ChatGPT vs Claude vs Gemini vs Grok: AI Assistants Compared (2026)

Disclosure: ainewsandreviews.com uses Grok Bot, xAI’s agent product, in its own work. We scored it by the same standards as every other tool here.

Updated Oct 31, 2026. All pricing and free-tier details were checked against each company’s official pages on October 26, 2026. Prices are in US dollars and exclude tax. Plans and prices change often, so check the linked pages before you buy.

How we scored: these scores are an editorial comparison based on each company’s published features, pricing, free-tier access, availability and safety controls. We didn’t create accounts or pay for plans for this piece, so we didn’t run hands-on benchmarks. Every tool was judged on the same five things: capability, value (including the free tier), availability, privacy and control, and how well it fits its intended users.

ChatGPT (OpenAI)

What it is: OpenAI’s chat assistant. It covers writing, voice, image creation, deep research, the Codex coding tool and ChatGPT Work, an agent that works on your tasks (ChatGPT pricing).

Pricing (checked 2026-10-26):

• Free: OpenAI lists unlimited text chats with GPT-6, subject to abuse guardrails. Uploads, image creation, voice, deep research and Codex are limited (pricing).
• Go: OpenAI says Go may include ads. Its price wasn’t in the text of the official pages we could read, so we’ve listed it as not published (Go help).
• Plus: $20 a month (Plus help).
• Pro: three tiers, at $100, $200 and $500 a month (Pro tiers).
• Billing: Go, Plus and Pro are monthly only (Go help).

Cons

• Go may show ads (pricing).
• Plan structure is complicated: four consumer tiers and many model names.

Who it’s for: students, including Study mode on every plan; writers; coders who use Codex; and small businesses, which can use the Business plan from 2 users (pricing).

Score: 8.6/10.

Grok (xAI)

What it is: xAI’s chat assistant, covering Grok Chat, Voice, Imagine for images and video, and Build. It’s sold through The X Subscription, which also covers X features (x.ai pricing).

• Image and video creation on Premium.

Cons

• The free tier’s limits aren’t published as numbers (pricing).

Score: 7.8/10.

Grok Bot (xAI)

What it is: xAI’s agent product. You create named “Bots” that each get their own cloud computer, use your apps and websites, run in parallel around the clock, learn routines from demonstrations, and ask for approval when needed (Grok Bot). The product is officially called “Grok Bot”.

Pricing (checked 2026-10-26): there is no free tier. Grok Bot is included with Premium ($30 a month), Super ($100 a month) and Ultra ($200 a month). The Free and Plus plans don’t include it (x.ai pricing). Grok Bot use draws on the same weekly pool as Grok and Cursor. Once the pool runs out, extra use comes from prepaid credits (Grok Bot plans help).

Pros

• It carries out tasks inside your tools, not just in chat (Grok Bot).

Muse (Meta)

What it is: we confirmed this from Meta’s own pages. Muse is Meta’s “personal AI agent,” announced on September 8, 2026. It runs on Muse Spark, Meta’s model, inside a dedicated cloud virtual machine called Muse Secure VM. You can use it in the Muse app, on the web and in WhatsApp. It can browse, fill out forms, set reminders and create files (Meta newsroom; Meta Help Center).

Pricing (checked 2026-10-26): free with a usage limit. The Power plan costs $20 a month for 500M Muse tokens a week. The Maximum plan costs $100 a month for 3B Muse tokens a week. Meta says Muse and its subscriptions are “in limited testing” and not available everywhere (Muse subscriptions).

Pros

• A free agent tier, which is rare among agent products.
• A separate “Sentinel” agent must approve anything Muse sends to the internet. Muse also checks with you before sensitive actions such as sending email or buying something, and keeps a full audit trail (Meta newsroom).
• Meta says your conversations and VM data aren’t shared with Meta’s ad systems, and you can opt out of training (Meta newsroom).

Cons

• Limited testing with regional availability; subscribers must be 18+ (subscriptions).
• Requires a Meta account.
• Meta warns Muse “may be inaccurate or take unexpected actions” (Help Center).

Who it’s for: everyday users who want reminders, errands and goal planning in a chat they already use, such as WhatsApp.

Score: 7.4/10.

Niche pick: CFO Silvia (finance)

What it is: we confirmed this from the official site and an official press release. Silvia is a personal “AI CFO” for investors. You connect your accounts, track assets and liabilities, and ask about cash flow, investments and goals (cfosilvia.com). It’s made by CFO Silvia, Inc., which ProCap Financial (Nasdaq: BRR) acquired in April 2026 (ProCap Financial press release). The official spelling is “Silvia”; some coverage spells it “Sylvia.”

Pricing (checked 2026-10-26): the official site lists Silvia as “A free AI CFO for everyone,” with a price of $0 (cfosilvia.com). Paid plans: not published.

Pros

• Free, according to the site.
• Covers a wide range of assets, including stocks, bonds, crypto, real estate and collectibles (press release).
• Some resources work without signing in (cfosilvia.com).

Cons

• Narrow focus: finance only.
• You have to connect financial accounts to get the full benefit.
• It isn’t a licensed adviser. The site says it helps you prepare to “discuss them with your financial, tax, or legal adviser” (cfosilvia.com).

Who it’s for: investors who want one view of their net worth.

Score: 6.8/10.

Verdict

ChatGPT, Claude and Gemini are the safest starting points, and all three have useful free tiers. Gemini is the cheapest upgrade. Agents are the new category: Grok Bot is the more established paid option, and Meta’s Muse is the free one to try if it’s available where you live. Specialists like CFO Silvia make sense alongside a general assistant, not instead of one. Whatever you pick, check AI answers and approve agent actions yourself.
