## eFiling.us

Court eFiling is repetitive, form-heavy work. A paralegal or attorney often re-enters the same information — case captions, party names, index numbers, document types — into a court portal that has already been typed in the pleading itself. eFiling.us targets exactly that duplication. It is a Chrome extension that reads the pleading with an AI model, extracts the fields the filing system needs, and then drives the court portal through a set of automation components.

The product is distributed through the Chrome Web Store and is published by eFiling.us Inc, a New York based company. It is currently scoped to the New York State Courts E-Filing System (NYSCEF), the state's electronic filing portal, and the extension runs on top of that site as an overlay rather than as a separate web app. Because the extension needs to act inside the court portal and read sensitive documents, it requests access to personally identifiable information, payment information, and authentication data, and the developer publishes a privacy disclosure covering that use.

The extension is offered with in-app purchases rather than a standing free plan, which fits a professional legal user who files regularly and values time over a per-seat consumer price. It is a young product with a small install base and a single rating, so it is best evaluated with a hands-on trial on real filings before being added to a firm's standard workflow.

**Pricing & Plans:** Offered as an in-app purchase Chrome extension rather than a free tool, with pricing handled inside the product; no public self-serve price list, and the vendor invites direct contact for custom arrangements. It has been categorised as contact-for-pricing.

- **AI pleading extraction:** An AI model reads uploaded pleadings and pulls out the case details, parties, and metadata needed to populate a court filing.
- **One-click eFiling automation:** Pre-built automation components carry the extracted data into the court eFiling portal so routine filings can be completed in seconds.
- **NYSCEF-ready:** Built for the New York State Courts E-Filing System (NYSCEF), matching that portal's forms, fields, and workflow.
- **Browser-native workflow:** Runs as a Chrome extension directly on the court eFiling site, so no separate dashboard or file transfer is required.
- **Complex case support:** Handles complex case documents as well as standard pleadings, aiming to reduce manual re-typing and form filling.

**Strengths:** Automates the repetitive data entry that surrounds court eFiling; AI extraction is tuned to pleadings rather than generic documents; Purpose-built for the NYSCEF portal instead of a generic form filler; Runs inside the browser on the court site, so there is no migration

**Limitations:** Currently limited to the New York State Courts E-Filing System (NYSCEF); Requires in-app purchases; no open free tier for heavy use; Very small user base, so community support and reviews are limited; Extension access to court and authentication data demands trust in a young vendor

## 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.
