ChatOTL is a private AI chat assistant. Ask it anything, search the web with sources, upload files and ask about them, generate images, and combine past chats so you don't have to explain everything again.

How is ChatOTL different from other AI chats?

Most AI chats start from an empty box every time. ChatOTL lets you combine a few past conversations into one new chat that already knows them, and it keeps your files, saved instructions, and history where you can find them.

Which AI model does ChatOTL use?

ChatOTL uses DeepSeek for chat and reasoning. You can choose between DeepSeek V4 Flash, DeepSeek Chat, and DeepSeek Reasoner depending on whether you want speed or more deliberate reasoning.

Can I ask about my own documents, PDFs, and photos?

Yes. Attach documents, PDFs, images, and text files and ask about them in plain language — a summary, a specific detail, or a comparison across a few files.

Is ChatOTL free to start?

Yes. The Free plan includes 10 AI messages per month with no credit card required, so you can try it before paying for anything.

Combine your chats

Every other AI chat forgets what you talked about yesterday. ChatOTL lets you pick a few past conversations and continue in one new chat that already knows them.

Vacation planning

Hotel research

Budget talk

Combine → one chat that remembers all three.

More than a blank chat box

Most AI chats start from nothing every single time.

In ChatOTL you can keep the useful stuff.

Add files you come back to, then bring them into any chat and just ask.

Upload it once. Use it again later.

Ask about your files

Drop in documents, PDFs, images, and supported text files and ask questions naturally.

Ask for a summary.
Find a specific detail buried in a document.
Compare information across files.
Turn reference material into something you can actually talk to.

ChatOTL reads what you attach — including PDFs and images — and answers from it.

Try it with a file

Keep useful files for later

One attachment is handy. Files you can reuse are better.

Save the things you keep coming back to — a lease, a manual, class notes, recipes, research, receipts, anything.

Bring them into a chat whenever you need them.

No giant copy-and-paste prompt required.

Fast answers, or careful ones

Pick quick replies for everyday questions, or switch to a slower, more careful mode when the answer really matters. You can change it mid-conversation.

Try another idea without losing this one

Ever get a good answer and want to try a completely different direction? Branch it.

Start an alternate path from an earlier message without deleting everything that came after it. Explore both directions and keep the original conversation intact.

No copying the entire conversation into another chat.
