My 1M token Gemini chat died, so I built a tool to bring it back to life.

Harnessing Persistent Memory for AI Conversations: Introducing Nessie

In recent weeks, many users of AI chat platforms have faced a common challenge: the limitation of conversation context. Particularly for those engaging in large-scale, long-term interactions, these constraints can disrupt creative workflows, derail ongoing projects, and result in significant data loss.

The Problem of Context Limits

One notable case involved a developer managing a critical startup project through AI conversations that accumulated over a million tokens—encompassing the entire history of their enterprise. When the conversation hit the platform’s context limit, access to vital information was abruptly cut off, essentially “killing” the ongoing dialogue. Similarly, long-standing personal chats faced the same fate, leaving users to grapple with fragmented and incomplete histories.

Introducing Nessie: A Solution for Enduring AI Memory

To address this challenge, a new tool named Nessie has been developed. Built on Gemini AI models, Nessie enables users to import and sustain extensive conversation histories, effectively providing AI with a form of permanent memory. This approach ensures that the continuity of complex, long-term projects and personal dialogues remains intact, despite platform-imposed constraints.

How Nessie Works

The core functionality of Nessie revolves around importing existing conversations from platforms like Gemini, ChatGPT, and Claude. Once imported, users can continue their interactions seamlessly without the disruption of context resets.

Security and Privacy

A key priority for Nessie is user privacy. Data processing is conducted locally within the user’s browser, ensuring that no information leaves the device unless explicitly chosen to be uploaded. Users maintain full control over their data, with options to select specific conversations for import and to delete data at any time.

Demonstration and Community Engagement

To showcase its capabilities, Nessie offers a straightforward demo available on YouTube: https://www.youtube.com/watch?v=pALstDDfKMg. The developers are actively seeking honest feedback from builders and power users—those most impacted by conversation limitations—to help shape the tool’s future development.
