The most useful way to think about tools in Rivya is not “which mini app should I open?”
The better question is:
is this task already clear enough that I want the first turn framed for me?
That is where tools actually help.
This is the decision-layer guide. If you want the stricter tools scope page about what is actually live in tools today, read Tools in Rivya.
The Fastest Decision Table
| If the task is... | Better first move | Why |
|---|---|---|
| still fuzzy or branching | plain Chat | you still need exploration, not a fixed frame |
| quantitative and answer-shaped | AI Calculator | the task already wants a clean calculation structure |
| explanation-heavy and logic-shaped | AI Solver | the task needs a worked path, not only a conclusion |
That is the real split. The page layout matters less than whether the first answer already has a recognizable shape.
Tools Are Best When The Task Already Has A Shape
When the task is already narrow, a tool saves you from building the first turn from scratch.
That is because the live tools in Rivya do a few things up front:
- pick a default model
- load a task-focused instruction layer
- offer starter prompts
- narrow the expected answer format
That is a better start than blank chat when the job already has a recognizable shape.
Right now, the live tool set is still:
- AI Calculator
- AI Solver

Plain Chat Is Better When The Task Is Still Open
Go straight into plain chat when:
- the request is still fuzzy
- you are still working out what the real problem is
- the task may branch into several different directions
- you want open-ended exploration before locking the frame
In that case, the better path is usually /chat on the public pages or /studio/chat/[modelSlug] once you want saved context.
Example First Prompts
These prompts are examples of starting shape. They are not benchmark tests.
Plain chat example
I have three messy ideas for a product launch. Help me decide whether the first task should be a calculator, a solver-style explanation, or a normal chat workflow.AI Calculator example
Compare three pricing scenarios for a subscription product at 2%, 4%, and 6% monthly churn, assuming CAC is $42 and ARPU is $18.AI Solver example
Solve this step by step and explain why each step is valid: If 3x + 5 = 20, what is x, and how would you check the answer?The difference is visible immediately: one prompt is still exploratory, one wants quantitative structure, and one wants a worked explanation.
AI Calculator Is For Quantitative Work
Use AI Calculator when the task is mainly about:
- formulas
- conversions
- percentages
- scenario math
- rough business math
The point is not that it behaves like a keypad.
The point is that it frames the response like a quantitative workspace:
- answer first
- visible working
- clearer substitutions
- less irrelevant detour
If your real frustration is “I keep getting chatty answers instead of clean math,” Calculator is usually the better first move.
AI Solver Is For Worked Explanations
Use AI Solver when the task needs:
- a worked solution
- a structured explanation
- a step-by-step reasoning path
- an answer that teaches, not just concludes
Solver is the better fit when the user wants both the conclusion and the logic behind it.
If the task is not mainly quantitative, but still needs explanation and structure, Solver is often the better public start.
Tools Start Publicly, But The Work Still Lives In Chat
This is the key thing to keep in mind.
Tools do not create a separate project universe.
They still belong to the broader chat side of the product, which means they share:
- account context
- wallet logic
- chat history
- later continuation in Studio
That is why a tool session can begin on a public task page and keep growing inside saved chat later.
The practical version is simple:
- tools help you start cleanly
- chat helps you continue once the work stops fitting the first frame
The Most Common Mistakes
The common mistakes are:
- opening a tool before the task is really formed
- staying in plain chat long after the job is obviously math- or explanation-shaped
- treating “coming soon” like “already available”
The wider catalog structure is useful, but it is not the same as shipped capability.
A Clean Tool Flow
If the job is already narrow, this is usually the cleanest path:
- open Tools or go straight to the tool page you need
- choose AI Calculator or AI Solver
- sign in when you are ready to actually run and keep the work
- continue in the matching chat flow if the task grows beyond the first frame
That is the tools layer at its best: not bigger than it is, but much cleaner than starting from a blank chat box.

Prepare A Tool-Sized Question
Rivya tools work best when the question is already shaped enough for a focused answer.
Before opening AI Calculator or AI Solver, write:
- the exact problem
- the known values or givens
- the unit, format, or explanation level you need back
- whether you want an answer first, a worked explanation, or both
- what you will do with the result after checking it
If you cannot write those details yet, plain chat may still be the better starting point because the job is not tool-shaped enough.
Know When To Return To Chat
A tool result is useful when it makes the next step clearer. It should not trap the whole project inside a narrow form.
Return to Chat when:
- the answer raises a broader planning question
- the math result needs to become a business decision
- the solved problem needs explanation, rewriting, or follow-up context
- the work is no longer a single calculation or single worked solution
That is the practical split: tools give a cleaner first answer for narrow jobs, and Chat carries the surrounding context once the job grows.
