Best for: thredly
thredly compresses a long AI conversation into a structured handover you can paste into a fresh chat, so the instructions, decisions and progress survive when a thread hits a context limit or a model starts forgetting what was agreed twenty messages ago. The vendor is careful about what it is not: this is a handover artefact, not persistent memory for the model, and the site says so explicitly rather than implying continuity it cannot deliver. The Chrome extension operates directly inside ChatGPT, Claude and DeepSeek, summarising in the browser with no install step required for the web app path. The web app produces a copyable handover suitable for any text-based assistant, including Gemini and Perplexity, which makes it a practical way to move a stalled thread from one model to another mid-project. Input is removed after processing. The documented use cases are the concrete ones: continuing a long ChatGPT conversation without losing decisions, compressing a thread that has hit a message limit, and switching models without restating the whole brief. The extension is rated 4.3 on the Chrome Web Store. The free tier is a single one-time summary at signup rather than a recurring allowance, with paid tiers metered by summary count and how long saved threads are retained.
