Product
Everything in one calm surface
A chat workspace with the essentials done properly — nothing to configure, nothing in the way.
Answers as they are written
Responses stream token by token. Stop a long answer at any time and keep what has been written so far.
Conversations that stay with you
Every chat is saved to your account. Reopen it from the history sidebar on any device and continue with full context.
You approve what is sent
Before your first message leaves, you confirm that your text goes to the selected model. Reset that choice whenever you like.
One Thundera account
Single sign-on across every Thundera product. No separate password, and your session carries over from the apps menu.
An allowance that follows your plan
Your plan sets a monthly AI allowance. When it runs out you are told plainly and can upgrade from the shared billing page.

Your conversation is saved. Open it again from the sidebar and carry on — recent messages are sent along as context.
The workspace
Focused by design
A history sidebar, one conversation, one composer — inside the same Thundera top bar and apps menu you know from every other product. Light and dark themes, phone to desktop.
Models
Six models, named for what they do
Served by the Thundera models gateway — the single source of models for every Thundera app. The list below is read live from it.
Fast
Low-latency answers for short tasks.
Smart
Balanced quality for writing and analysis.
Reasoning
Multi-step reasoning for hard problems. Slower.
Economy
The most economical model for simple questions.
Code
Code generation, review and refactoring.
Vision
Image-capable model.
Ecosystem
Built into Thundera, not bolted on
Single sign-on
Your Thundera session is validated by the central auth service. The AI workspace never stores your tokens in the browser.
Shared billing
Plans and invoices live in one place at auth.thundera.eu. One bill covers every product you use.
Models gateway
Every call goes through models.thundera.eu with per-app budgets and a full request log.
Apps menu
Jump to Whisper, EAM, PhotoMemory and the rest from the same bar.
Open documentation
Every endpoint of the workspace API is documented under /docs.
Pricing
Simple plans, one bill
Read live from the central plan catalogue, so it is always what you will be charged.

Questions
Is Thundera AI free?
There is a free plan. Plans, limits and prices are listed live from the central Thundera catalogue on this page, and your plan decides your monthly AI allowance.
Which models can I use?
Fast, Smart, Reasoning, Economy, Code and Vision. They are Thundera model aliases served by the Thundera models gateway, so the underlying provider can change without you changing anything.
Are my conversations private?
Conversations are stored in your Thundera account and only you can list or open them. Before the first message is sent you approve that your text goes to the selected model, and you can reset that approval in Settings.
Do I need a new account?
No. Thundera AI uses your Thundera account (single sign-on). If you are already signed in to another Thundera product you are signed in here too.
What happens when I reach my allowance?
The workspace tells you your monthly AI allowance is used up and links you to your plan. Nothing is charged silently.
Can I use it from my own code?
The workspace API is documented in the docs. For direct model access in your own projects, use the Thundera models gateway, which is OpenAI-compatible.
