SprintBrain

AI prompt library and text expander. Free team sharing, dynamic snippets with live formulas, and two-way Notion sync.

Text Snippets + AI Prompt Library in One Extension! Snippets and prompts that expand wherever you type. One library, synced across Chrome and mobile. Stress the model, not yourself. Every day you retype the same messages, recalculate the same numbers, and rewrite the same AI prompts. SprintBrain replaces all of that with two tools in one extension: instant text expansion and a reusable prompt library, both working in any text field across the web. ⚡ SNIPPETS & PROMPTS: TYPE ONCE, USE EVERYWHERE Save any text as a snippet and expand it with a short trigger. Type ::quote and your full pricing template appears. Type ::followup and your follow-up message is ready. It works wherever you can type — email, chat, documents, and web forms — with no copy-paste and no switching tabs. ✦ Type ::shortcut + Tab and the snippet expands instantly ✦ Live formula engine — prices, discounts, and totals calculate automatically as the snippet expands ✦ Multi-language support — store variants of one template and pick the language with a single click ✦ Dynamic placeholders — snippets with fill-in fields open a quick form before expanding ✦ Right-click any text field to browse and insert from the context menu 🤖 PROMPTS: YOUR REUSABLE AI BRAIN Stop rewriting the same AI prompts. SprintBrain gives you a searchable prompt library that lives next to your snippets and inserts into any AI chat interface. Press """ to open the prompt picker, type to filter, and press Enter — your prompt drops into the field, ready to run. No more digging through old documents to find the prompt that worked last week. ✦ """ opens your full prompt library instantly ✦ Built-in starter prompts: formal tone, casual tone, translate, summarize, expand, and bulletize ✦ Add your own prompts in the dashboard and they sync to the picker automatically ✦ Same trigger system as snippets — one habit, two libraries ☁️ SYNCED, ORGANIZED, ALWAYS READY ✦ Cloud sync — sign in on any computer and your full library is there instantly ✦ Notion sync — edit snippets in a connected database and they update in the browser within minutes ✦ Folder organization — group snippets by team, workflow, or topic ✦ Context menu — right-click any field to insert without typing a trigger WHO IT'S FOR Built for hospitality, sales, and support teams — and anyone who sends repetitive messages or works with AI every day. GET STARTED Install, sign in, then type :: for your snippet picker or """ for your prompt library. Starter snippets and prompts are included. ::: NEW TEAM FEATURE ::: Team sharing lets you share entire folders of snippets and prompts with colleagues. No per-item toggles, no copy-paste. Share a folder once; everyone with access gets the full library, automatically synced across the dashboard, extension, and mobile. The Team hub gives you a single view of your team roster, every folder you've shared (and every one shared with you), who has access to each, and a search across all shared content. Access is folder-level — clean, predictable, easy to manage.
