Utility characters
Twenty-two of SognoAI's characters are tools rather than personas. Four are file analyzers — Image, PDF, Audio and Video — that read what you upload and answer questions about it. The rest identify things, name things, or build things: Crystal Identifier, Personal Style Finder, Ship Name Generator, OC Name Generator, and a set of fandom-specific OC makers.
They work like any other chat, which is the point: you upload or describe, you get an answer, and then you can argue with the answer instead of running the tool again.
Image Analyzer takes a photo, screenshot, artwork or diagram and gives you the whole frame first, then the detail you asked about, then what it probably means — and it says what is visible versus what it is inferring.
PDF Analyzer reads contracts, policies, reports, papers and manuals. It quotes the section before explaining it, then says what that means in practice and what is unusual about it. Audio Analyzer handles meeting recordings, voice memos, lectures and interviews: decisions, owners, deadlines, the exact quote and roughly when it was said. Video Analyzer walks a clip, screen recording or practice video back beat by beat — what happened, in what order, roughly when — then gives one cause and one fix.
All four keep the file in context, so follow-up questions build on the last answer rather than starting over.
Crystal Identifier takes a photograph of a rock, crystal or mineral and returns an identification with an honest confidence level — a daylight shot, a couple of angles and something for scale materially improve it, and it will tell you when it is not sure rather than guessing confidently.
Personal Style Finder works without an upload at all: six to eight questions about what you actually wear, then your style archetype named and explained. Ship Name Generator blends two names into something that sounds like a word, returning eight to twelve options sorted from smoothest to funniest.
The largest group here is character creation. OC Name Generator takes a one-sentence description and returns twenty names with their reasoning, sorted into grounded, invented, high fantasy and nickname-first. Character Design Ideas Generator returns a silhouette described in words, a shape-language rule, a three-colour palette with rough proportions, and a costume.
Then the fandom-specific makers: Demon Slayer OC Maker (breathing styles with named forms, nichirin blade colour, haori pattern), JJK OC Maker (a cursed technique with an exact rule and a binding vow that costs something), MHA OC Maker (a quirk with a real drawback), TADC OC Maker (the human who logged in and the cartoon the circus made of them), plus Sonic, Helluva Boss, Murder Drones, Dandy's World, Spidersona and Fursona makers.
There is no separate tool UI. Open the character, upload your file or describe what you want, and the first reply is the analysis.
The file and everything already said stay in context. That is the difference from a one-shot tool: the second question is usually the one that matters.
A generated character sheet can go straight into SognoAI's character creator, and image generation runs inside the same chat if you want a portrait of the result.
