## Karla (now Prism)

Karla started life as an AI writing assistant aimed squarely at journalists. The idea was to take the messy inputs of reporting — interview notes, official documents, transcripts, press releases — and use a large language model to help shape them into a structured article draft, so that writers could focus on judgment and editing rather than typing out background material.

The product has since moved on. Visitors to the original getkarla.com address now see the message 'Karla is now Prism', followed by a redirect to PrismRun.ai. The company says it changed the name because it now focuses on building a protocol and platform to define and execute complex processes and actions with AI — a broader ambition than a single-purpose newsroom editor.

If what you wanted was the original journalism tool, the site directs you to Newsrun.ai, a newsletter and information services product that uses Prism under the hood. So the Karla brand itself is retired, but the underlying AI writing and process technology continues to be developed and sold under the Prism name.

**Pricing & Plans:** Karla was offered on a freemium basis before the rebrand. Pricing for the successor product, Prism, is not published on the redirect page, so current plans and costs should be confirmed on the PrismRun.ai site directly.

- **Turn raw source material into articles:** Paste notes, documents, transcripts or press material and let the AI reshape it into a coherent article draft.
- **Structured writing workflow:** An editor built around the way newsrooms work, so structure and flow matter as much as speed of drafting.
- **LLM-powered drafting:** The engine underneath was built as a large-language-model-based writing assistant rather than a simple summariser or rewriter.
- **Now evolved into the Prism platform:** The project has evolved into Prism, a platform for defining and executing complex AI processes, with journalism features maintained at Newsrun.ai.
- **Made for journalism and editorial teams:** It was designed for professionals who handle constant input from many sources and need to turn it into published output quickly.

**Strengths:** Purpose-built for newsroom and editorial workflows; LLM-based drafting that goes beyond simple summarisation; Turns scattered source material into a structured starting draft; Technology lives on and is actively developed under the Prism brand

**Limitations:** The Karla name no longer exists — the product is now branded Prism, which can confuse people looking for the original tool; Journalism-specific workflow features have been split off to a separate product, Newsrun.ai; New target audience (developers and process designers) means some original newsroom-oriented features may not map to every user's needs

## 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.
