“AI chat tools” used to mean one thing: a chatbot. In 2026 the label covers very different products. Some let you compare models side by side, some answer questions, some run multi-step tasks for you, some build entire apps, and some just rent out the computing power underneath. Picking well starts with knowing which kind you’re looking at.
This guide sorts the tools people search for most, including Arena (formerly LMArena), Claude, Genspark, Emergent, Chutes and RedeepSeek, into those groups. It explains how each one charges and what to check before you hand over a prompt or a payment. Facts and prices come from each company’s own pages, checked on 27 October 2026, unless we say otherwise.
How we put this guide together
- Sources: each tool’s official website, pricing page and help documentation. Where a company’s pricing page couldn’t be read, we say so and label third-party figures clearly.
- Not done: we didn’t run paid benchmark tests or audit any company’s security. This is a guide to what each tool is and how it charges, not a performance ranking.
- Last checked: 27 October 2026. AI pricing changes often, so confirm on the official page before you pay.
The five kinds of AI chat tool
Most confusion disappears once you know what a tool is for. These are the five groups the products in this guide fall into:
| Type | What it does | Examples in this guide | How you usually pay |
|---|---|---|---|
| Model comparison arena | Shows you two AI answers side by side and lets you vote | Arena (formerly LMArena) | No paid plan advertised; prompts may be published |
| Chat assistant | Answers questions, writes and analyses, with one company’s models | Claude | Free tier plus monthly plans |
| Agent workspace | Runs multi-step tasks such as research reports or slide decks | Genspark | Monthly plans with credits |
| App builder | Turns a plain-English description into a working app | Emergent | Monthly plans with build credits |
| Model infrastructure | Runs open-source models for developers through an API | Chutes | Pay as you go, per token |
| Persona directory | Wraps chat in named “specialist” characters | RedeepSeek.com | One-off credit top-ups |
Arena (formerly LMArena): compare models before you commit
If you searched for “lmarena”, you’re looking for what is now called Arena. The project began as a research platform from UC Berkeley researchers, grew into a company and, on 28 January 2026, dropped the “LM” and moved to arena.ai. The old lmarena.ai address now redirects there.
Its best-known feature is the battle. You type a prompt, two anonymous models answer, and you vote for the better reply, call a tie or say neither was good. Only then are the model names revealed. Those votes feed a public leaderboard that ranks models by human preference rather than by automated tests.
- Battle modeTwo anonymous answers side by side. Your vote counts towards the leaderboard.
- Side-by-side chatYou pick two named models to compare. Useful, but it doesn’t affect rankings because the names are visible.
- Direct chatTalk to one chosen model, a handy way to try a model before paying for it elsewhere.
Treat it as a public space
According to Arena’s own description, prompts and votes are collected for research and may be published, and some data is shared with model providers. Arena says personal information isn’t shared, but don’t paste anything private, from client documents to passwords.
A leaderboard rank is a useful signal, not a verdict. It reflects what voters preferred on the prompts they happened to try, and researchers have questioned how evenly models are sampled. Use Arena to shortlist, then test the shortlisted models on your own real tasks.
Claude: a chat assistant with clear published plans
Claude is Anthropic’s assistant. It has one of the more transparent price lists in this group: a free tier, a $20 a month Pro plan ($17 a month if you pay $200 for the year), and Max plans at $100 and $200 a month for heavy users, according to Anthropic’s pricing page and help centre. Team seats start at $25 a month, or $20 a month billed annually.
Usage on paid plans resets every five hours, with weekly caps on top. For the full breakdown, including API prices and which plan suits which kind of user, see our Claude pricing guide. (If you searched for “Claude valores”, that guide covers prices too, with a short summary in Spanish.)
Genspark: an agent workspace for multi-step tasks
Genspark markets itself as a “super agent”. You give it a goal, such as a research summary, a slide deck or a spreadsheet, and it works through the steps, producing pages it calls Sparkpages. It suits people who want finished documents rather than a conversation.
We couldn’t read Genspark’s pricing page directly; it blocked our automated check, and parts of the pricing are behind a login. Third-party reviews such as eesel.ai’s pricing breakdown consistently report a free tier with daily credits, a Plus plan around $24.99 a month and a Pro plan around $249.99 a month, all metered in credits. Treat those as reported figures and confirm them on genspark.ai.
Credits deserve the most attention here. Reviewers report that a simple research page may use a few dozen credits, while generating video can use close to a thousand in one go, so the same plan can last a month or an afternoon depending on what you ask for. Some reviews also cite billing complaints on public review sites. Read recent reviews and the cancellation terms before you subscribe.
Emergent: build an app by describing it
Emergent calls itself “an AI-powered development platform that transforms your ideas into fully functional applications.” You describe what you want (a booking tool, a dashboard, a small online shop) and its agents write and deploy the code. Its FAQ states that you own the code it generates, and it connects to GitHub so you can take your project elsewhere.
| Plan | Monthly | Billed annually | Credits per month |
|---|---|---|---|
| Free | $0 | $0 | 10 |
| Standard | $20 | $17 a month | 100 |
| Pro | $200 | $167 a month | 750 |
| Business / Enterprise | Custom pricing (adds team workspaces, SSO and admin controls) | ||
App builders are impressive for prototypes and internal tools. Before you build something customers will rely on, check where the app is hosted, who can access its data, and what happens to your app if you stop paying.
Chutes: open-source models for developers
Chutes isn’t a chatbot you open in a browser tab. It describes itself as “the leading open-source, decentralized compute provider” for running open-source models in production. Developers send requests to its API and pay as they go, per token, from a prepaid balance with “no subscription or monthly commitment”. It also offers isolated “TEE” computing for workloads that need extra privacy.
For most readers, Chutes matters indirectly: some consumer chat apps run on infrastructure like this. If you’re a developer, compare its per-token rates for the specific model you need against other providers. Rates vary by model and change often, so check the live pricing rather than any figure quoted in an article.
RedeepSeek.com: a persona directory, not DeepSeek
RedeepSeek.com organises AI chat into named “specialists” for SEO, writing, coding and more, and sells one-off credit top-ups from $3 to $25. It isn’t the official DeepSeek, which is at deepseek.com, and its pages raised enough trust questions that we wrote a separate, detailed RedeepSeek.com review covering the pricing maths and the safety signals.
What about “AI Insights DualMedia”?
This phrase gets a lot of searches, and many websites describe it as an AI analytics product. We couldn’t find an official product page, company or pricing behind those descriptions. The most consistent explanation is that it refers to an AI news section on a site called DualMedia, rather than a tool you can sign up for. If a page asks you to pay for or download “AI Insights DualMedia” software, be cautious until you can identify who actually makes it.
How these tools charge, and what that means for you
The price on a plan card rarely tells the whole story. These are the four pricing models in this group, and the catch with each:
Predictable bills, but usage still has limits that reset on a schedule. Check what happens when you hit them.
Credits run out at very different speeds depending on the task. Ask how many credits your typical job uses.
You only pay for what you use, but heavy or careless use can add up. Set spending limits if they’re offered.
The fourth model, one-off credit packs (RedeepSeek), avoids a subscription but often leaves out key details such as credit expiry and cost per message. And “free” arenas are paid for differently: your prompts become research data.
Checklist: before you choose an AI chat tool
- Do I know which company runs it and where it’s based?
- Does it say which AI model is answering, or is that hidden?
- What happens to my prompts and files? Are they used for training, published or shared?
- How is usage measured, and what does a typical task cost in credits or tokens?
- Can I cancel easily, and are unused credits refunded or lost?
- Can I export my chats, documents or code if I leave?
Which tool for which job
Good matches
- Trying several models before paying: Arena
- Everyday writing, analysis and coding help: Claude
- Turning a goal into a report or deck: Genspark
- Prototyping an app without coding: Emergent
- Running open-source models in your own product: Chutes
Think twice
- Pasting private data into a public arena
- Committing to credit plans before testing your real tasks
- Shipping customer-facing apps without checking hosting and data terms
- Paying for tools whose operator you can’t identify
- Choosing on leaderboard rank alone
Our verdict
Bottom line
Start by deciding what you need: comparison, conversation, tasks done for you, an app or raw model access. Arena is the easiest way to compare models for free, as long as you treat it as public. Claude has the clearest published pricing of the assistants here. Genspark and Emergent can save hours, but their credit systems need watching. Chutes is for developers.
Whatever you choose, check who runs the tool, what happens to your data and how usage is counted before you pay. Prices in this guide were checked on 27 October 2026 and will change.
Common questions
What is LMArena?
LMArena was the name of a platform where you compare two anonymous AI models and vote for the better answer. On 28 January 2026 it was renamed Arena and moved to arena.ai; the old address redirects there.
Is LMArena (Arena) free to use?
Arena lets anyone try models in battle, side-by-side and direct chat modes, and it doesn't advertise a paid plan for this. The trade-off is that prompts and votes are collected for research and may be published, so don't share private information.
How does the Arena leaderboard work?
Votes from anonymous battles feed a public ranking based on which answers people preferred. Votes cast after model names are revealed, and chats in side-by-side or direct mode, don't count.
How much does Claude cost?
Claude has a free plan. Pro costs $20 a month, or $17 a month billed annually, and Max costs $100 or $200 a month. Team seats start at $25 a month ($20 billed annually). See our Claude pricing guide for details.
What is Genspark?
Genspark is an AI agent workspace that completes multi-step tasks such as research pages, slide decks and documents. It uses credits, and its pricing page is partly behind a login, so confirm current plans on genspark.ai.
What is Emergent AI?
Emergent (emergent.sh) is an AI app builder: you describe an app in plain English and its agents build it. It says you own the generated code. Plans range from free to $200 a month, plus custom business plans.
What is Chutes AI?
Chutes is a serverless, decentralised platform for running open-source AI models through an API. It's aimed at developers and bills per token from a prepaid balance, with no subscription.
Is RedeepSeek the same as DeepSeek?
No verified link exists. The official DeepSeek is at deepseek.com. RedeepSeek.com is a separate persona-based chat site, covered in our dedicated review.
What is AI Insights DualMedia?
We found no official product, company or pricing behind it. It most likely refers to an AI news section of a site called DualMedia. Be cautious with pages selling it as software.
