Local-only keeps data on your device, which is as private as the device. A private cell keeps it on infrastructure you can inspect and delete, and lets work continue without the device. Logical publishes the first; Tallis is designed for the second. Pick by where you need the work to happen. [1] [2]

Tallis’s planned offer

Tallis is being built for a solo founder or operator: private ongoing context, included model access, recurring research, and controlled actions in connected accounts. Telegram and a web chat are the launch channels. Preview requires an exact preview and approval. Guardrails and Autopilot use the permissions you set; every mode retains pause and records of outcomes.

Access is currently by waitlist. These launch intentions are not a claim that every workflow is available today. Shared teams, an app-builder marketplace and unrestricted purchases are outside the initial offer. See Tallis.
