Payments are generally non-refundable after access is activated, including for disliked, inaccurate, or unsuitable responses. Cancellation stops future renewals; it does not request a refund. Your legal rights still apply. Read the billing and cancellation policy

Plan facts, refunds, and privacy
  • Agents provide AI-generated text assistance. They do not send messages, connect to your accounts, process uploaded files, or create finished media files.
  • Usage limits and service availability apply. Access does not promise unlimited use or guaranteed results.
  • Chat connection safeguard: 50 counted session openings per account, shared across Agents. The counter resets one hour after the last counted opening.
  • At the limit, another session opening is refused until the counter resets. An unsuccessful connection attempt can still count.
  • Opening a session is different from sending a message. This safeguard is not a message allowance. Usage and availability limits may also apply within a conversation.
  • The individual-Agent and all-Agent plans use the same account-wide connection safeguard. Opening an Agent chat requests a session; refreshing, opening another tab, or reconnecting can request another. Revising in an already connected conversation does not itself call this session-opening endpoint.
  • A refused opening does not add to the count or extend its reset. When the reset time is available, the workspace shows when to try opening the Agent again. The connection safeguard does not specify how many useful drafts or messages a subscription includes.
  • Manage future renewals in Account & Billing → Subscriptions. Cancellation and a refund are different actions.
  • Payments are generally non-refundable after access is activated, including for disliked, inaccurate, or unsuitable responses. Cancellation stops future renewals; it does not request a refund. Your legal rights still apply.
  • Your prompts and relevant context are sent to the enabled AI service to generate a response. Avoid confidential, regulated, highly sensitive, or unnecessary personal information. Retention and deletion depend on the service and provider; read the Privacy Policy before sharing work.
  • For billing or access help, email help@ai-gen.co. Include your account email, order number, Agent name, and a short description of the issue. Do not send passwords, payment-card details, or confidential prompts.
  • If a payment has already been taken but access is missing, review your existing order and contact support before buying again. Report duplicate charges or billing errors through the same route. Any remedy follows the billing policy and applicable law.

Preparing for software engineering interviews? Work through problems on arrays, trees, graphs, dynamic programming, and other common topics. Get hints when you’re stuck, compare solution approaches, and check time and space complexity. Leave with a walkthrough, improved code, and a set of edge cases to test in your chosen language.

What it writes

  • Step-by-step solution walkthrough
  • Time and space complexity analysis
  • Edge-case test list

How to use it

Include the full problem statement, input constraints, your language, and what you have tried. For code review, paste the complete function and one failing or uncertain test case.

This workspace provides text assistance.

What you bring

  • Problem statement and constraints
  • Preferred programming language
  • Your code or current approach
  • A programming language to practice in

A good fit for

  • Stuck on a medium-level array problem during interview prep
  • Reviewing tree traversal before a software engineering interview
  • Comparing approaches to a dynamic programming problem

Ways to start

A few requests this Agent can handle.

I’m stuck on Two Sum in Python. My nested-loop solution is O(n²); can you give me a hint toward a faster approach?

Explain how to detect a cycle in a linked list, then show a Java solution and its time and space complexity.

Here’s my JavaScript solution for merging intervals: sort by start, then combine overlaps. What edge cases am I missing?

What this Agent does not do

It does not carry out actions in other applications.

  • Live interview answers or cheating during assessments
  • Cannot run code or verify results in an execution environment
  • Code review depends on the snippets and constraints you paste

Before you subscribe

What am I buying?

Choose access to this named Agent or the all-Agent plan. The offers above show the current price, billing frequency, and exact scope. GPTs on ChatGPT and future Skills are separate.

What happens after payment?

Checkout creates or uses your Ai-GEN account. Once your payment is confirmed, you can start using your Agent. Open it from your order confirmation or account. Choose a starter task, add your inputs, and send your first request.

Can I cancel?

Yes. Manage cancellation under Account & Billing → Subscriptions. Review the status and cancellation details shown there before confirming.

What if the response is not right for me?

Payments are generally non-refundable after access is activated, including for disliked, inaccurate, or unsuitable responses. Cancellation stops future renewals; it does not request a refund. Your legal rights still apply. Read the billing and cancellation policy

Can I use the response in my work?

Use it as a draft to review and adapt. Verify calculations, facts, rights, and suitability before relying on it. Do not provide information you do not have permission to share.

Can I paste work or client information?

Your request and relevant context are sent to the enabled AI service to generate a response. Use placeholders and share only the minimum information you have permission to send. Avoid confidential, regulated, highly sensitive, or unnecessary personal information; removing names alone does not make restricted material suitable. Review the Privacy Policy before sharing work

What if I have paid but cannot open the Agent?

Sign in with the account used for the purchase and review your existing order in Account & Billing. Contact support with your account email, order number, Agent name, and a short description of the issue before buying again. Do not send passwords, payment-card details, or confidential prompts.
