Character.AI Advanced tutorial

Advanced · step 1 of 7

Decompose and chain

1. Split a big job into steps with a clear output each.
2. Feed each step's output into the next.
3. Check the output between steps, not just at the end.

Why this step matters: Small steps with a checked output each fail visibly and early, instead of one big answer that is wrong somewhere.

Structured output

Ask for a fixed table or JSON so you can check and reuse it.

Return only JSON: [{"claim": "...", "source_url": "...", "quote": "...", "confidence": "high|medium|low"}]

A good result: only JSON, no text before or after it, one object per claim. Paste it into any JSON validator; if it doesn't parse, reply "Return valid JSON only" and run it again.

Why this step matters: A fixed format can be checked by eye or by code and reused without retyping.

Automation and agents

Four things shape a character's reply: its Attributes, training from conversations (e.g. star ratings), the user's Persona, and the current conversation's context (Character Guide).

Why this step matters: Automation repeats mistakes at scale, so you need to know exactly what is run and what is checked.

Failure modes to watch

• Characters drifting off-role when the user changes topic.
• Ratings slowly shifting behaviour.

Why this step matters: Knowing how it typically fails tells you where to look when you review its work.

Cost control

US App Store lists Character.AI+ ($9.99 and $94.99), Character.AI Lite ($4.99 and $2.49) and Charms packs; billing periods aren't stated, so check at checkout.

character.ai's support site blocked our checker, so we couldn't confirm limits.

Why this step matters: Paying for features you don't use is the most common waste. Knowing the limits first tells you if the free tier is enough.

Privacy and team rules

• Don't paste passwords, ID numbers, card numbers or other people's private details.
• Assume the company can read and keep your chats unless its official policy says otherwise.
• For health, money or legal decisions, confirm with a professional or an official source.
• Write down which data is allowed in which tool, and who approves paid plans.

Why this step matters: Anything you paste may be stored and read. Deciding what never goes in is easier than undoing a leak.

Build a 10-task test set

1. Collect 10 real tasks with known good answers.
2. Run them now and score each pass/fail.
3. Re-run them when the bot, model or your prompt changes.
4. Keep the prompt that wins, not the one that feels better.

Why this step matters: Without a fixed test set, 'better' just means 'felt better'. Scores let you compare prompts and models fairly.
