Use browser agents for login-heavy web chores

A poster put six browser agents through routine online work and found Manus useful but too costly and still prone to bot checks.

What they did
They ran a side-by-side test of six agents on common web jobs, including filling out applications, signing into accounts to pull information, acting on their behalf in posts, working through assignments, and searching for API or troubleshooting details. The group included ChatGPT agent, Manus, Perplexity Computer, Perplexity Comet, plus two local Playwright-based setups. They pointed out that Comet worked within their own browser, while the local setups struggled even with simple requests.
How it went
Comet came out as the most practical choice overall. Manus could handle many tasks, but it was expensive for regular use and still got caught by bot detection; ChatGPT agent did the poorest, and the two local model setups were not ready for production. They added that most of their examples involved multi-step actions inside authenticated sessions.
Tips
Tools that launch a new browser session can run into login and anti-bot problems. Ask the agent to stop before any submission, payment, deletion, or publishing step.

Try it yourself with Manus

Please handle this browser task for me: [describe the job application, login, data retrieval, or posting task]. Use the browser session I already have open if you can, and if a site asks for a login or blocks you with anti-bot checks, stop and report it rather than retrying endlessly. Limit the work to [number] items, then summarize what you completed in a short table. Before you submit, send, pay, delete, or publish anything, pause and ask me to approve it.

Fill in the [brackets]. Agents can make mistakes, so review anything before it is sent, paid or deleted.
