Anyone switching between ChatGPT, Claude, and Perplexity notices one glaring UX difference in the left sidebar: ChatGPT and Claude summarize every new conversation into a clean topic title, while Perplexity leaves your raw first prompt verbatim.
ChatGPT and Claude run an asynchronous LLM summarization pass after your first message to generate a short sidebar title, whereas Perplexity.ai treats each thread like a traditional search query and displays your literal prompt text. Installing Auto-Rename for Perplexity brings ChatGPT/Claude-style 3–7 word semantic thread titles directly to Perplexity.ai automatically.
| Feature | ChatGPT | Claude | Perplexity.ai (Default) | Perplexity + Auto-Rename |
|---|---|---|---|---|
| Default Sidebar Title | AI-generated 3–6 word topic | AI-generated concise topic | Raw first prompt truncated | AI or offline 3–7 word topic |
| Uses Answer Context? | Yes | Yes | No (prompt string only) | Yes (question + first answer) |
| Custom Prefix Tags? | No | No | Manual edit only | Automatic (e.g. [Research]) |
| Regex Skip Rules? | No | No | N/A | Yes (per-line regex exclusions) |
| Choose Your Own Model? | Locked to OpenAI | Locked to Anthropic | N/A | 10 providers + local Ollama + offline |
Many vague prompts—such as pasting an unfamiliar error code, a DOI link, or asking "What causes this phenomenon?"—don’t contain the canonical name of the concept until the answer arrives. Because Auto-Rename for Perplexity waits for Perplexity’s first-turn SSE stream to emit COMPLETED and passes both the prompt and the opening answer excerpt to the title generator, even cryptic debugging pastes get crystal-clear titles like Linux io_uring Submission Queue Starvation.
Just like ChatGPT and Claude, once a thread has its topic title, subsequent follow-up questions inside that thread should not keep changing the title underneath you. Auto-Rename inspects last_backend_uuid and is_related_query on every request so follow-ups are ignored with zero overhead, and watches manual rename calls so your hand-edited titles always win.
