TraceMind vs Heyday
Cloud-based AI memory assistant with Notion/Slack/Google Docs integrations; no longer available (listings mark it inactive since late 2024).
Verdict: choose TraceMind if you want private, local recall that cannot be shut down; choose Heyday if you need deep Notion, Slack, and Docs cloud integrations, which is no longer possible since Heyday is inactive.
Best for
- →Private, offline recall that survives any vendor shutdown: TraceMind
- →Cloud integrations with Notion, Slack, and Docs: Heyday, while it existed
- →Screenshots and no-account setup: TraceMind
TL;DR
Heyday is no longer available: directory listings mark it inactive since late 2024, illustrating the availability risk of cloud memory tools. TraceMind keeps its core history index on your device and core search works offline; optional Chat uses the provider you choose.
What is Heyday?
Heyday was a cloud AI memory assistant founded by Sam DeBrule and Samiur Rahman, backed by Spark Capital.
It pulled content into the cloud, added AI summaries, and integrated with tools like Notion, Slack, and Google Docs for $19/month. The service is no longer available; tool directories list it as inactive since late 2024.
What is TraceMind?
TraceMind indexes supported pages it can access and capture. Excluded domains, unsupported browser pages, private browsing, and failed captures are not guaranteed.
Core capture, indexing, storage, search, screenshots, and analytics run locally on your device. Optional Pro Chat sends your question, prior turns in the current chat, and selected matching excerpts, titles, and URLs directly to the AI provider you choose with your own API key. TraceMind does not proxy or store those requests.

Pricing
| Plan | TraceMind | Heyday |
|---|---|---|
| Free | No TraceMind page cap; captured history defaults to keep forever and can be shortened. Browser and device storage capacity still applies. | No longer available (was 14-day trial only) |
| Paid | $5/mo or $50/yr | No longer available (was $19/mo) |
Integrations
Heyday's integrations (Notion, Slack, Google Docs, social feeds) were its strength while it operated. TraceMind intentionally keeps its core history index local and does not depend on a hosted index for core search.
Ease of Use
TraceMind is lightweight and private. Heyday required account setup and cloud permissions; when the service went away, so did access to what it had collected.
Which should you choose?
Choose TraceMind if you…
- ✓Privacy is your top priority
- ✓You want offline access and local control
- ✓You browse in multiple Chromium browsers
- ✓You want a memory tool that cannot be shut down remotely, your index lives on your device
Choose Heyday if you…
- •Heyday can no longer be chosen: the service is inactive. If you need cloud integrations with Notion/Slack/Docs, look at general PKM tools instead
Verdict
Heyday is gone, and hosted memory tools carry an availability risk. TraceMind keeps its core history index in your browser and core search works offline. Sandboxed reading snapshots; resource availability depends on what was captured.
Frequently Asked Questions
What happened to Heyday (heyday.xyz)?
Heyday, the cloud AI memory assistant, is no longer available; tool directories mark it inactive since late 2024. The team had earlier pivoted toward AI meeting notes before the memory-assistant product went quiet.
Can I still migrate from Heyday to TraceMind?
If you exported your Heyday content while it was live, you can revisit supported pages and TraceMind can index captured content locally with AI search and screenshot previews. Going forward, capture still depends on page access and settings.
Does TraceMind integrate with Notion or Slack?
No. Core capture, indexing, storage, search, screenshots, and analytics run locally on your device. Optional Pro Chat sends your question, prior turns in the current chat, and selected matching excerpts, titles, and URLs directly to the AI provider you choose with your own API key. TraceMind does not proxy or store those requests. It focuses on browser history search rather than hosted productivity integrations.
