Side by side on speed, price and privacy. Claude extensions read pages 2-4x faster; ChatGPT's official one cannot read your page at all.

Haiku $0.10/$0.50, Sonnet $2/$10, Opus $4/$20 per million tokens. Which to pick for extraction, chat and hard reasoning, with real per-task costs.

Yes, but the free tier caps Sonnet 5.5 at roughly 20-30 messages a day. Here are the exact limits, plus 5 ways to reach Opus 5.5 without $20/mo.

Five working routes to Claude with no Pro plan, including a free way to try Haiku in Chrome. What each one costs, what it caps, and who it suits.

Open a side panel that reads the active tab and type "Summarize this page in 5 bullets". The prompts that work on articles and docs, and where it fails.

Point an AI at a job application, CRM record or checkout and it fills the fields. How it works, where it breaks, and the prompts to use.

At what monthly usage does a $20 subscription beat paying per message? We ran the numbers for light, normal and heavy users. Full breakdown.

Every AI extension routes your page somewhere. Here is what actually leaves your machine in each architecture, and how to verify the claims.

The permission requests, policy phrases and ownership changes that mean an extension is monetising you. Audit any extension in five minutes.

Two ways to give an AI a browser. One spins up a headless instance, one drives the tab you are in. Architecture, speed and when each wins.

Snapshot, click, fill, navigate, wait, switch tabs: what each of Prophet's 19 browser tools does, and why reading the page first decides reliability.

We ran the same market research project by hand and with a browser agent. Same output, 15 minutes instead of four hours. Here is the method.

Unused capacity, lock-in, and the data you cannot export. What a $20/mo AI plan really costs in a light month, and the usage-based option.

Pull structured detail off a LinkedIn profile, draft the outreach and score the CV without tab-switching. Recruiter prompts that work today.

Say what you want and the browser does it. Why plain-English automation is replacing brittle Selenium scripts, and where it still falls over.

Both cost $20/mo. We compare real message limits, model access and rate caps side by side, plus a pay-per-use option that costs far less.

Haiku $0.10/$0.50, Sonnet $2/$10, Opus $4/$20 per million tokens. What that means per actual message, and 4 ways to cut the bill. Free calculator.

An agent is a loop: read the page, pick a tool, act, repeat. What happens on each pass, and why perception decides everything downstream.

No Selenium, no Playwright, no selectors. Automate repetitive web work with plain English, using worked examples you can copy today.

Ten things worth handing to an AI side panel today, from summarising a spec to filling a form. Copy the prompt, see the result.

Draft, tighten and re-pitch text in any text box on any site. Prompts for tone, length and audience, with no pasting into another tab.

ChatGPT, Claude, Gemini, Copilot and Perplexity free plans checked against each official pricing page: models, caps, and when paying is worth it.

Pull a prospect brief off a company site and LinkedIn, draft the outreach and log it to the CRM. Sales prompts that survive real use.

We timed both. Accessibility-tree reads take 50-200ms, screenshot vision takes 3-8s. A 15-step task costs $0.30 vs $1.20. Benchmarks inside.

Which permissions actually matter, what your page data does after it leaves, and the nine checks to run before you install. Free checklist.
