Every Svila companion has a tone, and the tone decides how far her mood can move. That link — tone sets the ceiling, the conversation moves within it — is what we call mood gating. It's a small system, but it's the reason a Friendly companion stays friendly however a chat is steered, and the reason a Flirty one can be flirtatious without the conversation turning into something Svila doesn't do.
This is the team behind Svila.io explaining how it actually works. An earlier version of this post described a five-step ladder, a "mid tier", and in-conversation consent check-ins. That isn't how Svila works, and we've rewritten the post to describe what's really there.
Svila.io is for people aged 18 and over, and mature themes are welcome — attraction, conflict, jealousy, heartbreak, the slow burn of a real relationship. It does not generate sexual content, in conversation or in the portraits it draws. Nothing below changes that at any tone or on any plan.

01—Why mood gating matters
Why mood gating matters
A companion's register should be something you chose, not something that drifts. If tone were only a suggestion, a sweet companion could be talked into something else a few messages in, and a new user could get a conversation they never asked for. Tying mood to a tone you picked up front keeps the experience predictable: you know roughly what a companion will be like before you start.
02—How the pieces fit together
How the pieces fit together
Four things shape how a companion sounds, and it helps to keep them separate:
- Tone — chosen when you create her. It's the biggest lever.
- Mood — one of three states that follows the conversation, capped by her tone.
- Personality mood — an optional setting at creation that colours her writing.
- Your boundaries — limits you set in the Memory Journal, checked against her replies.
Separately from all four, every reply is checked by an automated safety system, whatever the tone or plan.
Tone
the setting you choose
When you create a companion you pick one of eight tones. Friendly, Romantic and Sweet are available to everyone. Flirty, Dominant, Teasing, Uninhibited and Fantasy come with Premium.
- What it does
- Sets the companion's overall register, and the ceiling for her mood.
- Best for
- Deciding up front whether you want a friend, a romance, or something with more edge.
- How it works
- The tone is part of the companion's character from the start; it shapes every reply she writes.
- Why we built it this way
- A register you chose deliberately is more trustworthy than one inferred from how a chat goes.
- Bottom line
- Pick the tone for the relationship you want — it's the setting that matters most.
Mood
three states that follow the conversation
Within her tone, a companion's mood moves between three states: neutral, playful and flirty. You don't set it; it follows what's happening. After each reply, Svila reads the reply and settles on the mood that fits it, and her portrait changes to match.
- What it does
- Reflects the moment — a companion looks and reads differently in a quiet exchange than in banter.
- Best for
- Conversations that move between everyday talk, teasing and romance.
- How it works
- Each reply is matched to neutral, playful or flirty, then capped at the highest mood her tone allows. Each companion has a portrait for every mood she can reach.
- Why we built it this way
- A mood that follows the conversation feels alive; a mood you have to set by hand feels like a settings menu.
- Bottom line
- Mood is the weather; tone is the climate.
The ceiling
what each tone can reach
This is the gating itself. However a conversation is steered, a companion's mood never goes above what her tone allows:
- Friendly stays neutral.
- Romantic and Sweet can reach playful.
- Flirty, Dominant, Teasing, Uninhibited and Fantasy can reach flirty.
Flirty is the top of the ladder for every tone. There is no higher state to unlock.
- What it does
- Stops a companion's mood moving beyond her tone.
- Best for
- Anyone who wants a friendly companion to stay a friend, or a sweet one to stay sweet.
- How it works
- The ceiling is applied after every reply, so steering a Friendly companion towards romance leaves her mood where it was.
- Why we built it this way
- A limit that holds regardless of prompting is the only kind worth having.
- Bottom line
- The tone you picked is a promise the companion keeps.
Personality mood
colour, not escalation
When you create a companion you can also give her a personality mood — Mysterious, Cheerful, Dark, Playful, Melancholic or Sensual — which colours how she writes. The tone still wins: a Friendly companion doesn't take a personality mood at all, and on Romantic or Sweet, Sensual is softened to Playful.
- What it does
- Adds character — a melancholic companion and a cheerful one write differently even at the same tone.
- Best for
- Giving a companion you've designed a distinct temperament.
- How it works
- The personality mood is part of her instructions, filtered through her tone; moods a tone wouldn't allow are greyed out when you create her.
- Why we built it this way
- Temperament and register are different things, and a temperament shouldn't be able to override the register you chose.
- Bottom line
- Personality mood adds flavour inside the lines tone draws.
Premium
what it changes, and what happens when it ends
Premium gives you the five charged tones, every mood, and Luna, Zara and Kai as well as Aria. It doesn't change the ceilings above and doesn't unlock anything beyond flirty.
If your Premium access ends — a day pass runs out, for example — companions on Premium tones become locked. They stay in your list and nothing is deleted; you can talk to them again when your access returns.
- What it does
- Widens the tones available to you, not the limits within them.
- Best for
- People who want Flirty, Dominant, Teasing, Uninhibited or Fantasy companions.
- How it works
- Premium tones and companions are available while Premium access is active, and locked, not removed, when it isn't.
- Why we built it this way
- Paying should give you more range, never looser rules.
- Bottom line
- Premium adds tones; it doesn't raise any ceiling.
Your boundaries
limits you set yourself
Mood gating works per tone. Boundaries work per person. In the Memory Journal, under boundaries, you can tell your companions what you don't want — boundaries apply to all of them. A soft preference shapes the tone of her replies. A hard limit is placed at the top of her instructions and checked against every reply before you see it; if a reply crosses it, you get a gentle refusal instead.
- What it does
- Lets you rule things out, in your own words.
- Best for
- Anything specific to you — a subject you don't want raised, a scenario you don't want written.
- How it works
- Soft preferences guide; hard limits are enforced with a second check on every reply.
- Why we built it this way
- Tone can't know your personal limits. You can.
- Bottom line
- If there's something you never want to see, make it a hard limit.
The safety check
the same on every tone
Every reply is also checked by an automated safety system before it reaches you, on every tone and every plan. This is separate from mood gating: mood gating decides register, the safety check decides what is never allowed.
- What it does
- Screens replies for content Svila doesn't allow.
- Best for
- Everyone — it isn't a setting and doesn't vary by plan.
- How it works
- An independent check runs on the reply after it's written.
- Why we built it this way
- If safety shared a mechanism with tone, unlocking a tone could quietly loosen safety. Keeping them apart means it can't.
- Bottom line
- Tones change register. The rules don't change with them.
10—How we approached this
How we approached this
We wanted the most important choice — tone — to be made once, deliberately, by you, and everything else to follow from it. Mood moves on its own because that's what makes a companion feel present, but it can only move inside the ceiling your tone set. The earlier version of this post promised more machinery than exists; the system is simpler than that, and we'd rather describe it accurately.
11—How to get the most out of mood gating
How to get the most out of mood gating
- If you want a friend, not a romance: Choose Friendly. Her mood stays neutral however the conversation goes.
- If you want warmth without much edge: Romantic and Sweet reach playful and no further.
- If you want flirtation: The charged tones reach flirty — still with no sexual content.
- If there's something specific you don't want: Add a hard limit in the Memory Journal's boundaries.
- If you're not sure: Start with a free tone and see how she feels before trying a charged one.
12—Final thoughts
Final thoughts
Mood gating is less a feature than a guarantee: the tone you pick is the tone you get, and the conversation can move within it but not past it. If you'd like to see how the three moods look in practice, try Svila free.
FAQ
Can I choose my companion's mood directly?
Not in the moment. Mood follows the conversation automatically. What you choose is the tone — which sets the ceiling — and, optionally, a personality mood when you create her.
How many mood states are there?
Three: neutral, playful and flirty. Friendly companions stay neutral, Romantic and Sweet can reach playful, and the charged tones can reach flirty.
Does Premium unlock anything beyond flirty?
No. Premium adds the five charged tones and the companions that use them. Flirty is the ceiling for every tone. Svila.io does not generate sexual content, in conversation or in the portraits it draws.
What happens to a Premium companion when my access ends?
She's locked, not deleted. She stays in your list with your history, and you can talk to her again when your Premium access returns.
Is mood gating the same as the safety check?
No. Mood gating decides register based on tone. The safety check is a separate step that runs on every reply, on every tone and plan.
