An AI agent doesn't just answer; it plans, browses and acts across multiple steps. That makes it powerful and expensive, since every step costs credits, so match the agent to the kind of task you'll delegate.
Manus ($20/mo) is the best general-purpose agent for research and multi-step web tasks, with a usable free tier. Genspark is better when the output is slides, docs or video. For email and scheduling automation, Lindy AI is the specialist.

Monthly prices in US dollars before tax, from each vendor's official pricing (US list price; weekly-billed plans converted to a monthly figure). Updated October 7, 2026
Plans, browses and delivers multi-step tasks on its own; Free includes 300 daily credits, and Pro adds 20 concurrent tasks. Complex jobs burn credits fast, and its ownership is clouded after Chinese regulators ordered Meta's acquisition unwound.
Pick it if: you want to delegate open-ended research and reports.
Full Manus pricing →Routes across 70+ models to turn one prompt into slides, docs or video, with core chat and image generation free on Plus through Dec 2026. Video and voice tasks drain credits.
Pick it if: you want ready-to-use files, not just answers.
Full Genspark pricing →A no-code builder for agents that triage inboxes, schedule meetings and automate workflows across 100+ apps. There is no free plan, only a conditional 7-day trial.
Pick it if: repetitive inbox and calendar work eats your day.
Full Lindy AI pricing →Drives a real browser through research, bookings and data collection, from $19/mo. It's a younger product, and the free 1,000 one-time credits cover only about 4 tasks.
Pick it if: your tasks are multi-site web chores.
Full Fellou pricing →Books travel, drafts emails and checks out with your card, from its own app or WhatsApp, with a generous free token allowance. US-only and 18+, and it needs deep access to your email and calendar.
Pick it if: you're in the US and comfortable giving an agent access to personal accounts.
Full Meta Muse pricing →ChatGPT Pro ($100–200/mo) includes about 50 Deep Research runs a month on the lower tier, while the higher tier adds Operator and 250 runs. That's a lot to pay for agent features alone.
Pick it if: you already need Pro-level ChatGPT usage.
Full ChatGPT pricing →Manus, Genspark and Meta Muse all have free allowances; use them on a real task before paying. Agents that act for you (Lindy, Meta Muse) need access to email, calendar or payment details, so check what each one can do without asking first.
Manus Free gives 300 daily credits and one concurrent task. Meta Muse's free tier is generous but US-only. Genspark Free refreshes about 100 credits a day.
Manus for open-ended research and web tasks; Genspark when you want slides, docs or video as the output and access to many models in one subscription.
