## Perplexity

Perplexity is an AI-native answer engine and autonomous research platform designed to replace traditional keyword search and fragmented browser tab workflows. Instead of returning a ranked list of blue links, Perplexity interprets complex natural-language queries, crawls live web indexes, academic databases, financial filings, and social discussions in real time, and synthesizes direct, structured answers anchored by numbered inline citations. Beyond conversational search, the platform has evolved into a broader agentic ecosystem encompassing Perplexity Computer for autonomous multi-step tasks and the Comet AI browser assistant.

Under the hood, Perplexity orchestrates its proprietary web-grounded Sonar model family alongside frontier third-party reasoning models—allowing paid subscribers to route queries through Claude Opus 4 and Sonnet 4, OpenAI's o3-pro and GPT series, or Google's Gemini models, or run parallel evaluations via Model Council. Its Deep Research mode autonomously decomposes intricate questions, conducts dozens of iterative searches across hundreds of primary sources, and compiles exhaustive, exportable briefing reports in minutes. Users can also organize ongoing projects inside Perplexity Spaces, which fuse uploaded private documents (PDFs, CSVs, docs) with live web grounding and custom system instructions.

Perplexity serves an expansive audience ranging from students and journalists to equity analysts, legal researchers, and software engineers. Individual users can rely on the free tier for everyday fact-checking, step up to Perplexity Pro ($20/month) for daily deep research and model switching, or subscribe to Perplexity Max ($200/month) for uncapped high-compute agentic runs. Organizations adopt Enterprise Pro ($40/seat/month) and Enterprise Max ($325/seat/month) for SOC 2 compliance, zero data training guarantees, and internal knowledge connectors, while developers integrate real-time grounded citations into custom software via the Sonar REST API.

**Pricing & Plans:** Offers a permanent Free tier with unlimited Quick Searches, 3 Pro Searches per day, and 1 Deep Research query per month; Perplexity Pro costs $20/month ($200/year) and Perplexity Max costs $200/month ($2,000/year) for individuals. Team plans start at $40/seat/month ($400/seat/year) for Enterprise Pro and $325/seat/month for Enterprise Max, alongside usage-based Sonar API billing.

- **Deep Research Autonomous Reports:** Executes multi-step iterative web and document research across hundreds of sources, cross-checking facts and generating structured, citation-backed analytical reports that can be exported as PDFs or shared as interactive Perplexity Pages.
- **Multi-Model Routing & Model Council:** Lets Pro and Max subscribers switch dynamically between Perplexity's in-house Sonar models and top external models (including Claude 4, o3-pro, and Gemini) or compare multi-model reasoning outputs side by side.
- **Perplexity Spaces & Hybrid RAG:** Provides dedicated project workspaces where users upload local PDFs, spreadsheets, and text files, configure custom assistant instructions, and run queries that combine private document retrieval with live internet search.
- **Perplexity Computer & Comet Assistant:** Extends Perplexity from passive Q&A into agentic execution, turning high-level user requests into completed workflows, multi-tab browser actions, and automated data synthesis via the Comet ecosystem.
- **Sonar Web-Grounded Developer API:** Exposes Sonar, Sonar Pro, Sonar Reasoning Pro, and Sonar Deep Research over standard HTTP endpoints so developers can embed low-latency, live-cited web intelligence directly into third-party applications.

**Strengths:** Every generated statement links directly to numbered, verifiable web or document sources, drastically reducing ungrounded LLM hallucinations.; Deep Research mode delivers comprehensive, multi-page synthesis reports at a fraction of the time required for manual desk research.; Broad model optionality lets subscribers use Sonar, Claude, OpenAI, and Gemini models under a single $20/month subscription.; Focused search scopes (Academic, Finance, Web, Social) and Spaces allow clean separation between general browsing and domain-specific knowledge work.

**Limitations:** The Free tier is tightly restricted to 3 Pro Searches per day and just 1 Deep Research query per month with no manual model selection.; Power users requiring heavy agentic Computer runs or uncapped o3-pro/Opus-level research must jump from $20/month Pro to the steep $200/month Max tier.; Synthesized summaries can still inherit inaccuracies if underlying top-ranked web sources contain outdated or biased reporting.

## Unless Browser Assistant

The Unless browser assistant is the Chrome extension side of the UNLESS platform, which provides an AI platform for businesses to create and deploy AI agents in any channel. The extension is now listed on the Chrome Web Store as 'Unless team assistant' and is published by Rocket Launcher BV, the company behind unless.com.

The problem it solves is a practical one for support and customer-facing teams: most teams do not work in a single system. A question might arrive in your own dashboard, in your mail client, or in a separate CRM, and a native app for one tool cannot help you the moment you switch to another. The Unless extension operates across systems and websites as a universal assistant, with contextual awareness so it adapts to whatever environment you are in.

Setup happens in the Unless dashboard, where it connects to your organisational knowledge so it can answer questions about your products and processes. When a reply alone is not enough, AI Actions let the assistant perform the action on the customer's behalf or point you straight to the feature in another system you need. The listing notes it requires an account and is intended for team use, and the developer has disclosed that it does not collect or use your data.

**Pricing & Plans:** The extension is listed as freemium/free to install, but the team assistant requires an account and runs on the UNLESS commercial platform. Confirm seat pricing and plan limits at unless.com.

- **Universal assistant across any system:** Works across your dashboards, mail client, CRM and public websites, so the same assistant is available wherever a customer question lands.
- **Organisational knowledge answers:** After dashboard setup, it queries your organisational knowledge to give answers grounded in how your business actually works.
- **Contextual awareness:** Adapts to the site or system you are on so support stays consistent across every touchpoint your team uses.
- **AI Actions:** Lets the assistant take an action on the customer's behalf when an inquiry requires it, instead of just answering.
- **Team-focused and privacy-disclosed:** The listing describes an account-based assistant built for team use, and the developer states it does not collect or use your data.

**Strengths:** Works across any website, dashboard, CRM or mail client rather than being locked to one system; Grounded in your organisation's own knowledge after dashboard setup; AI Actions let it act on the customer's behalf, not just answer questions; Contextual awareness keeps support consistent across touchpoints

**Limitations:** Requires a paid Unless account and dashboard setup before it does anything useful; Focused on team/organisational knowledge, so it is not the right pick for casual personal browsing assistance; Value depends on your organisation having its knowledge sources properly connected
