Canon voice: clipped, informal. Never smiles. Left-handed.

Where it stalls
Where drafts usually stop
- 01
Characters break
A character who never smiles in canon keeps smiling in chatbot prose. Readers spot OOC before anything else.
- 02
Canon and your AU blur together
Events you changed mix with the canon timeline until even you are unsure where canon ends.
- 03
Every ship needs its own voice
The same writer sounds different from work to work. A chatbot keeps drifting back to one tone.

- About voice matching
Voice matching per work

FAQ
Before you start
Can I upload the source text?
We recommend summaries and traits in the bible rather than full source text, which may raise rights issues. In any case, nothing you upload is used to train a model.
What about real-person fiction?
Sexual or defamatory requests about real people are refused by the AI. Fandom norms and platform policies are yours to check.
How do I separate canon from my AU?
Put canon events and your changes on the timeline card and tag the changes. The AI reads both and gives this work's canon priority.
Does the voice change per ship?
Style profiles are per work. Each work builds its own profile from its own pages, and profiles never mix.
Can I sell derivative work?
Commercial use of derivative work depends on the rights holder's policy. SparkLore is a tool; checking rights is your responsibility.

Honestly
This is not for you if
Plainly:
- Where the rights holder forbids derivative work or restricts commercial use, their policy wins. Checking is on you.
- Sexual or defamatory content about real people. The AI refuses, and repeated attempts may limit your account.
- Wanting the model trained on source text to write “like that author”. We train on nothing.
