What changed in each version of PromptMason, newest first. To install or update, see the Read me.

Version 1.3.1

October 31, 2026

Prompt sets, and Settings that are easier to find your way around

Better answers from the guides

  • Asking how to do something now finds the right part of the guides more often, even when you don’t use the guides’ own words. For example, asking how to restore something you archived finds Bring back an archived item, and asking how many prompts the Free plan allows finds the Plans and limits guide.
  • This works the same in the search box on Help, when you ask Chat about PromptMason, and when your AI agent looks something up in the guides.
  • Your AI agent now links to the part of the guide its answer comes from. See Look things up in the guides.

Your AI agent can get a Skill as a zip file

  • Your AI agent can now get a Skill as a zip file, the same file Download Skill saves. It gets the file, its name and a checksum, so it can check that nothing changed on the way. If you haven’t changed the Skill, it gets the very same file every time.
  • This works in Read-only mode too, because it only reads. See Get a Skill as a zip file.

Import a Skill from a zip file

  • Click Prompts, then New, then Import a Skill… to bring in a Skill you already have as a .zip file. It works with a Skill you downloaded from PromptMason, and with one you exported from Claude or another AI app.
  • The Skill is added to your list with its fields and its files. If PromptMason had to change something, or a file couldn’t come in (a picture, for example), a window tells you. See Import a Skill.

Send diagnostics to support

  • When something isn’t working, click Help, then Get help from support. Save diagnostics file saves a file that tells support which version you have, how PromptMason is set up and the recent errors it noted. Email support asks which email you use (Gmail, Outlook.com, Yahoo Mail or the email app on this computer), opens a message to support there, and shows the file in its folder so you can drag it in.
  • The file records what PromptMason did, such as starting, syncing, checking for updates and AI requests, with counts and times, so support can follow what happened.
  • The file never holds the names or text of your prompts, blocks, variables or chats, or your keys and passwords. Click See what’s included to read every word of it first.
  • The same buttons are in Settings → General, and on the card PromptMason shows if your library can’t load. See Send diagnostics to support.

Labels for the values in a list

  • A variable that offers a list of values can now give each value a label, such as Prod for https://app.example.com. Type it in the Label box beside the value on the Variables screen.
  • When you fill in your values, in the app and in the Chrome extension, the list shows each label with its value, and typing finds either one. Only the value is copied.
  • Your AI agent sees the labels too, so it can offer you the values by name. It fills in the value, never the label. See Offer a list of choices.

Prompt sets

  • A prompt set puts your prompts in order, one step after another. Click Prompts, then New, then Prompt set, drag prompts from the list on the left onto the canvas, put them in order and click Save prompt set.
  • Copy to Clipboard copies every step’s text, one after another. A value asked each time is asked once and fills every step that uses it. The Chrome extension shows and copies a set the same way.
  • Your AI agent can run a set: it reads the steps with get_prompt_set, then runs each prompt in turn and carries each answer into the next. It can also make and change sets. A set counts as one prompt. See Prompt sets.
  • Each step has Include Step Number and Include Name boxes, like a block’s Include Name and Include Type. Tick one to put it in that step’s heading. How new steps start is set in Settings, then Blocks & prompts, the same way as for blocks. See Choose each step’s heading.
  • A prompt that a set uses shows Used by with the sets, so you can see where it runs. A long list of steps scrolls instead of filling the pane.

Settings that are easier to find your way around

  • AI & connected apps now has three tabs: AI providers, AI instructions and Connected apps. Chat has Chats and Web tabs.
  • Each AI provider is one short row. Click Set up or Edit to open it. Your own AI server is now with the other providers.
  • A small (i) next to a name, such as Connected apps or Recovery kit, says what it’s for. Point to it or click it.
  • Search shows which tab a setting is on, and picking a result opens it there. See Settings.

A formatting bar for documents

  • The Markdown document editor has a formatting bar: Bold, Italic, Heading, lists, Quote, Code and Link. Ctrl+B, Ctrl+I and Ctrl+K work too, and Ctrl+Z takes back what a button did. A Skill’s instructions have the same bar. See Format with the toolbar.

Kind and Category

  • What an item is, such as a Static Prompt, a Dynamic Skill, a Prompt set or a Document, is its Kind. A prompt’s Type is now its Category: a label you choose, such as User Prompt, System Prompt or one of your own, or No category. Changing the Category never changes what the item is. Blocks keep their Type.
  • On the Build screen, Build a: Prompt | Skill | Prompt set picks what you’re making. To turn a prompt into a Skill, right-click it and click Make it a Skill. Make it a prompt turns it back, and its text is kept.
  • Markdown documents now show as Document in lists, filters and on Home, and a chat can follow any document. Your own categories are in Settings, then Blocks & prompts, under Prompt categories. See Block types and prompt categories.

Quick Launch your way

  • Click the gear on Quick Launch on Home to open Customize. Choose how many columns and rows it uses, tick the tiles you want and put them in order.
  • There are five new tiles: New Document, New Prompt Set, New Folder, New Variable and New Skill. Your Home looks the same until you change it. See Customize Quick Launch.

Smaller improvements

  • AI assist for documents. AI assist now treats a Markdown document as plain writing. It no longer adds a name, a description or other Skill fields at the top. If you changed the instructions for Markdown documents in Settings, yours are kept, and Use the new default beside them switches to the new ones.

What you need to do

  • Before you update: nothing. Your blocks, prompts, settings and license are kept.
  • After you update: if you use an AI agent with PromptMason, this update gives it new tools, for getting a Skill as a zip file and for reading, making and changing prompt sets, and lets it add or change the labels on a list’s values. It sees the labels straight away. To get the new tools and set labels in Claude Desktop, install the PromptMason extension again; restarting Claude is not enough. Restart Cursor or Claude Code. If an AI agent is still using the old tools, the bell in PromptMason tells you and takes you to the fix. See Connect an AI agent.

Good to know

  • A library shared between computers: a computer that hasn’t updated yet shows the list’s values without their labels. If someone changes the list there, each value they keep keeps its label. Nothing else is lost.
  • Categories on a computer that hasn’t updated: it shows the Category as the Type, as before. If someone changes the Type there, that becomes the Category on your other computers.
  • Prompt sets on a computer that hasn’t updated: it shows a set as an empty prompt until it updates. Nothing is lost: the set and its steps are kept on your other computers, and come back when that computer updates.

Introducing Skills

Skills for your AI apps

A Skill is a set of instructions that an AI app follows when a job matches it. Skills are an open format: Claude, ChatGPT, Cursor, GitHub Copilot, Gemini CLI and many other AI apps support them. Now you can make them in PromptMason.

  • Build one, or write one. Make a Dynamic Skill from your blocks on Build, or write a Static Skill on Prompts, then New, then Skill. A Front matter card holds the name and description an AI app reads first, and tells you what to fix as you type. A Skill can carry extra files, such as a reference page.
  • Download it. One click gives you a .zip folder in the standard Skill format, checked first. Copy SKILL.md puts the finished file on your clipboard instead.
  • Save one from a connected AI app. Ask an AI app that is connected to PromptMason to save a Skill, and it lands in your library, ready to edit or download. Every Skill you have is also in the Skill picker in Chat.

See Skills for the steps.

A better place to write

  • The Markdown editor has a screen of its own. Open it from Prompts, then New, then Document.
  • What you type is saved exactly as you typed it, so links, code and tags reach your AI apps unchanged. Prompts and blocks always show their formatting, with bold as bold and lists as lists, and text color is gone from the editor. Copying as plain text keeps links, code, quotes and tables as you wrote them. See Formatting, block headers and hidden notes.

Your AI agent can read the guides

Your AI agent, such as Claude Desktop or Cursor, can now look things up in PromptMason’s guides, the same way PromptMason’s Chat does. Ask it “How do I turn on backups?” and it answers from the guides, with a link to the guide. See Look things up in the guides.

The bell keeps you up to date

  • After an update, the bell reminds you to read What’s new, until you open it.
  • When an AI app you’ve connected, such as Claude Desktop, is using an older copy of PromptMason’s tools, the bell tells you and takes you to the fix.
  • When there’s a new local model to try, the bell tells you.

See Notifications.

Smaller improvements

  • Not everyone has to update at once. In a library you share between computers, Manage shows Older PromptMason next to a PC that hasn’t updated yet, and the bell tells you while one is behind, or when yours is. Nothing is lost while it catches up. See A PC is on an older PromptMason.
  • Stop syncing on one PC. If your personal library syncs between your PCs, you can now stop syncing on any of them except your approving PC. That PC keeps its copy, and your other PCs and your recovery kit keep working. See Take one PC off your personal library.
  • Home without packs. Turn on Leave pack items out of Home in Settings, then Features, and Home’s counts, rankings and charts include only what you made. See Leave pack items out of Home.
  • Long descriptions. A long description now scrolls in its own box, so the prompt or document below it stays in view.
  • A clearer switch name. The Markdown editor switch in Settings, then Features, is now called Markdown documents. It shows or hides making and editing documents. Skills are separate and always available.
  • Installing on Windows. The installer’s last page now asks whether to add a desktop shortcut and whether to start PromptMason. Updates leave your desktop as you set it.

What you need to do

  • Before you update: nothing. Your blocks, prompts, settings and license are kept.
  • After you update: if you use an AI agent with PromptMason, this update gives it new tools for Skills and for looking things up in the guides. In Claude Desktop, install the PromptMason extension again to get them; restarting Claude is not enough. Restart Cursor or Claude Code. If an AI agent is still using the old tools, the bell in PromptMason tells you and takes you to the fix. See Connect an AI agent.

Good to know

  • A library shared between computers: a computer that hasn’t updated yet shows a Skill as a plain prompt, without its extra files, until PromptMason updates there. Nothing is lost.

Version 1.2.1

Easier license keys

Pro, unlocked

  • Any license key you got from us now unlocks Pro until its own end date, so activating one is simpler.

Version 1.2.0

October 21, 2026

Choose your private AI model

More choice for the AI on your computer

  • The free AI model now comes in three sizes. The first is small, runs on the processor and needs no graphics card. Two larger models give deeper answers on a computer with a graphics card of its own.
  • Each model shows what it needs, so you can see before you download whether it suits your computer.
  • You can choose how long a model stays in memory when you are not using it.

Your default stays yours

  • Downloading or removing a model, or adding or removing an AI key, never changes your default AI provider. If your default can’t be used on a computer, AI assist uses the local model or the first provider you have set up, so it keeps working.

Version 1.1.0

October 18, 2026

A bigger prompt library

New in the prompt library

  • The prompt library on promptmason.ai has Mega packs, one for a profession or an industry, each with a few hundred blocks and the prompts built from them. Every pack has its own page showing what is inside, and you add it from a file in Settings, then Backup & data.
  • Three new starter packs come with PromptMason: Sales, HR and Customer support.
  • On the Free plan you can still add a Mega pack and read all of it before you decide about Pro. PromptMason tells you what will happen first.

Chat and Home

  • Save a whole chat as a file, and select and copy any part of a message. Chat replies from your own AI provider can also run longer.
  • Search the charts on Home to see one block or prompt and everything joined to it. New Chat is now one of the quick buttons.

Help when you need it

  • Every page on promptmason.ai has a help chat that answers questions about PromptMason.

Version 1.0.1

October 15, 2026

Your library follows you

Your other computers feel like home

  • Your favorites, star ratings and the version history of every item now come along when you sync your personal library. A new computer joins with all of it in place, and you can keep working while a long history comes down.
  • Your settings follow you too, such as your theme, your shortcuts, which features are on and your default AI. Things that keep you safe or belong to one computer stay where they are: your API keys, the local model and App Lock.

If your computers were already syncing, update PromptMason on each of them. Each one then shares its favorites and history once.

Version 1.0.0

Welcome to PromptMason

Write once, use everywhere

  • Build prompts from blocks. Write a piece of a prompt once, such as your tone of voice or a standard format, and use it in as many prompts as you like. Change the block and every prompt made from it follows.
  • Fill in names and details with variables when you copy a prompt, so it is ready to paste into any AI app.

Works with your AI

  • Connect Claude, Cursor or Claude Code to your library, so they can find and use your blocks and prompts.
  • Use a free AI model that runs on your own computer. It needs no account and no key, and your text stays on your computer.

Your library, on every computer

  • Keep your library in step across your computers, or share one with your team, through a cloud folder you already use, such as OneDrive or Dropbox. What is in that folder is encrypted, so the cloud company can’t read it.

PromptMason starts with 14 days of Pro, with no card and no key. After that it moves to the free plan, which has every feature and holds 25 blocks and 15 prompts.
