Chat is the center of Babbily. You can ask questions, draft content, analyze files, research topics, create media, and continue work across a thread.

Model capabilities

Choose a model for speed, reasoning, files, tools, media, context, and API usage budget.

Canvas and artifacts

Create, edit, save, export, and send generated work from a dedicated Canvas.

Voice dictation

Prefer speaking to typing? Use voice dictation in chat or Translate when your device supports it.

​
Choose a model

Use the model picker to choose the model for a chat. Models can differ in:
  • Speed.
  • Reasoning depth.
  • Writing style.
  • Context window size.
  • File support.
  • Tool and media support.
If a tool or file type is hidden, the selected model may not support it. Switch models if you need a capability that is not available. Some models also show extra selector cues:
  • Fast mode means the selected model can use a faster response path for supported work.
  • Sunsetting means the model is still available, but Babbily recommends a newer option for new chats when one is available.
The September additions are Claude Fable 5.1, GLM 5.3 Flash, and Gemini 3.7 Flash. Some older models remain selectable as Sunsetting; others have been removed from the picker. See current model transitions and alternatives before continuing work with an older model.

​
Adjust reasoning

Choose Manual tool mode and turn on Reasoning. Models with adjustable effort show a Reasoning effort selector beside the microphone. Other reasoning-capable models offer an on/off toggle without a level selector. See reasoning controls by model for the September additions. Reasoning effort and Fast mode are separate controls.

​
Use Fast mode

Fast mode can be useful for drafting, brainstorming, coding, and iterative work where speed matters.
1

Select a supported model

Open the model picker and choose a model with the Fast mode lightning icon. Claude Opus 5 supports Fast mode.
2

Turn on Fast mode

Choose Fast mode using the lightning control near the composer.
3

Send your prompt

Babbily uses the faster response path while keeping your selected model visible in the chat.
Fast mode can use more of your API usage budget. Babbily turns it off when you change chats or select another model, so turn it on again when you still want the faster path.
The Fast mode control appears only for supported models. “Flash” in a model name does not mean it supports this toggle. Check Fast mode availability if the control is missing.

​
Write better prompts

Good prompts usually include:
  • The outcome you want.
  • The audience.
  • Any constraints or examples.
  • The format you want back.
  • Whether Babbily should use search, files, memory, or connected apps.

​
Continue a thread

Follow-up messages can refer to earlier replies, files, and context in the same thread. If a conversation gets long, Babbily tracks the context window and may compact older context so the thread can continue.

​
Get notified when a run finishes

For longer chats or research-heavy prompts, Babbily can notify you when a background run finishes. After your first prompt, Babbily may offer Get notified when Babbily is done. Choose Allow notifications if you want completion notifications, then allow notifications in your browser or device prompt. You can also turn Chat completion notifications on or off anytime in Settings > Account > Notifications.
Completion notifications are optional and depend on browser or device notification support.

​
Work in Canvas

When a reply becomes a document, table, code snippet, image brief, or structured output, Babbily may open it as a Canvas artifact. Canvas gives you a side workspace where you can edit, save versions, export files, and continue prompting with the latest artifact state included as context. Use Canvas when you want to refine generated work instead of copying it into another app first.

​
Use chat history

Saved chats appear in the sidebar and Library. You can reopen, rename, share, or delete chats from the available thread actions.

​
When to start a new thread

Start a new thread when:
  • You switch topics.
  • Earlier context is no longer useful.
  • The context indicator is near the limit.
  • You want a cleaner answer without old assumptions.
If Babbily keeps using old context, start a new thread and restate only the details that still matter.

Prompting patterns

Write clearer prompts with goals, context, audience, constraints, and output format.

Known limits

Understand what can vary by model, tool, file, plugin, plan, usage, and context.
