LLMnesia vs AI Toolbox: AI Chat History Extension Comparison
AI Toolbox is a paid organisation suite for ChatGPT, Gemini, Claude and Grok with folders, prompts and full-text search capped at 5 results per query on the free tier. LLMnesia is a free, local-first Chrome extension that indexes your AI chat history automatically and gives you unmetered full-text search across 10+ platforms with direct jump-back to the original conversation.
AI Toolbox and LLMnesia both attack the same problem: useful answers buried in past AI sessions that native history makes hard to find. AI Toolbox (formerly ChatGPT Toolbox) is an organisation suite covering ChatGPT, Gemini, Claude and Grok, with folders, a prompt library, bulk tools and full-text search. Its free tier caps search at 5 results per query and 3 exports a day, and full access is sold per platform at $9.99 a month, or $199 for the all-platform bundle. LLMnesia is a free, local-first Chrome extension that indexes and searches the full text of your conversations across ChatGPT, Claude, Gemini and 10+ platforms, with direct jump-back to the original. The deciding question is whether you want a paid, folder-driven suite for four platforms, or a free, unmetered retrieval layer that covers more of them.

What AI Toolbox does
AI Toolbox (around 40,000 users, 4.6 stars from 555 ratings on the Chrome Web Store) grew out of ChatGPT Toolbox into a management suite spanning ChatGPT, Gemini, Claude and Grok. It is a mature, monetised product with a wide feature set:
- Folders and subfolders for filing conversations, plus smart tagging. The free tier allows 2 folders.
- Full-text search across indexed messages, with a search that can span all four platforms at once. The free tier returns at most 5 results per query.
- Prompt library with reusable templates, multi-step chaining and @@ context references. The free tier holds 2 prompts.
- Bookmarks, bulk delete and archive, and export, with export capped at 3 a day on the free tier.
- Platform extras such as a Claude artifacts vault, Gemini image watermark stripping, and ChatGPT audio downloads.
- Local conversation storage: its privacy policy says conversations are stored locally in your browser and never permanently stored on its servers; device sync, which is paid, covers organisational metadata like folders and tags and is encrypted at rest.
- Pricing: a free tier with the caps above, then $9.99 a month or $99 lifetime per platform, a $199 one-time All Access bundle for every platform including future ones, and a per-seat teams plan.
That breadth is what you would expect from a mature paid suite. The catch is that it is priced per platform, and its free tier keeps search results, exports and organisation on a short leash.
What LLMnesia does
- Automatic background indexing: sessions are indexed as you work, with no folder filing or connect-and-organise step.
- Unmetered full-text search across supported platforms, with no result caps or monthly limits.
- Direct jump-back links that take you to the exact original conversation, not just a stored copy.
- Local-first: your index stays on your device.
- Coverage across 10+ platforms in one free extension, with no per-platform pricing.
Where they differ most
Three differences matter more than the rest. First, cost and metering. AI Toolbox sells access per platform: $9.99 a month for one, $199 to unlock all four. Even before you pay, the free tier caps search at 5 results per query, exports at 3 a day, and organisation at 2 folders. LLMnesia is free, covers every supported platform at once, and does not meter search at all. Second, the organisation model. AI Toolbox is built around filing conversations into folders and then searching the index, which works well if you enjoy organising but is overhead if you just want the answer. LLMnesia indexes everything automatically in the background and links each result straight back to the live original, so there is nothing to file and nothing to maintain. Third, coverage. AI Toolbox spans four platforms; LLMnesia covers the major platforms and 10+ in total under one free install.
On conversation content, both keep the chats themselves local: AI Toolbox's privacy policy explicitly says conversations are never permanently stored on its servers. The privacy line to watch is the paid layer: device sync routes your folders, tags and other metadata through its servers (encrypted at rest), and its Chrome Web Store listing discloses that it collects personally identifiable and authentication information. LLMnesia has no account, no sync and nothing that leaves your machine.
A concrete example
Say you worked out a tricky data-cleaning approach in ChatGPT three weeks ago, then half-revisited it in Claude. With AI Toolbox's free tier, a search returns at most five hits per query, so if the conversation you need is not in that top handful you rephrase, dig through folders, or upgrade. With LLMnesia you search pandas dedupe approach, get full-text hits from both platforms, and jump straight back into the original ChatGPT session to copy the exact code, no caps involved. Both recover the answer; one gates the depth of search behind per-platform pricing, the other is unmetered and lands you back in the source. This is the everyday retrieval covered in the best Chrome extensions to save and search AI conversations.
Can you use both together?
You can, but they overlap on search, so most people pick one. Choose AI Toolbox if you want folders, prompt chaining, bulk tools and platform extras across four platforms, and per-platform pricing fits how you work. Choose LLMnesia if you want a lean, free, search-first tool that indexes automatically across 10+ platforms, never meters search, and gets out of the way.
Choosing between them
AI Toolbox is a better fit if:
- You want a full organisation suite: folders, prompt library with chaining, tagging, bookmarks and bulk actions.
- You mostly live in ChatGPT, Gemini, Claude and Grok, and per-platform pricing is acceptable.
- You are happy filing conversations into folders as you go.
LLMnesia is a better fit if:
- You want unmetered, search-first retrieval with no result caps or monthly limits, free.
- Automatic background indexing with nothing to organise matters to you.
- You want direct jump-back to the original conversation across 10+ platforms in one install.
Want lean, automatic, unmetered retrieval? Install LLMnesia free.
Frequently asked
Is AI Toolbox free?
AI Toolbox has a free tier capped at 2 folders, 2 bookmarks, 2 saved prompts, 5 search results per query, and 3 exports a day. Removing the caps costs $9.99 a month per platform, $99 lifetime per platform, or $199 for the all-platform bundle. LLMnesia is a free Chrome extension with no caps on search.
Are AI Toolbox and LLMnesia both local-first?
Both keep conversation content in your browser. AI Toolbox's privacy policy says conversations are never permanently stored on its servers, and its paid device sync covers organisational metadata such as folders and tags, encrypted at rest. Its Chrome Web Store listing discloses that it collects personally identifiable and authentication information. LLMnesia has no account and no sync: nothing, including the index, leaves your device.
How many platforms does each one cover?
AI Toolbox covers four platforms: ChatGPT, Gemini, Claude and Grok. LLMnesia covers the major platforms and 10+ in total. Coverage changes with updates, so check each extension's current release notes for the definitive list.
What is the main difference in search?
AI Toolbox indexes your messages for full-text search, but the free tier returns at most 5 results per query, so older or rarer hits can sit out of reach until you pay. LLMnesia's full-text search is unmetered, and every result links straight back to the live original conversation.
Does AI Toolbox do more than LLMnesia?
In breadth, yes. AI Toolbox adds folders and subfolders, a prompt library with chaining, smart tagging, bookmarks, bulk delete and export, and platform extras such as an artifacts vault. LLMnesia deliberately stays narrow: automatic indexing, unmetered full-text search, and jump-back to the original. The choice is a paid organisation suite versus a focused, free retrieval layer.
Can I run both at once?
You can, but they overlap on search, so most people pick one. Run AI Toolbox if you want folders, prompt chaining and bulk tools across four platforms and the per-platform pricing works for you. Run LLMnesia if you want free, unmetered, search-first retrieval across 10+ platforms that indexes automatically and gets out of the way.
