Description
A real AI agent in every browser tab. Reads, clicks, fills, compares — powered by your ChatGPT Plus or your own API keys. Sephir is a real AI agent in every browser tab — reading pages, clicking buttons, filling forms, comparing tabs, and running multi-step work end to end. It runs on the AI accounts you already pay for. Sign in with your ChatGPT Plus subscription (OAuth via Codex), or bring your own API key for Claude, Gemini, OpenAI, Mistral, or OpenRouter. No extra subscription on top of what you already have. == What it does == • Reads the page you're on — from the selection toolbar or the side panel. • Compares two tabs side by side ("compare @tab[a] and @tab[b]"). • Extracts structured data into JSON using a schema you provide. • Drives forms and pages — click, fill, type, navigate, wait for results — with a per-tool permission prompt the first time. • Summarizes YouTube videos with timestamps, transcript-aware. • Rewrites email in your tone using writing samples you pin. • Records a multi-step chat as a reusable workflow with {{variables}}. • Installs agent skills from the skills.sh / GitHub registry. • Exports any conversation to Markdown, JSON, or the clipboard. The audit timeline shows every tool call with its timestamp and arguments. == Privacy == Conversations, keys, and tokens stay in chrome.storage.local on your device. BYOK keys are encrypted at rest with a non-extractable key. BYOK requests go from your browser straight to the provider — we don't proxy them. No history sync by default. Anonymous usage telemetry is on by default and one switch in Settings turns it off; it counts events only, never prompts, page content, or the sites you visit. Full policy: https://sephir.app/privacy-policy == Pricing == The free tier with your own API key is unlimited. Sephir Pro Lifetime is $39 one-time for the first 500 seats — no monthly subscription, ever, and a 30-day refund. == Open development == Built in the open.
