Gemini for Developers: Find Every Past Coding Session

Developers use Google Gemini for debugging, code generation, log analysis and architecture questions, often pasting whole files into its 1 million token window. The working fix then sits in a sidebar list that only searches titles. The Gemini module of AI Toolbox (formerly ChatGPT Toolbox), a Chromium extension by Infi Developments, adds full-text search across every message with exact-match, role and date filters, folders per project, message bookmarks, @@ Context Mentions and export to Markdown, JSON, PDF or TXT, all inside gemini.google.com.

Free with 5 search results per query, 2 root folders, bookmarks in 2 conversations and TXT export. Premium removes the caps and adds the Advanced filters, Markdown, JSON and PDF export and bulk actions.

AI Toolbox Advanced Search on Gemini with Exact match on, Questions and Answers role pills, Past week, month and year date filters, and 67 highlighted matches across 32 conversations

Advanced Search on gemini.google.com

  • Exact match for a stack trace, an error string or a version number
  • Questions or Answers to keep only your prompts or only Gemini's replies
  • Past week, month, year or a custom range; free search covers every message with five results per query

The gap

What Gemini gives developers, and what it loses

Gemini has a title-only sidebar search, a share menu that sends one reply to Docs or Gmail, and Google Takeout for the whole account. None of them find the regex you fixed in March by searching for the error message.

A coding session is worth keeping when it ends in a working fix. In Gemini that fix sits inside a reply in a chat titled by its first line, one of hundreds. The sidebar search matches titles; Gems are custom assistants, not folders; and Takeout returns your account's activity as HTML rather than a readable file per conversation.

AI Toolbox keeps the Gemini interface and adds the missing layer in the browser: an index of every message you can query by function name or traceback, folders with subfolders, bookmarks on the replies that solved something, an @@ picker that pulls an earlier thread into a new one, and per-conversation export in developer-friendly formats. Nothing is uploaded; the index lives in your browser.

Why it matters

Here is what you cannot do with Gemini alone:

  • Search by error message. Native search matches chat titles, not the traceback inside a reply.
  • Group chats by repo or service. The sidebar is one recency-ordered list and a Gem is an assistant, not a folder.
  • Export one conversation as Markdown or JSON. The share menu sends a single reply to Docs; Takeout dumps the whole account.
  • Reuse an earlier thread as context. You paste it back in by hand; there is no way to reference a past conversation.

The longer you use Gemini for code, the more of your solved problems sit in old replies. Search, folders and export are what make that history reusable.

Step by step

A developer workflow in five steps

From install to an exported fix. Steps one to four are on the free plan; the Advanced filters, Markdown export and bulk export in step five are where Premium starts.

About three minutes

  1. Install AI Toolbox from the Chrome Web StoreWorks in Chrome, Edge, Brave, Opera and Arc. Open the popup, switch the Gemini module on and approve the one-time permission for gemini.google.com.
  2. Let the index build, then create folders per repo or serviceExisting conversations are indexed locally in the background. Manage Folders, then Add: API Debug, Infra, Code Review, with subfolders per incident.
  3. Bookmark the reply that fixed itClick the bookmark icon on the message, add a note and a colour label. The Bookmarks panel lists every saved answer with its conversation title.
  4. Search before you ask againCmd/Ctrl+Shift+F, then type the error message or function name. Every matching message shows its highlighted sentence with a link into the chat, and @@ pulls that thread into a new one.
  5. Filter, then export the working fixSwitch on Advanced for exact match, Answers only and a date range. Export as Markdown for a repo wiki or Obsidian (YAML frontmatter with title, date, model and URL), JSON for automation, or TXT and PDF for documentation.

Context Mentions: type @@ to reuse a thread

Typing @@ in the Gemini composer opens the AI Toolbox Context Mentions picker listing recently used conversations, including a Manifest V3 service worker thread

The @@ picker lists recently used and recent conversations. Pick the service-worker thread from last week and Gemini gets its content as context without a paste. Free: 3 mentions a day; Premium is unlimited with several mentions per message.

The four features developers use

Search, folders, bookmarks and export, as they ship

Every capture below is the extension running inside gemini.google.com. The plan each feature needs is stated in the text.

Search

Find the fix by the error message, not the chat title

The index covers every message in your history, so a stack trace, a function name or a config key finds the reply that solved it, highlighted, with a link into the chat. Cmd/Ctrl+Shift+F opens it anywhere on gemini.google.com. Free returns five results per query; Premium adds unlimited results with exact match, role and date filters.

Folders

A folder per repository, subfolders per incident

Manage Folders holds chats in folders and subfolders with counts and breadcrumbs, filed by searching a conversation's name rather than dragging, and a whole folder exports as one ZIP. Free covers two root folders with unlimited subfolders; Premium removes the cap and adds bulk move.

Bookmarks

Keep the reply that fixed the build

Bookmark any Gemini message with a note and one of six colour labels; the panel lists them with their conversation titles and opens the chat scrolled to the message. Free: bookmarks in two conversations. Premium: unlimited.

Export

Markdown for the wiki, JSON for automation

Any conversation exports from Manage Chats as Markdown, JSON, PDF or TXT. Markdown carries YAML frontmatter (title, date, model, URL, source) and keeps fenced code blocks intact for Obsidian, Logseq or a docs site. Free exports as TXT; Premium unlocks the other formats and bulk export of a whole folder.

FAQ

Questions people ask before installing

Can I search Gemini conversations by error message or stack trace?

Yes. AI Toolbox indexes every message in your Gemini history in the browser, so a traceback, function name or config key returns each reply that contains it, highlighted, with a link into the chat. Press Cmd/Ctrl+Shift+F on gemini.google.com. Free shows five results per query; Premium shows all of them and adds exact match, Questions or Answers, and date range filters, which is what makes a punctuation-heavy stack trace findable.

How do developers organize Gemini conversations by project?

Create a root folder per repository or service and subfolders per incident or feature, then add conversations by searching their name inside the folder. The free plan includes two root folders with unlimited subfolders; Premium removes the cap and adds bulk move from Manage Chats.

Which export format should I use for code?

Markdown for a repo wiki, Obsidian or a docs site: the .md file carries YAML frontmatter with title, date, model, URL and source and keeps fenced code blocks intact. JSON when a script needs the raw messages and metadata. TXT and PDF for plain documentation. The free plan exports as TXT; Markdown, JSON, PDF and bulk export are Premium.

Does the 1 million token context window change anything?

Gemini 3.1 Pro, 3 Flash and 3.1 Flash-Lite all take up to 1 million tokens, so whole codebases and long logs fit in one conversation. AI Toolbox does not change that limit; it makes those long sessions searchable afterwards, and its Context Meter shows how much of the window the current chat has used.

Can AI Toolbox replace my IDE's AI assistant?

No. It does not write code in your editor. It is a companion to gemini.google.com that turns ad-hoc coding sessions into a searchable, exportable record, alongside whatever runs in your IDE.

Does AI Toolbox send my code anywhere?

No. The search index, folders, bookmarks and saved prompts are stored in your browser, and every search runs locally. Conversation content is never sent to our servers; the only account detail that reaches them is the email used to verify a Premium plan. PDF export is the one exception: the conversation is rendered on our server and returned without a copy being kept.

Which browsers work?

Any Chromium browser installed from the Chrome Web Store: Chrome, Edge, Brave, Opera and Arc. There is no Firefox version.
