PromptOptimizer v1.0.0

SIDE PANEL · CHROME / EDGE / BRAVE / FIREFOX

Turn scattered notes into prompts with roles, constraints, and {{variables}}.

PromptOptimizer lives in your browser sidebar. Dictate or type a draft, pick a strategy, and the gateway returns a structured system prompt: role framing, numbered steps, guardrails, and detected variables. Test it in the sandbox, then save it to your library.

WORKFLOW

Draft, refine, ship

⌘↵ from the editor · Esc closes dialogs

01

Draft or dictate

Type into the buffer or press Dictate. Strategy chips (Reasoning, Code, Direct, JSON, Persona) decide the structure the model must follow.

02

Refine against the gateway

⌘↵ sends the draft to a Cloudflare Workers AI worker running Llama 3.3 70B. The reply is parsed as JSON: prompt, rationale, variables.

03

Test, then keep it

Fill {{variables}} in the sandbox and execute the prompt before reuse. Copy the result or save it to the library with tags.

SPEC

What is in the build

vanilla ES modules · zero UI framework

STRATEGIES

Five presets: Reasoning, Code, Direct, JSON, System Persona. Each injects a different directive into the system message before your draft.

DICTATION

Web Speech API streams the live transcript into the buffer as you speak. Recorded audio routes through Whisper at the gateway when native recognition is unavailable.

PREVIEW

Markdown renderer with headings, fenced code, tables, and {{variable}} pills. Raw toggle shows monospace source. Input is entity-escaped before parsing.

LIBRARY

Saved prompts with category filters, search, and tags. Ships with starter templates. Full JSON export and import for backups or sharing.

SANDBOX

Populate variables and execute the finished prompt against /api/test before you reuse it. Response renders in preview or raw mode.

LIMITS

15 requests / minute and 100 / day per IP, enforced in the worker with 429 and Retry-After. Quota counter shows in the top bar.

STORAGE

chrome.storage.local, browser.storage.local, or localStorage fallback. Nothing leaves the browser except the prompt text sent to the gateway.
