## autocomplete

autocomplete takes the idea of code autocompletion from GitHub Copilot and applies it to everyday writing. Once installed, the extension watches the text fields you use on Gmail, Outlook and ChatGPT, and as soon as you pause it proposes the continuation of the sentence inline in grey text. Press your accept key and the suggestion becomes part of your draft; ignore it and it disappears.

The engine behind the suggestions is OpenAI's GPT-3.5, which the extension's own listing names as the language model. That keeps latency low enough for suggestions to feel immediate and makes the tool most useful for the short, repetitive messages that fill up a work day — confirmations, follow-ups, quick answers and prompt drafting.

It is a small, single-purpose utility rather than a full writing suite: there is no document editor, no long-form rewriting and no team workspace. The listing notes it is published by the owner of autocomplete.live, has a good record with no history of violations, and offers in-app purchases on top of the free install. Because the completion runs through OpenAI's API, you should expect your typed text to be sent for processing, and the extension's privacy disclosure does state that it handles personally identifiable information.

**Pricing & Plans:** Free to install from the Chrome Web Store, with optional in-app purchases. No card is required to add the extension.

- **Inline AI autocompletion:** As you type, the extension proposes the rest of your phrase in-line, so you accept rather than write it out.
- **Works inside Gmail, Outlook and ChatGPT:** Suggestions appear in the text boxes you already use for email and AI chat, with no separate editor to open.
- **Powered by GPT-3.5:** Completions are generated with OpenAI's GPT-3.5 model, which keeps suggestions fast and natural-sounding.
- **One-key accept flow:** Keep typing to dismiss a suggestion or hit the accept key to insert it, matching the Copilot-style habit many users already have.
- **Lightweight Chrome extension:** A small install of under a megabyte that sits quietly in the browser and activates only on the supported sites.

**Strengths:** Removes repetitive typing in the tools you already use every day; Feels familiar to anyone who has used GitHub Copilot; Very small download and quick to set up; Free to install with an optional paid upgrade

**Limitations:** Only supports Gmail, Outlook and ChatGPT rather than the whole web; Runs on GPT-3.5, so output quality trails newer models; Typed text is sent to OpenAI for processing, which matters for confidential content; Store listing shows a low overall rating and has not been updated since mid-2023

## 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.
