Context

Why people look past ChatGPT

ChatGPT is the product everyone measures assistants against, and for chat, research and writing it deserves that. Agent mode and deep research turned it from a text box into something that goes away and comes back with work done, connectors reach into Drive and mail, and at $8 for Go the entry price is the lowest here. As a general assistant it is the safest default on the list.

It is still a chat product with agents attached. Everything runs on OpenAI models inside OpenAI's sandbox, and each capability carries its own quota, so you run out of deep research while your message allowance sits untouched. Agent mode can keep cookies between runs and schedule recurring tasks, but it does so inside OpenAI's environment: it never opens a terminal on your machine, never picks up a CLI tool you installed, and never uses the Chrome profile your real sessions live in.

01
A wall per feature

Messages, deep research, agent runs and images each have a separate cap. You hit one and the rest of the plan cannot cover for it.

02
Its sandbox, not your systems

Agent mode browses in OpenAI's environment and keeps its own sessions there. It is still not a shell on your PC, not your Chrome profile, and not your repo.

03
One vendor, no second opinion

Every answer comes from OpenAI models. There is no way to have Claude or Gemini review the output before it ships.

How we scored

Each tool gets 0 to 5 on six dimensions: model freedom, long-running work, beyond code, openness, team & permissions, cost predictability. The sum is the score in the table. Facts (pricing, interface, models, licence) were checked against each vendor's public pages on 2026-09-17.

The ratings are ours, and we are on the list, so weigh them accordingly. Every fact behind a rating is checkable, and where a competitor is the better pick for a job we say so in its card.

Our take
Keep ChatGPT for what it is best at: everyday questions, writing and research. Use TODO for AI when the output has to land somewhere real, on your machine, in your browser, in your repo, or in your ad account, on whichever model is right for the step, against one pooled budget instead of a dozen separate caps.
