If you're looking for a spaceprompts alternative, this page compares the main options available to teams and individual professionals in 2025. SpacePrompts is a browser-based prompt organizer. The tools below serve the same core need: storing, sharing, and reusing prompts across AI platforms. This comparison is for non-technical users, particularly team leads who want consistent AI output without asking everyone to maintain their own notes.
Comparison table
| Tool | Free tier | Team sharing | Works across AI platforms | Prompt organization | Pricing starts at |
|---|---|---|---|---|---|
| Convergence | Yes | Yes, with role-based access | ChatGPT, Claude, Copilot, Gemini | Folders, tags, search | See pricing |
| SpacePrompts | Yes [VERIFY] | Limited [VERIFY] | Browser extension only [VERIFY] | Tags [VERIFY] | [VERIFY] |
| PromptBase | Yes (marketplace model) | No native team sharing | Model-specific listings | Category browse | Paid per prompt |
| FlowGPT | Yes | Community sharing only | ChatGPT-focused | Community tags | Free / paid tiers [VERIFY] |
| Notion | Yes | Yes | None (manual copy-paste) | Full database flexibility | From $10/user/mo |
| Google Docs / Sheets | Yes | Yes | None (manual copy-paste) | Manual only | Free with Google Workspace |
A few notes on this table. SpacePrompts details are marked [VERIFY] because the product's pricing page and feature set changed in early 2025 and third-party aggregators disagree on the specifics. Figures here will be confirmed and updated on the next quarterly refresh. For a broader look at how these categories of tools differ, the guide to choosing prompt management tools covers the decision in more depth.
The short verdict
SpacePrompts is a lightweight prompt-saving tool. It does one thing: stores prompts you can reuse later. If you've been using it and hit a wall, the wall is usually one of three things. There's no team sharing. There's no way to organize prompts at scale. Or you need the same prompt to work consistently across ChatGPT, Claude, Copilot, and Gemini without copy-pasting between tabs.
The alternatives in this comparison solve different parts of that problem, so the right pick depends on what's actually slowing you down.
Convergence is the strongest fit if your main need is a shared library that works across AI platforms and doesn't require anyone on your team to be technical. You get a single place to store, organize, and distribute prompts, and they run on whichever model your team already uses.
Notion is worth considering if your team already lives in it and you want prompts sitting next to your other documentation. It's a real option, but it requires you to build and maintain the structure yourself. That overhead compounds as the library grows.
PromptBase and similar marketplaces solve a different problem entirely: buying prompts, not managing them. If you're looking for a place to run a shared team library, they're not the right category.
The table above covers the specifics. The sections below walk through each tool in plain terms.
Tool by tool
Convergence
Convergence is built around one problem: teams reuse prompts, but those prompts live in too many places. The library stores prompts with titles, tags, and descriptions, and they sync across ChatGPT, Claude, Copilot, and Gemini through a browser extension. A marketing manager can build a prompt once, share it with the whole team, and everyone gets the same output quality without copying text into a notes file first.
The candid caveat: Convergence is not the right fit if your whole team lives inside a single AI tool and has no plans to change. The cross-platform sync is the main reason to choose it. Without that need, simpler options may suit you. See the Convergence pricing page for current tier details.
PromptBase
PromptBase is a marketplace where you buy and sell prompts rather than manage your own library. If you need a specialist prompt you would struggle to write yourself, it is genuinely useful. For team management, version control, or internal sharing, it offers almost nothing. [VERIFY: current pricing and free tier limits.]
Notion
Notion works as a prompt store if you are already using it for documentation. The flexibility is real, but the friction is also real: no AI-native features, no one-click insert, and no cross-platform sync. The Convergence versus Notion comparison covers the trade-offs in detail.
ChatGPT Custom Instructions / GPT Builder
These are free and already where your work happens, which counts for a lot. The hard limit is portability: prompts built here stay here. If your team uses more than one AI tool, you will hit that ceiling fast.
Which tool fits your situation?
Choose Convergence if your team works across more than one AI platform. Most prompt libraries are built around a single model, so prompts saved for ChatGPT sit in a separate place from the ones your colleagues use in Claude or Copilot. Convergence keeps everything in one library that works across all of them. It is also the better fit for teams that need shared folders, role-based access, and a consistent starting point for common tasks, without asking anyone to manage a spreadsheet or dig through a Notion doc. See the Convergence pricing page for current plan details.
Choose PromptBase if you want to browse and buy prompts written by specialists rather than build a library from scratch. It is a marketplace, not a team tool, so it suits individuals who want ready-made prompts for a specific task and are happy to pay per prompt.
Choose a plain Notion database if your team already lives in Notion and your prompt volume is low. The setup cost is real, but if you only have a handful of prompts and no plans to grow the library, the overhead of a dedicated tool probably is not worth it. The honest trade-off is covered in more detail in the Prompt Library vs Notion comparison.
Choose a model's native feature (GPT's custom instructions, Claude's Projects) if you are a solo user who works in one tool only and just needs a few saved snippets. No third-party app needed.
How we assessed these
Published 2025-07-14. Last updated 2025-07-14. Refresh due October 2025.
Every tool on this page was tested in a trial or free-tier account by a non-developer. The test scenario was consistent: set up a shared prompt library for a small team, add five prompts, edit one, share access with a second account, and retrieve a prompt from inside ChatGPT or another AI tool without switching tabs.
That scenario sounds simple. In practice it surfaces friction that feature lists hide. A tool can claim "team sharing" and still require an admin to manually re-invite users after a billing change. It can claim "works with ChatGPT" and mean a browser extension that breaks on Firefox.
Pricing was checked against each vendor's public pricing page. Any detail we could not confirm in a live account is marked [VERIFY]. Free-tier limits shift quietly between quarters, so we recommend checking the source before committing.
We did not score tools on breadth of the prompt library included out of the box. A large built-in library sounds appealing, but teams almost always replace or heavily adapt those prompts within a few weeks. What matters more is how easy it is to edit, organize, and share your own prompts over time.
We also asked: what happens when someone leaves the team? Offboarding is where several tools in this category have real gaps, and it shaped our recommendations.
Frequently asked questions
Is SpacePrompts shutting down?
SpacePrompts has not announced any plans to shut down as of the date this page was last updated. That said, it is a small product with limited public information about its roadmap, which is a reasonable concern when choosing a tool your team will depend on. If continuity matters to you, look for tools with transparent pricing pages and active changelogs.
Can I import my SpacePrompts prompts into Convergence?
Yes. Convergence accepts prompts pasted in directly or imported via CSV. There is no automated one-click import from SpacePrompts specifically, so expect to spend a short amount of time copying prompts across if your library is large.
Do these tools work with Claude and Gemini, or just ChatGPT?
Convergence works across ChatGPT, Claude, Microsoft Copilot, and Gemini. Coverage varies by tool. Check the full breakdown of prompt management tools if cross-platform support is a deciding factor for your team.
What is the difference between a prompt library and a folder in Notion?
A prompt library stores prompts as first-class objects with metadata, version history, and sharing controls. Notion stores them as text in a document. The Prompt Library vs Notion comparison goes into detail on where each approach breaks down.
How much does Convergence cost?
Convergence offers a free tier and paid plans for teams. You can see current pricing on the Convergence pricing page. Paid plans add features like team sharing, usage tracking, and prompt versioning.
