v5.0.0

Current version

Meet the Media Studio, Voice Mode, and Connected Apps

Our biggest update since 4.0. Create pictures and videos in the new Media studio, get pictures right in your chats, talk to Lexika out loud on the web and desktop, and connect Higgsfield, Notion and PostHog to your workspace.

  • Media studio

    Turn a sentence into a picture or a video, bring a photo to life, and see what each model makes before you pick one.

  • Pictures right in chat

    Ask for a logo, a sketch or a change to your photo, and watch the picture appear right in the conversation.

  • Talk to Lexika

    Talk instead of typing. Ask for a search or a picture mid-call, and Lexika answers out loud while the full reply lands in your chat.

  • Connected apps

    Bring Higgsfield, Notion and PostHog into your workspace and use them right from chat.

  • Meet the Media studio, where you make pictures and videos from a simple description
  • Pick from dozens of models, like Kling, Wan, Grok Imagine, SOUL and Recraft, each shown with something it made

v4.1.0

A New Look, Three New Languages, and Support Inside the App

Lexika wears its new Signal Field identity, speaks Spanish, Japanese and Vietnamese, and gets a rebuilt pricing page, a model finder, in-app support tickets, and a long list of polish on every platform.

  • Lexika has a new look: the Signal Field identity brings a refreshed palette, animated avatars for people and workspaces, and a favicon that follows your theme
  • A rebuilt landing page with a story-driven demo of a real conversation, new sections for teams and organizations, and the latest from the blog
  • The pricing page is rebuilt as a plan ladder in the same design, and plan cards now say how many Brains and entries each plan includes
  • Start the free trial straight from a plan card when your account qualifies
  • Spanish, Japanese and Vietnamese join English and Arabic — the app, the Knowledge Center, this changelog, and the model and plan descriptions are all translated
  • Pick a violet surface palette in Settings, independently of light or dark mode
  • Choose a chat background in Settings — eight patterned grounds or a solid one
  • A model finder in the models gallery: answer three questions to get a recommendation, then use it in chat or open its spec — also reachable from the chat's model selector
  • Drag your favorite models to reorder them
  • Rebind any global keyboard shortcut from the Shortcuts tab in Settings
  • Download a code block straight from its header
  • Get help without leaving Lexika: open a support ticket from Settings, and every contact link now leads to the support page
  • A transactions page under Pricing lists your full purchase history
  • Usage in Settings can be viewed step by step or grouped by feature, with a total row
  • Choose a background for the Brain map — dots, a grid or a constellation
  • Smooth follow-scrolling while a reply streams can be switched off in Settings
  • Models that are temporarily down are marked unavailable, and a failed send explains itself in plain language
  • Streamed replies keep up with bursts, and the model selector remembers which rail you were on
  • Workspace invitations, folder moves and Brain links now update live across your devices
  • Lexika asks before deleting a conversation, a lab chat or an attachment, and Shift-click selects a range in the attachment picker
  • Laboratory chats start from starter cards, and the Agentic Research setup reads as one editable sentence
  • Members of a workspace no longer see Brain write controls they cannot use, and the sidebar hides Brains and Folders sections you cannot fill
  • Slash commands lead with the current chat's own commands, and a blocked composer control explains why instead of ignoring the tap
  • Drawers can be pulled closed from scrollable content, and a text selection wins over the sidebar swipe
  • Downgrading a plan explains what you would lose before it goes through
  • Coach marks stand down while a banner, the plan card or the mobile sidebar is up, then pick up where they left off
  • Fonts load faster now that the Latin faces are self-hosted, and loaders are refreshed across the app
  • Generated images render whole and can be downloaded
  • A Mermaid block keeps its reserved height after a failed render, and streaming keeps going when a comment follows the live turn
  • Right-to-left polish: mirrored text fields, inline code that stays in one piece, switches that stay in their track, and Arabic-script line heights
  • Safari joins Arabic letters while a reply streams, and the message clock stays on one line
  • Paying with a card already on file lands on the receipt instead of an empty page
