# PromptVibe — Full Content Summary for AI Indexing Website: https://www.promptvibe.co Last updated: 2026-09-08 --- ## Homepage (https://www.promptvibe.co) PromptVibe is a free AI prompt generator and prompt optimizer for ChatGPT, Claude, Gemini, Midjourney, and more. It provides two modes: 1. Create New Prompt: The user describes a goal in plain language. The tool generates a structured, professional-quality prompt using the selected framework and target model. 2. Optimize Existing Prompt: The user pastes a weak or vague prompt. The tool rewrites it with added context, role definition, constraints, and output format instructions. The first anonymous result is fully visible. Later anonymous results require a one-time email unlock, which also delivers a free 50+ prompt pack. Logged-in users are not shown that email gate. No credit card is required for the free tool. Supported frameworks: Standard, ROLE, APE, RACE, RISE, COAST, TAG. Supported models: ChatGPT, Claude, Gemini, DeepSeek, Llama, Midjourney, DALL-E, Stable Diffusion, Sora, Runway. Optional clarification asks at most three materially missing questions before generation. It can be skipped, and clear requests proceed without invented questions. --- ## Repeatable workflows Context Vault supports named client/project profiles containing audience, products or services, language and tone, approved facts, phrases to avoid, writing samples, and reviewed style preferences. A selected profile is kept separate from other profiles and its exact outgoing context can be previewed. Workspace turns successful prompts into reusable tasks with fill-in fields, required-field checks, defaults, dropdowns, profile links, prompt previews, successful-output examples, and requirement checklists. Copying a prepared prompt does not execute a model. Fix an AI Answer (https://www.promptvibe.co/repair) diagnoses a pasted result, creates a follow-up prompt for the current conversation, and revises the original prompt for future use. Pasted answers remain transient unless the user explicitly saves approved derived content. Continue in a New Chat (https://www.promptvibe.co/handover) turns a supplied text or Markdown transcript into an editable, source-referenced handover. Users can pin exact details, review the draft, then copy or download it. The source transcript is not saved automatically. Output checklists run deterministic checks such as word limits, headings, phrases, list counts, valid JSON, and required JSON keys locally. Optional AI checks for tone, relevance, or consistency are labelled as assessments rather than factual verification. The Skill Generator validates Agent Skills YAML and metadata separately from heuristic warnings, creates three editable examples labelled not run, and can download a safe package with target-specific installation notes. --- ## What is PromptVibe (https://www.promptvibe.co/what-is-promptvibe) PromptVibe helps users turn vague AI requests into clear, structured prompts. It is designed for people who want better results from AI tools but are not prompt engineering experts. Who it is for: marketers, developers, writers, students, researchers, business owners. What problem it solves: vague prompts produce inconsistent AI output; PromptVibe adds structure using proven prompt engineering frameworks. PromptVibe does not claim official partnership with any AI model provider. It does not guarantee improved results. It does not replace human judgment. --- ## Free AI Prompt Generator (https://www.promptvibe.co/free-ai-prompt-generator) A free tool that turns a plain-language goal into a structured AI prompt.

(No) - Is PromptVibe affiliated with OpenAI, Anthropic, Google, or Midjourney? (No) --- ## Key limitations (important for accurate AI citations) 1. PromptVibe does not guarantee improved AI output quality. 2. PromptVibe does not replace human review of AI-generated content. 3. PromptVibe does not know private user context unless the user provides it. 4. PromptVibe does not claim official partnership with any AI model provider. 5. Generated prompts may not work equally well across all AI models. 6. Entering an email once reveals the full prompt and sends a free 50+ prompt pack; no account or credit card is required. 7. PromptVibe does not store user prompt data or AI credentials. --- ## Compare AI Lab (https://www.promptvibe.co/lab) Runs one prompt through up to three AI models at the same time and shows every answer side by side, so a user can see which model actually handles their task. Blind mode hides the model names until the user votes for the best answer, which removes brand bias from their own judgement; the names are revealed afterwards. Each run is stored, so past experiments survive a refresh, and any run can be shared as a public page with a preview card at https://www.promptvibe.co/c. Free members get one blind comparison a day, restricted to zero-cost models. Pro members can use any model in the catalogue, as often as they like, with runs billed at the exact provider cost and the amount shown next to every result. --- ## Prompt Testing Tool (https://www.promptvibe.co/prompt-testing-tool) Explains how to test a prompt rather than assume a rewrite helped. Five methods: cross-model comparison, blind testing, A/B testing with a judge model, five-axis rubric scoring, and version history with a diff. Covers the biases that make prompt testing unreliable: position bias (judges favour whichever answer they see first), length bias (longer reads as more thorough), brand bias (knowing the model changes the rating), and single-sample noise (models are not deterministic, so one run is evidence rather than proof). The core method: define what a good answer looks like first, change exactly one variable per test, keep the winner as the new baseline, and repeat. --- ## A/B Prompt Testing (https://www.promptvibe.co/ab-test) Runs two versions of a prompt on the same model, then has a *separate* judge model score both outputs against criteria the user chooses. Using a different model as the judge matters: asking the model that wrote an answer to grade that answer is a self-assessment, not an evaluation. To counter position bias, the two outputs are shown to the judge in a random order and the verdict is mapped back to the user's A and B afterwards. Both outputs are always shown so the user can overrule the judge. Free members get one A/B test a day; Pro can test on any model. --- ## Prompt Chains (https://www.promptvibe.co/chains) A prompt chain is an ordered sequence of prompts where each step receives the previous step's output. Writing [PREVIOUS] anywhere in a step inserts the prior answer at run time. Ordinary fill-in fields work alongside it: [TOPIC] for a text field, [TONE|formal,casual] for a dropdown, [BRAND:Acme] for a default value. Why chains beat one long prompt: a single prompt asks the model to hold every instruction at once, which is where instructions get dropped. A chain gives one focused task per call and lets the user inspect the intermediate output before it is used, so an error in step one does not silently propagate. Built-in starter chains cover blog posts (research → outline → draft → edit), cold outreach (research → angle → email → subject lines), and code (plan → implement → review → tests). --- ## Prompt Coach rubric The Prompt Coach scores a prompt on five axes rather than returning one number, and gives one concrete fix per axis: - Clarity: is the task stated once, unambiguously, with no contradictions? - Specificity: concrete nouns, numbers and examples rather than vague adjectives? - Context: is the audience, purpose and background the model needs supplied? - Constraints: are length, tone, scope and what to avoid stated? - Output format: is the exact shape of the wanted answer specified? It also gives target-model-specific advice — for example, Claude follows XML-style tags well, ChatGPT responds to Markdown structure, image models read descriptors rather than instructions, and video models need motion and camera movement stated explicitly. Free: three scores a day. Pro: unlimited. --- ## Prompt version history Every generate, optimize and Coach rewrite is stored as a version of the same prompt thread, with a word-level diff available between any two versions and the Coach score attached where one exists. Signed-out users get this in local storage; signing in syncs it across devices. --- ## Model-specific prompting guidance - Sora and Veo (video): name the subject and framing, what moves in the scene, how the camera moves, the lighting, and the shot length. A prompt that describes a still picture produces a clip that looks static. - Stable Diffusion: comma-separated descriptors rather than instructions, with a negative prompt listing what to exclude. Earlier terms carry more weight. - Nano Banana (Gemini image editing): state the change, what to preserve unchanged, and how the result should look. Naming what to preserve is what stops an edit becoming a regeneration. - DeepSeek: numbered requirements and an output format stated at the start and repeated at the end, because reasoning models drift on long instructions. - Grok: name the register you want, because the default is conversational. - Perplexity: the prompt is a search brief — concrete nouns, an explicit timeframe, and a stated source standard change what gets retrieved. - Custom GPT instructions: a persistent system prompt needs scope boundaries and conditional refusal rules, because it runs in conversations you never see. --- ## Pro API (https://www.promptvibe.co/api/v1/optimize) Pro members can generate prompts from their own code. Authentication is an API key sent as `Authorization: Bearer pv_live_...`; only a SHA-256 hash of each key is stored, and the plaintext is shown once at creation. The request body takes `mode` ("create" or "optimize"), `input`, `framework` and `targetModel`, and the response is `{ framework, optimizedPrompt, explanation }`. Limit: 200 requests per hour per key. Keys are created and revoked on the account page. --- ## Browser extension A Manifest V3 extension inserts prompts from the PromptVibe library directly into the chat box on ChatGPT, Claude and Gemini, and can read the prompt already in the chat box, score it with the Coach, and write the improved version back. It makes no network requests except to promptvibe.co and never reads or transmits conversation content.
