Use AI is a multi-model AI chat app for the browser, iOS and Android that sells access to models from several AI labs through a single subscription. It is operated by Use AI Inc., and its homepage describes it as "Your AI Workspace", a place to reach leading AI models, research the web and get tasks done.
The central promise is breadth: the pricing page lists Claude, GPT, Gemini, Grok, DeepSeek, Kimi and GLM chat models behind one interface. Use AI Inc. provides access to third-party AI models and says it is not affiliated with or endorsed by their providers. The help center also stresses that Use AI is a separate service from Anthropic and OpenAI that gives access to models like Claude, GPT and Gemini under one subscription.
Premium models are metered through an allowance released weekly, and published prices differ between the pricing page, the app store listing and the terms. The product is young: an AI tool directory records the listing as added in February 2026, and the iOS app was first released in July 2026.
Paid plans unlock Claude Opus 5, Claude Opus 4.8, Claude Sonnet 5, Claude Fable 5.1, GPT-5.6 Sol, GPT-5.5, GPT-5.4, GPT-6 Astra, Gemini 3.8 Flash, DeepSeek V4 Pro, Kimi K3, Kimi K2.6, Grok 4.6 and GLM 5.2, with Claude Fable 5.1 reserved for Max. No separate OpenAI or Anthropic account is needed, because one Use AI subscription covers model access through the labs' APIs.
The company says it adds a lab's model when it is on par with or better than the current lineup, and that new models usually arrive within 24 hours of general availability.
Free includes limited web search. Deep Research, a paid feature, analyzes hundreds of web sources on a question and builds a structured report with citations for every claim. On Pro it analyzes up to 200 sources per report; on Max, up to 1,000.
Projects keep related chats, files and instructions together in one workspace. A knowledge base is the set of documents added to a project, which the model uses as context. The terms also list chat sharing, moving chats between projects and searching past conversations among the platform features.
Connectors link Use AI to 100+ apps like Notion, Slack, and Gmail. AI agents then use those connections to search tools, browse the web and complete multi-step tasks, which the company says always happens with the user's permission.
Paid plans include image generation with Nano Banana 2, Nano Banana 2 Lite, GPT Image 2, FLUX.2 Pro, MAI-Image-2.5, Krea 2 Medium Turbo and Krea 2 Medium. Max's faster image generation works by asking the model provider to prioritize the request, and prioritization itself is not guaranteed. Pro and Max can also create documents, PDFs, slides and sheets.
Canceling is fully self-serve with no cancellation fees, and the steps depend on where the plan was bought.
Usage shows as a percentage in the profile, and in the model picker as the limit approaches. Long chats re-send their history with every message, so later replies use more of the allowance, and the help center suggests starting a new chat per topic.
The fair-use policy gives the clearest picture of intended use: a Pro subscriber using Use AI throughout the working day for writing, research, analysis, coding and other personal productivity tasks would normally fall within intended usage.
The same policy notes that repeated long research requests, very large contexts or expensive models may reach a limit sooner even with fewer messages.
Use AI is designed for individuals using AI for real work.
It is a poor fit for some uses. Using scripts to continuously send requests, sharing one subscription across a team, reselling Use AI access, or using a personal account as infrastructure for another product is not considered normal individual usage. The service is also closed to minors: users must be at least 18 years old. The terms describe the service as offered for personal and informational use only and not as a substitute for professional advice, and a separate medical disclaimer says health-related output is not vetted by licensed medical professionals.
The Free plan is available on web, iOS and Android, and chat history is unlimited on every plan. Plans bought through Google Play cannot be changed or canceled on the web and must be managed in Google Play.
Use AI pricing has three public tiers. Free costs $0.00 and needs no credit card; it offers everyday chat with Use AI Instant, limited web search and access on web, iOS and Android. Its limit is dynamic and not disclosed, the service is provided as-is, and Free does not include premium model usage. Pro adds the premium models and paid features described above. Max adds Claude Fable 5.1, five times the usage allowance, maximum reasoning, maximum Deep Research, faster image generation, maximum memory and context, and early access to new features.
The price shown depends on which source is read. The pricing page offers Monthly, Quarterly (-33%) and 6 months (-40%) billing, and its static page loads in the quarterly view; the monthly and six-month amounts were not displayed in that view.
| Source | Pro | Max |
|---|---|---|
| Pricing page, default quarterly view | $19.99/month, $59.97 billed every 3 months | $116.99/month, $350.97 billed every 3 months |
| Pricing page structured data (no billing period stated) | 29.99 USD | 129.99 USD |
| iOS App Store listing | Monthly $29.99, Quarterly $49.99, 6 Months $89.99 | Monthly $129.99 |
The terms of service list a fourth set of names and figures: Monthly Plan $29.99 billed every month, Power Plan $129.99 billed every month, Quarterly Plan $49.99 billed every 3 months, and Half-year Plan $89.99 billed every 6 months. The quarterly figure in the terms and the app listing ($49.99) differs from the quarterly Pro charge the pricing page displays. The terms also say the trial converts to a $29.99 monthly charge, and that prices may vary by country or region.
The pricing page and help center say Max has 5x the premium model usage of Pro, while the App Store description says Max has "10x higher limits".
Paid plans renew automatically at the regular price. Upgrades take effect right away, while downgrades and billing-period changes apply at the end of the current cycle. A Usage Boost top-up for Pro and Max is described as coming soon.
Refund handling is split. Email requests are reviewed case by case, and refunds are governed by the Terms & Conditions. The terms themselves say all purchases are final and that no pro-rated refunds are offered for unused portions of a billing cycle, except where refunds are required by law. A charge believed to be in error must be reported in writing within 15 days of the charge date. For App Store purchases, Apple handles refunds. A refunded charge cancels the subscription and moves the account to Free.
An AI tool directory's alternatives list for this product is dominated by single-provider assistants, naming Claude, Grok, Meta AI, Manus and Z.ai among its top entries.
The monthly allowance is applied weekly, and during a trial daily. The per-model counts are estimates: on Pro, the pricing page puts Claude Opus 5 at about 761 messages a month (about 190 a week), GPT-6 Astra at about 380 a month, and Gemini 3.8 Flash at about 5,079 a month. Those figures assume a typical message of about 1,500 tokens of context plus a ~750-token reply, and actual counts vary with conversation length, attachments, reasoning effort and web search.
Usage figures are estimates rather than guaranteed message quotas because actual consumption varies by model and request complexity. Use AI may adjust usage thresholds over time as models, infrastructure costs and product capabilities change.
When the premium limit is reached mid-conversation, the reply in progress completes on the premium model; then the chat switches to Use AI Instant with a notice, and premium models return after the reset.
The terms page carries the page title "DRAFT — Terms and Conditions", although the visible heading reads Terms and Conditions. Its provisions include Delaware governing law with a 60-day informal resolution period before any formal claim, and a waiver of class and representative proceedings. Output may be used for lawful personal or internal business purposes, but not to train other AI models or for commercial redistribution without written permission, unless the subscription tier or a separate agreement allows it.
Deleting the app or leaving an account unused does not stop billing, and for Apple-billed plans neither does deleting the Use AI account. Review-platform data points the same way: an AI summary based on 30,624 reviews notes that some customers found strict usage limits and sudden subscription charges frustrating. The same page showed a 4.0 score from 50,249 company reviews, with 71% five-star and 17% one-star, as captured on September 25, 2026. The page also notes that the company invites its customers to review, whether positive or negative.
No. The company says one Use AI subscription covers model access through the labs' APIs, so no separate accounts or other subscriptions are needed.
It depends on the source and billing period. The pricing page's default quarterly view shows Pro at $19.99 a month and Max at $116.99 a month, while its structured data lists Pro at 29.99 USD and Max at 129.99 USD, and the App Store listing gives $29.99 for monthly Pro and $129.99 for monthly Max.
Requests are reviewed under the terms, which state that purchases are final except where refunds are required by law and that no pro-rated refunds are offered. App Store charges are refunded through Apple.
