Knowly
Knowly is a proactive second brain for Chrome and the web. Save any page, PDF, video or tweet in one click, get a digest written at your level, and let guided learning Flows build themselves from your own sources.
What is Knowly?
Knowly is a proactive second brain built by AInteract PTE. LTD. Its argument is that most AI executes the work your brain has already decided on, whereas a chat assistant can only answer what you already know to ask. Knowly inverts that relationship: it proposes, you choose.
The product is organised as a single guided journey in five stages. First read happens while you browse: a Digest for me button flips any page into a version written for you, with no prompt and no configuration. Connections happens the moment you save: a page, a PDF, a video or a tweet is captured in one click, and Knowly maps it into your library by meaning, so topics build themselves and reshape as you save rather than being filed into folders. Deep dive turns a cluster of sources into a Flow, a guided multi-page journey written at your depth, made of GenPages generated from your own material. Exploration adds GenLink: click any highlighted word and a new page spawns on that concept on the fly. Insight runs while you are logged off, producing Thoughts when Knowly finds a connection or a tension worth your time.
Underneath sits a personalisation model that watches what you save, read, linger on and explore, building a sense of your interests, taste and level so that proactive suggestions do not become noise. The terms describe the service more soberly, as an experimental tool that learns from your browsing activity with your permission and browses the internet on your behalf to produce personalised digests, with outputs that are automated and not guaranteed accurate.
Knowly runs as a Chrome extension paired with a web app. It is in early access: the extension is at version 0.0.20, was updated on 7 July 2026 and reports 461 users. Use is restricted by the terms to personal, non-commercial purposes, and there is no API, no mobile app and no named third-party integration.

When to use Knowly / When not to
A quick filter to help you decide if Knowly is the right fit.
When to use Knowly

Data, GDPR & hosting
A consolidated view of how Knowly handles your data.
GDPR overview
Knowly claims compliance with the principles of the GDPR and the CCPA, and the terms state the privacy policy was designed to comply with the GDPR. Concretely, the policy dated 23 April 2026 lists access, rectification, erasure, restriction and objection, withdrawal of consent and non-discrimination, and extends these rights to every user rather than to EU residents alone. It commits to honouring do-not-track and global privacy control signals where the law requires it, and names Singapore's PDPC alongside EU and US authorities among breach-notification recipients. What is absent matters as much: no Article 27 EU representative, no named DPO, no published DPA, no subprocessor list, no article-by-article legal basis and no mention of standard contractual clauses. The single privacy contact is an email address.
Who owns the data?
AInteract PTE. LTD. claims no ownership over what you put into Knowly. The terms state that you retain all rights in your personal data, browsing information and content, and that the company makes no ownership claim over the digests generated for you, owning only the underlying technology. You grant it a non-exclusive, worldwide, royalty-free licence to use, process, reproduce and modify your data solely to provide and improve the service; deleting content or your account revokes it, though backups may persist briefly. Feedback is the exception, used freely and without compensation. The privacy policy adds that data is never sold and never used to train AI models.
Reuse rights
You may reuse your own material freely. It remains yours, and the digests, generated pages and summaries Knowly produces are described as being for your personal use, with no ownership claimed over them. The limit is commercial rather than technical: the licence to use the service is personal and non-commercial, and reselling or redistributing any part of it, including digests produced for someone else's commercial benefit, requires written permission. Third-party material summarised through Knowly stays the property of its owners, and the terms hand you the responsibility of respecting the conditions of the source sites, including those that forbid scraping or summarising.
Data retention & training
Hosting summary
No hosting country or region is disclosed anywhere on the site: not in the privacy policy, not in the terms, and there is no trust or security page. The policy states only that information will be treated securely and in accordance with the policy regardless of where it is processed, which permits transfers without naming a destination. The publisher, AInteract PTE. LTD., carries a Singaporean private-limited form, and the breach-notification clause names Singapore's PDPC alongside EU and US authorities, which indicates jurisdiction rather than storage location. The domain resolves to an anycast node in the United States, describing the delivery front and not where data is kept. On security, the policy commits to TLS in transit, encryption at rest for sensitive data, role-based access controls, firewalls, intrusion detection and periodic audits. No DPA, no subprocessor list and no standard contractual clauses are published.
Things to keep in mind
Risks and trade-offs to weigh before adopting Knowly.
- Delegating understanding: a tool that digests on your behalf can quietly erode deep reading and recall, and the site itself concedes that understanding cannot be delegated
- Permanent proactivity, with Thoughts arriving while you are away, can turn a learning tool into one more stream competing for your attention
- Deep personalisation of interests, taste and level risks building a comfort bubble that surfaces what pleases you rather than what challenges you
- The extension learns from your browsing activity with your permission: measure the breadth of that access before granting it
- Outputs are automated and the terms do not guarantee their accuracy, so you remain responsible for verifying anything you act on
- The terms push onto you the duty of respecting source sites' conditions, including those that forbid scraping or summarising
- Depending on an early-access service whose free tier can be modified or discontinued at any time, from a vendor with no published address or governing jurisdiction
Setup & Integrations
Technical difficulty
Very low. Setting Knowly up means creating an account and installing a Chrome extension, a one-click install of about 5 MB. Nothing needs configuring afterwards: no prompt to write, no folders to build and no tags to maintain, since the product explicitly promises no prompt and no setup. The only decision deserving thought is granting the extension access to your browsing data, which the terms present as a condition of the service working as intended. There is no API, webhook or developer configuration to handle.

Should you pick Knowly?
Knowly makes an unusually clear promise for an early-access product: rather than executing tasks on command, it goes first. Save what you find, and it digests, connects and returns to you with Thoughts you did not ask for. The vocabulary is coherent from end to end, the five-stage journey is easy to follow, and the pricing page is among the more legible of its category, with four tiers, a genuinely permanent free plan and a Founding Member bonus that doubles credits for now.
Its data posture is a real strength. The vendor states it does not train AI models on customer data, does not sell personal information, leaves you the ownership of both your material and the digests generated for you, and extends GDPR and CCPA rights to every user rather than to EU residents alone.
The counterweight is maturity. This is a young product from a barely documented publisher: extension version 0.0.20, 461 users, one review. There is no postal address, no about page, no contact page and a single email; the terms still carry unfilled placeholders where the governing jurisdiction and the billing currency should be; no hosting country, DPA or subprocessor list is published. The tool is also deliberately narrow, restricted by its own terms to personal, non-commercial use, with no API, no integrations and Chrome as the only browser.
For a curious individual reader who wants a library that organises itself and a system that suggests the next step, Knowly is worth the free plan and costs little to test at 9.99 USD. For anyone needing contractual guarantees, portability or team use, it is too early. The quality of the digests and Flows, which is the whole bet, cannot be judged from the public pages alone.
