Labs · Card Brief Bag
Can't write the card?
Bag the material.
Jot down who the character is, the world, the opening scene, your taste tags — as rough as you like, pasted excerpts welcome. Then pick an exit: send the bag to your Foreverse app and let the butler agent write the card by a full playbook, or copy a task brief (craft rules inlined) into any AI. This page never generates and never uploads on its own.
The brief bag
Everything is optional — jot down whatever you have. Rough is fine: whoever writes the card (the app's butler agent, or the AI you pick) fills the rest in by the card-writing playbook.
Identity, relationship to you, looks, history, abilities, taboos, anything you want kept. Plain words beat formal lore: “a stubborn art restorer with a callused hand who owes me a favor”.
What world this happens in: era, place, rules. One line is fine; modern-day needs no explaining — leave it empty.
Where scene one starts: where you two are right now, what the relationship is, what's happening. This field shapes the greeting.
The flavor you want: genre, pacing, hard limits — all fair game as tags.
Fanfic, lore docs, excerpts — paste whole passages. Used only to learn flavor and facts; the card never copies sentences.
Two ways out
No AI generation happens on this page — the bag just packs your material properly and hands it off.
Put something in the bag first — both exits light up once any field has content.
The butler agent in the app carries the full card-writing playbook (archetype choice, lived-in writing, greeting patterns, anti-slop lexicon) and starts writing the moment the bag arrives. Generation spends your app account's credits: signup grants 5,000, and one card typically uses a small slice of that.
No app, no problem: the task brief lays out your material plus the craft rules as one instruction block. Paste it into any long-form AI to get a chara_card_v3 JSON — then drop that file into our checkup tool.
Where the writing actually happens
This is the honest split behind the tool: web pages here run everything locally and never spend anyone's tokens, while the AI that writes cards lives in the Foreverse app — a butler agent that carries the same card-writing playbook our official cards go through (archetype choice, lived-in writing rules, five greeting patterns, a calibrated anti-slop lexicon, and a scoring gate). The bag is the bridge: it collects material the way card generators do, then hands it to that agent through the existing web-to-app cloud channel.
The task-brief exit exists so the bag is useful even without the app: the same material gets arranged into one instruction block with the playbook's non-negotiables inlined, targeting a chara_card_v3 JSON that any of our card tools can then check.
What it doesn't do
It doesn't generate anything on the page, by design — the free-tools rule here is zero inference cost and no visitor generation endpoints. It also can't promise the butler's output will be great on the first pass: generation quality depends on the model and the material; the diagnostics tools exist precisely to check the result.
The brief format (fv-card-brief) is ours: sending it to the app needs a Foreverse account, and older app versions that predate the format will show the brief in My Cloud without knowing how to hand it to the butler. The copy exit has no such dependency.
FAQ
Does this page write the card with AI?
No — and that's deliberate. Every tool on this site runs locally with nothing uploaded, so the page itself never calls a model. The bag packs your material properly and hands it to something that does write: the butler agent in the Foreverse app (it carries the full card-writing playbook — archetype choice, lived-in character writing, greeting patterns, anti-slop lexicon), or any AI you already use, via the copy-ready task brief.
What happens when I hit “Send to my app”?
The form is packed into a small versioned JSON (kind fv-card-brief), and pushed to your own account's cloud stash — the same channel our card tools use, after a light email sign-in. Your app shows a badge under “My Cloud”; open it and let the butler write the card from the material. Sending the identical brief twice never takes a second slot: the cloud matches by content and just resets the 30-day retention timer.
Does generating in the app cost money?
Card writing runs on your app account's credits. Signing up grants 5,000 bonus credits, and having the butler write one card typically uses a small slice of that. There's no separate charge for the brief itself — the bag and the transfer are free.
What's in the copied task brief?
One instruction block: your material laid out section by section, plus the craft rules our card playbook considers non-negotiable — concrete details over adjectives, a greeting that's a scene already in motion, never speaking for {{user}}, anti-slop phrase bans, example-dialogue turn-taking, creator-notes checklist. It asks the AI to output a chara_card_v3 JSON, which you can then drop into our Card Checkup or Card Workbench to verify.
How rough can the material be?
Very. Every field is optional; one line like “a stubborn art restorer who owes me a favor” is a valid brief. You can also paste whole passages of fanfic or lore docs into the reference zone — they're used to learn flavor and facts, with an explicit instruction not to copy sentences. The form auto-saves to this browser so a long paste survives a refresh.
