Get started
Open Sign up and create an account using the available registration method. Complete onboarding to set up your profile and study interests. Use a recognizable display name without adding private contact information.
Email and password accounts are supported. Telegram sign-in depends on availability and configuration. Google sign-in may appear as “Coming soon”; a disabled button is not an active sign-in option.
You can browse public community content freely. Sign in when you wish to contribute, save questions, vote, and use features that require an account.
Use Home for the question feed, Explore to discover topics and resources, and Search to look for a particular subject or question. The For you feed uses your interests and a mix of community activity; Latest helps you find recent posts.
Questions and community replies
Open the question composer, select a suitable category and post format, and write a specific title. Explain the problem, show what you tried, and identify the step that confused you. Attach relevant material if needed, then review your post before publishing.
The app supports text, image, multiple-choice, and PDF posts. Choose the format that fits your material and follow the limits shown in the composer.
Reply to a question or continue a reply thread. Explain your reasoning and credit sources. The question author can mark a helpful answer as accepted. Acceptance indicates that it helped the author; it is not an independent accuracy check.
Use votes to express your assessment of a question, save questions to revisit them, and repost useful discussions. Find saved questions through the Saved feed or the Saved questions link on your profile. Avoid duplicate posting and coordinated vote manipulation.
Look for the deletion controls on content you own. Review the confirmation carefully: deleting a question also removes its replies, including replies contributed by other people.
Images and PDF resources
Use JPEG, PNG, or a still GIF, up to 10 MiB per image. Animated images are not supported. Images must pass validation and the safety check before they can be accepted.
A PDF post can contain one to three PDFs. Each file can be up to 10 MiB and 500 pages. Share only documents you are permitted to distribute.
Open the attachment to use the integrated PDF viewer. You can navigate pages, adjust zoom, and download the document. If a preview fails, check your connection and try opening the attachment again.
PDF posts currently skip automatic AI classification, question chat, and AI reply reviews. Ask the community about the document, or write a separate text question containing the specific passage or problem you are allowed to share.
Check the file type, size, and PDF page count. An image may also be blocked by the safety filter. If safety checks are temporarily unavailable, wait and try again. Renaming a file does not change its underlying format.
AI study help
Ask for a concept explanation, a worked example, feedback on your reasoning, or a practice problem. Include your learning level and the part you find difficult.
Personal AI conversations are associated with your account. Question chat is attached to a community question and has visibility controls managed by the question owner.
A question’s opening AI response remains visible to other visitors. Making question chat private restricts follow-up access to the owner; it does not hide the question, attachments, community replies, or opening AI response. Check visibility before sending a message.
Valley supports automatic question classification and AI reviews of eligible replies. Treat its assessments as suggestions to examine alongside the explanation and your study materials. An AI review can be wrong.
The automatic assistance filter can skip greetings, thank-you messages, and simple requests for links or notes. PDF posts also skip these AI features. A missing response can additionally result from temporary service issues or usage limits.
Skipping automatic assistance is separate from blocking inappropriate content. A friendly message does not need an AI answer to belong in a discussion.
No. Check calculations, sources, and explanations against reliable course materials. Ask follow-up questions when the reasoning is unclear. Use AI in ways permitted by your school or assessment rules.
Open Settings → Preferences → Long-term memory. You can choose whether to save study preferences, add a learning goal, and remove individual saved memories. Turning memory off deletes saved preferences; conversation history is handled separately.
Profile, preferences, and notifications
Open Settings → My profile to edit the available profile fields. Your public profile helps other learners understand your interests and contributions. Avoid adding information you do not want publicly visible.
Use the appearance controls under Settings → Preferences to toggle between Light and Dark themes, or use the footer theme switch buttons anytime.
Open the notification panel to review community updates and use the available read, dismiss, and preference controls. Telegram notifications require the relevant account connection and notification option to be enabled.
The list ranks eligible accounts by their combined questions and replies during the current calendar month, with tie-breakers. Read our dedicated Top Contributors page for the full explanation.
Account and security
Open Settings → Account & security and use Change password. Follow the verification requirements shown there. Keep your password and sign-in codes private.
Email password recovery and verification are not currently complete features. A recovery screen does not guarantee that a reset email will be delivered. If you previously linked an available alternative sign-in method, use that existing method; otherwise, recovery may require assistance from the team through a published contact channel.
Review Login activity in your account settings to see active sign-ins. Sign out when you finish using a shared device.
Open Settings → Account & security → Delete my profile completely. Complete the required identity verification and read the confirmation before proceeding.
Account deletion removes associated records, including your questions, replies, and personal AI conversations. Replies on your deleted questions are also removed. Uploaded-file cleanup may finish later. Copies that other people independently saved or shared cannot be recalled.
The Payment & verification section is currently a demo. It does not take payments or upload verification documents. Preview choices do not establish an active subscription or verified status.
Troubleshooting
Quick solutions to common notices and messages you might encounter in the app.
| What you see | What to do |
|---|---|
| “Please remove inappropriate language before posting.” | Review your wording and replace abusive or potentially flagged expressions with clear, respectful language. |
| An image safety warning | Choose a suitable educational image. Automated screening can make mistakes. |
| Safety checks unavailable | Wait and try again; the affected submission cannot pass until screening is available. |
| Too many requests | Pause before retrying. Repeated clicks can extend the problem. |
| Server busy or AI temporarily unavailable | Keep a copy of your unsent work and try again later. |
| An expired session | Sign in again, then retry the action. |
| An empty personalized feed | Explore other categories or switch to Latest while relevant activity grows. |
