## 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

## Scribbr

Scribbr was built around a simple promise: help students submit work they feel confident about. The core of the service is human proofreading and editing, delivered by a hand-picked pool of academic editors who go through an in-house training programme before they are allowed to take orders. Documents are returned with tracked changes, in-text comments and a short personal letter explaining the reasoning behind the main edits.

Alongside the human service, Scribbr offers a growing library of AI writing tools. The Academic Check bundles together grammar and language review, citation checking, plagiarism scanning and AI-content detection into a single upload, which is convenient when you want one pass over an entire paper rather than juggling separate tools. Individual utilities such as the citation generator for APA, MLA, Chicago, AMA, IEEE and ACS, the paraphrasing tool and the text summarizer can be used on their own without paying for an edit.

The platform also maintains a large free knowledge base of academic writing guides that has become one of the more popular ways students discover the brand. Pricing depends heavily on document length, chosen turnaround time and add-on checks, so the practical way to get a number is to upload a file and select services in the order flow.

**Pricing & Plans:** Freemium model. Free tools include the citation generator, grammar checker and summarizer. Human proofreading and editing, the plagiarism checker, AI detector, AI proofreader and Academic Check are paid per document, with the final price depending on page count, delivery speed and any add-on checks such as structure or clarity review.

- **Human proofreading and editing:** A vetted academic editor reviews your paper within hours and returns tracked changes, comments and an explanation letter.
- **Plagiarism checker:** Scans your document against a large web and publication database to surface potentially unoriginal passages before submission.
- **AI detector and AI humanizer:** Flags text likely generated by large language models and offers a rewriting mode aimed at making AI-assisted drafts sound more natural.
- **Citation generator:** Creates and verifies references in APA, MLA, Chicago, AMA, IEEE and ACS styles from a URL, DOI or title search.
- **Academic Check bundle:** Runs grammar, citations, clarity, plagiarism and AI-detection checks in a single upload of the whole document.

**Strengths:** Combines human editors with AI tools rather than relying on one alone; Strong editorial vetting process and a large pool of academic specialists; Free citation generator and knowledge base are genuinely useful on their own; Transparent turnaround options starting from a few hours

**Limitations:** Paid services are priced per document, which adds up for long theses; AI detector verdicts can still be disputed by institutions; Some premium checks require you to buy them alongside an editing order
