Bring your workspace together

Your knowledge is scattered across different platforms, documents, and tools. Kepler lets you securely sync your favorite standard workspace apps so your AI always has the full picture. Best of all? Every standard connector is included for free on every tier.

Build your memory on the go

Whether you're on your phone or at your desk, capture links, PDFs, and videos with a single tap. Everything syncs instantly across your devices, keeping your AI grounded in your latest context without breaking your flow.

Works with your AI of choice

Use Kepler through ChatGPT, Claude, Gemini, or any AI tool via MCP. Unlimited and free on every tier. Kepler gives your AI a memory; it doesn't replace it.

Private by design

Kepler cannot see anything behind your logins unless you explicitly connect a workspace app or save a specific page. We don't passively crawl your inbox, hard drive, or private files. Your AI's memory only contains exactly what you choose to give it.

How usage works

AI Assistant credits

AI Assistant credits power built-in AI features and conversations inside the Kepler app. Credits vary by query complexity and feature usage. Hit your monthly limit? Keep querying your Kepler memory through ChatGPT, Claude, Gemini, or any MCP-compatible AI tool at no extra cost.

AI Summaries

An AI Summary performs a deep, computationally heavy process to build your memory. It takes your saved source, extracts the heavy data—like a full video transcript, document text, or image OCR—and distills it into a concentrated memory point for your AI. (Note: Saved Links that just grab surface details like titles and visible text are always unlimited).

Your AI Summary and AI Assistant allowances reset on the first of every month.

Frequently asked questions

  • Why credits instead of "unlimited queries"?

    Because unlimited has a hidden cost. Companies that promise unlimited queries either subsidize heavy users from light users (and eventually pull back), rate-limit you invisibly, or build their AI on cheaper models that produce worse answers. Credits let us give you predictable, transparent capacity using the same high-end AI you'd choose yourself — and pair it with unlimited free access through your existing AI tools.

  • What is a Summary, and why is it limited?

    A Link Capture (which is unlimited on all tiers) grabs the surface details of a webpage. If you save a YouTube link, Kepler grabs a quick, shallow summary of the video's title and description so you can find it later — but it doesn't process the video itself. That's where a Summary comes in. A Summary performs a deep extraction — like pulling the full YouTube transcript, reading a 50-page PDF, or scanning an image. Kepler processes this heavy data into a highly optimized memory artifact for your AI.

  • What happens if I hit my limits?

    AI Assistant credits exhausted: Kepler's built-in AI assistance pauses for the month, but you can keep using your memory with ChatGPT, Claude, or any MCP-compatible AI tool at no extra cost. Summaries exhausted: You can still save YouTube videos or PDFs, but they will be processed as Saved Links (surface details only). You can run a deep Summary on them later once your allowance refreshes.

  • Can I use Kepler with my existing ChatGPT or Claude subscription?

    Yes — that's the point. Kepler is designed to make the AI you already use smarter by giving it your context. Connect Kepler to ChatGPT or Claude via MCP. We never charge for that. You bring your AI; we bring the memory.

  • What's the difference between memory search on Free and Pro?

    Every tier uses your memory to ground answers. Pro's Advanced Memory Search reaches further into your library on each query and builds a richer context set, so the AI has more of the right material to work with — whether you're in Kepler or using an external AI through your connection. It improves the quality of what comes back; it never limits how often you can ask.

  • Do you offer a Team plan?

    Yes. Enterprise is for teams and organizations that need shared memory, premium connectors, security controls, custom review, and dedicated support.

  • What happens to my memory if I downgrade?

    Nothing. Your saved links, annotations, and memory graph belong to you and stay with your account regardless of tier.

Capture anywhere.

Save what matters from browser or mobile, then manage your memory and spaces in Kepler.
