Best Free AI Agents for Personal Use

Quick comparison: free AI agents at a glance

What can a free AI agent actually do for you?

A chatbot answers your question. An agent takes a goal, breaks it into steps and works through them, often using a browser, files or other apps along the way. Ask Manus for a trip-planning doc or Genspark for a short slide deck on a topic, and it goes off and builds the thing instead of handing you a list of tips.

For personal use, that means jobs like comparing products before you buy, pulling research into a tidy report, turning notes into slides or a spreadsheet, and keeping on top of email and meetings. The free plans are big enough to see whether an agent suits you. They run out fast on heavy jobs, because every step spends credits (the points these tools use to meter work).

Free plans: the limits that matter

The best free AI agents, one by one

Manus

Our pick for: the best all-round free agent.

You describe a goal and Manus plans the work and runs it in its own virtual computer. It handles research, slides, spreadsheets and even small web apps. The free plan gives you 300 credits a day, one task at a time and two scheduled automations, so you can set it to do a small job on a timer.

• Free plan: 300 daily refresh credits (Manus 2.0 lite only), capped at 1,500 daily credits a month.
• Cheapest paid plan: Pro, US$20/month for 4,000 credits. A US$40/month tier gives 8,000. Manus says yearly billing saves 17%.
• Good: a real daily allowance, plus scheduled tasks on the free plan.
• Watch out for: big jobs eat credits, and the free credits only work with the lite model.

Genspark

Our pick for: research, slides and documents.

Genspark is an AI workspace built around a Super Agent that researches a topic, then builds slides, sheets and docs from it. It also lets you chat with several AI models in one place.

• Free plan: 100 credits a day, 1 GB of AI Drive and limited access to models and agents. The daily refill stops once you hit a lifetime allowance, so treat it as a long trial.
• Cheapest paid plan: Plus, US$24.99/month, or US$19.99/month billed yearly (US$239.99/year), with 10,000 credits a month and commercial use.
• Good: built to turn research into finished documents.
• Watch out for: the free credits don't last forever.

ChatGPT (ChatGPT Work)

Our pick for: people who already live in ChatGPT.

OpenAI retired its old agent mode, and ChatGPT Work is now its tool for longer, multi-step tasks. Free users get limited Work access in the ChatGPT desktop app. The cloud browser, which lets ChatGPT browse websites for you, needs a plan above Go.

• Free plan: limited ChatGPT Work access on desktop.
• Cheapest paid plan: OpenAI's pricing page showed no dollar amounts when we checked today, so we've left the price out. Plus lists expanded access to ChatGPT Work.
• Good: no new app or account if you already use ChatGPT.
• Watch out for: the free Work allowance is small, and web browsing for you sits behind paid plans.

Lindy

Our pick for: email, calendar and other routine chores.

Lindy is an assistant that handles email, scheduling and other repeat work for you. It's the most "personal assistant" of the bunch, and the most like a trial on the free side.

• Free plan: US$50 in credits that last 7 days.
• Cheapest paid plan: Team, from US$29.99/month per user for 3,000 credits, billed monthly. Extra credits cost US$10 per 1,000.
• Good: built for inbox and calendar work rather than one-off research.
• Watch out for: after a week, you're paying or you're done.

Muse (Meta)

Our pick for: everyday errands, if you can get it.

Muse is Meta's personal AI agent. It takes actions for you and connects to other apps, and paid subscribers in the US can have it phone businesses for things like reservations.

• Free plan: yes, with a usage limit that refreshes. Meta doesn't say how big it is, and the rollout is limited.
• Cheapest paid plan: Power, US$20/month. Maximum is US$100/month. No yearly plan shown.
• Good: aimed squarely at personal errands.
• Watch out for: it isn't available everywhere yet, and the phone calls are paid-only.

Which AI agents need a paid plan?

A few big names have agent features, but not on their free plans:

• Google Gemini: Tasks in Gemini and Chrome auto browse are on Google AI Pro (US$19.99/month or US$199.99/year) and up, and auto browse is US only. The free Gemini app is a chat assistant.
• Claude: the free plan is generous for chat, but scheduled and handoff tasks need Pro, US$20/month or US$17/month billed yearly (US$200 up front).
• Perplexity Comet: the free Perplexity tier includes no Comet Assistant agent queries. We've left Perplexity's prices out today because its Comet page didn't load when we checked.

Which free AI agent should you pick?

Our verdict

Start with Manus. Its daily credits make it the easiest free agent to live with, and two scheduled automations on a free plan is a nice bonus. If your jobs end in a document or a deck, give Genspark a go too, while its lifetime allowance lasts.

Keep the first jobs small and boring: a price comparison, a reading list, a slide outline. Agents get things wrong, and you'll learn more from a cheap mistake than an expensive one. Only pay once one of them saves you real time every week.
