The best Perplexity Comet alternatives

Better than Perplexity Comet if you want the most capable free personal agent and you're comfortable giving Meta access to your accounts.

Muse is the most complete personal agent you can get today: it books, buys, handles email and forms, and it's free to start. It also has the strongest published safeguards here: approvals before sending or buying, a full audit trail, and a separate agent that checks anything it sends out. The catch is trust: it wants deep access to your email, calendar and payments, it's run by Meta, and reporting found that some of its beta phone calls were completed by human workers.

Better than Perplexity Comet if you can get an invite and want an agent you text that books, buys and calls businesses for you.

Instinct is the most capable errand-runner you can text, and it really does pay and book for you, using virtual cards you approve. You need an invite to get in, prices haven't been published, and reviewers have raised privacy and liability questions, so check what you're agreeing to.

Better than Perplexity Comet if you want a free, proactive agent that can actually order, pay and book on websites for you.

Hark Pro is one of the strongest new agents: Handoff works through real websites, every feature is in every plan, and the free tier is generous. It's brand new, it asks for email, calendar and card access to work well, and it can't make phone calls yet.

Better than Perplexity Comet if you want a free agent in your texts that books, calls businesses and chases refunds.

Pally is the best free agent you can text: it books, calls and chases refunds, and it asks before anything consequential. It plans to earn fees from merchants when you buy through it, though it says merchants can't pay to change its picks, and working through websites needs the $95-a-month Cloud Mac add-on.

Better than Perplexity Comet if you already pay for X Premium or SuperGrok and want bots that run recurring jobs you can teach them.

Grok Bot is a powerful, flexible agent, especially for recurring jobs you can teach it once. It's not cheap ($30 a month and up), its usage pool is shared with Grok and Cursor, all your Bots share the same logins, and xAI's own pages couldn't be checked, so plan details come from third-party reports.

Better than Perplexity Comet if you want a desktop browser built around an agent that can also run tasks on a schedule.

Neon is the most capable dedicated agent browser on the desktop, and scheduled tasks are a real plus. It's $19.90 a month for the agents, has no phone app, and a review reports agent data is kept on Opera's servers for a year.

Better than Perplexity Comet if you want help reading and researching in your browser, not an agent that acts.

Dia is a pleasant AI browser for reading and research, with good personal memory. As an agent it does the least here: it doesn't click through sites to finish errands, its free plan has no AI, and its focus is shifting to business use.

Better than Perplexity Comet if you want to experiment with scheduled, multi-site browser workflows.

Fellou can work through multi-site tasks and schedule them. Paid plans buy few tasks per dollar, the free credits are one-time, reviewers dispute its platform support, and a prompt-injection flaw reported by Brave was never publicly confirmed as fixed.
