v0.8.0 · Released
PromptMate · What's new

Variables, Groups
& User Context.

PromptMate now lets reusable prompts behave more like small, structured tools. Fill variables at send time, organize prompts into groups, attach shared group instructions, and append persistent personal context across platforms.

Feature 01 · Variables in Prompts

Turn any prompt into a fill-in workflow.

Add {{variable}} placeholders to any prompt. When you click Use, PromptMate opens a fill-in dialog, collects the missing values, and shows a live preview before inserting the final prompt. No more editing in the chat box after pasting.

Variables are detected automatically. Fill in each field, see the live preview, then send.

Write {{variable}} anywhere

Type any {{placeholder}} in the prompt editor. PromptMate picks it up at send time.

Feature 02 · Prompt Groups

Keep the sidebar tidy with named groups.

Organize prompts into named groups — by project, platform, or use case. Each group shows a count and collapses cleanly so the sidebar stays fast to scan, even when your library grows.

Groups in the sidebar

Named groups with counts and grouped prompt cards. Variable badges show which prompts have fill-in fields.

Feature 03 · Group Instructions

Attach shared instructions once, apply to every prompt.

Set a group instruction and PromptMate appends it to every prompt in that group — after user context, before the prompt body. Shared role setup, tone guidelines, or system context: write it once at the group level, not on every individual prompt.

Group instruction modal

Enable a shared instruction for the whole group. It travels with every prompt in that group.

Feature 04 · User Context

Your background, attached to every prompt.

Save your role, background, and preferences once in the User Context settings. PromptMate appends it at the top of every outgoing prompt — across all supported platforms — without you touching it again.

Use it today

A practical v0.8 setup path.

The new features work together. Start with the broadest layer, then make individual prompts smaller and easier to reuse.

01

Add user context first

Write the stable background you keep repeating: role, stack, audience, and preferences. Keep it broad enough to help most prompts.

02

Create 2-3 starter groups

Start with groups like Code Review, Writing, or Learning. Add group instructions only when every prompt in that group needs the same rule.

03

Convert edits into variables

If you always replace a topic, diff, error, audience, or feature goal after pasting, turn that piece into a {{variable}}.

04

Preview before inserting

Use the live preview to catch vague variable values, missing context, or instructions that should move into the group instead.

How it stacks

The anatomy of an outgoing prompt.

In v0.8.0, PromptMate assembles your final prompt in a defined order — so every layer lands in the right place for the AI to read it correctly.

Final prompt sent to the AI Top → Bottom
User context Your role and background — set once, applied always.
Group instruction Shared instruction from the group — appended automatically.
Prompt body Your saved prompt — the core task.
Variables resolved {{variable}} placeholders replaced with your fill-in values.
Tone and format Response style and output shape — applied so the answer scans the way you expect.

Prompts that work like tools.

Update to v0.8.0, set your user context once, organize your library into groups, and start writing prompts with variables. The same library — smarter now.
