Own your intelligence · Discover together
Somewhere, in a lab you have never heard of, someone is working on the other half of your breakthrough.
Your Sapience grows from your work and stays with you across AIs. Share what you choose, with your name attached. Sapience is a shared intelligence for humanity, so people and AI can discover what none of us could alone.

Sharing and introductions
A chosen connection starts when you invite a colleague into a shared project. Sapience keeps your AIs in sync.
A found connection is made when your record and a stranger’s contain two complementary contributions to one problem and both of you would benefit from an introduction. Sapience finds complementary work for your problem and introduces the people behind it. Both people accept before anything is shared.
Because knowledge stays owned and credited, Sapience matches it across people and organizations no single vendor could connect. When you choose, what you establish reaches a stranger working on a complementary part of the discovery you are working toward, credited to you, in time to be useful.
Glaciologists needed to sense the whole submerged front of a Greenland glacier. Engineering had the method, distributed fibre-optic sensing, eight years earlier, with no citation path between the fields; by similarity it ranked 22,746th. Sapience re-found the pairing among the first hundred it put forward. The glaciologists made the connection by hand in the end, so this is a connection recovered, not a discovery claimed.
In an internal benchmark on discoveries published after the reasoning model’s training cutoff, Sapience ranked the approach that later won first in 11 of 13 problems, on a small internal set whose protocol we share with partners.

Stays current
Asked what a setting is now in a codebase that keeps changing, Sapience answers 88 percent right on the shipped engine, against 48 for Mem0 and 27 for the same model with git grep, on the same 60 questions.
Scope The same 60 questions on the real git histories of Django, LiteLLM, huggingface_hub and vllm, answers graded against git, no AI judge.

Works across models
The same model scores 86 with Sapience against 20 without it. On OpenAI's own long-context test, Sapience ties GPT-6 Astra, 98.4 against 96.3, reading about fifty times fewer tokens per answer.
Scope BABILong at 128K, the same model: 86 through Sapience against 20 by the first-sentence rule; judge-scored on both sides, 86 against 65. OpenAI MRCR v2, 8-needle items of 512K to 1M tokens, against vendor-published values.

BABILong at 128K, the same model: 86 through Sapience against 20 by the first-sentence rule; judge-scored on both sides, 86 against 65. In this benchmark nothing is fine-tuned and no weights change.
Learns without forgetting
In a two-task study across seven models from 7B to 397B, Sapience forgets 4 to 18 percent of the first task instead of 50 to 94.
Scope Synthetic two-task study on seven open models from 7B to a 397B mixture of experts, 17B active; three seeds per rung.

Synthetic two-task study on open models from 7B to a 397B mixture of experts; three seeds per rung; the 397B has 17B active. With Sapience the second task is learned as well or better. A model trained from its own record also answers tasks it never saw better, +6.01 points. The result is not a guarantee of perfect recall.
The method
Sapience uses an approach based on how people learn. It is built with two speeds, the way a brain is. One part captures what you establish while you work, with its source. The slower part consolidates and continues to improve while you are away: what matters is kept, and what changed is marked as changed, so newer versions take precedence over earlier ones. When you ask, your AI reads a few hundred tokens of what is current instead of your whole history, so answers stay right and cheap as the record grows.
The model underneath is a part you can swap, and each person’s model keeps training on their own work every day. The theory is complementary learning systems, and the results are under Research.
The app
A pre-trained model is trained on information up to a cutoff and then stops learning. The memory other assistants offer is a short list of preferences and details kept inside one product, with no sources and no sharing, so you still explain your project and its constraints again. Sapience keeps learning from all your work, including what you do in other AIs.
The live app, not a mockup, recorded at phone size. The lab is invented, and the waits for the model are shortened.
More of what it does, and who it is for
A living map. Your work organizes itself into a navigable map, from a single thought to the whole of what you know.
Quietly, in the background. It works behind your Claude, GPT, Cursor, or Codex sessions over MCP, reading what you know and writing back what you learn. Reading the few objects that matter instead of your whole history, answers arrive at roughly 1,800x fewer tokens per query once your accumulated work passes a million tokens (a read scales with the question rather than your whole history; on our benchmark corpus). Your plan does more before it runs out, because your AI reads three facts instead of replaying your history.
Your sessions talk to each other. A session can leave an addressed note for another thread, or a future you. Pinned commitments surface when the next session starts, and results return to the thread that asked, across Claude Code, claude.ai, Cursor, GPT, and Codex.
One AI can hold the whole problem. Agent swarms split a problem because one context cannot hold it, and the handoffs between agents lose constraints and drift goals. Sapience keeps what you have established outside the window and brings back only what an answer needs, so the problem never has to be split. Agents become optional workers you add when you want them. Goals hold: the whole problem stays in one mind across long work. Objectives do not quietly drift out from under you.
Three kinds of work it is built for. Research: keep a project’s findings with their sources, and the reasoning behind each decision, across the AIs you work in. Knowledge work: a product lead, consultant or writer keeps a project’s decisions straight across Claude, ChatGPT and the rest. Working together: two people, each on their own AI, plan a trip or a side project, and one AI can use the notes the other person chose to share, with their name on them.
The first time a colleague’s knowledge lights up against yours, the network’s purpose becomes clear.
“It’s amazing to have one brain’s memory infuse all my sessions: my Claude Code and web sessions are fully aware of each other now, and they talk to my Codex sessions too, across providers. That brain is constantly compounding, and it augments my own: it proactively suggests new ideas and connections.”
“This is something incredibly useful. The cross-domain connections are things I would never have found on my own.”
“This is very promising. Having the exact paper referenced is crucial. You know it’s the right thing, not something outdated.”
“Having a 2nd brain that is systematic and can help me keep hold of all the loose strings associated with my work is definitely invaluable.”
“The more collaboration across the world, the faster science progresses. I one billion percent see the benefit.”
A handful of researchers run Sapience in their daily work.
Sapience Labs
Knowledge back with the people who produce it, and moving between them again.
Collaborative superintelligence, as we use the term, is people and their AIs learning from each other, with each contribution credited to the person who made it.
Every AI today learns once and serves one person at a time. Sapience learns continuously from your work and with the people you choose. It provides continual learning at the system level: it never stops learning from your work, and nothing leaves your control. Its unit is the Knowledge Object, one claim reasoned through once, carrying its type, its source, and its edges to the claims around it.
Open standard, sealed engine. The Knowledge Object is an open standard: signed, credited, typed and readable alongside the open formats that already exist. We keep the intelligence that finds the connections for ourselves. CoreTx stewards the standard in the open.
Sapience uses a complementary-learning architecture, with seven patent families filed across it. We are validating performance against the strongest pre-trained baselines and report those numbers separately. All results, with figures, are under Research.
Sapience Labs is a team of scientists and engineers from Google DeepMind, Meta, SpaceX, Harvard, Cambridge, Berkeley and UChicago who have together raised $100M+ for previous ventures. If you want to work on this problem, join the team.
Sapience works with existing laboratories. We start with individual researchers. The intended path runs from individuals to organizations, and then to discovery partnerships. For backing or partnerships, write to Oliver Zahn at oliver@coretx.ai.
Attention appeared in 2014, in an academic lab. The protein-folding breakthrough built on it came six years later, somewhere else entirely. The intelligence existed. The connection was the bottleneck.
Why connection, and why people
An enclosure of knowledge is underway: the big labs bake expert work into private weights and rent it back. What matters next lives in experts' heads and private work, on the order of a million times larger than the web (Trask and Strahm, Institute for Progress, 2025).
Under current arrangements, each scientist is several times more productive while their fields are measurably less connected (Nature, 2026). Much of AI-for-science aims to automate discovery and remove people from the process. Sapience’s discovery process depends on people. Each person decides what to share and recognizes a complementary contribution. What each person learns makes the next person faster.
