Language, appearance, parsing preferences, API keys, and your account & data.

Language & appearance

  • UI language: 中文 / English toggle, applies site-wide.
  • AI output language: Follow system / Force Chinese / Force English. Note: parsing an English PDF with Force Chinese translates the content into the database.
  • Theme: Light / Dark / Follow system.

Parsing model preference Pro

Under Settings → Parsing model preference, pick a model separately for literature reproduction / Smart Review / Quick Import. The dropdown shows a live per-run cost estimate, so you can save money or reach for a stronger model as needed.

API Key (BYOK)

Configure your own OpenAI / Anthropic / DeepSeek key under Settings → API access, encrypted at rest (AES-GCM).

BYOK is decoupled from your subscription tier: any tier can enable it. For example, PRO + BYOK = all of PRO's advanced features + service fee only. See the pricing page.

Setup steps

  1. Pick a provider (OpenAI / Anthropic / DeepSeek) and paste your API key.
  2. Fill in the model name — e.g. gpt-4o, claude-3-5-sonnet-latest, deepseek-chat. Leave blank to use each provider's default.
  3. Click "Test connection" to verify the key and model work — on success you'll see the model's actual reply.
  4. Click "Save & encrypt" to finish.

Using your model inside Vara

  • Per-conversation: the model picker at the bottom of the chat box shows a "My model (BYOK)" option. Select it and that conversation routes through your key without touching Vara quota.
  • Global default: flip the "Use my model for Vara AI by default" toggle in Settings → API access, and every in-app AI feature (chat, Q&A, correction, PDF parsing, quick import, etc.) defaults to your BYOK model.
  • Vision exception: image understanding (uploading photos for analysis) still uses Vara's built-in MiMo vision model, not BYOK, to keep image results reliable.
  • Billing: BYOK calls are billed directly by your API provider. Vara does not charge for them or count them against your quota.

Data safety

  • Danger zone: one click to delete your account and permanently erase your data. Triple confirmation prevents accidents (PIPL Article 47 compliance).
  • Recoverable deletes: deleted materials are soft-deleted — contact an admin to restore them.
