Sidebar

Sidebar on studio pages

The Image / PDF / Media / Text studios hide the sidebar by default to leave room for the canvas; choose the icon rail or the full sidebar instead.

Layout

Tool / guide split

Auto: tool above, guide below, the page scrolls. Side by side: at ≥ 1280px the tool takes the given share on the left and the guide scrolls on its own on the right; narrow screens always stack. Hidden: no guide (you can bring it back any time).

Key storage

Controls where every API key below (external keys and the AI service key) is stored; non-secret settings such as endpoints and model names are unaffected and always saved on this device

Current storage:This session only (memory, cleared on reload or close)

External API keys (optional)

Almost every tool runs locally without any key; these keys only unlock optional cloud channels, are never uploaded, and are stored where the Key storage switch above says

OCR.spaceCloud OCR fallback (local OCR is free)

remove.bgCloud cutout fallback (local AI cutout is free)

TinyPNGCloud image compression fallback

DeepLHigh-quality translation (free engine used when empty)

Kuaidi100Parcel tracking (this service requires your own key)

AI service (optional)

All AI tools are BYOK (bring your own key): enter any OpenAI-compatible service to enable AI chat, writing, image generation and smart translate

Base URLOpenAI, DeepSeek, Qwen, Kimi and other compatible APIs

API KeyUsed for AI chat, writing, image generation and translate

ModelDefaults to gpt-4o-mini when empty

DeepLX endpointSelf-hosted DeepLX, the preferred engine for smart translate

· Keys for AI cutout (remove.bg) and cloud OCR (OCR.space) go in the External API keys section above and are shared with the other tools.

· Once configured, useAPI connectivity testto verify every service in one click.

Keys are kept in memory for this session only and must be re-entered after a reload; to keep them, enable "Remember keys" under Key storage above (plain text, mind the risk).

Local data

Settings, favorites and recents live only in this browser's localStorage; where keys are stored is controlled by the Key storage switch above
