This week, AI labs gated their cyber models and rebuilt the plumbing under coding agents
November 1–7 brought no new general-purpose flagship from the big US labs. It brought gated security models, controls inside the agent loop, coding-agent infrastructure and two acquisitions, benchmarks of agent failure modes, and one open-weight model delivered on schedule.

A quick tour of Promptea
A real tour of the app: analyze a prompt, copy the optimized version, pick an AI, read the news, and explore benchmarks.
What Promptea is and how it works
In short: Promptea is a free web tool that reads your prompt, scores it from 0 to 100 on six criteria (clarity, context, constraints, output format, verifiability, safety), tells you what to fix and writes an improved version for the AI you pick: GPT, Claude, Gemini, Grok, Kimi, DeepSeek, Perplexity. Works in English and Spanish, no account needed.
What is Promptea?
Promptea is a prompt analyzer and optimizer. You paste a prompt, choose what it is for and which AI you will use, and Promptea returns a score, the specific problems it found, concrete recommendations and an optimized prompt you can copy.
Around the analyzer there are four more tools: Find the best AI for a task, AI Daily (one verified AI story every morning, with its sources), model benchmarks with source and date, and a library of guides, a glossary and per-model prompt templates.
How a prompt is scored
The score runs from 0 to 100 and combines six dimensions. It measures how well specified the prompt is, using fixed rules, so the same prompt always gets the same score.
- Clarity
- Is there a stated goal and enough words to say what is wanted? Very short or goal-less requests score low.
- Context
- Does the prompt include the material to work on (inputs), say who the answer is for (audience), or give examples?
- Constraints
- Are there explicit limits such as tone, length, timeframe, region or rules the answer must respect?
- Output format
- Does it say what shape the answer must have (list, table, JSON, steps), and what a good answer looks like?
- Verifiability
- Can the answer be checked? Success criteria, error details and reproduction steps count here; it weighs most for debugging and code.
- Safety
- Starts at 100 and drops for text that looks like a prompt injection, for contradictory instructions and for a language mismatch with the request.
How to analyze a prompt with Promptea
- Paste your prompt. Paste the prompt you want to improve in the box on this page or in the analyzer.
- Choose purpose and AI. Select what the prompt is for and the AI model you will use it with.
- Read the score and copy the result. Review the 0–100 score, the findings and the recommendations, then copy the optimized prompt or save it to your library.
Supported AIs and prompt types
Promptea optimizes prompts for 7 AI families and 25 current models. It does not run the models: it writes prompts that follow each provider's own prompting guidance. The model list was last verified against the providers' documentation on October 9, 2026.

Frequently asked questions
What is Promptea?
Promptea is a free web tool that analyzes a prompt, scores it from 0 to 100 on six criteria, lists what to fix and writes an optimized version for the AI model you choose. It also recommends which AI fits a task, publishes a verified AI news story every morning (AI Daily) and shows model benchmarks with their source and date.
Is Promptea free? Do I need an account?
Analyzing a prompt is free and does not require an account. The weekly newsletter is optional and only asks for an email address if you choose to subscribe.
How does Promptea score a prompt?
It applies fixed, deterministic rules to the text and combines six dimensions: clarity, context, constraints, output format, verifiability, safety. The weight of each dimension depends on the kind of task it detects, and the same prompt always gets the same score. No language model decides the score. The method is public on the methodology page.
Which AI models does Promptea support?
It writes prompts for GPT, Claude, Gemini, Grok, Kimi, DeepSeek, Perplexity, with 25 current models in its registry (verified against the providers' own documentation, last on October 9, 2026). Promptea optimizes prompts for these models; it does not run them.
What kinds of prompts can I analyze?
8 purposes: Text, Study, Code, Data/JSON, Image, Marketing, Translation, Summary. Beyond the purpose you pick, the engine detects 14 task types (for example debugging, data extraction or customer support) and adapts the rules to them.
Does Promptea store my prompts?
By default, telemetry stores only metadata (score, task type, target model, language, finding IDs), not the text of your prompt. Your prompt library lives in your own browser. Share cards carry numbers only, never the prompt. Details are in the privacy policy.
Does a high score guarantee a better answer?
No. The score measures how completely a prompt is specified (goal, context, limits, output format, checkability, safety). It does not run the prompt and it cannot predict the quality of a model's answer. Use it to find gaps, then test the prompt with your model.
