Modalities — Comet Wins

Modalities: Comet compared with Amazon Bedrock
Feature	Comet	Amazon Bedrock
Text Input	Yes, requires free plan. The sidecar assistant takes natural-language prompts for search, summaries, and page tasks.	Yes, requires plus plan. InvokeModel and Converse APIs accept text prompts across hosted FMs.
Image Upload / Vision	Unknown. Vision on the current page is plausible for an in-browser agent, but Comet help does not spell out image attach.	Partial. Multimodal models (e.g. Claude on Bedrock) accept images via the Converse API.
Image Generation	Unknown. Image models exist on Perplexity web for some plans; not documented as a Comet browser feature.	Partial. Titan Image and third-party image models are in the model catalog. Not a consumer DALL·E-style chat.
Voice Mode	Unknown. Launch copy mentioned voice on mobile; the current Comet product page does not document a voice loop.	Unknown. Speech models exist on Bedrock. A turnkey voice-chat loop was not checked this round.
Video Understanding	Unknown. Perplexity can transcribe attached video on the web app; Comet-specific video understanding is not documented.	Partial. Video-capable models may be hosted. Bedrock itself is an inference platform, not a YouTube chat product.
Video Generation	No. Not a video generation product.	No. Not a video generation product.
File Upload (PDF, DOCX)	Unknown. File attach is documented for Perplexity search, not as a Comet browser control.	Yes, requires plus plan. Knowledge Bases ingest documents (S3, etc.) for RAG.
Code Execution	Unknown. The marketing site shows the assistant building a webpage in the browser; that is not a documented code sandbox.	Partial. Agents can call tools and Lambdas. No first-party Python sandbox in chat.
Audio Input	Unknown. Audio-file input is not described in Comet setup or privacy help.	Partial. Speech models are listed. Bedrock is not a dedicated STT consumer app.
Canvas / Artifact Editor	Yes, requires free plan. The assistant sits in a sidecar beside the page you are browsing.	No. Console playground, not a consumer artifacts canvas.
Screen Sharing / Computer Use	Yes, requires free plan. The assistant is documented acting on the live page (forms, shopping, posting) rather than only summarizing.	No. No computer-use desktop product.

Memory & Context — Amazon Bedrock Wins

Memory & Context: Comet compared with Amazon Bedrock
Feature	Comet	Amazon Bedrock
Persistent Memory	Unknown. Max “Brain” memory is documented for Perplexity Computer, not as a Comet default.	Partial. Knowledge Bases and AgentCore session memory. You configure retention.
Large Context Window	Unknown. No token window is published for the Comet assistant.	Unknown. Depends on the foundation model you invoke. No single Bedrock window.
Custom Instructions	Unknown. A global assistant-instruction setting was not found in Comet help.	Yes, requires plus plan. Guardrails, system prompts, and agent instructions in the console/API.
Conversation History	Partial. Comet is a full browser with history (cleared in Incognito). Assistant thread history across devices is not documented.	Partial. AgentCore sessions persist within configured limits. Stateless per InvokeModel call.

Integrations — Amazon Bedrock Wins

Integrations: Comet compared with Amazon Bedrock

Developer — Amazon Bedrock Wins

Developer: Comet compared with Amazon Bedrock
Feature	Comet	Amazon Bedrock
Function Calling	Yes, requires free plan. The assistant is documented taking multi-step actions (shop, email, fill forms) rather than only answering.	Yes, requires plus plan. Bedrock Agents use tool/action groups for function calling.
Streaming Responses	Unknown. Token streaming in the sidecar is not called out in Comet help.	Yes, requires plus plan. InvokeModelWithResponseStream and Converse stream tokens.

Embeddings API	No. Not an embeddings API product.	Yes, requires plus plan. Titan Embeddings and Knowledge Base vector indexes.
Structured Output (JSON)	Unknown. JSON-schema guarantees are not documented for the Comet assistant.	Partial. Tool schemas and JSON mode depend on the model. Guardrails add structure.
