## 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

## ZeroGPT

ZeroGPT is best known as an AI content detector, but the site has expanded into a full writing and verification toolkit. The core AI/GPT detector lets you paste text or upload a file and returns a highlighted analysis showing which sentences look machine-written, with a percentage gauge and an automatically generated PDF report you can use as documentation.

Around that core sit several companion detectors and writers. The AI image detector and AI video detector extend checking beyond text; the plagiarism checker scans against billions of sources; and the AI humanizer and paraphraser rewrite text into a more natural style. A grammar checker, summarizer, translator, dictionary, word counter, citation generator, and AI email helper round out day-to-day writing tasks. The company says its multi-stage DeepAnalyse model is trained on internet text, educational datasets, and proprietary synthetic AI datasets, covers over 35 LLM families, and reports 98.4% detection accuracy with a false positive rate under 1%.

Access is freemium: the main tools work free in the browser, with MAX and EXPERT subscriptions for heavier use and premium features, and a separate API for organizations that need large-scale integration. ZeroGPT also runs on WhatsApp and Telegram through a bot, letting you chat, detect AI text, summarize, paraphrase, translate, and check grammar without leaving the messaging app.

**Pricing & Plans:** Freemium with paid tiers. Core tools such as the AI detector, summarizer, and grammar checker are usable free in the browser, while MAX and EXPERT subscriptions unlock higher limits and premium features, and API access is sold separately for organizations.

- **AI and ChatGPT detection:** Paste up to 15,000 characters or upload a file and get a highlighted breakdown of which sentences appear AI-written, plus an overall percentage score and a downloadable PDF report.
- **AI image and video detection:** Beyond text, ZeroGPT offers an AI image detector and an AI video detector that performs frame-level analysis to flag generated or manipulated visuals.
- **Plagiarism checking and humanizing:** Compare your text against billions of sources through the plagiarism checker, or rewrite and humanize AI text with the paraphraser and AI humanizer while keeping the original meaning.
- **Writing and productivity tools:** A bundled writing suite covers summarization, grammar and spelling correction, translation across many languages, a dictionary, word and character counting, citation generation, and an AI email writer.
- **API for organizations:** A documented REST API exposes detection, plagiarism, paraphrasing, summarization, grammar, chatbot, and translation endpoints for organizations that need to embed ZeroGPT at scale.

**Strengths:** Free browser access to the core AI detector, summarizer, and grammar checker; Sentence-level highlighting with an overall percentage and exportable PDF reports; Extends beyond text to AI image and video detection, plus plagiarism checking; Broad companion toolkit: humanizer, paraphraser, translator, dictionary, citations, email helper

**Limitations:** AI detectors can produce false positives, so results should be treated as a signal rather than proof; The strongest features sit behind MAX/EXPERT paid tiers and API access is a separate purchase; Character limits apply to the free detection box; No detection tool can guarantee correctness across every model and language
