Piotr Olszewski · updated October 12, 2026An AI agent is a program that doesn't just answer - it plans the steps and carries them out on its own: it opens pages, clicks, fills in forms, writes files and connects to other apps. In 2026, for one-off jobs like "gather the data and give me a finished report, deck or web page", Manus and Genspark are the best fit. For work in your own browser, on your own logged-in accounts, Claude in Chrome and ChatGPT's agent mode look the most mature. For processes that should run by themselves every day (inbox, CRM, reports), automation platforms with agents are the better choice: Lindy, Zapier and n8n.
Before you pay: agents are good at tasks a person would finish in 15-60 minutes of clicking. On long, multi-step processes involving logins, payments and unusual websites, they still get lost fairly often and need supervision.

What agents can actually do (and what they can't)
Based on vendor documentation and the vendors' own warnings:
- Good at: pulling information from a dozen pages into a report, preparing decks and documents, comparing offers, filling in repetitive forms, moving data between systems, tidying up an inbox.
- So-so at: tasks that require logging into many services, websites with unusual interfaces, multi-step processes that take more than an hour.
- Poor or not at all: payments and transactions (vendors advise against it), CAPTCHAs, sites that block bots, decisions that need knowledge the task doesn't contain.
- Biggest risk: prompt injection - instructions hidden on a web page that hijack the agent. On the Claude in Chrome page, Anthropic says plainly that the built-in safeguards are not foolproof and advises against using the agent for banking or medical data.
Manus
Manus is a "from task to finished file" agent: you type a request such as "prepare a deck on the e-bike market" or "build a one-page business website", and Manus plans the steps, browses the web and hands back the result. It runs in the browser, in mobile and desktop apps, and also has a browser-operator mode. On its pricing page the vendor showcases use cases like graphic design, slides, image generation, video editing and even simple games.
- Who it's for: freelancers and small teams who want to hand off research-and-execution work.
- Price: the docs describe Free (limited monthly credits), Pro and Team plans; I couldn't read the exact amounts or credit allowances from the pricing page in October 2026.
- Downsides: billing is in credits that depend on task complexity, so it's hard to predict what a single job will cost.
Genspark
Genspark is a workspace with an agent that produces presentations, documents, spreadsheets, images, video and code from a single interface. Under the hood it uses models from several companies (including OpenAI, Google, Anthropic and xAI, per its catalog) and picks one for the task.
- Who it's for: people who make a lot of decks and reports and don't want to juggle five tools.
- Price: the pricing page blocked automated reading in October 2026, so I'm not quoting amounts.
- Downsides: output quality depends on the chosen model, and credits burn fast on video and images.
ChatGPT agent
Agent mode in ChatGPT combines a virtual browser, search and file work. The agent runs on its own remote computer: it browses pages, fills in forms, creates spreadsheets and presentations, and for sensitive steps (logins, purchases) it asks you to take over or confirm.
- Who it's for: people already paying for ChatGPT who want to delegate web tasks without installing anything.
- Price: agent mode is part of paid ChatGPT plans; OpenAI's pricing page blocked automated reading in October 2026, so I haven't confirmed current prices and limits.
- Downsides: it works in a remote browser, not yours, so on sites that need a login you have to take control; long tasks can take a dozen minutes or more.
Claude (Claude in Chrome, Cowork, Claude Code)
Anthropic's Claude comes in several agentic forms. Claude in Chrome is an extension that, according to Anthropic, navigates websites, reads them, clicks, types and fills in forms - in your own browser, on your logged-in accounts. Anthropic lists uses such as pulling data from dashboards, working in internal systems, cleaning up an inbox and updating a CRM. The extension works together with Claude Cowork and Claude Code (the coding agent).
- Who it's for: people who work across many web-based business systems, and developers (Claude Code).
- Price: per Anthropic, Claude in Chrome is available on all paid plans. Pro costs $20 a month or $17 a month billed annually; Max starts at $100.
- Downsides: it acts on your real accounts, so mistakes have real consequences. Anthropic itself advises against sensitive uses and asks you to review steps before any financial action.
Comet
Comet (not in the directory yet) is Perplexity's browser with a built-in assistant that can carry out tasks across your open tabs: comparing products, summarizing, filling in forms.
- Who it's for: people who want an agent built into the browser rather than an extension.
- Price: the Comet page blocked automated reading in October 2026, so I haven't confirmed access terms or pricing.
- Downsides: switching browsers is a big step, and an in-browser agent is exposed to the same prompt injection attacks as other tools of this kind.
Lindy
Lindy is an agent-style assistant for everyday office work: inbox management, meetings, scheduled routines and 1,500+ integrations. What I like is that the vendor publishes rough credit usage: everyday tasks 2-250 credits, deep work (research reports, queue triage) 250-1,000, complex builds (dashboards, workflows) 1,000-2,500.
- Who it's for: freelancers, managers and small businesses buried in email and meetings.
- Price: per the pricing page as of October 12, 2026 - a free start with $50 in credits valid for 7 days and no credit card, then the Team plan from $49.99 a month for 5,000 credits, plus top-ups at $10 per 1,000 credits. Monthly credits don't roll over.
- Downsides: with 5,000 credits on the entry Team tier, a handful of "deep work" or build tasks can eat most of the monthly allowance.
Opera Neon
Opera Neon is a browser built around agents: several specialized agents (from a quick agenda to deep research with a document), work based on the context of your open tabs, and the option to connect tools via MCP and CLI. Opera stresses that sensitive data stays on the device and isn't used for training.
- Who it's for: people who want agents inside the browser and like Opera.
- Price: $19.90 a month for the agent features.
- Downsides: paying a subscription for a browser takes some getting used to, and the agents only work inside it.
Gemini in Chrome
Gemini in Chrome is the assistant built into Google's browser. It answers questions about your open tabs, compares information across several pages, summarizes articles and YouTube videos and, according to Google, can carry out some tasks for you.
- Who it's for: people who are staying with Chrome and have a Google account.
- Price: the feature set depends on your Google AI plan (AI Plus, AI Pro and above); prices vary by country, so check the Google One plans page for your region. I haven't confirmed which agent features sit in which plan.
- Downsides: Google rolls out agent features gradually and not all of them are available in every country at once.
Zapier Agents
Zapier is the classic automation tool, and agents are its newer layer: instead of a rigid "if X, do Y", you describe the task and the agent decides which integrations to use. According to the pricing page, basic agent access is included in every plan, while expanded access is a paid add-on billed in a separate unit ("activities").
- Who it's for: companies that already use Zapier or have lots of SaaS apps to connect.
- Price: Free at $0 (100 tasks a month), Professional from $19.99 a month billed annually (750 tasks), Team from $69 a month billed annually.
- Downsides: two separate meters (tasks and agent activities) make it harder to work out the cost.
n8n
n8n is a platform for automation and for building your own AI agents, with a visual editor and the option to write code. Its key advantage: you can run the Community edition for free on your own server, and in the cloud you pay per workflow execution, not per step.
- Who it's for: technical users, automation agencies and companies that want to keep data in-house.
- Price: Community self-hosted is free; cloud Starter is €20 a month (2,500 executions), Pro €50 a month (10,000 executions), Business €667 a month - per the pricing page, annual billing saves 17%.
- Downsides: it takes more technical know-how than Zapier or Lindy, and a self-hosted server needs maintenance.
Browser Use
Browser Use is an open-source project (MIT license) and a platform with a ready-made browser agent and remote browsers available through an API. It's a tool for developers building their own agent-powered products.
- Who it's for: developers and startups building web automations.
- Price: usage-based billing with a trial; I didn't check the amounts on the official pricing page.
- Downsides: you can't get far without programming.
How to choose
- One-off task with a finished file at the end - Manus or Genspark.
- Work inside your own services and business systems - Claude in Chrome (runs on your accounts) or ChatGPT agent (runs in a remote browser).
- Daily inbox and meeting handling - Lindy.
- Connecting many apps across a company - Zapier, or n8n at larger scale and on your own server.
- You want the agent inside the browser itself - Opera Neon, Comet or Gemini in Chrome.
- You're building your own product - Browser Use or n8n.
- Start with one repetitive task - measure the time before and after before you buy an annual plan.
Common mistakes
- Giving an agent access to banking and payments - vendors themselves advise against it. An agent can be manipulated by page content.
- No supervision on the first runs - watch what the agent clicks before you trust it with unattended tasks.
- Prompts that are too vague - "do my marketing" ends with a burned credit balance. Give the goal, output format, sources and constraints.
- Ignoring credit costs - a single complex build in Lindy can use up to 2,500 credits.
- Pasting in customer data without reading the terms - check where the vendor processes data and whether it trains models on it.
- Confusing an agent with automation - if a process is always the same, a plain workflow in Zapier or n8n will be cheaper and more reliable than an agent.
FAQ
Is there a free AI agent?
Yes, with limits. n8n Community is free to self-host, Zapier has a free plan with basic agent access, Manus has a Free plan with limited credits, and Lindy gives you $50 in credits for 7 days.
What is the difference between an AI agent and a chatbot?
A chatbot answers a question. An agent gets a goal and carries out the steps itself: it opens pages, clicks, fills in forms, creates files and connects to other apps, then hands you the result.
Can an AI agent shop for me?
Technically some agents can get as far as the checkout, but vendors recommend that a human approves payments and any other irreversible step. Anthropic explicitly advises against using its agent for banking.
Manus vs ChatGPT agent: which is better?
Manus is geared toward delivering a finished product (a deck, website or report); ChatGPT agent toward doing web tasks within a conversation. If you already pay for ChatGPT, start with its agent; if you mainly need finished files, try Manus's free plan.
Are AI agents safe to use?
They're as safe as the access you give them. The biggest risk is prompt injection - instructions hidden on a page that can hijack the agent. Give agents minimal permissions, use separate accounts where you can, and manually approve every step involving money or personal data.
What is the best AI agent for business automation?
For connecting existing SaaS apps, Zapier is the easiest start; for higher volumes or keeping data on your own server, n8n; for an assistant that handles email and meetings, Lindy.
