Three subscriptions. Twenty dollars each. Near-identical marketing copy.

If you're reading this, you've probably already noticed the uncomfortable part: the pricing pages don't help you choose. ChatGPT Plus, Claude Pro and Google AI Pro (the plan formerly sold as Gemini Advanced) all cost about $20/month, all promise "more usage" and "advanced models," and all of them will happily take your money without telling you what they're bad at.

So let's do it properly. What follows is what each $20 actually buys in 2026, who each one is genuinely the right answer for — and the case for not buying any of them.

The prices, straight

Worth getting the full ladders on the table first, because the $20 tier is not the only option any of them sell, and two of the three have added cheaper entry tiers that didn't exist a year ago.

	OpenAI	Anthropic	Google
Free	$0	$0	$0
Entry tier	Go — $8/mo	—	AI Plus — $4.99/mo
The $20 tier	Plus — $20/mo	Pro — $20/mo ($17/mo billed annually)	AI Pro — $19.99/mo
Power tier	Pro — $100/mo (5x) or $200/mo (20x)	Max — from $100/mo (5x or 20x)	AI Ultra — $99.99/mo (5x) or $199.99/mo (20x)

Two things jump out.

First, the middle of the market got cheaper. OpenAI's Go tier ($8) and Google's AI Plus ($4.99, cut from $7.99 in June 2026) both exist because a lot of people were paying $20 for maybe 15% more usage than free. If your actual complaint is "I keep hitting the free limit" rather than "I need the frontier model," the entry tiers are the honest answer and nobody's marketing page is going to tell you that.

Second, the $20 tiers are converging on price and diverging on substance. They cost the same. They are not the same product.

What each $20 is actually for

ChatGPT Plus — the widest surface area

Plus buys you OpenAI's current flagship plus the ecosystem built around it: image generation, voice, the app store of custom GPTs, and the broadest third-party integration story of the three. Note the ceiling, though — OpenAI reserves its heaviest features and highest limits for the $100/$200 Pro tiers, and the $8 Go tier explicitly excludes Agent mode, Deep Research and top-tier model selection.

Pick Plus if: you want one AI that does the most different kinds of things, you use image and voice regularly, or you depend on a specific custom GPT or integration.

The catch: you're buying an ecosystem, not a model. If what you actually needed was the best writing or the best long-document reasoning, you may be paying for a lot of surface area you never touch.

Claude Pro — the one people keep for the writing and the code

Pro is the narrowest of the three and unapologetic about it. There's no image generation to speak of, and the consumer feature list is shorter. What you get instead is Anthropic's flagship, Projects for organizing long-running work, Research, and — the reason a lot of developers pay for it — Claude Code included in the subscription rather than sold separately.

Anthropic is also the only one of the three offering a real annual discount on the $20 tier: $17/mo billed annually.

Pick Pro if: you write for a living, you work with long documents, or you code. These are the three things Claude is most consistently preferred for, and the $17 annual price makes it the cheapest of the three $20-tier subscriptions if you're confident enough to commit for a year.

The catch: it's a specialist. If you also want image generation and a general assistant, you'll feel the gaps within a week.

Google AI Pro — the one that's cheapest if you're already in Google

AI Pro is priced as a subscription and structured as a bundle: Gemini's flagship, 4x the free tier's usage limits, Flow credits, Deep Search, and — the part that quietly does the most work — 5TB of cloud storage.

That storage line matters more than it looks. If you're currently paying Google separately for storage, the marginal cost of AI Pro is not $19.99, it's $19.99 minus whatever your storage plan already costs. For a lot of people that makes it the cheapest of the three by a wide margin.

Pick AI Pro if: you live in Gmail, Docs and Drive, or you're already paying Google for storage. The integration is the product, and no amount of API access replicates having the model already inside the document you're editing.

The catch: Google has repriced and restructured this line three separate times in 2026 (AI Plus cut to $4.99 in June, the Ultra tier split in two at I/O). Whatever you sign up for, check that it still means the same thing in six months.

The decision, in one paragraph each

You mostly want one assistant that does everything, including images and voice → ChatGPT Plus.
You write or code for a living and want the best tool for that specifically → Claude Pro, annual, $17/mo.
Your work already lives in Google Workspace, or you pay Google for storage → Google AI Pro.
You keep hitting the free tier's limits but don't need the flagship model → ChatGPT Go at $8 or Google AI Plus at $4.99. Genuinely. Don't pay $20 to solve a rate-limit problem.

That's an honest answer for most people, and if one of those four lines described you cleanly, you can stop reading.

The problem with the honest answer

Here's what the four-line version doesn't cover, and it's the situation an increasing number of people are actually in.

You don't have one use case. You draft in one model because it writes better, sanity-check the reasoning in another because it catches different mistakes, and use a third for anything that touches your Google Docs. The models are genuinely different — that's the whole reason the comparison is hard — and the natural consequence of them being different is wanting more than one.

Do that, and the math stops being $20:

ChatGPT Plus + Claude Pro = $40/month
All three = ~$60/month, or $720/year

$720/year is not a "which one" decision anymore. And you're not getting 3x the value, because most of what you're paying for in each subscription is the interface and ecosystem — which you already have two of.

There's also the friction nobody prices in: three tabs, three conversation histories, three separate memories of who you are, and no way to hand a conversation from one model to another except by copy-paste.

The fourth option: don't buy any of them

If you recognized yourself in that last section, the useful question isn't "which subscription" — it's "why am I buying access to models one vendor at a time?"

That's the gap AIWITH.CHAT is built for. One subscription, every flagship model, same chat window:

	ChatGPT Plus	Claude Pro	Google AI Pro	All three	AIWITH.CHAT
Monthly	$20	$20	$19.99	~$60	$9.9
Yearly	$240	$204 (annual rate)	~$240	~$684+	$95.9 (≈$7.99/mo)
GPT-6	✅	❌	❌	✅	✅
Claude Fable 5	❌	✅	❌	✅	✅
Gemini 3.1 Pro	❌	❌	✅	✅	✅
DeepSeek V4.1 / Kimi K3	❌	❌	❌	❌	✅
Switch model mid-conversation	❌	❌	❌	❌	✅

The Standard plan is $9.9/month — half of any single one of the three — and includes 3.2M credits/month, roughly 350 flagship-model conversations or 2,100+ conversations on lighter models like DeepSeek. On the annual plan that drops to about $7.99/month, which is less than ChatGPT's entry tier. If you need more headroom, Premium is $19.9/month for 7.2M credits — still the price of one ChatGPT Plus, for all of them.

The part that's hard to appreciate until you've used it: switching models inside one conversation. Draft with one, ask another to critique the draft, and the second model can see the first one's output because it's the same thread. Three subscriptions can't do that at any price — the context doesn't cross the vendor boundary.

New accounts get free credits, so you can check whether the multi-model workflow is actually how you work before paying anything.

Where the honest limits are

To be fair about it, three subscriptions do buy you some things a single aggregator doesn't:

Deep native integration. Google AI Pro inside Google Docs, or ChatGPT's ecosystem of custom GPTs and connectors — those live inside the vendor's own product and can't be replicated from outside.
Bundled extras. AI Pro's 5TB of storage, Claude Pro's inclusion of Claude Code — if you actively use those, they're real value you'd lose.
Day-one access to brand-new features. New vendor features land in the vendor's own app first.

So the honest version of the recommendation:

If you use exactly one model and you use its ecosystem features heavily, buy that vendor's subscription. Pick the one from the four-line decision list above. It'll serve you better than any aggregator.

If you find yourself wanting a second subscription — that's the point where the math flips. $40/month for two, or $60 for three, buys you fragmented context and three separate bills. $9.9 buys all of them in one window.

Bottom line

ChatGPT Plus ($20) — the widest feature set. Best if you want one assistant for everything.
Claude Pro ($20, or $17 annual) — the best writing and coding tool of the three, and the cheapest at the annual rate.
Google AI Pro ($19.99) — the cheapest in practice if you're already in the Google ecosystem, because of the 5TB storage bundle.
ChatGPT Go ($8) / Google AI Plus ($4.99) — the right answer if your real problem is rate limits, not model quality. Most people who upgrade to $20 should have bought one of these.
AIWITH.CHAT ($9.9) — the right answer if you want more than one of them, which most people eventually do.

The trap in this comparison isn't picking the wrong $20 subscription. It's ending up with two or three of them because none of them alone was quite right.
