Use AI
One subscription, 13+ premium AI models in a single chat app — switch between Claude, GPT, Gemini and Grok mid-conversation
If you're already paying for two or three AI subscriptions, Use AI is the consolidation play: Pro at $19.99/mo undercuts most pairs and adds seven image models plus Deep Research. Max at $116.99/mo only earns its keep if you run source-heavy research and want the two Max-only models, Claude Fable 5.1 and GPT-6 Astra. Check the per-model table before you commit — premium usage is metered, and the spread is wide: roughly 952 Claude Opus 5.5 messages a month on Pro versus about 4,761 on Max.

Skip Use AI if you need programmatic API access, team workspaces with permissions, or Claude Fable 5.1 and GPT-6 Astra on anything other than the $116.99/mo month-to-month Max tier — those two models never appear on Pro.
Premium models are capped per model, not as one pool — the pricing page lists roughly 666 GPT-5.5 messages a month on Pro against about 5,079 for Gemini 3.8 Flash, so a GPT-5.5-heavy month runs out long before a
Pro at $19.99/mo month-to-month (or $59.97 billed every three months) sits in the same band as a single ChatGPT or Claude subscription but replaces two or three of them, which is where the value maths works for solo professionals and creators. Max at $116.99/mo month-to-month (or $350.97 billed every three months) is priced for source-heavy researchers who need the 1,000-source Deep Research ceiling and the 5× Pro allowance. Teams needing shared seats and permissions will find cheaper per-seat

What people actually say about Use AI — is it worth it?
We ran a structured research pass across product reviews, community discussions, and post-purchase forum threads to surface the patterns vendors won't publish themselves. Below: the recurring strengths, the hidden costs people mention most, and the cohort that consistently regrets adopting this tool.

- +Claude, GPT, Gemini, Grok and others in one window with no tab-hopping
- +Pro at $19.99/mo is cheaper than paying for three separate provider subscriptions
- +33% quarterly and 40% six-monthly discounts give real savings for committed users
- +Free tier plus Use AI Instant means a capped session doesn't end the conversation
- +Deep Research up to 1,000 sources on Max and 200 on Pro is a genuinely strong ceiling
- −Cancellation is reportedly impossible in-app while upgrades work — trust-damaging
- −A wave of near-identical YouTube reviews pushed by affiliates is hurting credibility
- −Per-model weekly allowances and token spend are not clearly disclosed up front
- −No community evidence confirms context truly survives mid-conversation model switches
- −Support signals are weak — the cancellation complaint got no visible resolution
- • Per-model monthly allowances applied weekly on paid plans — heavy use can hit walls before the month ends
- • Trials enforce a daily allowance instead of a weekly one, which misleads on real capacity
- • Max-only models mean the pricing page headline roster is larger than what a Pro buyer actually gets
- • Cancellation on mobile reportedly requires going through Apple or Google, not the app

About Use AI
Use AI is a consumer AI assistant that bundles more than a dozen third-party language models behind one subscription, so you stop paying for separate ChatGPT, Claude, Gemini and Grok accounts. Everything happens in one window, and you can switch models mid-chat when one writes better and another reasons better on the same thread. The premium lineup on the pricing page runs Claude Opus 5.5, Claude Sonnet 5.5, GPT-5.6 Sol, GPT-5.5, GPT-5.4, Gemini 3.8 Flash, DeepSeek V4 Pro, Kimi K3, Kimi K2.6, Grok 4.7 and GLM 5.2, with Claude Fable 5.1 and GPT-6 Astra reserved for Max. New models land automatically as providers ship them. It goes past chat. Image generation covers 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. Deep Research pulls up to 200 sources on Pro and 1,000 on Max, and you can build documents, PDFs, slides and sheets without leaving the app. Projects, knowledge bases, AI agents and 100+ app connectors handle longer-running work. Delivery is Web, iOS and Android, with unlimited chat history on every tier. Pricing is monthly or discounted quarterly (33% off) and six-monthly (40% off): Pro is $19.99/mo month-to-month or $59.97 billed every three months; Max is $116.99/mo month-to-month or $350.97 billed every three months. A free tier gives everyday chat on Use AI Instant plus limited web search, and Use AI Instant never counts toward premium usage — so hitting a cap doesn't end your session. Use AI Inc. states it provides access to third-party AI models and is not affiliated with or endorsed by their providers. The closest alternatives are the provider subscriptions themselves — you trade depth in one ecosystem for breadth across many under one bill.
Behind the Verdict
The pitch is simple: stop juggling four subscriptions. Use AI aggregates the big-name models under one login, and mid-chat model switching is genuinely useful — start a thread on Claude Sonnet 5.5, hand the hard math to Claude Opus 5.5, draft the summary on Gemini 3.8 Flash. That beats copy-pasting between browser tabs. We'd reach for this when breadth matters more than depth. Content people mixing text and images, small operators who want one bill, anyone curious about Kimi or GLM without opening another account. The free tier is a real trial of the interface, and because Use AI Instant is unlimited on paid plans and never counts toward premium usage, running out of Claude messages doesn't leave you stranded — you keep working on the in-house model. Where it bites: metering. The provider page publishes per-model monthly estimates, and they vary by more than 5×. Gemini 3.8 Flash gives you roughly 5,079 messages a month on Pro; GPT-5.5 gives you about 666. Heavy Opus users should look at Max, where the same model buys around 4,761. Two limits you can't pay your way out of on Pro: Claude Fable 5.1 and GPT-6 Astra are Max-only. If either is your daily driver, Pro is the wrong tier. The closest alternative isn't another aggregator — it's just buying Claude Pro and ChatGPT Plus separately. That route gives you each vendor's own app, memory and roadmap, but two bills and two contexts. Use AI wins on breadth and price; the single-vendor subscriptions still win if you live inside one ecosystem. Developers should look elsewhere. There's no API or programmatic access documented here, and no shared workspace with permissions or role-based collaboration, so teams are better served elsewhere.

Real-world workflow fit
Concrete scenarios for the personas Use AI actually fits — and what changes day-one when you adopt it.
Paste a client brief into one thread, draft the positioning with Claude Sonnet 5.5, then ask GPT-5.6 Sol the same question and compare the two answers side by side before writing the deliverable.
Outcome: One subscription replaces two, and the client gets the stronger of two drafts rather than whichever model you happened to have open.
Brainstorm concepts with Use AI Instant so nothing is spent from the premium allowance, then generate campaign images in Nano Banana 2 and Krea 2 Medium in the same window to compare styles.
Outcome: Text and image work stay in one app with one file library, and the premium allowance is reserved for the parts that need a frontier model.
Run a Deep Research pass on Pro that pulls up to 200 sources, save the results into a Project knowledge base, then push the hardest analysis questions up to Maximum reasoning on Max.
Outcome: Source-heavy research and the final hard reasoning step both live in one workspace instead of being split across a research tool and a separate chatbot.
Use Cases
- Compare answers from GPT-5.6 Sol and Claude Opus 5.5 on the same research question without leaving the thread.
- Generate the same image with Nano Banana 2 and Krea 2 Medium to pick the style that fits a campaign.
- Run a Deep Research pass that pulls up to 200 sources on Pro, or up to 1,000 on Max, for a literature review.
- Draft a document, slide deck or spreadsheet in the same window you brainstormed it in.
- Switch models mid-chat when one writes better and another reasons better on the same problem.
- Keep a long-running client project organized with Projects and a knowledge base.
- Use connectors to pull context from Slack, Notion or Google Drive into a chat.
- Drop to Use AI Instant for long brainstorms so you don't spend premium usage you're saving for a hard problem.
Models Under the Hood
as of 2026-10-18
Limitations
- Premium model usage is metered per plan, with each plan including a monthly allowance for premium AI models that is applied weekly on paid plans; "unlimited messaging" applies to Use AI Instant, not premium models, and is subject to fair use.
- Claude Fable 5.1 and GPT-6 Astra are listed only on the Max plan, and the usage boost is shown as "Coming soon." Deep Research scales by tier — up to 200 sources on Pro and up to 1,000 on Max — while Free is limited to everyday chat, limited web search, a limited file library and low reasoning effort.
- Use AI Inc. states it provides access to third-party AI models and is not affiliated with or endorsed by their providers, and that AI can make mistakes.

Where the pricing makes sense
The company stage and team size where Use AI's pricing actually pencils out — and where peers do it cheaper.
Pro at $19.99/mo month-to-month (or $59.97 billed every three months) sits in the same band as a single ChatGPT or Claude subscription but replaces two or three of them, which is where the value maths works for solo professionals and creators. Max at $116.99/mo month-to-month (or $350.97 billed every three months) is priced for source-heavy researchers who need the 1,000-source Deep Research ceiling and the 5× Pro allowance. Teams needing shared seats and permissions will find cheaper per-seat
Setup time & first value
How long it actually takes to get something useful out of Use AI — broken out by persona, not the marketing-page minute.
Free tier: sign in and start chatting in minutes, no credit card required. Pro: checkout is immediate and mid-chat model switching works from the first thread, so most people see the value inside a single session. Max: same flow, but give yourself a week with the per-model usage table before you assume the 5× allowance covers your pattern.
Switching to or from Use AI
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From a standalone ChatGPT subscription: keep your ChatGPT account for now, sign in to Use AI and re-run your most common prompt against GPT-5.6 Sol and Claude Opus 5.5 before cancelling anything.
- →From separate Claude and Gemini subscriptions: consolidate reference material into a Use AI Project and knowledge base, then drop whichever single-model bill you use least.
- →From a ChatGPT Plus subscription plus a separate image tool: move image work to Nano Banana 2 and FLUX.2 Pro inside Use AI, and cancel the standalone generator once you've compared output.
- →From free-tier hopping between provider apps: start on Use AI Free, confirm the interface fits, then move to Pro at $19.99/mo month-to-month or $59.97 billed every three months.
- ↗To a single provider subscription: if the per-model message table shows you only ever hit one model, move to that provider's own plan and drop the breadth you aren't using.
- ↗To a developer API platform: if you need programmatic access rather than a chat app, this isn't the right shape and a direct provider API is the path.
- ↗To a team collaboration suite: if you need shared workspaces, permissions and role-based access, plan to leave before seats multiply.
- ↗To a specialist image generator: if image work dominates your usage and Deep Research never runs, a dedicated generator may cost less than a chat hub.
