What Is This
AI integrated with X (Twitter), featuring real-time information and an edgy personality.
Free Version Limitations
The official site publishes no concrete usage figures at all for the free tier, and this site does not fill in an estimate. Verification trail (exhausted): grok.com/pricing returns HTTP 200 but the whole page is rendered by JavaScript, so the static HTML contains no plan names or price text, only Stripe price IDs; opening it in a real browser hits a Cloudflare human-verification wall, which we do not bypass; x.ai/grok returned 403 three times in a row (blocked, not 404). What can be confirmed: free use does exist and is US$0, because in the in-app purchase list on the official Apple App Store listing every paid item belongs to the SuperGrok range, so basic chat requires no payment. Third-party felloai.com states plainly that xAI has never published free-tier numbers anywhere, and says the free tier only gets the lighter Grok 4 Mini, includes basic real-time web and X search, has limited voice mode, and that image and video generation were removed from the free tier on 2026-03-19. The widely circulated figure of about 10 messages every 2 hours has no official backing and is not used here. (Verified 2026-08-09)

Terms Of Use
Requires an X (Twitter) account; credit card verification is required in Taiwan; partial Traditional Chinese support in the interface
US$10/month. Price taken from the official listing on the Apple App Store's in-app purchase list (grok.com's pricing page is JS-rendered and the text can't be scraped).
The world's most widely used AI assistant, handling conversation, search, image generation, and voice all in one place
FreeNT$0/month, open to everyone. The official site lists the free-tier limits one by one: limited access to GPT-5.5 Instant, limited messages and uploads, limited and slower image generation, limited deep research, limited memory and context, limited Codex, limited ChatGPT Work desktop app. The only place the official site gives concrete numbers is the plan comparison table: free-tier GPT Instant total context window 27K (Go/Plus 54K, Pro 128K); free-tier single-input cap about 12 pages of text (Go/Plus about 40 pages, Pro about 250 pages); the context window for reasoning models is marked depends on the situation for the free tier (Go/Plus 256K, Pro 400K). Response time on the free tier is marked as limited by system resources and service conditions; only paid plans are fast. Chat history is unlimited on the free tier. Whether content is used for model training can be opted out of. The official site has never published a concrete messages-per-day figure, and this site does not fill in an estimate.

Long-form writing and document quality are its strengths, with the paid version including the Claude Code engineering tool
FreeThe quota is calculated based on a rolling 5-hour usage window (not simply resetting at a fixed number every day), and general conversations can be used for around 10-20 times, excluding Claude Code.
Google has the deepest ecosystem integration of AI, with a generous free version and frequent discounts for student plans.
FreeNT$0/month, free to anyone with a Google account. Model available: Gemini 3.6 Flash; the official site states plainly that access to 3.1 Pro may vary, meaning free-tier access to Pro fluctuates and is not guaranteed. Features included on the free tier: image generation and editing, Deep Research, Gemini Live, Canvas, Gems, Gemini Notebook (research and writing), the Google Flow creative studio, plus limited usage of Nano Banana Pro. Cloud storage 15 GB (shared across Gmail/Drive/Photos). How the quota is counted and when it resets, in the official footnote's own words: the Gemini app measures usage limits by compute, which depends on prompt complexity, the features you use and conversation length; usage resets every 5 hours, up to a weekly usage cap. In other words the free tier is not a fixed number of messages per day but a compute allowance that resets every 5 hours plus an overall weekly cap; long conversations, Deep Research and image generation burn through it faster than plain chat. When the quota runs out you can buy AI credits. The official site does not publish the specific compute figure for the free tier.
