Kopai Review (2026): Pricing, Features & Honest Verdict

What is Kopai?

Kopai lets you describe an agent in plain English, upload the documents that make it useful, test it, and publish it to a public marketplace with its own indexed page. Buyers pay per message. Kopai handles discovery, payments and infrastructure and takes 30%, leaving the creator 70 cents on every dollar. It launched on 1 August 2026 and finished eleventh on Product Hunt with 84 upvotes. The team is four people, with Surya Sekhar Datta, Swapnanil Ray and Meghna Bharadwaj named as co-founders.

The premise is the oldest one in the creator economy applied to agents: you know something specific and valuable, you have no way to sell it that does not involve consulting hours, and packaging it yourself means building a product you do not want to run. Kopai’s answer is that the packaging is now twenty minutes of writing instructions and dragging in PDFs. The founders are keen to say it is not a prompt wrapper, pointing at encrypted knowledge bases and multi-agent orchestration, and to their credit the feature list backs that up further than most launches in this category.

What is live gives a fair picture of the intended shape. The public marketplace currently features a study companion built from a university HCI course, a lead travel-planning agent that delegates to specialist subagents, a European immigration advisory agent covering programme matching and relocation logistics, and an Instagram analytics agent that reads saves, shares and watch time to explain why reach moved. Those are real expert niches rather than generic assistants, which is the correct early signal for a marketplace like this. There are only a handful of them, which is the other signal.

What are Kopai’s key features?

Agents built from your documents, with citations

You drop in PDFs, guides, manuals and FAQs, and Kopai chunks and indexes them. The demo shows an ISO 27001 document at 412 chunks, an internal controls doc at 88, an audit FAQ at 34. Every answer comes back with its sources attached, so a compliance agent quotes the clause and then names your own internal control that already covers it. Citation-by-default is the right call for the kind of agent people will pay for, because an expert agent that cannot show its work is worth nothing to the person relying on it.

Real files out, not just text

Ask for the report and you get an actual DOCX, XLSX or PDF the agent generated. Answers can also render live charts and tables in a sandbox. This is the feature that separates Kopai from a hosted chatbot, because the deliverable in most expert work is a document, and an agent that hands back three paragraphs of prose has moved the work rather than done it.

Model switching without a rewrite

You pick between GPT-5.2, Claude Opus 5, Gemini 3 Pro and others without touching your instructions. Useful for the obvious reason that model quality and price move every few months, and an agent locked to one provider is a liability. It also lets you tune cost against quality per agent rather than per platform.

Per-person long-term memory and embedding

Agents remember individual users across conversations, scoped per person, so a returning buyer does not re-explain their situation. And you can embed your agent on your own site with a single script tag, which the company frames as no lock-in. That last part is a genuinely confident move for a marketplace, since it means the tool remains useful even if the marketplace side never works out for you.

How much does Kopai cost?

Kopai is free to start with no card and no coding. The commercial term that matters is the split: creators earn 70% of revenue, Kopai takes 30%, metered per message and logged to a ledger with a visible payout schedule. Buyers pay per message rather than a monthly subscription, with the price set by the creator.

That 30% is the number to argue about. Gumroad takes around 10% to sell the same expertise as a PDF or a course. Apple and Google take 30% and are widely resented for it. Poe, the closest comparison, runs its own price-per-message creator model with points-based pricing for users and dollar payouts to creators, plus up to $20 per subscriber a creator brings in. Kopai is charging platform-store rates for a marketplace that does not yet have platform-store traffic, and that is the whole bet: the 30% is only defensible if Kopai’s discovery actually sends you buyers you could not have reached.

There is a second cost nobody is quoting. Agents run on GPT-5.2, Claude Opus 5 or Gemini 3 Pro, and inference on those models is not free. Kopai does not publish whether the model bill comes out of the platform’s 30%, the creator’s 70%, or the buyer’s per-message price, and the answer changes the economics completely. A document-heavy agent doing retrieval across 400 chunks and generating a formatted XLSX costs materially more to run than a short text reply, and until that is spelled out, no creator can price an agent with any confidence.

Who is Kopai best for?

Use Kopai if you have deep, documented, narrow expertise and no distribution. A compliance consultant with a shelf of ISO material, an immigration advisor, a course instructor with years of material: these are exactly the profiles on the marketplace now, and for them the 30% is a customer acquisition cost rather than a tax, because the alternative was zero customers.

Use it if you want to test whether your knowledge sells before building anything. Twenty minutes and a folder of PDFs is a cheap experiment, and the embed option means a working agent for your own site even if the marketplace side goes nowhere.

Skip Kopai if you already have an audience. If you have a newsletter, a following or an existing client list, you are handing over 30% of revenue for discovery you do not need, and Gumroad at roughly 10% or your own site with a Stripe link will keep far more of the money. Skip it too if you need to quote a client a fixed price, because per-message billing on a rate you do not control is not something most buyers will sign off.

What are the best Kopai alternatives?

Poe is the mature version of this exact model, with creator monetization via price per message, a points system for users, Stripe payouts once you clear $10, availability in 23 countries, and a subscriber-referral bonus of up to $20 per user. It has real traffic, which is the only thing that makes a marketplace worth 30%. It is also more constrained on document grounding and file output than Kopai, and creators have less control over presentation.

The OpenAI GPT Store is the largest audience by a distance and the most frustrating place to earn from. Distribution is unmatched, monetization has been repeatedly promised and thinly delivered, and you are building on a platform that competes with you. Free to publish, which for many creators is exactly what it is worth.

Gumroad is the unglamorous alternative that beats all of them on economics. Package the same expertise as a guide, template pack or course, keep roughly 90% of revenue, and own the customer relationship outright. No agent, no per-message revenue, no compounding value from a knowledge base. If your expertise fits in a document, this is still the better business.

Final verdict: is Kopai worth it?

The product is better than the launch position. Citations by default, real generated files, model switching, per-person memory and an embeddable widget add up to a serious agent builder, and it is free to try. If you want to find out whether anyone will pay for what you know, Kopai is the cheapest experiment available this month, and building your agent there costs you nothing but an afternoon.

The marketplace is the weak half, and the site does not quite admit it. The public listings number in the handful, with one of the featured agents carrying a single review, and the earnings figures shown on the homepage are interface mockups rather than reported results, including a payout date in November that sits oddly on a product launched in August. No price per message is published anywhere, so a buyer cannot budget and a creator cannot model revenue before signing up. Model costs sit inside that undisclosed price too, which means the margin on a Claude Opus 5 agent and a cheaper one are not remotely comparable and nobody outside Kopai can see the difference. And a marketplace whose entire justification for 30% is discovery has to prove the discovery works before the fee is fair.

Build on it, embed it on your own site, and treat any marketplace revenue as a bonus. Do not plan a business around the 70% until Kopai can show buyers arriving on their own.
