Persona.chat

Persona.chat turns your free DeepSeek, Claude, or ChatGPT chat into a one-click tool for anything you'd normally rehearse or research alone — practice a tough interview or a salary negotiation, structure your thinking on a stock before you decide, or get a fast map of an unfamiliar field. No API key, no subscription, no server of ours in the middle — it just rides your own login on whichever site you already use. Nothing you type ever leaves your browser. Every persona, world info entry, and background image lives only in your own local storage — we don't have a server, so there's nowhere for it to go. See our privacy policy for specifics. Purposeful personas — pick a role (Behavioral Interview Grill, Salary Negotiation Coach, Stock Research Structurer, New-Field Research Guide, and more) and it opens by asking exactly what it needs to know — your target role, your walk-away number, the ticker — instead of guessing. 100+ built-in personas in total, including lighter roleplay and companion moods (a late-night bar owner, an illogical talking cat) for when you just want to have fun — or write your own with a personality, scenario, example dialogue, and greeting. Already have cards from chub.ai or SillyTavern? Import them directly (PNG or JSON) instead of starting from scratch. World info — basically "a cheat sheet the character can glance at" — attach keyword-triggered lore (a backstory detail, a running joke, a plot fact). Tap "✨ Enrich" before sending and matching lore gets woven into your message automatically. Stay in character — an optional in-character reminder resurfaces every few messages to fight the model drifting out of persona over a long chat. Scenes — 12 hand-tuned CSS backgrounds across five moods, or upload your own photos — swap the whole atmosphere behind the chat in one click. Page tweaks — on DeepSeek, hide its "reasoning trace" block if you just want the answer. Bilingual — full English/Chinese UI and content, auto-detected from your browser language. Everything you type is still sent the normal way, by you, pressing Enter — Persona.chat only ever prepares the message; it never sends anything on its own. Add it free, pick a persona, and turn your next DeepSeek, Claude, or ChatGPT chat into exactly what you need it to be.
