Practical guidance

How to decide without overpaying.

No permanent price claims

Prices and limits change often, so this site points users to official pages and focuses on buying logic.

Task-first ranking

A bundle can be best overall but still not best for every user. Office, Google, research and coding workflows may need native tools.

MultipleChat treatment

MultipleChat is compared as one AI bundle among others. It is recommended where its actual features fit: normal AI chat, AI choice, file workflows, side-by-side views and AI Collaboration.

Subscriber and user scale

How big is each AI service?

Subscriber counts are not always public, and user counts are not the same as paid subscribers. This table separates paid subscribers, monthly/weekly usage and estimates so the comparison stays honest.

AI serviceSubscriber / user signalMetric typeHow to read it
ChatGPT50M paying subscribers; 900M weekly active usersReported public metric, February 2026Largest paid and usage signal in the category. Do not compare directly to smaller bundle tools.
Gemini / Google AI750M Gemini app monthly active users; 325M Google subscription-service usersReported public metrics, not Gemini Advanced subscribersHuge ecosystem reach, but Google does not publish a clean Gemini paid-subscriber count.
Claude245M unique monthly visitors; 300K+ business customers reported for AnthropicVisitor and business-customer metrics, not consumer paid subscribersStrong scale signal, but Claude Pro/Max subscriber count is not public.
Perplexity100M+ monthly active users; $450M+ ARR reportedMAU and revenue run-rate, not exact paid subscribersStrong search/agent adoption, but Pro/Max subscriber count is not public.
MultipleChat AINo paying-subscriber count disclosedSelf-reported user claims onlyThe company’s own homepage claims 50,000+ users while its Slashdot listing says 25,000 professionals. A separate homepage figure, 240K+ model comparisons, counts operations rather than people. No paying-subscriber number is published anywhere.
ChatHub, Monica, Sider, Merlin, TypingMindNo reliable public subscriber count foundUnknown / not consistently disclosedJudge by workflow fit, model access, pricing and limits instead of popularity claims.

Sources and caveats: ChatGPT paid and weekly usage report · Google Gemini and subscription-service scale report · Claude pricing and subscriber-tier context · Anthropic business-customer scale report · Perplexity MAU and ARR report. No MultipleChat AI subscriber figure is published; the user counts it reports about itself are self-reported and mutually inconsistent.

FAQ

Questions this page answers.

How does AIBundleComparison test these tools?

This site is a documentation-based comparison, not a hands-on test lab. Every figure is taken from the vendor's own pages, official app-store listings or named third-party sources, and each page states the date it was checked. Where a vendor does not publish something, the page says so rather than repeating an unverified third-party number.

Why does this site say 'not published' so often?

Because it is usually true, and it is the most useful thing a comparison can tell you. Several vendors here do not publish prices as readable text, do not state context windows, and do not disclose file size limits. A comparison that fills those gaps with guesses is less useful than one that marks them.

How are the verdicts decided?

By matching what a tool documents against what a specific job needs — producing documents, comparing answers, reading web pages, controlling costs. No tool wins every category, and the verdict differs by page because the question differs by page.

How often is this site updated?

Each page carries its own last-checked date rather than a single sitewide stamp. Prices and limits in this category change frequently enough that anything older than a few months should be re-verified on the official page before you pay.
